Abstract
A method includes monitoring a variable-rate data communication channel to determine its signal-to-noise ratio, and adjusting the data transmission rate of the variable rate data communication channel based on its signal-to-noise ratio.
Claims39
A method comprising:
- monitoring a variable-rate data communication channel to determine its signal-to-noise ratio;
- and
- iteratively adjusting the data transmission rate of the variable rate data communication channel if the signal-to-noise ratio of the communication channel cannot be determined for a defined period of time.
A data transmission rate control process comprising:
- an SNR determination process for monitoring a variable-rate data communication channel during a non-transmission period to determine its signal-to-noise ratio;
- and
- an iterative rate determination process, responsive to said SNR determination process being unable to determine the signal-to-noise ratio of said variable-rate data communication channel for a defined period of time, for setting the data transmission rate of said variable rate data communication channel.
A computer program product residing on a computer readable medium having instructions stored thereon which, when executed by the processor, cause that processor to:
- monitor a variable-rate data a communication channel during a non-transmission period to determine its signal-to-noise ratio;
- and
- iteratively adjust the data transmission rate of the variable-rate data communication channel if the signal-to-noise ratio of the communication channel cannot be determined for a defined period of time.
A data transmission rate control system comprising:
- a first computing device including a first wireless communication system;
- a second computing device including a second wireless communication system, wherein said first and second wireless communication systems form a variable rate data communication channel between said first and second computing devices;
- wherein each said wireless communication system includes:
- a SNR determination process for monitoring said variable-rate data communication channel during a non-transmission period to determine its signal-to-noise ratio;
- and
- an iterative rate determination process, responsive to said SNR determination process being unable to determine the signal-to-noise ratio of said variable-rate data communication channel for a defined period of time, for setting the data transmission rate of said variable rate data communication channel.
