This is a pretty poor article in the International Herald Tribune about how mesh networks could help in emergencies like the recent bombs in London: The article defines mesh thus: “it links disparate hot spots into a single, expandable broadband wireless network.” It also says that mesh would have been particularly useful in London because there are lots of hotspots there already. To me, that sounds like mesh would connect a bunch of scattered hotspots that might be far away from each other and might be owned by different people. That’s not at all the case. In fact, the key to mesh is that every hotspot doesn’t require backhaul. Instead, hotspots can pass traffic one to the next until hitting one that connects to the Internet. But mesh doesn’t somehow magically connect different networks or hotspots that are individually owned. Also, like any wireless network, a mesh network could get so congested by users that it can’t carry any more traffic.
