The digital portion of the transceiver has been tested and found to comply with the limits for a Class B digital
device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses, and can radiate
radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or television reception, which
can be determined by turning the equipment on and off, the user is encouraged to try correct the interference
by performing one or more of the following measures:
- Reorientate or relocate the receiving antenna
- Increase separation between the equipment and receiver
- Connect the equipment to an outlet on a circuit different from that to which the receiver is connected
- Consult the dealer or an experienced radio/TV technician for help.
The AS WipLL system must be installed by professional and experienced technicians who are familiar with
radio frequency (RF) issues such as gains and losses, as well as local building and safety codes. Failure to do
so will void the product warranty and may expose the end user to excessive RF hazard. Regulations regarding
maximum antenna gains, power output and maximum permissible exposure vary from country to country. It is
the responsibility of the customer to operate within the limits of these regulations.
Do not connect the units to the power outlet before mounting the units and completing all communication
cabling, including antennas. Do not connect and disconnect antennas while power is on.
Inherent risks exist in operating equipment in license-exempt bands (i.e. 900 MHz). Airspan recommends that
you do not purchase or deploy any equipment that operates in license-exempt bands without first analyzing
the interference environment at each of your proposed deployment locations. Please contact your Authorized
Airspan System Integrator or Distributor if you have any questions or require assistance regarding interference
analysis. Airspan Networks will not be held responsible for product performance issues related to interference.
In environments that produce disturbances such as paging systems, Airspan recommends using a narrowband cavity filter and implementing the appropriate frequency bands (within the filter's capabilities), i.e.
building an NVRAM frequency table using only these frequencies.
Where operators come into direct contact with any piece of electronic hardware, operators must wear an ESDpreventive wrist strap.
Ensure a minimum 2-meter separation between the outdoor radios and all persons during normal operation,
and a minimum 1-meter separation between adjacently installed AS WipLL outdoor radios.
Mount outdoor radios so that their front panel ports face down to prevent water from settling on the ports. This
avoids damage to the units such as corrosion and electrical short-circuiting.
In accordance with FCC regulations for operating in unlicensed bands, BSR external antennas must provide
EIRP ≤ 36 dBm to prevent interference with other radios operating in the unlicensed band.
Maximum CAT-5 cable length between AS WipLL outdoor radios and indoor equipment is 100 meters.
Enable frequency hopping-based synchronization via the BSDU for multiple BSRs at a Base Station, as well
as synchronization between Base Stations via a GPS (refer to the AS WipLL Commissioning Manual).

Basic Design of AS WipLL Radios
This chapter describes the basic design and physical dimensions of the AS WipLL BSR, SPR, and IDR
devices.
1.1. BSR
The BSR, installed at the Base Station, is an encased outdoor radio module providing a 9 pin D-type port for
RS-232 serial interface and a 15 pin D-type port for data, synchronization, and power interfaces. The BSR is
available in two models: BSR with an integral antenna (BSR 900 MHz TDD V-pol); BSR with two N-type ports
(displayed below) for attaching up to two external antennas (BSR 900 MHz TDD Dual Ext).

Site Preparation and Planning
When preparing and planning the site, ensure the following:
Minimum obstructions (e.g. buildings) in the radio path between the Base Station radio (i.e. BSR) and the
subscriber radios (i.e. SPR/IDR).
Minimum incursions on Fresnel Zone (recommended minimum of 60% clearance of first Fresnel Zone).
Minimum multipath fading: Some of the transmitted signals may be reflected from a nearby building, by
water under the signal path, or from any other reflectors. This reflected ("bounced") signal can then be
received by the radio receiving the signal and superimposed on the main received signal, thereby,
degrading the signal strength. Airspan recommends installing the outdoor radios at the rear of the
building’s roof instead of the front. When you install at the rear, the front of the building blocks incoming
signals from multipath reflections.
Clean frequencies selected from Spectrum Analyzer results (see Chapters 9 and 13).
Maximum received signal strength (RSS) at CPE by antenna alignment: For the IDR, RSS can be
measured by the IDR's built-in RSS LEDs; for the SPR, RSS can be measured by Airspan’s WipConfig
program or by connecting Airspan's RSS LED Plug Adapter.
Radios are mounted as far as possible from sources of interference that could degrade performance of
radio. Ensure a minimum of 1-meter separation between co-located outdoor units.
Radios mounted as high as possible to avoid obstructions and to increase link quality.
BSR and SPR/IDR are within maximum range of reception.
Maximum length of 100 meters CAT-5 cable connecting outdoor radio units to indoor terminating units.
Sufficient wiring conduit and cable ties to channel and protect the CAT 5 cable connecting the outdoor
radio to the indoor hub/switch.
Required power source is available at the site.

External Antenna Considerations
This chapter discusses main issues when using third-party external antennas.
Notes:
1) To avoid unnecessary RF cable loss, use short-length cables and with low attenuation.
2) Antennas should have a VSWR of less than 1:1.5.
3) Ensure BSR and SPR/IDR use the same antenna polarity.
4) When using an omni-directional antenna, choose a type providing a wide vertical beam width of at
least 8° to allow connection of nearby CPEs.
5) Antennas must be DC grounded.
6) In accordance with FCC regulations for operating in unlicensed bands, BSR external antennas must
provide an EIRP of less than or equal to 36 dBm to prevent interference with other radios operating in the
unlicensed band.
In some scenarios, where capacity demand is relatively low, external omni-directional antenna use at the Base
Station may seem attractive. However, it is recommended to avoid using omni-directional antennas (if
possible), due to the following disadvantages that these antennas pose compared to directional antennas:
Higher sensitivity to external interferences.
Higher sensitivity to multipath, resulting in the following:
The root mean square (RMS) delay spread at the Base Station is substantially higher.
Multipath interference at the CPE side (when using omni-directional antenna at the Base Station) is
substantially higher. In fact, when using an omni-directional antenna, the existence of clear Fresnel
zone between BSR and SPR/IDR is insufficient to eliminate multipath interference, since multipath, in
this case, can be caused by reflections originating from obstacles outside the Fresnel zone.
Higher sensitivity to alignment. Since the omni-directional antenna gain is achieved by narrowing the
vertical beam width, a relatively low deviation in the antenna alignment will result in severe signal
attenuation

Transmit Power and Cable Loss
Airspan’s AS WipLL radios provide transmit power compensation for power attenuation caused by cable loss
(of cable connecting to external antenna). Cable loss is the loss of radio transmit (Tx) power as heat, and
directly proportional to cable length and quality, and operating frequency. In accordance with FCC regulations,
when operating in unlicensed bands, the external antennas must provide an EIRP of ≤ 36 dBm to prevent
interference with other radios. EIRP is defined as max. Power Output plus (+) Antenna Gain minus (-)
Cable Loss. Therefore, to adhere to this EIRP limitation, when purchasing antenna cables, take into
consideration cable loss per cable length. The table below lists examples of cable loss per cable length.
The following procedure describes how to configure (using WipManage) BSR transmit power for 23 dBm when
using a 40-foot cable with a 4-dB cable loss.
To define BSR transmit power taking into consideration cable loss (using WipManage):
1. In the BSR Zoom window, from the Configuration menu, point to RF, and then choose Power Settings.
Power compensation
due to cable loss
2. Ensure the Power Management Mode Active check box is cleared. On the Power Level slide ruler,
define the BSR’s maximum power level, e.g. 23 dBm.
3. In the Loss Compensation field, enter the power to compensate for power attenuation due to cable length
(i.e. cable loss compensation), e.g. 4 dB.
4. Click Apply, and then reset the BSR to apply the new power settings.
Therefore, taking cable loss into consideration, the total power level of 27 dBm (23 plus 4) is achieved.
Notes:
1) Airspan does not supply external antenna cables. It is the responsibility of the installer to provide the
cable and ensure the cable characteristics (e.g. length and cable loss) enables adherence to FCC's
regulations concerning maximum EIRP (i.e. of less than or equal to 36 dBm).
2) AS WipLL 900 MHz is capable of transmitting at up to 30 dBm. However, in accordance with FCC
regulations, transmit power is limited to 23 dBm in the 4 Mbps mode, and 18 dBm in the 3 Mbps mode.

Mounting the Outdoor Radio Units
This chapter provides a brief description on how to mount the outdoor units.
5.1. Pole Mounting
The BSR and SPR can be pole mounted to avoid radio wave obstructions between BSR and SPR. The
supplied pole-mounting bracket is designed to support the BSR/SPR on a round pole of 45mm diameter.
Locking Holes
BSR mounting
Bracket
Pivot Hole
Clamping Bracket
‘U’ Bolt
To pole mount the BSR/SPR:
1. Attach the mounting bracket to the BSR/SPR using two stainless steel bolts.
2. Attach the clamping bracket to the mounting bracket using two M8-stainless steel bolts.
3. Attach the Clamping bracket to the pole by placing the two U-bolts around the pole, and then inserting the
U-bolt through the Clamping bracket and securing it by screwing the two bolts on the U-bolt.
4. Adjust the vertical position of the BSR/SPR. Lock the BSR/SPR at the desired position by inserting the
locking bolt in the desired position. Once the correct angle has been set both bolts must be tightened to
lock the BSR/SPR bracket in place.
5. Adjust the BSR/SPR horizontal position by rotating the BSR/SPR about the pole, and then tighten the Ubolt.
BSR/SPR positioning is obtained in two planes by adjustment of the mounting bracket assembly as shown
in the figure below.
13070311-01
11
5.2. Wall Mounting
The BSR and SPR can be fixed to a wall.
To wall mount the BSR/SPR:
1. Place the mounting bracket in the desired position on the mounting surface (i.e. wall), and then use a
pencil to mark the position of the four mounting holes.
2. Drill holes for each hole that you marked in the step above.
3. Insert wall anchors into each of the drilled holes. Ensure that the distance between the holes’ centers are
120 mm (top and bottom parallel holes) and 60 mm (left and right parallel holes).
4. Align the mounting bracket’s four holes with the wall anchors, and then insert a screw through the
mounting bracket holes into each wall anchor, and secure by tightening.
Note: Airspan does not provide screws for attaching the mounting bracket to the wall. The screw size
depends on the structure of the building to which the bracket is to be attached. When selecting screw sizes,
consideration must be given to the weight of the BSR/SPR and load that may be induced in windy
conditions.
5. Attach the BSR/SPR to the mounting bracket using the two stainless steel bolts (supplied), washers, and
nuts as shown in the figure below.
6. Adjust the horizontal positioning of the BSR/SPR, and then tighten the two stainless-steel bolts. Rotation is
restricted to the horizontal plane only, as shown below.

Initial Configuration
To successfully establish an air and network link between the BSR and SPRs/IDRs, the following initial
configuration settings (using WipConfig) must exist:
Correct IP and subnet addresses configured (according to your network addressing scheme)
Correct BSR's Air MAC address configured for BSR
Correct BSR's Air MAC address assigned to SPRs/IDRs
Identical frequency table configured for BSR and SPRs/IDRs
Identical maximum transmission rate configured for BSR and SPRs/IDRs
Identical mode (i.e. router or bridge) configured for BSR and SPRs/IDRs
Notes:
1) For establishing a link in bridge mode, ensure IP addressing scheme enables IP connectivity between PC
and devices.
2) For establishing a link in router mode, refer to the AS WipLL Commissioning Manual.

left-most bytes, and not the least significant bytes (LSB), e.g. the right-most bytes. For example, a typical Air
MAC address would be “AB00”, where the zeros represent the LSB.
2) To ensure each BSR has a unique Air MAC address, ensure the two left-most significant bytes are
different between BSRs, for example, 1000 and 2000. In this way, the AS WipLL system can support 256
different BSRs in the same sector (or area).
Frequency Table ID: enter frequency table number used by BSR (0 through 63), e.g. 1
Note: Frequency tables 0 through 31 are read-only (i.e. in ROM); frequency tables 32 through 63 are stored

Analyzing the RF Spectrum
Before setting up your wireless link between Base Station and subscribers, Airspan recommends analyzing
the RF spectrum at the Base Station to select only clear frequency channels (i.e. without interferences) for
building a frequency table for the wireless transmission.
Airspan recommends using frequencies that are approximately 28, 20, and 12 dB above interference levels to
effectively operate in 8- (4 Mbps/3 Mbps), 4-(2 Mbps), and 2-level FSK (1.33 Mbps/1 Mbps), respectively.
Notes:
1) Airspan’s Spectrum Analyzer feature, which plugs into WipConfig, is license-dependant.
2) Ensure all other AS WipLL devices are powered off, except the device whose spectrum you are analyzing.
3) Mount the AS WipLL device prior to commencing the spectrum analysis.
4) The spectrum analysis should be performed in continuous mode for at least 20 times. The longer you
perform the sweep, the more reliable results are obtained as interference in the ISM band can change
throughout the day or change rapidly (e.g. in frequency hopping systems).
5) To ensure locating clear frequencies, continually narrow down the sweep frequency range. For example,
first sweep a large frequency range. Once you have selected a clear area from this initial sweep, run another
batch of sweeps concentrating on these selected frequencies. The fewer frequencies the more reliable the
analysis for capturing bursty, intermittent transmitters (e.g. pagers).
6) When using external antenna, ensure correct Antenna Gain is defined with consideration to RF cable loss.
7) As interference depends on geographical locations, it is recommended to perform spectrum analysis at the
CPE location when installing the AS WipLL IDR device.
9.1. Accessing the Spectrum Analyzer
You can access the Spectrum Analyzer through either a serial or an IP network communication mode.
To access the Spectrum Analyzer:
1. Start WipConfig and then connect WipConfig to the BSR by performing one of the following:

Receiving Traps
As an SNMP-based application, the WipManage management station can receive traps generated internally
by WipManage and generated by AS WipLL devices. To receive these traps you need to perform the following:
Define management stations (by IP address) for receiving device-generated traps
Enable WipManage to receive (and display) traps
12.1. Defining Management Stations for Receiving Device-Generated Traps
Up to five management stations can be defined for receiving traps. These stations need to be defined per AS
WipLL device type (i.e. BSR, BSDU, and SPR/IDR). You can also define the trap SNMP community string that
you want the management station to receive. This is relevant only for third-party SNMP external management
stations (e.g. HP OpenView); WipManage management stations receive traps regardless of community string.
To define a management station for receiving traps (e.g. for the BSR):
1. In the BSR Zoom window, from the Configuration menu, choose Managers Table; The Managers Table
dialog box appears, as displayed below.
2. Click Add; The Manager Entry - Add dialog box appears, as displayed below.
3. In the IP Address field, enter the IP address of the WipManage interface configured for the computer on
which WipManage is running.
4. Click OK.
Note: WipManage always receives internal traps that are generated by WipManage (i.e. no need to define
management station).

Building Frequency Table Based on
Spectrum Analyzer Results
Once you have established an initial wireless link between Base Station (i.e. BSR) and subscriber sites (i.e.
SPRs/IDRs) using the default ROM frequency table, you can define a new frequency table based on clearer
frequencies for better wireless communication based on the Spectrum Analyzer results.
When the Spectrum Analyzer graph displays “spikes”, this generally indicates interference (i.e. frequencies
that should be excluded). Note that normal “noise” level is approximately –112 dBm (referred to as Thermal
Noise). Airspan recommends using frequencies that are approximately 28, 20, and 12 dB above interference
levels to effectively operate in 8, 4, and 2 level FSK (4 Mbps/3 Mbps, 2 Mbps, and 1.33 Mbps/1 Mbps),
respectively. AS WipLL can operate in 2, 4, and 8 level FSK with signal strengths greater than -90, -83, and 75 dBm, respectively.
In the unlicensed bands, Airspan recommends increasing frequency allocations as much as possible
between multiple BSRs with adjacent and overlapping sectors, or when using omni-directional antennas. This
prevents more than one BSR transmitting on the same frequency at any given time, which can result in radio
interference causing communication loss between BSR and its SPRs/IDRs. Airspan recommends a minimum
separation of 4 MHz between these adjacent BSRs. In addition, when operating in the ISM band, it is
recommended to use as many frequencies as possible to increase immunity to random interference.
Airspan allows you to define up to 32 NVRAM frequency tables using WipManage. These frequency tables
can consist of multiple frequencies for frequency hopping-based wireless communication. These NVRAM
frequency tables can be defined in WipManage using one of the following methods:
Normal: frequencies entered manually
Gap Algorithm: frequencies calculated automatically based on certain user-defined parameters
Notes:
1) For Normal frequency tables, the NVRAM frequency tables support a maximum of up to 388 bytes. Gap
frequency tables are unlimited with regards to bytes.
2) For normal frequency tables, at least 9 frequencies must be entered. Therefore, if less than 9 frequencies
are used, the frequencies must be entered repetitively (and in the same order) until at least 9 frequencies are
entered and the series is complete. For example, if only five frequencies are used, e.g. F1, F2, F3, F4, and
F5, the frequencies must be entered as such: F1, F2, F3, F4, F5, F1, F2, F3, F4, F5 (i.e. at least 9 entries -- in
this case 10 entries to complete the series).
13.1. Adding BSR Frequency Table
The first step is to add a frequency table for the BSR.
To add a Normal frequency table (using WipManage):
1. In the BSR Zoom window, from the Configuration menu, point to RF, and then choose NVRAM Frequency
Tables; The NVRAM Frequency Tables dialog box appears.
2. Click Add; The NVRAM Frequency Table Add dialog box appears.
13070311-01
31
3. In the Insert New Table to field, enter the frequency table’s index number (32 to 63). If you do not enter a
number, WipManage automatically assigns it the next available consecutive frequency table index number.
4. Add each frequency by selecting each frequency In the Valid Frequencies pane, and then clicking the left
arrow to add the frequency to the Frequency Table pane (i.e. left pane).
5. Click OK; The Frequency Tables Add dialog box closes, and the added frequency table appears in the
Frequency Tables dialog box, as displayed below.
13.2. Adding SPR/IDR Frequency Table and Assigning to other SPRs/IDRs
The BSR and the SPRs/IDRs must use the same frequency table (i.e. same frequency table index and
comprised of the same frequencies). After you have defined the NVRAM Frequency Table for the BSR, you
need to add an identical frequency table to at least one SPR/IDR, and then assign this frequency table to the
remaining SPRs/IDRs.
To add the same BSR NVRAM Frequency table to associated SPRs/IDRs (using WipManage):
1. Add an NVRAM frequency table identical to the BSR’s table to an SPR/IDR. This is similar to adding
frequency tables for the BSR (see Section 13.1, "Adding BSR Frequency Table"), but performed in the
SPR Zoom window.
2. In the BSR Zoom window, from the MultiDevices menu, point to RF, and then choose Frequency Tables;
The Multi SPRs Frequency Tables dialog box appears.
32
13070311-01
3. Select the SPR/IDR for which you added the NVRAM frequency table (in Step 1); The selected
SPR’s/IDR's NVRAM Frequency table appears in the Frequency Tables list, located in the upper pane.
4. Select all the SPRs/IDRs by clicking the Select All button.
5. Click Apply; The Multi-Apply Confirmation box appears.
6. Click Apply; The NVRAM Frequency table of SPR/IDR 10.0.0.20 is copied to the other SPRs/IDRs
indicated by all the SPRs/IDRs having identical values in the Hashed Table field.
Frequency table ID
(32) applied to
all SPRs/IDRs
All SPRs/IDRs have
identical Hashed Table
values
13.3. Selecting the Frequency Table for Communication
Once you have added the frequency tables to the BSR and SPRs/IDRs, you need to instruct the devices to
use this specific frequency table. This is performed by instructing the BSR which frequency table to use.
To select the frequency table ID (using WipManage):
1. In the BSR Zoom window, from the Configuration menu, point to RF, and then choose Hopping
Configuration; The Hopping Configuration dialog box appears.
Entering Frequency
Table ID
2. In the Frequency Table ID field, enter the ID number of the frequency table that you added to the BSR
and SPRs/IDRs, i.e. #32. Note that the current frequency table ID is #1, which was configured when
initializing the BSR using WipConfig (see Section 8.2, "BSR Initialization").
3. Click Apply; A message appears informing you change will take affect only after resetting the BSR.
4. Click OK, and then click Close to close the Hopping Configuration dialog box.
5. Reset the BSR.
13070311-01

Testing Link Quality
Once you have established your wireless link between the BSR and SPR/IDR and assigned a new frequency
table consisting of “cleaner” frequencies, it is recommended to test the link’s bandwidth performance (i.e.
Mbits/sec) in one of the following ways:
Connect a PC to the SPR/IDR and run three to four simultaneous FTP sessions to an FTP server that is
physically connected to the BSR’s LAN port (e.g. Microsoft IIS, and Linux FTP built-in servers). The few
concurrent sessions eliminate the Slow Start phenomenon (succinct explanation can be found in RFC
#2001). During the test, record the RSS and BER levels for the BSR and SPR/IDR. This information is
useful to Airspan’s technical support team for future diagnosis.
Using the Iperf application (free download at http://dast.nlanr.net/Projects/Iperf/). A simple batch file can
be made for the client side (behind the CPE) and for the BS side (behind the BSR) to ease the throughput
measurement procedure.

Troubleshooting
This chapter describes problems that you might encounter when using WipManage.
15.1. No PC-BSR Network Link
Solution
• Ensure the BSR is receiving power (from the BSDU or SDA).
• Check IP connectivity with BSR by pinging the BSR (MS-DOS command: ping –t <BSR’s IP address>) from
the PC.
• Check the PC’s network IP addressing configurations (e.g. IP address, subnet mask, and default gateway).
15.2. No BSR-SPR/IDR Air Link
Solution
• Ensure that power is received by the SPR/IDR.
• Ensure version disk file/ROM (VDF) for BSR and SPR/IDR are identical. If not, this may result in BSR and SPR/IDR
using different frequencies (even if Frequency Table ID is the same). These frequencies are ROM Frequency tables
(0-31). If the VDFs differ, then define an NVRAM frequency table (32-63) that is the same for the BSR and SPR/IDR.
• Ensure BSR and SPR/IDR have identical maximum transmission rates (e.g. 3 Mbps or 4 Mbps).
• Ensure that the BSR’s Air MAC address is defined correctly in the SPR/IDR.
• Ensure that the SPR/IDR index number in the SPR/IDR is defined correctly (e.g. if the index was defined as 2 in
WipConfig, then in WipManage, add the SPR/IDR to index icon #2).
• Ensure that the external antenna is connected (if an external antenna exists).
• Ensure that the distance between the BSR and SPR/IDR is in range for RF communication.
• Ensure that no obstacles (e.g. buildings) between BSR and SPR/IDR that may block transmission path.
15.3. No PC-SPR/IDR Network Link
Solution
• Ensure that WipManage’s management IP address is correct.
• For AS WipLL in the IP router mode, check that the routing table is correctly defined.
• For AS WipLL in the transparent bridge mode, delete the ARP table (MS-DOS command: ARP –d).
• Ensure that the SPR/IDR and BSR are configured for identical modes (e.g. IP Router or Transparent Bridge).
• Check PC’s routing table for correct routes from BSR to SPR/IDR (MS-DOS command: route print):
• For AS WipLL in the transparent bridge mode, check PC’s routing table for correct routes from BSR to SPR/IDR
(MS-DOS command: tracert <SPR’s/IDR's IP address>.
• If all the above routing verifications are correct, and still no successful network link is established with the SPR/IDR,
then reset the SPR/IDR to factory defaults using WipConfig, and then reconfigure the SPR/IDR. Resetting the
SPR/IDR to factory default ensures that your configuration settings will be correct.
