Installing the SPR
This chapter describes the installation of the WipLL Subscriber Premises Radio
(SPR), located at the subscriber's premises.
Warning: Cables with exposed ends (i.e., not yet crimped) should be covered
with protective polythene bags during external cable installation processes.
Warning: As the system emits microwave radiation, a minimum distance o
f
200 mm must be maintained from the front of the SPR.
Warning: To avoid electrical or fire hazard, connect the SPR to the powe
r
supply only after mounting the SPR and connecting data cables.
Note: Usually, the SPR is initialized (i.e., configured with an IP address) at
Airspan's factory. However, if the SPR has not been configured, see Section
10.5, “Connecting to a PC for Serial Configuration”, before mounting the SPR.

Note: 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
Note: A minimum separation of 200 mm should exist between power and data
cables.

Attaching the mounting bracket to the SPR’s mounting holes.
Attaching the mounting bracket (attached to the SPR) to the wall.
To mount the SPR on a wall:
1. Position the mounting bracket on the mounting surface (e.g., 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.
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 tighten.
The figure below displays relevant dimensions of the mounting bracket. Note the
two different sized fixing holes.

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 SPR and load that may be induced in windy
conditions.
6. Adjust the horizontal positioning of the SPR, and then tighten the two stainless-
steel bolts.
Rotation is restricted to the horizontal plane only. The permissible rotation is
shown in Figure 10-8.

10.2.4. Aligning Using the RSS LED Adapter
You can align the SPR (or third-party antenna) using Airspan's RSS LED Adapter
once the SPR has established a wireless link with the BSR.
The RSS LED Adapter indicates the received signal strength (RSS) between the
SPR and the BSR. This allows you to accurately position the SPR during installation
for optimal radio frequency signal reception.
The RSS LED adapter connects between the SPR and SDA by a CAT 5 cable. The
RSS LED adapter provides two 15-pin D-type ports: one for the SPR side, and the
other for the SDA side.
The following table lists the RSS LED Plug adapter dimensions:
Table 10-2: RSS LED adapter dimensions
Parameter Dimensions
Height 123 mm (4.84 inches)
Width 68 mm (2.68 inches)
Depth 30 mm (1.18 inches)
Weight 85g
The RSS LED adapter can be connected in one of the following manners:
One end connects directly to the SPR’s 15-pin D-type port, while the other end
connects to the SDA through a CAT 5 cable.
Both ends (i.e., 15-pin D-type ports) connect to the SPR and SDA through a
CAT 5 cable.

10.3. Connecting External Third-Party Antenna
(Optional)
The SPR model with an N-type connector can be connected to an external antenna.
The addition of an external antenna allows greater RF sector coverage than the
standard SPR internal antenna models (i.e., 60°).
Cable: RF coaxial
Connector: N-type male
Warning: Before connecting the external antenna, ensure that the SPR is
NOT connected to the power source.
Warning: Before powering on the SPR, ensure that some type of equipment
such as an antenna or an RF attenuator is connected to the N-type receptacle.
This eliminates the risk of burning the SPR device.
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 (or
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: In accordance with FCC regulations, ensure that for external
antennas, the maximum EIRP is 36 dBm. The EIRP is defined as:
Max. Power Output + Antenna Gain + Cable Loss ≤ 36 dBm (EIRP)
Installing the SPR Hardware Installation Guide
10-20 Airspan Networks Inc. 02030311-07
To connect the SPR to an external antenna:
Attach an N-type male connector of the third-party antenna to the N-type
receptacle located on the SPR’s front panel.

10.4. Connecting to the SDA
The SPR’s power supply and connectivity to the subscriber’s Ethernet network is
provided by the SDA. To connect the SPR to the SDA, you need to connect the
SPR’s 15-pin D-type port to the SDA’s 15-pin D-type port using a CAT-5 cable.
The SPR-to-SDA cable setup is as follows:
Cable: straight-through 10Base-T Ethernet UTP 4 Pair CAT-5e 24 AWG
outdoor type (100 meters)
Connectors:
SPR side: 15-pin D-type male (only 8 pins are used)
SDA side: 15-pin D-type male (only 8 pins are used)
Note: Airspan supplies unterminated CAT-5e cables. For a detailed
description on crimping cables, see Appendix B, “Cable Crimping".

Notes:
1) Pins 9 through 15 of the 15-pin D-type connector are not used.
2) The wire color-coding described in the table is WipLL's standard for wire
color-coding. However, if you implement your company's wire color-coding
scheme, ensure that the wires are paired and twisted according to the pin
functions listed in Table 10-4 (e.g., Rx+ with Rx-).
WipLL uses the following wire color-coding standard for CAT 5 cables (8 wires
used) connecting the outdoor radio units to the indoor Ethernet hubs or switches:
Figure 10-15: WipLL wire color-coding for 15-pin D-type connectors
Hardware Installation Guide Installing the SPR
02030311-07 Airspan Networks Inc. 10-23
Warning: To avoid electrical shock, before connecting the SPR to the SDA,
ensure that the SDA is not connected to the power supply.
Notes:
1) The wires are twisted together in pairs, for example, blue/white with blue,
and orange/white with orange. This prevents electrical interference between
the transmitter pins. For example, pin 3 (Tx+; orange / white) is paired and
twisted with pin 4 (Tx-; orange).
2) The SDA connector pinouts are the same for all SDA models (SDA-1, SDA-
4H, SDA-4S, SDA-4S/VL, SDA-4S/Vltag, SDA-4S/1H3L, and SDA-
4S/VL/1H3L).
To connect the SPR to the SDA (see Figure 10-16):
1. Connect the 15-pin D-type connector, at one end of the CAT 5 cable, to the
SPR’s 15-pin D-type port labeled DATA POWER SYNC.
2. Connect the 15-pin D-type connector, at the other end of the CAT 5 cable, to the
SDA’s 15-pin D-type port.

10.5. Connecting to a PC for Serial
Configuration
To configure an SPR, you need to connect a PC running the WipLL WipConfig
configuration tool to the SPR. The SPR’s 15-pin D-type port also provides serial
interface to a PC for SPR initial configuration. This port uses 9 of its 15 pins for
serial interface; the remaining pins are used for interfacing with the SDA with which
the SPR remains connected. To connect the SPR to the management station (i.e.,
PC) and the SDA, a Y-cable (splitter) is used.
Note: SPR configuration is performed while the SPR is connected to the SDA.
The SPR-to-PC and SDA cable connections for SPR serial configuration are as
follows:
Connectors:
SPR side: 15-pin D-type male (only 9-pins used)
PC side: 9-pin D-type (RS-232)
SDA side: 15-pin D-type male

10.6. Connecting Power
The SPR receives power through its 15-pin D-type port from the SDA. In turn, the
SDA connects to an external AC-DC power adapter from where it receives power.
The SDA provides 48 VDC nominal power to the SPR (minimum of 30 VDC:
maximum of 55 VDC).
Warning: If you are using an external antenna, ensure that you connect the
antenna before connecting the SPR to the power source.
Note: For a description on connecting power to the SPR and SDA, see
Chapter 9, “Installing the SDA”.
