Logging In

The radios are shipped from the factory without preset passwords; click the OK button to log in at the Admin level.

Elements Common to All QuickBridge Manager Windows

Tabs

Tabs available through the Tsunami QuickBridge Manager appear following the window header on all QuickBridge Manager windows. The following figure shows the tabs before you log on to a particular radio. At this point, you can view only the list of discovered radios and information about Tsunami QuickBridge Manager.

Once you have logged in, the Connection tab indicates the IP address of the selected radio being managed by QuickBridge Manager and the tabs you can access to configure the selected radio.

The selected tab is highlighted; for example, when you click on the Link Status tab, the tabs appear as follows:

Link Status LEDs

LEDs indicating status of the local and wireless links are displayed at the bottom of all QuickBridge Manager windows.

• A green Local Link LED shows a link between the PC used to configure the radio and the local radio has been established

• A green Wireless Link LED shows that an authenticated link between the two radios has been established

• Red LEDs indicate a link has not yet been established for the local or wireless connection.

Configuring Settings

To change settings, click the Settings tab and the Radio sub-tab. (The exact window layout depends upon which unit is selected (Master or Slave) and the radio model.) If the wireless link is established, you can select either the Local or Remote device to control from the Selected Radio box.

Select the settings you want to define for the radio; click Save to save your settings.

Saving Configuration Changes

The Configuration sub-tab contains three buttons: Restart, Refresh, and Save.

• To save your configuration changes, click Save.
• To refresh the screen to the last saved configuration, click Refresh.
• Restart causes the radio to reboot.

Local and Remote Configuration Changes

The following table indicates whether the value for each field can be configured on the Local unit, the Remote unit, or both units.

Field	Operation	Reset
Master-Slave (or Primary-Secondary)	BOTH, REMOTE	Yes
Channels	BOTH, REMOTE	Yes
Frequency	BOTH, REMOTE	Yes
Antenna audible	LOCAL	No
Antenna pointing	LOCAL	No
IP address	LOCAL	No
Subnet	LOCAL	No
SNMP Community String	LOCAL	No
Default Gateway	LOCAL	No
Security	BOTH, REMOTE	No
Throughput Setting1	BOTH, REMOTE	Yes
Ethernet Protocol Support	BOTH, REMOTE	No
Enable GPS	LOCAL	No

¹Changing throughput to 40 Mbps or 60 Mbps can only be accomplished on, and is only valid on, the QuickBridge II 60 Master (or Primary) unit. The Slave (or Secondary) assumes the setting of the Master/Primary.

BOTH

Indicates that the RF link is UP and secure; in this case, both the Local and Remote radios are updated with the change. If the link is down, or not secure, just the Local radio is updated.

LOCAL

Indicates that only the local radio is updated, or if remotely configured than only that radio is affected.

RESET

Indicates that the radio is reset after the update (including remote). Traffic is interrupted for all resets.

REMOTE

Indicates that, if the remote radio is configured, both radios are updated (assuming the RF link stays up and secure). This is the same as BOTH, except the user interface is operating on the Remote radio.

Link Status Tab

Reviewing the Master Unit’s Status

From the Link Status window, review the current status of both ends of the QuickBridge II link; in this case, the locally connected radio (Master) and the remote radio (Slave). This window is updated as changes occur.

Link Status Tab Field Descriptions

Node Type

Displays the Node Type setting (Master or Slave) assigned to the unit.

Link State

When the link status between the radios changes (for example, when you first power up the radios, change the radios’ configuration, and so on) the following status messages are displayed in this field:

Slave Searching for Signal:

Slave searches for an inbound signal; Master searches for an outbound signal.

Master Searching for Signal:

Master searches for an inbound signal; Slave searches for an outbound signal.

Inbound fine sync:

Indicates inbound signal detected and link is being “finalized.”

Link established:

Indicates link established between radios.

ODU not connected:

Indicates that there is no local link between the PC and the radio. See “Section 7. Troubleshooting” for possible causes and solutions to the problem.

Throughput Setting

Shows the current Throughput Setting at which the link is operating.

Frequency Channel

Shows the Frequency setting specified for the local radio. Set both radios to the same Frequency (for example, if the Master is 3A, the Slave also should be set to 3A).

Receive Signal Level (dBm)

Shows the level of signal received by the local radio (in dBm). The signal quality should be at least 10 dB above the threshold for the throughput level you are using. See Technical Specifications, for the thresholds associated with each data rate. You can use this field to fine-tune radio alignment. After you mount the radio outdoors, check the Receive Signal Level value as you make fine adjustments to the radio alignment until you obtain optimal signal quality.

Transmitter Level (EIRP, dBm)

Shows the level of signal transmitted by the local radio (in dBm).

Packet Loss Rate

Shows the rate of packet loss. This is expressed as “X e- Y”, exponential notation, meaning that approximately X packets out of 10^Y received are in error. This is used as a general indicator of the link quality. For example, “3e-5” indicates that approximately three packets in every 100,000 received is in error.

Range km

Shows the estimated distance (in kilometers) between the two radios. Measuring the delay between two sides of a link, a value of “0” indicates that the radios may be too close together for efficient data communication.

Ethernet Activity / Ethernet Detection

Indicates whether the Ethernet link has been detected (auto-negotiate has completed) and whether it is active.

GPS Status

This field has been added to support the installation of GPS antennas. Possible values are Disabled or Enabled. This field is grayed out if GPS is not supported by your QuickBridge II radio.

Settings Tab, Radio Sub-Tab

Selecting Node Type

You can switch between configuration of the Master unit and the Slave unit by clicking the radio button next to Master or Slave.

Changing the Throughput Setting

You can change the throughput setting for the selected radio by clicking the radio button next to one of these selections: 18 Mbps, 34 Mbps, or 54 Mbps. A possible reason for changing this setting is to reduce throughput to increase the range of reception.

Reassigning the Frequency Plan

The Frequency Selection consists of two components—a Channel and a Frequency. Throughout this document, these two settings are collectively referred to as the Frequency Plan. The Frequency Plan box lets you choose the Frequency Plan to be used for the selected radio. See Available Frequency Plans for available frequencies. Choose the same Frequency Plan for both radios.

You can leave the Frequency Plan unchanged and proceed with the installation, or you can change the Frequency Plan (now or at any later time). Generally, for a single hop of radios, any of the seven frequency channels (3A, 3B, 3C, 4A, 4B, 4C, or 4D) can be selected. Once a link has been established, changing the frequency plan of either Master radio (when locally connected to the Master) causes the frequency plan of the Slave radio on the other end of the link to change as well.

Changing Frequency Plans is especially useful when installing multiple QuickBridge II units at the same location.

Click the Settings tab and the Radio sub-tab to reassign the frequency plan. To select a new frequency plan, click on one of the other buttons for the other frequency channel not marked.

Available Frequency Plans

The QuickBridge II offers two channel plans, each with non-overlapping frequencies, as defined in the following tables. The 26 dB bandwidth of the RF signal is less than 26 MHz. Each channel is 20.75 MHz wide at the 3 dB point.

3-Channel Plan			4-Channel Plan
Channel ID	Frequency		Channel ID	Frequency
3A	5742.20 MHz		4A	5743.86 MHz
3B	5775.40 MHz		4B	5764.61 MHz
3C	5808.60 MHz		4C	5785.36 MHz
			4D	5806.11 MHz

Selecting Ethernet Protocol Support

In the Ethernet Protocol Support box on the Radio sub-tab, you can select IP Only mode or Enhanced Ethernet mode.

Choose IP Only mode when all the bridged traffic is known to be composed of only IP or ARP packets, or protocols that use the 802.3 length field of the Ethernet Header.

Choose Enhanced Ethernet mode when the bridged traffic is known to contain packets with protocols that use 802.2 type fields (in addition to IP or ARP), such as Appletalk, IPX, 3Com 8688, and so on. Note that, with certain traffic loads, performance may be impacted.

Enabling GPS Control

If you are installing QuickBridge radios in a location where one radio could interfere with another, you can install an optional GPS antenna on each radio and enable the GPS receiver to synchronize the TDD timing to the GPS signal.

To enable GPS control, click Enable in the GPS Control box.

Aligning Antennas

Better alignment (“pointing”) of the antennas results in greater link reliability and robustness. An alignment tool is included in the QuickBridge Manager to assist with this process. It requires at least an approximate alignment of the antennas prior to its execution.

To align the radios:

From the Settings tab, click on the Installation sub-tab at the bottom of the window. Then check On in the Audible Signal-Strength Indicator box (when this option is on and the radio is in “antenna pointing mode,” the radios emit a tone. The tone increases in pitch as the radios are aligned.)



1. Click the Antenna Pointing button at the bottom of the window. A dialog box warning of the antenna-pointing mode’s out-of-service condition is displayed.

   

   ---

   CAUTION!  If the link is already established, traffic is interrupted when you enter the Antenna Pointing Program.

   ---

2. Upon acknowledging the warning, the following dialog box is displayed:

   

3. The process of achieving the best receive signal level is an iterative process: Adjust antennas one at a time and adjust for the highest possible number in the Receive Signal Quality indicator box. At longer distances, the signal can be weak, but may be adequate to establish and maintain the link.

   ---

   Note:  There is a slight delay (a few seconds) before the Receive Signal Quality bar moves to indicate adjustments to the antennas and the Receive Signal Level.

   ---

4. Select the Link Status tab to check the status of both radios. When a link is properly established, the Wireless Link indicator at the bottom of the Status screen is green. The Link State field also indicates “Link Established.”

Settings Tab, Admin Sub-Tab

Reassigning the Unit’s IP Address

Click the Settings tab and the Admin sub-tab to view or change the default current IP address. This appears in the Network box’s Radio IP Address field. Once a link has been established, you can re-assign the IP address of the remote radio. Any Class A, B, or C address is valid.

Set the local radio’s IP address to an address in the same subnet as the PC’s IP address. If you change the IP address of the local radio, you must change the IP address of the PC to an IP address in the same subnet as the radio in order to be able to use the Manager program.

To manage the QuickBridge II on the other side of a router, configure the subnet mask for the desired subnet and select a unique IP address supported on that subnet.

Specifying a Default Gateway

The default gateway defines the address of the router for your network. The default gateway for each client points to the router for that subnet. QuickBridge uses the default gateway only when sending a QuickBridge-originated SNMP trap to a trap manager that is reachable through a gateway.

For example, if you defined a subnet 192.168.1.0, and the IP address for the router on that subnet were 192.168.1.254, the default gateway for all clients in that subnet would be set to 192.168.1.254.

Assigning a Security Key ID

The Security Key is used to authenticate both radios for authorized point-to-point communication. Before setting the key, be sure the wireless link has been established. Click the Settings tab and the Admin sub-tab and enter a Security Key in the Security Key(0-16 characters): box. Click Save. With the wireless link established, the Security Key is assigned to both the Local and the Remote unit. The default Security Key is <blank> (there is no Security Key specified at the factory).

The Security Key can consist of up to 16 alphanumeric characters (a-z, A-Z, 0-9) and is case-sensitive. Non-alphanumeric keys such as * or # are not valid.

Example: ABC6543210jklmnO, or Sunnyvale94085, or BaldMountain888

This key is used to authenticate both radios for authorized point-to-point communication. Radios that do not have the same key cannot communicate with each other and will not establish a wireless link.

The default Security Key is <blank>. In other words, there is no Security Key specified at the factory.

Setting the SNMP Community String

Click the Settings tab and the Admin sub-tab to enter or change the Get and Set SNMP Community names in the Set SNMP Community String box.

SNMP delimits management domains by defining communities. Each community is identified by a name, which is an alphanumeric string of up to 255 characters defined by the user.

The Tsunami QuickBridge II SNMP agent defines strings of up to 10 characters (case-sensitive, numeric, and alphabetic).

Any SNMP entity (both managed entities and management stations) is assigned a community name by its user. In parallel, the user defines a list of the communities for each SNMP entity authorized to communicate with the entity, as well as the access rights associated with each community (this is the SNMP community name table of the entity).

Settings Tab, T1/E1 Sub-Tab

Configuring T1 and E1 Channels

You can enable up to two T1 or E1 channels, thereby allocating 13 Mbps (E1) or 17 Mbps (T1) of full duplex Ethernet capacity (aggregate capacity 26 Mbps for E1and 34 Mbps for T1) for the data connection.

The T1 or E1 channels are fully compliant to G.703 standards. The two channels are connected individually at the radio end. You must provide your own cable and define the crossover point (for T1 and E1). If you use cables that do not comply to the requirements for T1 or E1 (G.703) or do not define the crossover point, you cannot expect to achieve the published performance. Because the distance and the termination are user and site specific, installation of T1 or E1 cables are the user's responsibility.

The T1 and E1 ports support long haul and short haul input signals and can be monitored for alarms and error statistics. See Viewing Alarm Status.

Voice Channel Selection

Select T1 or E1.

Line

You can Disable or Enable the T1 or E1 line.

Code

This is the current T1 line encoding/decoding configuration for the associated channel associate. The following two values are valid for T1 channel types:

AMI

Selects Alternate Mark Inversion encoding/decoding

B8ZS

Selects the Bipolar with 8-bit Zero Substitution encoding/decoding.

AMI (alternate mark inversion) is a line code used for T-1 and E-1 lines that has a 12.5% ones density minimum, and the one conditions of the signal alternate between positive and negative polarity.

B8ZS (bipolar or binary 8-zero substitution) is an encoding method used on T1 circuits that inserts two successive ones of the same voltage into a signal whenever eight consecutive zeros are transmitted. The device receiving the signal interprets the bipolar violation as a timing mark, which keeps the transmitting and receiving devices synchronized.

AMI requires the use of 8 Kbps of the 64 Kbps of each channel to maintain synchronization. In a T1 circuit, there are 24 channels. This loss adds up to 192 Kbps, which means that in reality only 56 Kbps is available for data transmission. B8ZS uses bipolar violations to synchronize devices, a solution that does not require the use of extra bits, which means a T1 circuit using B8ZS can use the full 64 Kbps for each channel for data.

Loopback

You can Disable or Enable loopback. When loopback is disabled, this T1 or E1 interface is operating without the signals being looped back. When loopback is enabled, data received from the IP network side is looped back to the network transmit line and an unframed all ‘1’ code (AIS) is transmitted in the E1 or T1 transmission path. Only one loopback can be running from one port on each side of the link at a time. Setting a loopback while another loopback is running will stop the previously running loopback and start the recently set loopback.

Line build out

This field lets you select a line build out configuration for the associated channel. The following five values are valid for T1 channel types: 0-133 feet, 134 – 266 feet, 267 – 399 feet, 400 – 533 feet, and 534 – 655 feet.

The default value for T1 channels is 0-133 feet.

Selected Radio

Indicates when the selected radio is Local or Remote.

Configuration Sub-Tab

You can refresh default values by clicking the Refresh button. To save your configuration changes and restart the computer, click Restart.

Installation Sub-Tab

Click the Installation sub-tab when you want to use the QuickBridge Manager’s Antenna Pointing utility. See Aligning Antennas using the Settings Tab.

Upgrade Tab

Upgrading Your System’s Firmware

Occasionally, flash upgrades may be made available, offering the ability to enhance some features of your QuickBridge II equipment. To upgrade the firmware for your QuickBridge II radios:

1. Start QuickBridge Manager; connect and login.

2. Click the Upgrade tab.

   

3. Select the Local or Remote unit to which you are going to download the firmware. (The current firmware versions are displayed in parentheses following “local” and “remote”.)

   ---

   CAUTION!  When upgrading firmware from one side of the link, the remote side should always be upgraded first. Failure to do so may render the link inoperable, requiring the remote unit to be upgraded locally.

   ---

4. Click on Select and Download Code to begin the download; the Status window displays the current download progress.

5. After the progress bar indicates completion, verify that the new version of firmware is displayed in parentheses next to the local or remote selection area. (It can take up to 60 seconds for this area to be “refreshed” with the new information.)

6. Click on any other tab to exit this window when you have completed your download.

Alarm Tab

Viewing Alarm Status

About Tab

Viewing Hardware and Firmware Version Numbers

To view the levels of QuickBridge II firmware, hardware, and software in your system, click the About tab. This window also provides information about contacting Proxim Technical Support.

Management with SNMP

In addition management with the QuickBridge Manager, you also can manage and partially configure a Tsunami QuickBridge II using the Simple Network Management Protocol (SNMP). Note that this requires an SNMP manager program, such as HP Openview or Castlerock’s SNMPc.

Tsunami QuickBridge II supports several Management Information Base (MIB) files that describe the parameters you can view or configure over SNMP:

• Proxim Enterprise MIB, distributed as the file “qb.mib”
• MIB-II (RFC 1213) System and SNMP groups

Proxim provides these MIB files on the Documentation and Software CD included with each Tsunami QuickBridge II unit. You must compile the above MIBs into your SNMP program’s database before you can manage a QuickBridge II using SNMP. See the documentation that came with your SNMP manager for instructions about how to compile MIB files.

The Enterprise MIB defines the read and read-write objects that can be viewed or configured using SNMP. These objects correspond to most of the settings and statistics that are available with the other management interfaces. See the Enterprise MIB for more information; the MIB can be opened with any text editor, such as Microsoft Word, Notepad, or Wordpad.

Support for Enterprise and MIB-II traps is included; these are generated when events occur on the QuickBridge II radio. Traps can be enabled and disabled individually for customization. (See the Enterprise MIB description for more detailed information).

Troubleshooting

The following table summarizes link and other problems you might experience, along with recommended ways to solve the problems.

Problem	Possible Cause	How to Resolve

See the following sections for more detailed troubleshooting information.

Data Stream Errors and Interference

This section describes troubleshooting methods for:

• Errors in the data stream
• Counteracting and evaluating interference

Errors in the Data Stream

When the radios are in service, errors in the data stream can occur. This usually is known to the operator by either faulty data indications of downstream equipment or external bit error rate testing. The QuickBridge II employs a cyclic redundancy check (CRC) on all wireless data, strongly reducing the likelihood of such events. However, there always exists a finite probability of such events.

Some errors are exhibited on downstream data processing equipment or during an external BER test. In other cases, there may be data errors due to atmospheric conditions (fading), interference, or other reasons. In the case of these types of errors, the following information can be helpful to troubleshoot the radio link.

Indications	Possible Causes	Recommended Actions
During external BER test, test equipment indicates errors Downstream equipment (switch, router, and so on) indicates errors	·         Path fading due to atmospheric conditions ·         Continuous or intermittent interference ·         Antenna problems, misalignment, or path clearance ·         Received signal level (RSL) is too strong ·         Far-end radio transmitter circuitry is faulty ·         Near-end radio receiver circuitry is faulty	Re-align antennas   Verify 10/100 Base-T wiring

Counteracting and Evaluating Interference

Selecting a Different Frequency

The QuickBridge II radio offers several distinct non-overlapping frequency channel plans (see Available Frequency Plans). Changing the channel plan is the fastest way to determine whether interference is affecting the radio bridge. If the bridge is not operating (that is, the link is not established), you may have to change each unit’s frequency plan locally by connecting to the QuickBridge II unit directly with the PC. If the link is up, change the bridge’s frequency plan by selecting either the local or remote radio and changing the frequency plan. This changes both the remote and local units at the same time (see Reassigning the Frequency Plan).

Re-Locating Equipment/Antenna

Occasionally, interference is caused by the radio being too close to another similar transmitter. Moving the radio or the interfering equipment can reduce or eliminate interference.

Interference countermeasures rely to some extent on the measurement of the received interference level and frequency. Prior to turning up a new hop, a spectrum analyzer can be used to monitor the spectrum at each end to check for possible interfering signals. For more details, see “Using a Spectrum Analyzer to Evaluate Potential Interference.

Using a Spectrum Analyzer to Evaluate Potential Interference

Connecting a spectrum analyzer to an external antenna and using “peak hold” on, the spectrum across the receive frequency range of the radio (5725 – 5825 MHz) can be swept and any signals being received at levels above the radio’s specified threshold identified. If potential interfering signals are found, then the frequency plan can be changed to avoid a receive channel that may contain significant interference (see Configuring Settings). For example, you can reduce interference by moving from the 3A plan to the 4D plan.

Signals outside the receiver frequency range can be ignored; they will not cause interference.

When using a spectrum analyzer for determining the presence of interference, very narrow resolution bandwidth settings must be used to detect signals down to the radio’s threshold (approximately –89 dBm).

Using Short Paths

The single most effective countermeasure against interference is to maintain “short path” length. This can be achieved by dividing long paths into multiple small paths by cascading hops. Intermediate repeaters can be formed using back-to-back QuickBridge II radios.

By definition, short path is a path where fades are extremely rare and signal levels vary by no more than plus or minus 3 dB during fades. This distance varies with the RF frequency. Typically, a short path is defined as any path length shorter than 5 miles/8 kilometers at 5.8 GHz.

Site Planning

This section provides insight into the planning necessary to prepare your site for your broadband fixed wireless system.

The installation of a wireless network requires much the same basic planning as any wired network. The main difference is that the wireless signal requires some additional planning. This additional planning includes:

• RF path planning
• Site preparation
• Installation of outdoor components (such as outdoor units, antennas, lightning protection devices, and cabling suitable for outdoor conditions)

Although the technology implemented in this broadband fixed wireless system can make use of multipath signals, reducing the effect of obstructions in the path, the characteristics of the path must be examined carefully. With this knowledge, components and network requirements can be planned correctly for your specific application.

General Considerations

A basic consideration is the physical location of the sites at each end of the link. Because microwave signals travel in a straight line, a clear line of sight between antennas is necessary. Frequently, however, the locations of the desired links are fixed. When a clear line of sight cannot be achieved, you must plan accordingly.

Other questions to consider include:

• Will a tower have to be constructed? Are permits required?

• Possibility of future obstructions: Will trees grow high enough to interfere with the signal? Are there plans to erect buildings between the sites that may obstruct the path?

• Availability of grounding: Good grounding is important. In areas prone to lightning, a lightning arrestor is strongly recommended.

• Distance between the indoor portion of the system (power and Ethernet adapter) and the user’s network.

The following sections should assist you in determining which information is critical to the site and in making appropriate decisions.

Specific Site Planning

Weather

Research any unusual weather conditions that are common to the site location. These conditions can include excessive amounts of rain, wind velocity, or extreme temperature ranges. If extreme conditions exist that could affect the integrity of the radio link, you should take these conditions into consideration early in the planning process.

Rain

Except in extreme conditions, attenuation (weakening of the signal) due to rain does not require serious consideration for frequencies up to the range of 6 GHz. When microwave frequencies are at the 15 GHz range or above, attenuation due to rain becomes much more of a concern, especially in areas where rainfall is of high density and long duration. The systems discussed in this manual operate at frequencies below 6 GHz, so rain is not a concern.

Temperature

Temperature can adversely affect the radio link when phenomena such as temperature inversion or very still air accompanied by stratification occur. Temperature inversion can negate clearances, and still air along with stratification can cause severe refractive or reflective conditions, with unpredictable results.

Temperature inversions and stratification also can cause ducting, which can increase the potential for interference between systems that do not normally interfere with each other. Such effects of temperature are noticeable for path links farther than 3 miles.

Wind

Any system components mounted outdoors are subject to the effect of wind. You should know the direction and velocity of the wind common to the site. Antennas and their supporting structures must be able to prevent these forces from affecting the antenna or causing damage to the building or tower on which the components are mounted. Antenna designs react differently to wind forces. This is known as wind loading.

Lightning

You must always consider the potential for lightning damage to radio equipment when planning a wireless link. A variety of lightning protection and grounding devices are available for use on buildings, towers, antennas, cables, and equipment, whether located inside or outside the site, that could be damaged by a lightning strike.

Lightning protection requirements are based upon the exposure at the site, the cost of link downtime, and local building and electrical codes. If the link is critical and the site is in an active lightning area, attention to thorough lightning protection and grounding is critical.

Lightning Protection

To provide effective lightning protection, install antennas in locations that are unlikely to receive direct lightning strikes, or install lightning rods to protect antennas from direct strikes. Makes sure that cables and equipment are properly grounded to provide low-impedance paths for lightning currents. Install surge suppressors on adjacent telephone lines and power lines.

In regions that have extreme lightning occurrences, you should provide additional lightning protection for cables leading to the wireless radio. Place this optional lightning protection at points close to where the cable passes through the bulkhead into the building, as well as near the radio. A grounding screw is provided on the radio.

CAT5 Cable

When the entire interface cable, from the building entrance to the radio, is encased in steel conduit, no surge arrestors are required. Otherwise, each interface cable requires one surge arrestor within two feet of the building entrance.

Interference

An important part of planning your broadband fixed wireless system is the avoidance of interference. Interference can be caused by affects outside the system. Good radio frequency (RF) planning can overcome most interference challenges.

Co-channel interference results when another RF link is using the same channel frequency. Adjacent channel interference results when another RF link is using an adjacent channel frequency. In selecting a site, a spectrum analyzer can be used to determine whether any strong signals are present and, if present, determine how close they are to the desired frequency. The further removed from your proposed frequency, the less likely they are to cause a problem.

Antennas

For point-to-point applications, the narrower the antennas’ beamwidth, the better. QuickBridge II Ethernet Systems use integrated directional antennas that transmit and receive a relatively narrow beamwidth of radio energy, improving system performance by reducing the likelihood that surrounding RF clutter will interfere with reception.

The integral antennas have the following characteristics:

Type: Flat-panel antenna
3 dB Beamwidth: 10-degree
Polarization: Circular polarization, left-hand sense

Even when other licensees are not an issue, all these considerations are still important to reduce interference between your own adjacent installations. Antennas are tuned to operate on a specific group of frequencies. QuickBridge II offers two channel plans that provide a flexible tool for overcoming present and future interference.

Three or four non-overlapping channels (seven total directional channels) can be used to avoid existing traffic in the 5.8 GHz frequency band. If one part of the 5.8 GHz spectrum is occupied when QuickBridge II initially is deployed, another frequency channel can be selected to bypass the interfering signal. If interference arises after deployment, another frequency channel plan can be selected to “steer around” the impacted channel. Beamwidth and gain have been optimized in this equipment.

Towers

When planning antenna placement, it might be necessary to build a free-standing tower for the antenna. Regulations and limitations define the height and location of these towers with respect to airports, runways, and airplane approach paths. These regulations are controlled by the FAA. In some circumstances, the tower installations must be approved by the FAA, registered with the FCC, or both. To ensure compliance, review the current FCC regulations regarding antenna structures. These regulations (along with examples) are on the FCC website at http://wireless.fcc.gov/antenna/.

Path Planning

To get the most value from a wireless system, path planning is essential. In addition to the fact that radio signals dissipate as they travel, many other factors affect a microwave signal as it moves through space. All of these must be taken into account, because any obstructions in the path will attenuate the signal.

Calculating a Link Budget

A link budget is a rough calculation of all known elements of the link to determine whether the signal will have the proper strength when it reaches the other end of the link. To make this calculation, consider the following information. A signal degrades as it moves through free space. The longer the path, the more loss it experiences. This free-space path loss is one factor in calculating the link viability. Free space path loss is easily calculated for miles or kilometers.

Availability represents the quality of a link. It is the ratio of the time that the link is available to the total time. This serves as a guide to the service that you can expect, on average, over a period of one year.

Unlicensed Frequencies

U-NII

The FCC has identified the frequencies from 5.725 to 5.825 GHz as Unlicensed National Information Infrastructure (U-NII). This band can be used by anyone without having to obtain a license. However, you must use radio equipment that is “type approved” by the FCC or local government for use within the specific band. The QuickBridge II 60 and QuickBridge II 20 are type approved to operate in the U-NII band.

ISM

The FCC has identified the frequencies from 5.725 to 5.850 GHz as Industrial, Scientific, and Medical (ISM). This band can be used by anyone without having to obtain a license. However, you must use radio equipment that is “type approved” by the FCC or local government for use within the specific band. The QuickBridge II 20 is type approved to operate in the ISM band.

Antenna Height and Placement

The outdoor placement and height of the QuickBridge II radios on a tripod, mast, or pole is critical to the proper operation of the equipment to provide error-free performance.

The wireless path will suffer from poor performance (high bit error rate or even complete outage) if the path has any of the following:

• Partial line-of-sight
• Partial or complete blockage due to foliage, buildings, curvature of the earth
• Temporary blockage due to cars, trucks, planes that move into and out of the path

The height of the QuickBridge II unit must be sufficiently above the blockage so that definite clear line-of-sight is achieved, as well as clearance in the first Fresnel Zone.

The Fresnel Zone is the shape of the radio beam between the two transmitters that is determined primarily by the distance between the antennas and the frequency of transmission. The Fresnel Zone is not a straight and narrow beam like a laser, but rather “bulged” in the middle like a football. Any blockage within 60% of this “bulge” would interfere with the performance of the wireless link.

Clearance in the path is defined as consisting of:

• Vertical clearance above the ground and the highest building or objects in the signal path, and
• Horizontal clearance from neighboring buildings and objects in the signal path.

The height of each end of the QuickBridge II hop must be high enough to ensure:

• A clear line-of-sight of each end
• Clearance over and above any obstructions within 60% of the first Fresnel Zone
• Clearance above the height due to the curvature of the earth

Distance between two transmitters	0.6 x First Fresnel Zone	Earth Curvature	Total Clearance  (minimum)
0.1 mile	3 ft.	0	3 ft.
0.25 mile	4 ft.	0	4 ft.
0.5 mile	6 ft.	0	6 ft.
1 mile	9 ft.	0	9 ft.
2 miles	13 ft.	1 ft.	14 ft.
3 miles	16 ft.	2 ft.	18 ft.
4 miles	18 ft.	3 ft.	21 ft.
5 miles	20 ft.	4 ft.	24 ft.
6 miles	22 ft.	6 ft.	28 ft.

For example, for a path that is 3 miles long, the transmitters on each end of the hop must be 18 feet above any obstruction that is in the path. Therefore, if there is a 30-foot building in the middle of the path, then the two transmitters must be at least 48 ft (30 + 18 ft) above ground. This then dictates the height of the pole or mast; could be a 48 foot mast, or an 8 foot pole on a 4-story building.

Antennas should be placed with the following simple guidelines:

• Antennas must have clear line-of-sight of one another
• Mounted as high as possible above the ground to allow maximum clearance – above the actual surface of the earth, or above the height of the highest obstacle in the signal path
• Avoid trees in the signal path
• Install the unit at least 6 feet away from all other antennas
• Away from reflective surfaces such as metallic, mirror-coated glass walls, or large building walls
• Away from power and telephone lines

Weatherproofing Connections

Weatherproof outdoor connections with waterproof butyl tape, as shown in the following photos:

1. The following photo depicts the connector before weatherproofing. You will add three layers of tape; one 6-inch strip of butyl tape and two 6-inch strips of electrician’s tape are required.

   

2. First, wrap the connector using the first strip of electrician’s tape, as shown in photos 2, 3, and 4. This serves as a base for the butyl tape, letting you remove the butyl tape easily when necessary.

   

3. Next, in the same manner, apply a layer of butyl tape over the electrician’s tape, as shown in photos 5 through 8.

   

4. Finally, apply a layer of black electrician’s tape over the butyl tape for further protection, as shown in photos 9 and 10; the butyl tape alone is not UV protected.

Lightning Protection Recommendation

All outdoor electronic equipment is susceptible to lightning damage. Proper grounding to national and local codes is instrumental in providing human safety. Lightning Protection is used to maximize the reliability of the electronic system by diverting the excess energy that can be induced on any transmission lines (data, power) through a series of surge protection devices. The energy is dissipated through heat and also diverted to ground.

What Protection is Provided?

All Tsunami QuickBridge radio units have built-in lightning protection on both the power supply lines and the Ethernet lines. There are TVS diodes that provide protection to IEC 61000-4-05. Proxim Corporation uses “well-design” practices incorporating these devices in the Tsunami QuickBridge products.

Why is Additional Protection Recommended?

Lightning, even with the built-in protection, can still damage outdoor Tsunami equipment. This can occur for any number of reasons, such as an improperly grounded installation, or when the amount of transient energy from nearby lightning exceeds what the devices can handle.

If a Tsunami unit fails due to damage from lightning, the link is out-of-service until the unit is replaced or repaired. An external, revertive protection device can provide a higher level of protection and greater probability of surviving lightning transients without damage to the Tsunami equipment. If damage does occur, most likely it is to the lightning protection devices and not the Tsunami equipment. Remember, even with external lightening protection, damage can still occur to the Tsunami outdoor units.

What Protection is Recommended?

Proxim recommends the following for its QuickBridge products:

PolyPhaser CAT 5 Data Protector

This is a heavy-duty aluminum, weather-tight enclosure for outdoor use that serves to protect wireless outdoor units, as well as the indoor power & Ethernet adapter and connected line equipment inside the roof penetration. This product can be used for all CAT 5 cable lengths up to 100 meters from the outdoor wireless unit to the indoor power & Ethernet adapter.

The Polyphaser Data Protector uses Cascade Technology. This is a multi-stage technology that is superior to single stage because of high surge current capacity and fast response time.  The unit is designed to fit in-line onto the outdoor CAT 5e cable, using two weatherized plug openings for the cable to enter and exit.  The existing cable is cut, dressed, and reconnected onto two sets of 8 screw terminals inside the Data Protector.

Transtector Systems Surge Supressor

This outdoor-use, molded plastic, weather-tight enclosure is a surge suppressor designed to protect the QuickBridge II unit from lightning damage. This product can be used for CAT 5 cable lengths up to 50 meters from the outdoor wireless unit to indoor power & Ethernet adapter.

The 1101-TSU uses silicon avalanche suppression diodes (SASD) to provide lower voltage protection level (VPL).  This technology provides a superior protection level over traditional gas tube type devices.  The unit is designed to fit onto a CAT 5 cable in a pass-through configuration.  The input and output connections can be made at two sets of 8-screw terminals, or two 8-pin DIN style connectors.  This arrangement allows the installation of the connectorized CAT 5e cable directly into the Surge Suppressor, or with a cut cable.

How are the Lightning Protection Units Connected to the CAT 5 Cable?

The lightning protection units recommended are designed to be installed in-line onto the CAT 5e cable that connects the outdoor QuickBridge unit to the indoor power adapter.

The lightning protection device has a Surge (cable-facing) side, and an Equipment (equipment-facing) side. The Equipment side faces the outdoor QuickBridge unit or the indoor power & Ethernet adapter. The Surge side faces the long length of cable; when installing two lightning protection units, each unit’s Surge side face one another.

See pin-out information for each unit in “Protection Unit Specifications” for connecting the cable to the protection device.

Where Should the Protection Units be Located?

At least one unit should be installed near every outdoor QuickBridge unit.  General guidelines are:

• Locate protector as close to the outdoor QuickBridge unit as possible, where the lightning protection unit can be securely mounted to a flat surface and grounded properly. Ideally, this should be no further than five feet away from the unit.

• Locate one protector at the roof penetration point, outside, so that the cable immediately enters the building after the protection unit. This protector is optional if the distance from the first unit to the roof penetration point is relatively short (under 15 feet).

Installing two protectors provides the maximum protection against lightning damage to the outdoor QuickBridge II unit and the indoor power & Ethernet adapter, especially if the CAT 5 cable length is greater than 15 meters.

The QuickBridge contains two complete radio units. A total of two or four lightning protection units should be ordered per QuickBridge link.

Security

The QuickBridge II provides ways to prevent unauthorized users from communicating with the QuickBridge II unit. You can password protect the system to prevent unauthorized users from accessing the system. Also, you can use the Link Security Key to scramble the transmitted signal, preventing unauthorized units from detecting the signal.

Password Protection

The QuickBridge II provides two levels of password protection:

User level

Lets the user display the system’s current status only.

Admin level

Lets the user display the system’s status and change its configuration.

The default password is <blank>. By default, password protection is turned off. Password protection for either password level (user or admin) can be turned on and off.

Passwords can be from 1 to 16 characters; any combination of alphanumeric characters are allowed.

Specifying a User-Level or Admin-Level Password

To define the password for either access level from the QuickBridge Manager:

1. Select the Connection tab and Login to the radio you want to change (if not already logged in).

   

2. Click the Admin Level button.

   

3. Select the level of password you wish to modify from the drop-down menu: User Level or Admin Level.

4. Enter the current password in the current password: field (leave blank if never set), then enter the new password twice in the fields provided.

   

5. Click OK; the following message box is displayed:

   

6. After entering the new password, select Logout.

7. Login with the new password.

    

   Upon successful login, the Link Status window for the selected radio is displayed.

   

Turning Off Password Protection

To turn off password protection, reset both passwords to <blank>. Do this by returning to the Security window and entering the current password while leaving the two new password entries blank (for both the User and Admin access levels).

Logging In

If a password has been specified for the access level you desire, you must log in to the system with the appropriate password.

Security ID on the QuickBridge II Link

Wireless transmissions on the QuickBridge II employ PN scrambling whereby all emissions are "shuffled." The shuffling method is uniquely determined by the 16-character security key so that the receiving device can correctly "un-shuffle" the transmission. With a mismatched security key, the shuffled transmissions are unusable to the device attempting to receive the signal.

The 16-character Security Key is user-defined using the QuickBridge Manager program. The two keys, set for both the Master and Slave units, must match before a link can be established. The ID code is made up of 0-9, a-z, and A-Z characters. In addition, the two units must match frequency plans and one must be designated a “Slave” and the other must be “Master”. Two Slaves cannot talk to one another, and two Masters cannot talk to another.
