Abstract
An apparatus and methods are provided for sharing cell coverage information among devices in a cell network. Cell coverage information includes bitmap models of signal strength to enable intelligent handover decisions. Mobile terminals are able to receive cell coverage information over a broadband unidirectional broadcast network, such as a digital video broadcast network. They are also able to receive cell coverage information from other mobile terminals via ad hoc wireless signalling. Mobile terminals are also able to store and upload raw signal measurements to a cell coverage information center.
