Uh, overlapping and hierarchies only stand a chance of helping you if a handset can see more than two base stations. Are providers going to install extra base stations to enable you to triangulate your position? Doubting it. Not because of the cost of the BTS itself, but because of challenges getting permission for an antenna site then leasing T1/E1 lines to the central controller plus the desire to build out coverage to start before backfilling the holes. I believe Snaptrack and/or GPS is cheaper and offers unmatched coverage. Providers have no other requirement but to implement it in their web and 911 software then start raking in the cash.

Ilmarinen, you should keep in mind that the GPS signal is owned by the US government, and it is provided to the rest of the world on a gratis basis, and can be withdrawn and service denied at anytime when the US military decides (probably only in the event of conflict). Its primary purpose is to help our seagoing and airbound ships navigate, and our rockets deliver missiles into a pickle barrel across the ocean when we, or our friends elsewhere are threatened. The interesting and sometimes useful commercial usage of the system that we have seen in the recent years is nothing but doodly squat when you ponder its real purpose. regards, sa
