WLAN bridges only work in the 2.4 GHz frequency band and they support only SISO communications

WLAN bridges must use a channel with acceptable SNR at both transceivers to maintain the desired data rate bi-directionally

WLAN bridges may support MIMO communications, but only if used in the 5 GHz frequency band

WLAN bridges must be implemented such that no interference occurs on the channel anywhere between the two endpoints used to establish the bridge
