Abstract:
1. A method for reducing an average time needed for a communication unit to connect to a communication network, wherein said communication unit has to listen for data transmissions on a plurality of communication channels and to identify one of said plurality of communication channels, on which an ongoing data transmission is detected, before being able to begin transmitting, the method comprising: monitoring a time lapsed since last data transmission on said one of said plurality of communication channels was ended, and provided that a condition of low data traffic is detected corresponding to that no further data transmission on said one of said plurality of communication channels occurs during a given period of time since said last data transmission on said channel was ended, transmitting data on said channel in order to enable said communication unit to detect said ongoing data transmission, wherein beacon frames are sent on said one of said plurality of communication channels at regular time intervals, and said given period of time is shorter than said regular time intervals.
