Abstract
A method and system for overriding Carrier-Sense-Multiple-Access/Collision-Avoidance (CSMA/CA) without harming the traffic that occupies the channel are provided. The system and method may include for example detecting at a communication node having a plurality of antennas, a preamble transmitted by a co-channel neighboring node operating in compliance with IEEE 802.11 standard within a clear channel assessment (CCA) range of the communication node; and setting uplink transmit weights of the antennas of the communication node, to isolate the communication node from the neighboring node after the neighboring node has transmitted the preamble, to allow the communication node to access the co-channel, by keeping a transmitted signal level of the communication node as received by the neighboring node, below the CCA signal level at one or more of the antennas of said neighboring node. The system may for example implement the method in software running on a baseband processor.
