Abstract
The present invention reduces inter-network interference between simultaneously-operating closely situated short-range wireless networks. The system provides a central controller that, in addition to eliminating frequencies with known outside interference, may divide an available frequency range into groups of sub-bands that are assigned to the various wireless networks. The wireless communication modules controlling these networks operate only within these assigned sub-bands, and therefore are prevented from conflicting with each other.
