AP 3500

Heelo Folks

does the cisco new wireless AP 3500 stops the Interference,,we have unified wireless network

2)is it applicable is that  user run over channel 1 while 2nd user run over channel 6  and user 3 run on channel 11 on the same access Point?

interference cannot be stoped..

Therefore no..

2) no, the radio interface can only work at one frequency at the same time, so you can only have clients connected at the same time in the same channel this is why yhis is known as shared medium.

Can u clarify More?

let see if i understood ur reply,so every AP ruuning in 1 channel,so if u have 5 APs ,then each will oprate on independant channel .i mean AP-1 run in channel 1 AP-2 run on channel 2 AP-3 Run on channel 3,am i right

Interference is everything that avoid the communication so, for example, any other device working on the same frequency at the same time will be noise to each other, for example cordless phones that works at 2.4ghz bluetooth devices and many other things....  so you cannot stop interference at all.

2) Yes, however that is why it is recommended to use non-overlapping channels..  1, 6, 11 for America

So if you want to avoid interference between APs, use those, use this graphic as example:

Hi Ibrahim,

As already mentioned the 3500 does not correct interference. But what it does do is tell you its there.

Your access points (if they do 802.11g and 802.11a/n) have 2 radios. Just like a CB or a remote control car. You client and your ap have to be on the same frequency. So your access point, if on channel 1 is on freq 2412. Well your clients in order to talk to the AP need to be on the same channel 1, 2412.

Since you have 1 802.11g radio. You only have 1 channel. For example 1.

As mentioned by Dman you want to insure you have 22 MHz spacing between channels. This is why your APs channels should be 1,6,11.

Make sense?
