WIFI性能测试二 --- wifi的ANI功能
最近解决公司wifi产品经常断线和连接不稳定时,查阅了一些资料,现总结记录如下:
1. wifi的ANI功能

Atheros Adaptive Noise Immunity
In the Atheros AR5212 and newer chipsets there is a new feature called Adaptive Noise Immunity. It is basically a hardware noise reduction technology.
Adaptive Noise Immunity (ANI) adjusts various receiver parameters dynamically to minimize interference and noise effect on the signal quality.
I’ve got some 2.4 gear in a noisy neighbor hood and I was just sick to death of the interference. I’ve been tweaking and tweaking when I saw the ANI setting. I figured I would give it a swing and set it to client mode…seconds later when the client reconnected my CCQ went from 12% to 80% and my throughput went up by a factor of about 15!
CLI
/interface wireless set 0 adaptive-noise-immunity=ap-and-client-mode | client-mode | none
Winbox
Modes:
AP and client = Will adjust if acting as AP or client
Client = Will adjust only if acting as client
None = Disabled
Here is Atheros’ patent doc on the technology.
Mikrotik officially says that Nv2 inter operates with ANI.
I would say that if you have some noisy areas, then give this a swing and see if you get an improvement.
