Abstract
In one example, a communication device is disclosed, which includes a tunable circuit coupled to an antenna, a modem, and a control unit. The modem may poll a plurality of channels. Each channel is associated with a frequency band. Further, the modem may record a received signal strength indicator (RSSI) value associated with each of the plurality of channels. Furthermore, the control unit may determine a first channel having a highest RSSI value from the plurality of channels and control the tunable circuit to tune the antenna based on a frequency of the first channel.
Claims13
A communication device, comprising:
- a tunable circuit coupled to an antenna;
- a modem to:
- poll a plurality of channels, each channel associated with a frequency band;
- and
- record a received signal strength indicator (RSSI) value associated with each of the plurality of channels;
- and
- a control unit to:
- determine a first channel having a highest RSSI value from the plurality of channels;
- control the tunable circuit to tune the antenna based on a frequency of the first channel;
- and
- trigger the modem to initiate the polling of the plurality of channels based on a region code parameter associated with the communication device when the RSSI value of each of the plurality of channels is less than a threshold value,
- wherein frequency ranges associated with a base station in a geographic region where the communication device is located are polled based on the region code parameter that indicates the geographic region.
A method comprising:
- enabling a modem to poll a plurality of channels, each channel associated with a frequency band;
- obtaining a received signal strength indicator (RSSI) value associated with each of the plurality of channels;
- comparing the RSSI value associated with each of the plurality of channels with a threshold value;
- determining a first channel having the RSSI value greater than the threshold value;
- providing a control signal to tune an antenna of a communication device based on a frequency associated with the first channel;
- and
- enabling the modem to initiate the polling of the plurality of channels based on a region code parameter associated with the communication device when the RSSI value of each of the plurality of channels is less than the threshold value,
- wherein frequency ranges associated with a base station in a geographic regio where the communication device is located are polled based on the region code paramenter that indicates the geographic region.
A non-transitory computer-readable storage medium comprising instructions that, when executed by a processor, cause the processor to:
- trigger a modem to poll a plurality of channels, each channel associated with a frequency band;
- receive a received signal strength indicator (RSSI) value associated with each of the plurality of channels from the modem;
- determine a first channel having a highest RSSI value from the plurality of channels;
- adjust a tunable circuit to tune an operating frequency of the antenna to a frequency of the first channel;
- and
- trigger the modem to initiate the polling of the plurality of channels based on a region code parameter associated with the communication device when the RSSI value of each of the plurality of channels is less than a threshold value,
- wherein frequency ranges associated with a base station in a geographic region where the communication device is located are polled based on the region code parameter that indicates the geographic region.
