CAUTION: Install RAUs in indoor locations only. Do not con-
nect an antenna that is installed in an outdoor location to an RAU. 
For outdoor installations, a protective enclosure is required.

Mount all RAUs in the locations marked on the floor plans.

• You can place the unit, without its fastening hardware, on a flat surface, such as a 

shelf, desk, cabinet, or any other horizontal surface that allows stable placement 
with the mounting base facing down to the mounting surface. For mounting to 
other locations (that is, walls, ceilings, poles) the RAU must be securely mounted 
using the 4 slotted mounting holes provided with #6 diameter fasteners. This 
method of mounting must securely hold a minimum of 7 lbs. load.

• Attach the RAU securely to a stationary object (that is, a wall, pole, or 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 solid face (containing the mounting holes) 

against the mounting surface.

• For the 800/850/1900 MHz RAU (P/N: FSN-W2-808519-1), make sure the 800 

MHz iDEN antenna and the 850/1900 MHz antenna are separated by enough space 
to reduce signal interference between the 800 and 850 MHz bands. Refer to 
“800/850 MHz Isolation Requirements” on page 7-33 for the recommended dis-
tance between 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, you must consider the additional loss due to the ceiling material when 
estimating the antenna coverage area.
