6.4.2 Installing RAUs
CAUTION: Install RAUs in indoor locations only. Do not connect
an antenna that is installed in an outdoor location to an RAU.
Installing RAUs
Mount all RAUs in the locations marked on the floor plans.
Considerations:
• Install iDEN and 800 MHz cellular RAUs so that their antennas will be at
least 6 to 8 meters (20 to 26 feet) apart. Separation is required to reduce signal
interference between the two frequency bands.
• Attach the RAU securely to a stationary object (i.e., wall, pole, ceiling tile).
• For proper ventilation:
• Keep at least
76 mm (3 in.) clearance around the RAU to ensure proper venting.
Do not stack RAUs on top of each other.
• Always mount the RAU with the unpainted face against the mounting surface.
Installing Passive Antennas
Refer to the manufacturer’s installation instructions to install passive antennas.
Passive antennas are usually installed below the ceiling. If they are installed above
the ceiling, the additional loss due to the ceiling material must be considered when
estimating the antenna coverage area.
Considerations:
• Install iDEN and 800 MHz cellular RAUs so that their antennas will be at
least 6 to 8 meters (20 to 26 feet) apart. Separation is required to reduce signal
interference between the two frequency bands.
Connecting the Antenna to the RAU
Connect a passive antenna to the SMA male connector on the RAU using coaxial
cable with the least amount of loss possible.
CAUTION: Firmly hand-tighten the SMA female connector –
DO NOT over-tighten the connector.
