Introducing the solution: AT&T’s Microcell, or TMobile’s Wi-Fi CellSpot Router
Get one. You’ll go from 0 bars to as much as 5 full bars.
About the same size as an average-sized router, each device hooks up to another router or directly to a e.g. cable modem, and searches the net for the nearest yet strongest cell tower. Voila…connected.
Of course, you’ll need a carrier to begin with e.g. AT&T may be about $150.00; about 90-minute signal connection time; T-Mobile: may be free: $75 deposit which may be credited back to your account; near-instant connection time, etc…
