The plan is to build a muilt-radio mesh networking system that could be placed in disaster situations or used in search and rescue operations. The idea is that if we can cover an area with WiFi we could expand the resources available at any one place in the area.
Looking at using B.A.T.M.A.N. advanced as the mesh backed and looking in to what kind of WiFi based two-way radios there might be. If I find none I may have to do that as well.
