Mobile carriers put tiny cells all over the place if there's likely to
be significant usage. You find them, for example, in the tunnels
under Boston harbor so people can continue talking on their cell
phones while they drive as fast as possible to the airport. (Boston
traffic is already so chaotic that the extra safety hazard is

If there's a lot of people in building and crummy cell coverage, it
might be fun to call a cell carrier or two and see if they're willing
to put in a picocell. I would imagine that some buildings with steel
insides might be impractical to cover since the frames act like a
Faraday cage and kill any signals.
