Interference with multiple SSID on same antenna ???????

alex_cordova — Mon, 21 Jul 2014 18:33:53 GMT

i have 1AP with 6 SSID.. it means 6 RF signal ??
therefore, it means AP causes his own interference ??
its similar to have 6 antenas on same place radiating with same

channel and power.???
devices( as a laptop) receive 6 signals and therefore

interference wich comes from one antena????

regards......!!!!!

Your AP may have two radio/antenna combinations, in 2.4G and 5G radio bands. You can advertise up to 8 SSIDs on each radio, but less than 5 is recommended.

The APs do not interfere with themselves, but use time division multiplexing
methods to share the bandwidth among the wireless clients using your SSIDs.

better understanding.

Hi,
6 SSID means, 6times beacon packet generated in each radio chip set.
So it's not the issue of interference, it have 6 times more congestion issue compare to only one SSID running
Thanks

That's not entirely accurate either. Each SSID results in a slight additional overhead because there are certain management frames (like beacons or broadcast/multicast traffic) that must be done per SSID. But unless you have an extremely dense network, it is probably not an effect you will notice. Bottom line, you can run 6 SSIDs on low to medium density networks without much concern, and it is not like putting 6 Ap's right next to each other.
