Abstract:
A cellular communication device having improved channel-scanning, comprising:a receiver receiving informational content carrying communication signals over a plurality of different frequency carder reception channels respectively associated with a plurality of different base station transmitters, said receiver including a processor; a demodulating and decoding circuit operative to convert the received communication signals of a selected one of the different frequency carrier reception channels to an indication of informational content carried by the communication signals of the selected one of the different frequency reception channels; and a wideband digitizing circuit responsive to said processor and operative to intermittently monitor the plurality of different frequency carrier reception channels for carrier frequency signal strength contemporaneously with receiving of the informational content carrying communication signals by the receiver, the wideband digitizing circuit being incapable of converting the plurality of different frequency carrier reception channels to an indication of informational content.
