Abstract
A system and method for operating a communications system network, the method including operating an access point (AP) acting as a network controller in a frequency hopping network, the AP communicating with other communication devices of the network over m number of frequencies using a hopping sequence of at least some of the m number of frequencies and a dwell time d for the plurality of frequencies; and operating a communication device seeking to establish synchronized communication with other communication devices of the frequency hopping network without any cross-AP coordination, the communication device scanning all of the m number of frequencies using a scanning time s for each of the m number of frequencies; and, wherein the scanning time s is no greater than 1/m of the AP dwell time d.
