Broadband wireless communications systems and methods using multiple non-contiguous frequency bands/segments
View Patent ↗Wireless communications transceivers include a transmitter that is configured to selectively frequency shift and transmit portions of broadband information over multiple non-contiguous narrowband frequency bands/segments, each of which is too narrow to carry the broadband information. A receiver also is configured to receive and selectively frequency shift portions of broadband information from multiple non-contiguous narrowband frequency bands/segments, each of which is too narrow to carry the second broadband information. Broadband information thereby may be transmitted and received in a regulated communications environment, even though a given provider may only be assigned discontinuous frequency bands/segments, none of which is wide enough to carry the entire broadband information.
1. A radioterminal comprising:
a receiver that is configured to receive and selectively frequency shift portions of broadband information from a base station over a plurality of non-contiguous narrowband frequency bands/segments, each of which is too narrow to carry the broadband information from the base station, so as to receive the broadband information from the base station over the plurality of non-contiguous narrowband frequency bands/segments;
wherein the receiver is further configured to receive the broadband information in its entirety using only the plurality of non-contiguous frequency bands/segments.
2. A radioterminal according to claim 1 wherein the base station comprises a space-based component, a terrestrial base station and/or an ancillary terrestrial component.
3. A radioterminal according to claim 1 wherein the plurality of non-contiguous narrowband frequency bands/segments are satellite narrowband frequency bands/segments.
4. A radioterminal according to claim 3 wherein the non-contiguous narrowband satellite frequency bands/segments are in L-band.
5. A radioterminal receiving method comprising:
receiving and frequency shifting portions of broadband information from a base station over a plurality of non-contiguous narrowband frequency bands/segments, each of which is too narrow to carry the broadband information from the base station, so as to receive the broadband information from the base station over the plurality of non-contiguous narrowband frequency bands/segments;
wherein the receiving and frequency shifting further comprises receiving the broadband information in its entirety using only the plurality of non-contiguous frequency bands/segments.
6. A method according to claim 5 wherein the base station comprises a space-based component, a terrestrial base station and/or an ancillary terrestrial component.
7. A method according to claim 5 wherein the plurality of non-contiguous narrowband frequency bands/segments are satellite narrowband frequency bands/segments.
8. A method according to claim 7 wherein the non-contiguous narrowband satellite frequency bands/segments are in L-band.
