Abstract:

With the development of WLAN scale and users number,the energy consumption of the idle AP has become increasingly prominent.In order to solve the problem of idle AP power consumption,two kinds of mature dynamic radio management technologies,AP equipment shutdown and AP RF channel shutdown,were in-depth studied,and their principles and implementation effects were put forward.It's proved that both of the dynamic radio management technologies have the advantages of energy saving,1ow complexity,1ow cost and easy contro1,providing technology support for the construction of green energy-efficient network.

Key words: WLAN, access point, energy saving, radio frequency, timing, shutdown
