DRAFT
4.6.3 Coax Cable Lengths and Losses
Use coax ½”, 50ohm, male-to-male QMA type, for connecting to RAU and external antenna ports.
Note:
The required distance between the antennas (installed in the ceiling) depends on the infrastructure and calculated
path-loss. For example, if there is free space-loss between the antennas, a minimum distance of 100 ft is required; if
there are partitions (loss) between the antennas, a distance of less than 100 ft between them is allowed.
