Abstract
The present invention provides a multiple band mobile radio (also referred to as a Wireless Communication Device (WCD)) capable of communicating with both a satellite communication system and a terrestrial communication system. The satellite communication system can be, for example, a Low Earth Orbit (LEO) satellite system. The terrestrial communication system can be a Personal Communication System (PCS), or a cellular system, including either an analog or a digitally based cellular system. The cellular analog system can be AMPS. The digitally based cellular system can be a CDMA or a TDMA based communication system. The WCD can concurrently receive signals from the terrestrial communication system and the satellite communication system.
Claims41
A multi-mode Wireless Communication Device (WCD) for communicating with a satellite communication system and a at least one of several terrestrial communication systems, comprising:
- a satellite transmit channel to produce a satellite Radio Frequency (RF) transmit signal to be transmitted to at least one satellite of the satellite communication system;
- a satellite receive channel to receive and process an RF signal transmitted by at least one satellite;
- a terrestrial transmit channel to produce a terrestrial RF transmit signal to be transmitted to at least one of a plurality of terrestrial communication systems;
- and
- a terrestrial receive channel to receive and process an RF signal transmitted by at least one of a plurality of the terrestrial communication systems, being configured to allow concurrent communication with said satellite receive channel.
A method for communicating with a satellite communication system and at least one terrestrial communication system, comprising:
- producing a satellite Radio Frequency (RF) transmit signal to be transmitted to at least one satellite of the satellite communication system;
- receiving and processing an RF signal transmitted by at least one satellite;
- producing a terrestrial RF transmit signal to be transmitted to at least one of a plurality of terrestrial communication systems;
- and
- receiving and processing an RF signal transmitted by at least one of a plurality of terrestrial communication systems, on occasion concurrent with satellite signal reception.
Apparatus for communicating with a satellite communication system and at least one terrestrial communication system, comprising:
- means for producing a satellite Radio Frequency (RF) transmit signal to be transmitted to at least one satellite of the satellite communication system;
- means for receiving and processing an RF signal transmitted by at least one satellite;
- means for producing a terrestrial RF transmit signal to be transmitted to at least one terrestrial communication systems;
- and
- means for receiving and processing an RF signal transmitted by the terrestrial communication systems, being configured to allow concurrent communication with said satellite receive channel.
Apparatus for communicating with a satellite communication system and a terrestrial communication system, comprising:
- means for producing a satellite Radio Frequency (RF) transmit signal to be transmitted to at least one satellite of the satellite communication system over a satellite transmit channel;
- means for receiving and processing an RF signal transmitted by at least one satellite over a satellite receive channel;
- means for producing a terrestrial RF transmit signal to be transmitted to at least one terrestrial communication system over a terrestrial transmit channel;
- and
- means for receiving and processing an RF signal transmitted by the terrestrial communication system over a terrestrial receive channel, being configured to allow concurrent communication with said satellite receive channel.
