IEEE Evaluates Mesh Proposals

Among the 15 proposals are single-company and consortia-submitted proposals from industry networking giants including Nortel Networks Ltd. and Nokia Corp., all of which already offer proprietary mesh networking products. In a mesh network, packets are routed dynamically from node to node, and only one access point needs to be connected directly to the wired network. The proposals all are variations on that theme.
The proposal from the Wi-Mesh Alliance, led by Nortel, supports both single- and multiple-radio mesh architectures. It is designed to be extensible and compatible with the upcoming 802.11n high-throughput Wi-Fi standard, said Nortel officials in Toronto. Nortel has already deployed mesh networks in Taipei City, Taiwan, and at several universities. Other members of the alliance include Accton Technology Corp., NextHop Technologies Inc. and The Thomson Corp.
