Granted: 2013-12-10
Abstract: The overlapping spectrum cellular communication network functions to provide multiple cellular communication systems in the same spectrum as the existing NATS-based cellular communication system, while also providing wideband services to subscribers. This is accomplished by enabling two system operators to each have a dedicated 1.25 MHz slice of the NATS spectrum. However, given that there is only 2 MHz available, this results in a 0.50 MHz overlap of 1.25 MHz carriers. To mitigate the inter-network overlap and the potential for interference between the two systems, the overlapping spectrum cellular communication network swaps forward and reverse path allocations on a per system basis.
