Method and apparatus for a signal selective RF transceiver system
View Patent ↗Method and apparatus to dynamically configure the signal reception selectivity of a plurality of transceivers is described. In one embodiment, a transceiver includes a receiver circuit having two or more filter circuits. Each of the filter circuits is configured to pass RF signals from a different portion of an overall receiver bandwidth. When two or more receivers in proximity to one another are simultaneously operating, the filter circuits of the respective receiver are dynamically configured to different RF frequency passbands to minimize interference and cross talk between receivers and transmitters.
1. An RF device comprising:
a receiver configured to utilize a random access communications protocol, the receiver being implemented on a radio card having a slot number and a slot location;
a channel detector configured to determine an available frequency from a plurality of frequencies;
a filter circuit including a plurality of filters, each filter being associated with at least one frequency of the plurality of frequencies, and each filter having a different frequency passband than other filters of the plurality of filters; and
a controller configured to set the filter circuit to pass the available frequency via a selected filter based on at least one of the slot number and the slot location.
2. The RF device according to claim 1 , wherein the device utilizes the 802.11 protocol.
3. The RF device according to claim 1 , wherein the filter circuit includes at least one passband filter that passes the available frequency.
4. The RF device according to claim 3 , wherein the passband filter passes a band of 802.11 regulated frequencies.
5. The RF device according to claim 1 , wherein the filter circuit comprises a filter module detachably coupled to the receiver.
6. The RF device of claim 1 , wherein each filter has a different passband.
7. The RF device of claim 1 , wherein each filter passes a different frequency/passband.
8. The RF device of claim 1 , wherein the filter circuit is configurable to switch between sets of the plurality of filters.
9. The RF device of claim 1 , further comprising a transmitter, wherein the RF device is configured for simultaneous transmission and reception.
10. The RF device of claim 1 , wherein the random access protocol is one of CSMA and DCF.
