2.2.2 Remote 
ACUs 
Remote ACUs are located in Telco rooms or other closets throughout the 
building mounted in 19” EIA-standard compliant racks or equivalent. The racks 
for remote ACUs may be either floor or wall-mounted racks. Any other method 
used to mount the remote ACU is not approved, and could void the warranty on 
the product and other components in the RFS. 
2.2.3 RFUs 
RFUs are located throughout the building to provide coverage for specific areas. 
RFUs are typically mounted on or above the ceiling, or on a wall. The following 
illustration depicts typical RFU locations using a simple floor plan. Three RFUs, 
denoted by triangles, are located along the central hallway providing coverage to 
each portion of the floor. Antenna coverage for each RFU is a 100-foot radius 
(30.3 meters) or approximately 32,000 square feet (2,920 square meters).

2.2.3.1 
RadioBlades and RAPS 
The number and combination of RadioBlades and RAPs to be installed in each 
RFU is driven by the coverage and capacity requirements of that particular 
portion of the building. A maximum of six iDEN RadioBlades can be installed in 
each RFU. A maximum of three RAPs can be installed in each RFU. The 
combined total of iDEN RBs and RAPs is seven per RFU. Each RadioBlade is 
supplied with an antenna that must be installed vertically and pointed down 
towards the ground.
