Just a quick one on this new link.
Wireless Mesh is the technology that basically connects Wireless Access Points into a network using a wireless backhaul in place of wires. This technology has mostly been developed in the 802.11 space. Obviously there are thinking to use for WiMAX type deployments to save on backhaul cost and setup.
This link gives very good overview of the protocol and also outlines the current trends.
