Abstract:
1. A method of operating a wireless control system, the method comprising: receiving measurements that indicate channel performance information and round trip delay information for a plurality of wireless communication devices operating within a first frequency band of a multi-band wireless network; processing the channel performance information and the round trip delay information to determine a probability of successful transfer from the first frequency band of the multi-band wireless network to a second frequency band of the multi-band wireless network for each of the plurality of wireless communication devices by at least normalizing a maximum ratio of effect energy to total energy and noise (Ec/Io) and a minimum round trip delay and calculating a weighted sum of the normalized maximum Ec/Io and the normalized minimum round trip delay for each of the plurality of wireless communication devices; identifying a subset of the plurality of wireless communication devices with probabilities of successful transfer that exceed a transfer threshold; removing from the subset of the plurality of wireless communication devices those wireless communication devices whose velocity exceeds a movement threshold resulting in a modified subset; receiving loading information for the first frequency band of the multi-band wireless network and processing the loading information to determine if the loading information exceeds an offload threshold; and if the loading information exceeds the offload threshold, then identifying a first wireless communication device from the modified subset of the plurality of wireless communication devices and transferring an instruction to modify an operating frequency of the first wireless communication device from the first frequency band to the second frequency band.
