Multiple density configurations and algorithms for intelligent power savings infrastructure in wireless LANS
First Claim
1. A system, comprising:
- a controller; and
a first access point, the first access point comprising;
processing logic; and
at least one wireless transceiver in communication with the processing logic, wherein the wireless transceiver is configured to send data to, and receive data from, client devices;
wherein the processing logic is configured to;
determine a number of the client devices associated to the first access point, andtransmit the number to the controller; and
wherein the controller is configured to;
determine that at least one client device is associated with the first access point;
determine that the at least one client device is capable of associating with a second access point;
force the at least one client device to roam to the second access point; and
transmit a signal to the first access point to switch to a power save mode,wherein at least one of the processing logic and the at least one wireless transceiver is configured to switch to the power save mode responsive to receiving the signal from the controller, wherein the signal represents a determination that no client device is associated with the first access point.

Abstract
Described in example embodiments herein are techniques for implementing power savings in a wireless local area network (WLAN). In accordance with an example embodiment, a centralized controller can be employed to gather data about network activity and select access points to switch to power save mode. Optionally, the controller may designate certain access points to remain active so as to monitor for clients attempting to access the WLAN. An aspect of an example embodiment is that it allows the controller to configure and manage power consumption based on demands on the overall system. In an example embodiment, techniques for implementing power savings within individual hardware components, such as access points, are disclosed. An aspect of a technique described in an example embodiment is that it provides flexibility to balance power savings and performance.
