In addition, RFU placement requires taking into consideration such factors as
interior structures, multiple-floor installations, elevators and stairwells, and
neighboring macro cell systems. For more information, refer to the RFN
document, RF Planning Guide for RadioFrame Systems (990-1001-00).

3.5.2 Mounting
Once the approximate RFU locations have been identified, determine the
mounting configuration required for each RFU—on or above the ceiling, or on a
wall. Wall mounts are ideal, provided the wall is of low density. Mounting the RFU
to a structural brick or concrete wall can alter the unit’s omni directional pattern.
Also, each RadioBlade installed in an RFU is supplied with an antenna designed
to be installed vertically and pointed down. Do not change this orientation.

Suspended ceilings are very common in commercial buildings and mounting the
RFU above the ceiling can work well, provided lower half of the RFU is kept clear
of metal objects such as water pipes, wire bundles and light fixtures. The added
benefit of an above-ceiling installation is that the RFU is hidden yet still easily
accessed. Generally, suspended ceiling panels are of low-density lightweight
materials that do not attenuate RF. The metal grid supports typically are spaced
at greater than 2-foot intervals and will not dramatically affect the RFUs’
performance if they are kept at least 1-foot away from the antennas.
