Executive Summary

Wireless mesh network technology provides a quick method of providing network access. Traditional wireless mesh networks face problems regarding spatial reuse. The simultaneous use of multiple interfaces and channels attempts to solve this problem. Support for these multiple channels and devices have been implemented through the Net-X system. Performance of the network depends on the amount of cross channel interference because wireless transmissions use a shared medium and interfere with each other unless properly separated in distance and frequency. The authors test the interference experienced in single, dual, and triple interface nodes. A protocol needs to support the most common types of TCP and UDP traffic for it to be useful.
