摘要： 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.

摘要： In one embodiment, a signal detector is coupled to an external power source. The signal detector is configured to ascertain whether a predetermined signal was received from the external power source. Control logic is coupled to the signal detector and to the external power source. The control logic is responsive to the signal detector to determine a characteristic of the external power source based on whether the signal detector detected the predetermined signal. The characteristics of the external power supply can be determined based on the frequency, amplitude and duration of a signal received from the power injector. This enables the control logic to determine the power available from an unknown power supply and to configure a device to operate accordingly.

摘要： A switching interface comprising a switch having an input and a plurality of outputs, and a memory associated with the switch. The switch is adapted to receive a packet from the input, the packet to be forwarded to a destination device coupled to a one of the plurality of outputs. The switch is responsive to store the packet in the associated memory. The switch is further responsive to a signal from the destination device to forward the packet from the associated memory to the destination device through the one of the plurality of outputs. Optionally, the switching interface may further comprise a packet encryption engine coupled between the input and the associated memory. Typically, the output devices coupled to the plurality of outputs will each have its own separate encryption process; in these scenarios the encryption engine will have logic for determining the appropriate encryption for the output device.

摘要： A system and method for increasing accuracy of transmitter power detection over a larger range of output power levels wherein a diode detector is followed by a series cascade of 2 op amps. The first op amp functions as a differential/buffer amplifier, which improves temperature performance. The second op amp has two selectable gain factors. The output of the second op amp is routed to the ADC. A single control line is connected to a controllable switching device that configures the second op amp for high gain or low gain.
