Sorry if this questions is fool, but I visited an Hotel because they have isssues with its wireless network, they have four Wavions antennas, but they're working on channels 3,9,10. This antennas give service to rooms, beach, lobbies etc. In some places like restaurants they have AP's ubiquiti working in channels 1,6,11.
The wavion Antennas work on 2.4 band. I think the wavion are using incorrect channels, because I know 2.4 band just can use channel 1,6,11.
