A. When adding AP joint points on the original indoor sub-system, if the original system has power amplifier equipment, the AP joint position should be selected behind the power amplifier device.

B. For a distributed deployment design with the same environment layout on each floor, a uniform and symmetrical antenna feeder design can be selected. For example, the combined location of each floor, the number of APs, the number of couplers and power splitters, and the device specifications can all be unified

C. Under normal circumstances, there cannot be more than 1 WLAN signal on the main path of the combined system, which will cause mutual interference of WLAN signals and fail to demodulate.

D. There are two ways to expand the capacity of the combined system. One is to modify the antenna at the end of the system, insert a combiner, and add APs; the other is to use a dedicated WLAN dual AP combiner
