kudos:1 | whats wrong with everyone What the hell is it with all this Mesh networking? Does anyone fucking see that it eats up bandwidth like hell, Wifi has only 3 effective channels, and about 30mbit per channel real world, with p2p and streaming content, the mesh networks will rapidly come to a crawl. Each mesh node, needs a backhaul to a wired node, so cut the available bandwidth in half since each node must accept traffic, then send it out again over the same channel to the wired node, and that only has 30mbit at best, and serves 10s of other nodes, doesnt anyone see the problem? |

You have described the basic problems with one type of mesh network. There are a lot of ways to accomplish mesh networks.
Here is a nice white paper documenting a study.

You need fiber/multiple T1s/bonded DSL to each node, or out of band (not 2.4ghz) backhaul links between all nodes, preferably with directional antennas. |

The white paper... Believe it or not there are other people working this problem and they actually do understand it better than you ... or even I ... do.

kudos:1 | That white paper shows nothing, all he did was run a computer simulation of estimated coverage and permutations of node paths. That has little to no info on congested nodes and retransmission penalty and other factors. |
