Using multiple channels over single channel the performance can be significantly increased since the use of multiple channels can reduce interference influence. Channel assignment is one of the most basic and major concern in such networks. By effectively utilizing multiple non overlapping channels and multiple interfaces, collision and co-channel interference can be reduced. This allows more concurrent transmissions and thus enhances the network capacity. In this technique an interface is allowed to dynamically change its working mode between send and receive on a call-by-call basis, which enhances the utilization of both interface and channel.
