Problems solved by technology

One problem with such enhanced capabilities is the bandwidth required to transmit the large volume of data associated with such enhanced capabilities from the digital data servers interconnected with the internet to the PCS devices via the direct link.
However, graphical information such as maps and pictures require relatively wide bandwidth to provide reasonable response times. Video and audio files will require even higher bandwidth for reasonable response times. In other words, using the relatively low bandwidth of the current cellular telephone system will require long periods of time to transfer such large amounts of data.
These periods of time may be so long as to make the performance unacceptable.
Additionally, with the precious spectrum resources, the cost of bandwidth on these networks is relatively high.
Thus, there is a vast amount of unused television broadcast spectrum available for other uses.

Embodiment Construction

[0014]FIG. 1 is a block diagram of a mobile communications system according to principles of the present invention. In FIG. 1, a mobile transceiver 10 is in bidirectional communications with a transmitting and receiving antenna 20. The antenna 20 is simultaneously connected to other mobile transceivers, e.g. 14. In addition, other transmitting and receiving antennas, such as antenna 22, are connected to the antenna 20 via a communications network 30. The other antennas, 22, are connected to other mobile transceivers, e.g. 12. In the embodiment illustrated in FIG. 1, the mobile transceivers 10, 12, 14, in cooperation with the antennas 20, 22, and with network 30, possibly including existing land line telephone networks (not shown), interoperate in a known manner for placing, receiving and carrying on wireless telephone conversations. In FIG. 1, the mobile transceiver 10 is configured as a personal communications system (PCS) device, and will be described in more detail below.

Abstract

A mobile communications system includes a plurality of mobile communications devices. A direct link communicates information between a communications network and a selected one of the plurality of mobile communications devices. A broadcast link simultaneously broadcasts information from the communications network intended to be receivable by the plurality of mobile communications devices.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a mobile, two-way, personal communications system. BACKGROUND OF THE INVENTION [0002] Personal communications systems (PCS) devices are based on mobile phone or cellular phone system devices. Mobile or cellular phone devices are currently configured to communicate with one of a plurality of permanently placed ground antennas, which, in turn, are connected to the telephone system: both to standard wired telephones and to other mobile or cellular telephone devices via other such ground antennas. The original cellular phone devices communicated via analog data signals. However, newer cellular phone devices communicate via digital data signals. In either case, there is a direct link between the telephone communications network and the cellular telephone. [0003] Further capabilities are being added to the digital cellular phone devices. For example, digital cellular phone devices are being enhanced to enable them to receive d...
