Installing the IDR
This chapter describes the installation of the WipLL Indoor Data Radio (IDR),
which is installed at the subscriber site.
Warning: When operating in the 900 MHz band, the IDR model with an
external antenna must not be co-located or operating in conjunction, with any
other antenna or transmitter.
Warning: To avoid electrical or fire hazard, ensure that all cable connections
to the IDR are performed prior to connecting the power supply.
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

12.2. Mounting the IDR
The IDR is installed indoors. It is positioned so that the IDR (or a third-party
external antenna) is in line-of-site with the WipLL Base Station (i.e., BSR).
The IDR may be mounted in the following ways:
Desktop
Pole
Wall
Warning: The IDR must only be installed indoors. Airspan is not liable and
responsible for any damages that may occur to the IDR if it is installed
outdoors.
Note: Before mounting or attaching any brackets to the IDR, ensure that all
cables are securely attached and that the unit functions correctly in the
proposed location.

12.2.2. Wall and Pole Mounting
The IDR may be mounted to a wall or to a 5-cm diameter pole. Wall and pole
mounting both use the same mounting brackets and wall hanger plate.
12.2.2.1. Assembling the Bracket and Hanger Plate
The wall hanger plate secures the IDR to a wall or pole. The wall bracket and hanger
plate allows positioning the IDR in the correct orientation. Holes are provided in the
wall hanger plate for both pole and wall mounting options
To assemble the bracket and hanger plate:
1. Insert a 4 mm hex nut into the slot on the tilt arm component
2. Holding the nut in place, attach the tilt arm to the mounting bracket using a 4
mm socket head bolt. Hand-tighten the bolt only. See Figure 12-4.
3. Affix the complete mounting assembly to the rear of the IDR using the 4-off
self-tapping screws supplied with the kit.

12.2.2.3. Wall Mounting
Warning: Prior to drilling holes in a wall ensure that there are no hidden
services such as electricity cables or water pipes. A stop must be used on the
power drill to ensure that bored holes do not exceed 35 mm.
To mount the IDR on a wall:
1. Loosen the 2-off M4 socket head screws on the mounting bracket tilt-arm and
remove the wall hanger.
2. Offer up the wall hanger to the wall and scribe through the mounting-hole
locations.
3. Drill holes to suit the type of wall fixing.
4. If required insert anchor plugs suited to the wall material.
5. Affix the wall hanger using 4-off screws suited to the anchor plugs and wall
material.
6. Re-attach the IDR mounting bracket to the wall hanger. Finger-tighten the
screws.
7. Position the IDR at the desired inclination.
8. Re-tighten the screws to lock the IDR in position.

12.3. Connecting a Third-Party External
Antenna
The IDR provides a TNC-type connector for connecting a third-party antenna. This
antenna can be placed on the subscriber’s windowsill to provide better RF signal
reception with the BSR.
Connector: TNC-type male
Warning: Before connecting the external antenna, ensure that the IDR is NOT
connected to the power source.
Figure 12-10: Connecting a third-party antenna
Hardware Installation Guide Installing the IDR
02030311-07 Airspan Networks Inc. 12-13
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: Indoor units and antennas should be installed ONLY by experienced
installation professionals who are familiar with the local building and safety
codes and are licensed by the appropriate government authorities
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)
Warning: When using external antennas, the external antennas must not be
co-located or operating in conjunction with any other antenna or transmitter.
12.4. Connecting to an Ethernet Network
The IDR provides one Ethernet interface for the subscriber’s Ethernet network. This
port is located on the front panel, and labeled Ethernet.
The IDR-to-Ethernet network cable set up is as follows:
Cable: CAT-5
Connector: 8-pin RJ-45

12.6. Connecting to PC for Serial Configuration
To perform IDR initial configuration, you need to connect the IDR’s RJ-11 port to
the serial port of a PC running the WipLL network management application (i.e.,
WipConfig).
The IDR’s RJ-11 port labeled Serial, located on the front panel, connects to the
serial port of a PC. This is performed using two cables (straight through and
crossover) and an RJ-11-to-9 pin D-type female adapter on the crossover cable.
Connectors:
6 pin RJ-11 male (to IDR)
6 pin RJ-11 male (to adapter)
6 pin RJ-11-to-9 pin D-type female adapter
9 pin D-type male (to adapter)
9 pin D-type female (to PC)

12.7. Connecting Power
The IDR is powered by an external power supply (Triple Output External Adapter).
The IDR connects to the power adapter via the IDR's power port located on the
IDR’s front panel.
The following table lists the external power supply specifications:
Table 12-4: IDR power supply requirements
Power parameter Units
Voltages 110-240 VAC
Frequency 50 to 60Hz
Maximum power
consumption
Less than 15W
Warning: If you are using an external antenna, ensure that you connect the
antenna before connecting the BSR to the power source.
Warning: Ensure that plugs fitted to mains power leads for subscriber
premises equipment are compatible with AC mains sockets. Do not replace
plugs on power leads to suit local requirements without first verifying earthing
practice for the country and equipment in question.
Careful consideration must be given to issues including local wiring
requirements, cable color-coding, and safety earthing and circuit protection
requirements.
Warning: To avoid electrical or fire hazard, ensure that the data connections
to the IDR are made prior to connecting the power supply. The AC mains must
be capable of supplying at least 230 VAC
Installing the IDR Hardware Installation Guide
12-22 Airspan Networks Inc. 02030311-07
Prior to connecting to the power outlet, the following pre-connection inspection
should be performed on power sockets:
Ensure no other equipment is connected to the power outlet.
Ensure no physical sign of damage to the power outlet.
Ensure no water or dampness on or around the power outlet.
Ensure plug and socket assemblies are firmly secured.
Check the power outlet to verify the earth loop impedance value and the
presence of phase, neutral and earth connections using a proprietary plug tester
such as a ‘Martindale Ze’ type.

To connect the power:
1. Plug the AC power adapter’s 6-pin Molex connector into the IDR’s power port
labeled Power (see Figure 12-14).
2. Plug the AC power plug female, at the one end of the AC power cable, into the
AC power adapter’s socket (see Figure 12-14).
3. Plug the AC power plug male, at the other end of the AC power cable, into the
electrical outlet (see Figure 12-14).
