What problems may exist for a multiple channel architecture (MCA) WLAN when its APs are...

Wi-Fi enabled voice handsets with low transmit power can experience asynchronous downlink and uplink performance.

WLAN client stations can experience the hidden node problem when located near each other within the same cell.

The mismatched power between WLAN client stations and APs violates regulatory and IEEE signal quality requirements.

Cell size may be too large, causing co-channel interference to adjacent cells and reducing system capacity.

APs operating in the 2.4 GHz band would prevent microwave ovens and analog video cameras from functioning.
