Power savings in a wireless digital network. In a network having a plurality of access nodes attached to a controller, access nodes are placed in reduced power states depending on network use or time. In a first embodiment, portions of an access node may be switched between normal and low power modes based on access node activity, or on command. In a second embodiment, the entire access node may be placed in a lower power mode, and awakened from this lower power mode by a LAN signal. A power manager monitors wireless network use to determine which access nodes connected to a controller are to be placed in a low power state. Calendar and time scheduling may also be used. |
