Abstract
Various techniques for reducing power in a wireless network device are disclosed. In some embodiments, software routines within the device are modified to minimize the time during which the analog circuitry in a radio is powered. In some embodiments, the techniques make use of knowledge of implied delays associated with a particular network protocol. For example, in a CSMA network, there is a defined minimum period before the device can attempt to gain access to the media. The radio may be powered off during this defined period. In other embodiments, modifications to a protocol are disclosed which allow additional power savings.
