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.
Abstract: A method for monitoring a wireless network includes, at a device including a communication interface coupling the device to a wireless network, monitoring messages transmitted between the communication interface and the wireless network, and outputting monitoring data associated with the monitored messages from the device.

Abstract: Detecting a signal included receiving a modulated waveform, and processing a first quantized signal generated from the waveform to produce a second quantized signal. The second quantized signal is a representation of the first quantized signal with lower resolution that the first quantized signal. The second quantized signal is correlated with a quantized reference signal.

Abstract: A clock distribution approach includes distributing a clock signal from a clock tree to a first set of circuit elements characterized by a first circuit characteristic; and distributing a clock signal from a sub-tree of the clock tree to a second set of circuit elements characterized by a second circuit characteristic different from the first circuit characteristic.
