Installing the BSR
This chapter describes the installation of the WipLL Base Station Radio (BSR),
which is installed at the Base Station.
Warning: This device must not be co-located or operating in conjunction with
any other antenna or transmitter.
Note: The maximum cable length between the BSR and terminating equipment
is 100 meters.
6.1. Basic Design and Physical Dimensions
The BSR is encased in a chassis providing access to the BSR’s communication ports
on the front panel. The BSR’s bottom panel provides holes for mounting the BSR to,
for example, a pole or wall.
The BSR provides the following ports:
9-pin D-type: RS-232 (serial) interface
15-pin D-type: data, synchronization, and power interface

6.2.1. Minimum Distance Between BSRs
To prevent radio interference, each BSR requires a minimum of 1-metre separation
between adjacent BSRs (see Figure 6-3).
1 Metre min.
Figure 6-3: Minimum separation between mounted BSRs
Warning: To avoid RF interference between BSRs operating in the 700 MHz,
where four BSRs are installed at a Base Station, a 1-meter separation must be
provided between the antennas of the BSRs operating in the lower frequencies
(i.e., 711.5 and 714.5 for 1 Msps mode; 712 and 714 for 1.33 Msps mode) and
the antennas of the BSRs operating in the upper frequencies (i.e., 741.5 and
744.5 for 1 Msps mode; 742 and 744 for 1.33 Msps mode).
Warning: The BSR emits microwave radiation; a minimum distance o
f
200 mm must be maintained from the front of the BSR. However, for the 700
MHz band (i.e. WipLL 700), when external antennas are used, a minimum
distance of 800 mm must be maintained from the front of the device.

Hardware Installation Guide Installing the BSR
6.3. Connecting Third-Party External Antennas
(Optional)
A third-party external antenna can be attached to the BSR model providing an N-
type port. The addition of an external antenna allows greater RF sector coverage
than the standard BSR Internal Antenna model (i.e., 60°). The BSR with an external
antenna is especially suited for Base Stations with one BSR, where sector coverage
can be increased to 360° by using an omni-directional antenna.
The BSR model for the 900 MHz and 700 MHz bands provide two N-type
connectors for attaching two external antennas. This provides dual-antenna diversity.
Warning: It is the responsibility of the person installing the WipLL system
to ensure that when using the outdoor antenna kits in the United States (o
r
where FCC rules apply), that only those antennas certified with the product are
used. The use of any antenna other than those certified with the product is
expressly forbidden in accordance with FCC rules CFR47 part 15.204. The
installer should configure the output power level of antennas according to
country regulations and per antenna type.
Warning: For WipLL 700 MHz, where four BSRs are installed at a Base
Station, a 1-meter separation must be provided between the antennas of the
BSRs operating in the lower frequencies (i.e., 711.5 and 714.5 for 1 Msps
mode; and 712 and 714 for 1.33 Msps mode) and the antennas of the BSRs
operating in the upper frequencies (i.e., 741.5 and 744.5 for 1 Msps mode; and
742 and 744 for 1.33 Msps mode).
Warning: In accordance with FCC regulations, ensure that when operating in
unlicensed bands, the external antennas provide a maximum EIRP of 36 dBm
to prevent interference with other radios operating in the unlicensed band. The
EIRP is defined as:
Max. Power Output + Antenna Gain + Cable Loss ≤ 36 dBm (EIRP)
02030311-07 Airspan Networks Inc. 6-11
Installing the BSR Hardware Installation Guide
The following lists the BSR-to-third party antenna cable setup:
Cable (third party): RF coaxial
Connector (third party): N-type male (two N-type connectors for BSR model
for 900 MHz band. The N-type socket labeled Primary is used only if one
antenna is connected. If you are using two antennas for diversity coverage,
attach the second antenna to the other N-type socket.)
Warnings:
1) Before connecting the external antenna, ensure that the BSR is NOT
connected to the power source.
2) Before powering on the BSR, ensure that some type of equipment such as
an antenna or an RF attenuator is connected to the N-type socket. This
eliminates the risk of damaging the BSR device.
6-12 Airspan Networks Inc. 02030311-07
Hardware Installation Guide Installing the BSR
To connect the BSR to a thrid-party external antenna:
Attach the third-party N-type male connector, at the end of the RF cable, to the
N-type socket located on the BSR’s front panel, as displayed in Figure 6-10.
Notes:
1) For crimping cables for N-type connectors, see Appendix B, “Cable
Crimping”.
2) Ensure that the third-party antenna cable is of sufficient quality to reduce or
eliminate loss when operating in the required frequency band.

6.4. Cabling for Serial Configuration
The BSR provides an RS-232 port for serial interface to a PC. This serial interface
allows you to perform local BSR configuration.
Notes:
1) For serial configuration, the BSR must remain connected to the BSDU/SDA
(i.e., the BSR’s 15-pin D-type port remains connected to the BSDU’s/SDA’s 15-
pin D-type port).
2) For a detailed explanation on performing BSR initial configuration, refer to
WipConfig User’s Guide or WipConfig PDA User’s Guide.
