Abstract
A multiple-layered cellular communication system particularly adapted to mobile phones and LAN type communication is provided with an overlaid arrangement of cell transceivers. By having this overlay, multiple service providers can provide a cooperative method of load sharing. The usage of the frequency spectrum can be improved and an advanced hand-off arrangement can be used to prevent or reduce the possibility of blocked calls due to cell saturation.
