Wireless Mesh: New Wave Broadband
A new wave of wireless mesh infrastructure is transforming the way large metro, campus, and enterprise 802.11 networks are built. Mesh topologies introduce enormous flexibility into wireless networks by eliminating, or seriously reducing, the restrictions of wired backhaul, resulting in lower costs and faster deployment.

Problems of scaleability, throughput, latency, and routing protocol-overhead still exist, but by applying techniques such as multi-radio mesh nodes and enhanced routing algorithms to commercial-off-the-shelf components, systems under development today overcome many of the drawbacks found in first-generation products.

Vendors are working to provide modular, multiservice network architectures that incorporate essential networking features such as QOS, fast handoff, security, and system management. Many products have been designed to accommodate 802.11n (MIMO) and 802.16 (WiMax) radios in the future. In some cases, vendors have even provided support for 2G and 3G picocells.
Sample research data from the report is shown in the excerpts below:
Table of Contents (uni0305_toc.pdf)
Infrastructure mesh is being developed for a wide range of network types and usage scenarios, including mixed-use public/private metropolitan networks, public safety, and the enterprise. A number of vendors are also working on hybrid (infrastructure + mobile mesh) systems. The chart below summarizes which markets and applications are targeted by which vendors.
