Google for Wireless Mesh and I’ll see you on the other side. These document authors REALLY need to look a the OSI Model and work out the difference between Layer 2 and Layer 3 technologies. Anyway – I highly recommend you read http://www.proxim.com/learn/library/whitepapers/mesh_primer_PP3-1005.pdf if you have an interest in setting up a Wireless Mesh. My definition of this is a number of Access Points covering an area that are NOT connected by Cat 5 to a backbone, but rather a multi-hop wireless, IN A SINGLE SUBNET. Proxim seems to be one of the few with a clue. Implementing solution atm – will advise results.
Results were dismal at the time. Advise extreme caution in this space.
