  • Patent number: 10439655
    Abstract: An example may include access point, comprising: a processing resource; a first radio transceiver; a first radio frequency (RF) sub-band filter on the first radio transceiver; a second radio transceiver; a second RF sub-band filter, complementary to the first RF sub-band filter, on the second radio transceiver; and instructions executable by the processing resource to enable and disable the first RF sub-band filter and the second RF sub-band filter based on a network metric.
    Type: Grant

  • Patent number: 8971443
    Abstract: Techniques are presented to reduce the number of antennas used for a transmission for a given antenna configuration and data rate. At a wireless communication device having a plurality of antennas and capable of sending a transmission via one or more of the plurality of antennas, a determination is made of a data rate and antenna configuration to be used for a transmission. A comparison is made between a total transmit power for a minimum number of antennas for the data rate to be used for the transmission and a total transmit power associated with the antenna configuration for the transmission. When the total transmit power for a minimum number of antennas for the data rate is greater than the total transmit power associated with the antenna configuration for the transmission, the transmission is sent with the minimum number of antennas.

  • Patent number: 7184722
    Abstract: A system and method for transmitting data communications through air using a radio. The invention allows the user to select from a number of predetermined output transmission powers. When a lower output transmission power is selected the current drain to the associated amplifier is decreased thereby conserving battery power of the radio. In addition, a detector diode circuit combined with an adjustable gain amplifier combine to provide a feedback mechanism whereby the output transmission power of the radio is held substantially constant over a broad range of temperatures.

  • Publication number: 20060092889
    Abstract: A method for controlling cell size associated with an access point that has a receive sensitivity and an output power. The method includes changing a start of packet threshold and/or a clear channel assessment threshold to vary the cell size of the access point.

  • Publication number: 20060035394
    Abstract: The present invention provides a method for manufacturing semiconductor devices, a method for manufacturing an integrated circuit, and a method for improving a drive current for semiconductor devices on a wafer-by-wafer basis. The method for manufacturing semiconductor devices, among other elements, includes patterning gate structures on a substrate (220), each of the gate structures having a profile associated therewith, and obtaining information representative of the profiles of the gate structures (240). In accordance with the present invention the information may then be fed forward to alter a manufacturing parameter associated with a drive current of the semiconductor devices (250).

  • Publication number: 20050245088
    Abstract: A method for determining the anti-reflective coating (or bottom anti-reflective coating) over-etch time adjust with real-time process feedback is presented. The critical dimension CDresist of the patterned photoresist is measured and a first wafer with median values chosen (101) from a lot. A first time t* is found (102) and used to form the desired structure. Using the measured critical dimension of the formed structure on the first wafer a second time tlot is found (104). Finally, an over-etch time t(x) is found and used to etch the remaining wafers in the lot (106).
