3.5.1 Location
RFU placement is determined by first choosing an approximate location for each
RFU using basic coverage requirements, then identifying the mounting
configuration for each RFU (ceiling or wall). The number of RFUs is determined
by dividing an area’s square footage by the minimum RFU coverage area,
(32,000’). Typically, a floor plan of each story in the building is used as an aid to
identify RFU placement.
