Abstract

A wireless device that includes a Ultra High Frequency/Very High Frequency (UHF/VHF) based radio to cognitively search for and use vacant channels and multiple MIMO based radios siliconized with the UHF/VHF based radio.

Claims

1. A communication system, comprising:

a combination of Ultra High Frequency/Very High Frequency (UHF/VHF) and Multiple Input Multiple Output (MIMO) based radios, wherein first and second MIMO based radios have transmitters/receivers coupled to first and second antennas and the UHF/VHF based radio has a transmitter/receiver coupled to a third antenna.

2. The communication system of claim 1 wherein the first and second MIMO based radios and the UHF/VHF based radio are siliconized in a Wireless Local Area Network (WLAN) radio device.

3. The communication system of claim 1 wherein the first and second MIMO based radios have radio links with multiple antennas at the transmitter and the receiver side and the UHF/VHF based radio has a radio link with the third antenna at the transmitter/receiver.

4. The communication system of claim 1 wherein the UHF/VHF based radio is a cognitive radio that searches for and uses vacant channels in the 50 to 800 MHz frequency band.

5. A wireless device, comprising:

a transceiver of the wireless device utilizing Multiple Input Multiple Output (MIMO) based radios with first and second transmitters to couple to first and second antennas and a Ultra High Frequency/Very High Frequency (UHF/VHF) based radio to couple to a third antenna.

6. The wireless device of claim 5 wherein the transceiver is a Wireless Local Area Network (WLAN) transceiver.

7. The wireless device of claim 5 wherein the transceiver uses an Orthogonal Frequency Division Multiplexing (OFDM) modulation technique.

8. The wireless device of claim 5 wherein the transceiver is a Code Division Multiple Access (CDMA) transceiver.

9. The wireless device of claim 5 wherein the transceiver processes Direct-Sequence Spread Spectrum (DSSS) channels.

10. The wireless device of claim 5 wherein the transceiver operates across a license exempt band.

11. The wireless device of claim 5 wherein the first and second transmitters transmit data in a 2.4 GHz to 2.5 GHz range or a 5.150 GHz to 5.825 GHz range and the UHF/VHF based radio transmits in a 50 MHz to 800 MHz range.

12. A multiple-antenna communication system, comprising:

two transmitters that employ Multiple Input Multiple Output (MIMO) to provide radio links to first and second antenna; and

a third transmitter coupled to a third antenna to provide a Ultra High Frequency/Very High Frequency (UHF/VHF) based radio, where the two transmitters and the third transmitter are siliconized.

13. The multiple-antenna communication system of claim 12 further including two receivers to resolve the two data streams from the first and second antenna and a third receiver to resolve a third data stream from the third antenna.

14. The multiple-antenna communication system of claim 12 wherein the two transmitters and the third transmitter, and the two receivers and the third receiver are in a Wireless Local Area Network (WLAN) radio device.

15. A wireless device comprising:

a Ultra High Frequency/Very High Frequency (UHF/VHF) based radio to cognitively search for and use vacant channels; and

first and second MIMO based radios siliconized with the UHF/VHF based radio in the wireless device.

16. The wireless device of claim 15 wherein the UHF/VHF based radio uses vacant channels in the 50 to 800 MHz frequency band.

17. The wireless device of claim 15 further including first and second processing cores in the wireless device.

18. The wireless device of claim 15 wherein the wireless device operates as a Wireless Local Area Network (WLAN) device.

19. The wireless device of claim 15 wherein the UHF/VHF based radio includes a cognitive engine to optimize the operation of the wireless device across radio bands.

20. The wireless device of claim 15 wherein the UHF/VHF based radio receives streaming high definition video.
