Method and apparatus providing simultaneous dual mode operations for radios in the shared spectrum

A dual mode RF radio comprising:

• a first transceiver operating under a first transmitter/receiver protocol in an RF band, and having a first receiver portion and a first transmitter portion therein;
• and a second transceiver operating under a second transmitter/receiver protocol in the same RF band as the first transmitter/receiver, and having a second receiver portion and a second transmitter portion therein;
• wherein both transmitter/receiver protocols are time division duplex protocols having non-synchronous transmissions;
• a shared antenna operatively connected to both said first transceiver and said second transceiver;
• a main processor operatively connected to both transceivers and a collision avoidance mechanism for determining which of the frequencies in the spread spectrum will be used by each of said transceivers for a next transmission;
• and
• an isolation mechanism for isolating said first and second receiver portions from a transmitter portion while said transmitter portion is transmitting to reduce desensitization.

A method of simultaneously operating a dual mode RF radio comprising:

• operating a first transceiver under a first transmitter/receiver protocol in an RF band;
• operating a second transceiver under a second transmitter/receiver protocol in the RF band, wherein both transmitter/receiver protocols are time division duplex protocols having non-synchronous transmissions;
• sharing an antenna between the first transceiver and the second transceiver;
• and
• isolating the receiver portions of the transceivers from the transmitter portion of the transceivers while a transmitter portion is transmitting to reduce desensitization.
