Abstract
A system, communications device, method and computer program product for implementing antenna diversity may include a first switch to selectively connect a first radio section to one of a plurality of antennas and a second switch to selectively connect a second radio section to one of the plurality of antennas. The system may also include an antenna detector to detect which one of the plurality of antennas is connected to a port of the first radio section and to a port of the second radio section.
Claims42
A system for implementing antenna diversity, comprising:
- a first type of radio transceiver;
- a second type of radio transceiver;
- an electronic selector module that:
- controls one or more control lines associated with a plurality of SPDT switches to toggle the first type of radio transceiver and the second type of radio transceiver between a plurality of antennas, wherein in a non-compressed mode of operation, the electronic selector module allows simultaneous operation of the first type of radio transceiver and the second type of radio transceiver;
- a first single-pole double-throw (“SPDT”) switch comprising two poles and a common terminal, the SPDT switch being controlled by the electronic selector module to selectively connect the first type of radio transceiver to at least one of a plurality of antennas;
- a second SPDT switch comprising two poles and a common terminal, the SPDT switch being controlled by the electronic selector module to selectively connect the second type of radio transceiver to at least one of the plurality of antennas such that the first type of radio transceiver is connected to one of the plurality of antennas when the second type of radio transceiver is connected to another one of the plurality of antennas;
- an antenna detector configured to detect which of the plurality of antennas is connected to a port of the first type radio of transceiver and which of the plurality of antennas is connected to a port of the second type of radio transceiver;
- wherein the system is further configured to:
- measure a communication parameter associated with operation of the first or second type of radio transceiver on a first antenna;
- determine whether the communication parameter falls below a predetermined level;
- and
- in response to determining the communication parameter falls below the predetermined level, prompting a user of the system to switch operation of the first or second type of radio transceiver to a second antenna.
