Use of Overlapping Channels for Expanded Wireless Communications
WARF: P06353US
Inventors: Suman Banerjee, Vivek Shrivastava, Arunesh Mishra
The Wisconsin Alumni Research Foundation (WARF) is seeking commercial partners interested in developing a method for the simultaneous use of overlapping wireless communication channels.
Overview
Wireless communication devices typically operate in one of two bands of the electromagnetic spectrum. The bands are divided into several channels set at center frequencies, but many partially overlap each other. Due to the interference between partially overlapped channels, their simultaneous use generally has been avoided, limiting devices’ throughput.
The Invention
UW-Madison researchers have developed a method for the simultaneous use of overlapping wireless communication channels, providing substantially higher throughput. They developed criteria for characterizing the interference levels that can arise as a result of any given arrangement of wireless communication devices operating at different channels. This provides a method for controlling interference levels, allowing the overlap of channels while keeping interference within acceptable, predetermined bounds.
Applications
- Wireless communications
Key Benefits
- Allows the use of more adjacent channels than conventional methods, substantially increasing throughput
- Devices may be programmed to self-adjust when encountering a preprogrammed maximum level of interference.
