Abstract: In a wireless local are network, each of multiple access points, in a high density deployment, are configured to suppress co-channel interference. A first access point having a plurality of antennas beamforms a transmission to a wireless client device within a null-space or with the weakest singular eigenmodes of a wireless channel between the first access point and at least one co-channel second access point. Techniques are presented herein for situations in which any given access point has two or more co-channel access points. In addition, an access point may perform receive side suppression with respect to a transmission (made by a co-channel access point to one of its associated wireless client devices) that is received from that co-channel access point.

Abstract: Techniques are provided to de-correlate sub-bands of a packet to be transmitted. At a communication device, a signal (packet or frame) is generated for transmission. The packet or frame comprises a plurality of subcarriers in each of a plurality of sub-bands. Different cyclic delays are applied to the plurality of sub-bands of the signal. The signal is amplified after applying the different cyclic delays for transmission from the communication device.

Abstract: In an example embodiment, there is disclosed an apparatus comprising a first transmitter, a second transmitter, and logic coupled to the first transmitter and the second transmitter. The logic is operable to limit a time period the second transmitter is able to transmit while the first transmitter is transmitting.

Abstract: The present invention is directed to a power detection circuit for use in a wireless transmitting device. The circuit makes use of multiple gain paths so that two or more scaling factors are provided. Each scaling factor allows the detector circuit to provide more ADC levels per dB and thus provide accurate power control over a wider power range than through the use of a single gain path and a single scaling factor.

Abstract: A method to adjust either the detection sensitivity threshold (e.g., the clear channel assessment (CCA) for an 802.11 complaint wireless transceiver) and/or the receiver communication sensitivity threshold (e.g., the start of packet (SOP) for an 802.11 complaint wireless transceiver) to improve performance in a wireless networking environment, such as a high density environment. Both the detection cell and the communication cell can be set equal to each other or the detection cell and communication cell can be independently set. There are also described herein techniques for determining detection cell. Also described herein are techniques for determining communication cell. The present invention includes apparatuses configured to implement a method and/or technique described herein.
