I'm upgrading a tower from a single omni to three sector antennas. I understand I need to run the antennas on different frequencies, but should I be running them with the same SSID or different SSIDs? My preference would be to be able to run them with the same SSID so that some subscribers could automatically fail over to one of the other antennas in case of failure, but I suspect that there's a negative to this that I may not be thinking of.
(I know I could have the CPEs seek multiple SSIDs if they were Mikrotiks, but they're older, legacy radios that don't have this capability.)
