20110051700 | MODIFYING SYSTEM CLOCKS BASED ON PARTICULAR WLAN CHANNEL THAT IS SELECTED TO IMPROVE RF SENSITIVITY OF A RADIO MODULE - Techniques are provided for selecting one of a plurality of clock signals used to drive a bus of a WLAN-enabled device having a WLAN radio module coupled to the bus and designed to operate over a plurality of WLAN channels. A network infrastructure device, such as an access point or port, is provided that comprises a WLAN radio module, a PCI bus coupled to the WLAN radio module, a look up table (LUT) and a processor. The WLAN radio module designed to operate over a plurality of WLAN channels in a first frequency band. The LUT comprises a plurality of entries. Each entry comprises: a particular one of the WLAN channels and a corresponding one of a first clock signal having a first clock frequency and a second clock signal having a second clock frequency that is to be selected. The first clock signal causes interference at the WLAN radio module when operating over a first subset of the WLAN channels, and the second clock signal causes interference at the WLAN radio module when operating over a second subset of the WLAN channels. The processor selects, from the LUT based on the one of the WLAN channels that has been selected for the WLAN radio module to communicate over, either the first clock signal or the second clock signal that is to be used to drive the bus. | 03-03-2011 |

20090222576 | METHOD AND APPARATUS FOR REDUCING POWER CONSUMPTION OF A NETWORK COMMUNICATION DEVICE RECEIVING STREAMING CONTENT VIA AN IP-BASED NETWORK - A method and apparatus for transmitting multimedia content to a network communication device, such as a wireless local area network (WLAN) device, via one or more IP-based networks, in a manner that reduces power consumption by the network communication device. A system stream server, such as a set-top box, transmits content using a burst transmission mode. The transmitted content includes control information indicating the time of the next transmission burst, thus allowing the device to go into a sleep mode when the content stream is not being burst. Operation of the device in this manner reduces power consumption by the device. The stream server can switch dynamically between burst and non-burst transmission modes according to the needs of the network communication device. The IP-based network is bi-directional, thus the network communication device can communicate to the stream server the manner in which transmission bursts can be received by the device. | 09-03-2009 |
