Well, it seems ridiculous to say that, because there have been 3g microcells (openbsc, for example) forever. It seems bizarre that we couldn't have a switch in every truck that turns it into a mobile microcell for <$100. The backhaul is the problem, because normal microcells are connected to the internet via hardline IP communication . . . . which could be done with modern satellite. The problem is that if you are selling anything to any kind of government agency, you absolutely want them _not_ to be able to use any commodity component like a "cell phone"
