Airselect实际上是自动跳频技术,UBNT引入这一技术的目的是为了在干扰比较大的环境中让设备自动去寻找最佳的工作频率,获得最佳的传输效果。
有关这一技术的英文原文引述如下:

AirSelect
AirSelect is a technology that dynamically changes the wireless channel used, in order to avoid interference and increase throughput, by hopping to the channel least used in the Frequency List (user defined) periodically within a user-defined time interval (in Milliseconds).
Enable AirSelect: if enabled, the device will use the AirSelect feature. This feature will help inexperienced installers, i.e. those without RF knowledge; or devices used in highly dynamical environments. However, it still requires good RF planning.
Frequency List: defines the channels within which AirSelect will hop to find the one less crowded.
Hop Interval: defines the time interval between each hop, expressed in milliseconds. The default value is 3000 milliseconds.
Announce Count: this is the number of times between hops the AP will announce to the clients the next hop information (frequency, etc). For instance, if hop interval is set to 10000 milliseconds, and announce count is set to 10, every 1000ms the AP will send an announcement to the clients with upcoming hop information. The larger this period is, the higher risk of timing drift (hops not being synchronized), so it is recommended to keep this hop announcement to every 100ms (or Announce Count to 1/100th of Hop Interval).
