Abstract
Methods and apparatuses for multiple RF band operation in mobile devices are disclosed. In one example, a method for dual radio frequency band operation includes operating a mobile communication device in a first radio frequency band, monitoring a RSSI associated with the mobile communication device, and switching operation of the mobile communication device to operation in a second radio frequency band responsive to the RSSI crossing a threshold RSSI value.
Claims15
A method for dual radio frequency band operation comprising:
- operating a mobile communication device in a first radio frequency band;
- monitoring a RSSI associated with the mobile communication device;
- monitoring a plurality of interference levels in a plurality of channels in a second radio frequency band while operating in the first radio frequency band;
- and
- switching operation of the mobile communication device to operation in a second radio frequency band responsive to the RSSI crossing a threshold RSSI value and selecting a channel within the second radio frequency band based on the plurality of interference levels.
2 more elements
A headset comprising:
- a microphone;
- a speaker;
- a processor;
- a first radio frequency band transceiver operable to transmit and receive signals in a first radio frequency band;
- a second radio frequency band transceiver operable to transmit and receive signals and a second radio frequency band;
- and
- a memory storing a radio frequency transceiver selection application configured to monitor a plurality of interference levels in a plurality of channels in both the first radio frequency band and the second radio frequency band and switch headset operation between the first radio frequency band transceiver and the second radio frequency band transceiver responsive to a monitored RSSI value crossing a threshold RSSI value, wherein the radio frequency transceiver selection application is configured to select a low interference channel identified from the plurality of interference levels when switching headset operation between the first radio frequency band transceiver and the second radio frequency band transceiver.
