Abstract
A system and method for improving radio performance through automatic channel selection utilizing a closed-channel model is disclosed. A measurement engine records maximum user throughput on a per station basis during normal traffic operation. The measurement engine further records throughput metrics based on test traffic sent to all associated stations during idle operation. A policy logic engine utilizes the measurements to determine an optimal transmission channel for transmission and receipt of data.

A method for increasing quality of data transmission in a network having a plurality of transmission channels, the method comprising:
- determining an actual throughput of each of the plurality of transmission channels, during normal network traffic patterns;
- transmitting test data to the plurality of transmission channels, during an idle period of the network;
- measuring a test throughput of each of the plurality of transmission channels, responsive to said transmitting test data;
- determining transmission channel quality metrics for the plurality of transmission channels responsive to the actual throughputs and the test throughputs;
- determining whether an available transmission channel of the plurality of transmission channels has better channel quality metrics than the channel quality metrics of a current transmission channel of the plurality of transmission channels being used to transmit data;
- selecting the available transmission channel when the available transmission channel has a better channel quality metrics than the channel quality metrics of the current transmission channel;
- and
- maintaining the current transmission channel for data communication, when the available transmission channel does not have better channel quality metrics than the channel quality metrics of the current transmission channel.
A system for increasing quality of data transmission in a network having a plurality of transmission channels, comprising:
- a processor for determining an actual throughput of each of the plurality of transmission channels, during normal network traffic patterns;
- and
- a communication device coupled to the processor and the antenna apparatus for transmitting test data to the plurality of transmission channels via an antenna apparatus, during an idle period of the network, wherein the processor
- measures a test throughput of each of the plurality of transmission channels, responsive to said transmitting test data;
- determines transmission channel quality metrics for the plurality of transmission channels responsive to the actual throughputs and the test throughputs;
- determines whether an available transmission channel of the plurality of transmission channels has better channel quality metrics than the channel quality metrics of a current transmission channel of the plurality of transmission channels being used to transmit data;
- selects the available transmission channel when the available transmission channel has a better channel quality metrics than the channel quality metrics of the current transmission channel;
- and
- maintains the current transmission channel for data communication, when the available transmission channel does not have better channel quality metrics than the channel quality metrics of the current transmission channel.
A system for increasing quality of data transmission in a network having a plurality of transmission channels, comprising:
- means for determining an actual throughput of each of the plurality of transmission channels, during normal network traffic patterns;
- means for transmitting test data to the plurality of transmission channels, during an idle period of the network;
- means for measuring a test throughput of each of the plurality of transmission channels, responsive to said transmitting test data;
- means for determining transmission channel quality metrics for the plurality of transmission channels responsive to the actual throughputs and the test throughputs;
- means for determining whether an available transmission channel of the plurality of transmission channels has better channel quality metrics than the channel quality metrics of a current transmission channel of the plurality of transmission channels being used to transmit data;
- means for selecting the available transmission channel when the available transmission channel has a better channel quality metrics than the channel quality metrics of the current transmission channel;
- and
- means for maintaining the current transmission channel for data communication, when the available transmission channel does not have better channel quality metrics than the channel quality metrics of the current transmission channel.
