Abstract
A wireless communication system includes a first access point managing a first wireless local area network and at least one second access point managing at least one respective wireless local area network. A CSMA/CA procedure is employed. The first access point is involved in a real-time sensitive transmission. Each access point implements an energy detection mechanism and a preamble detection mechanism in the context of the CSMA/CA procedure. The energy detection mechanism is implemented for accessing the primary channel and for accessing each secondary channel. The preamble detection mechanism is implemented for accessing the primary channel and optionally for accessing each secondary channel. A decision making unit instructs the first access point and each second access point to use the same primary communication channel. This improves the conditions under which the real-time sensitive transmission takes place.
