• Hello,

    This question may not be directly related to CWTS. But want to know exact feature of cisco clear air technology. Just want to know in brief about the concept of this. Typically in 802.11N, we get 3 or 4 antennas, MIMO technology etc which is better than 802.11b\g\a. So is clear air something more than this.

    Hello Temkar


    Cisco's clean air technology is essentially a spectrum analyser chip inside the AP. It examines the RF environment and enables the AP to make channel selection decisions based on what it sees. Thats it in a nut shell. It works alongside your 802.11a/b/g/n technology.



  • The separate chip for the Spectrum analysis is most of the key to the technology.   Previously, and in other vendors gear, the same chip as the Wi-Fi connection was used to test the RF environment.
    Separately, they can both do their job, and with only a small amount of coordination they do not interfere or slow down the function of the other.
