Abstract
The present invention comprises a system and method for improving voice quality of cordless communications. The system comprises at least one mobile unit having circuitry for maintaining an individual communication link with a base station. The system also has logic residing in the base station for selecting a frequency to maintain the communication link, monitoring parameters relating to the quality of the frequency, and performing data correction on the frequency in response to the monitored quality of the frequency.
Claims32
A system for improving voice quality in cordless communications, comprising:
- a) at least one mobile unit operable to transmit and receive data at a plurality of frequencies over a communication link;
- and
- b) a base station operable to transmit and receive data over the communication link, the base station comprising logic operable to:
- select a frequency from the plurality of frequencies to transmit and receive data over the communication link,
- monitor during a first time period at least one parameter relating to the quality of the selected frequency,
- select, after the first time period, another frequency from the plurality of frequencies to transmit and receive data over the communication link;
- select, during a second time period subsequent to a selection of the another frequency, the frequency that was monitored during the first time period;
- and
- perform, during the second time period, at least one error correction on the frequency in response to the monitored frequency quality monitored during the first time period.

A method for improving voice quality in cordless communications, comprising:
- selecting a unique carrier frequency over an individual communication link, the communication link operable to carry data between at least one mobile unit and a base station;
- monitoring the quality of the selected frequency during a first time period;
- selecting another frequency after the first time period to transmit and receive data over the communication link;
- after selecting the another frequency, selecting, during a second time period, the frequency that was monitored during the first time period;
- and
- performing, during the second time period, error correction on the selected frequency in response to the monitored quality monitored during the first time period.
3 more elements
A method for improving voice quality in cordless communications, comprising:
- providing a base station and at least one mobile unit;
- sending data using a selected frequency over an individual communication link between the base station and the mobile unit during a first time period, the communication link associated with the mobile unit;
- evaluating, during the first time period, the selected frequency used on the associated communication link to determine the transmission quality of the selected frequency;
- after the first time period, sending data using another selected frequency over the individual communication link;
- after sending data using the another selected frequency, sending data during a second time period using the selected frequency that was used during the first time period;
- performing, during the second time period, error correction on the selected frequency if the transmission quality was evaluated as unacceptable during the first time period;
- and
- repeating the process for a second mobile unit.
