Title: POWER MANAGEMENT BY POWERING OFF UNNECESSARY RADIOS AUTOMATICALLY
Abstract:
A system and method are provided for automatically shutting off or reducing power to certain radios in a client device based on collected wireless network quality parameters. The wireless network quality parameters are collected from wireless networks by various client devices in communication with the wireless networks. The client devices report the wireless network quality parameters to a server. The server collects wireless network quality parameters from a plurality of client devices and analyses the wireless network quality parameters from the plurality of client devices to determine a network quality for the particular wireless networks. The network quality is stored in a network quality database maintained by the server. When it is determined that a device is in an area of weak signal coverage, power to its radio is automatically reduced or shut off until the device leaves the area.
