(If not, the moderator may wish to divert the discussion). Clearly a customer can rent a cellular phone, and register for service in a particular area; then they can both send and receive calls. The technology somehow recognizes and notes the user's location as they drive about, and knows in what cell to ring them if an outsider calls them. The questions: 1. How is the location-recognition accomplished? Does one's currently inactive cellular phone burp regularly and its address get re-noted? Does that drain your battery? If it's really off are callers told something different from "ring...ring...ring...no answer"? 2. Over how large an area does this typically work? 3. If an owner drives from SF, normal location, to New York, and tries to call out, what happens? 4. If while they are in New York, someone in SF, their home, calls them, what happens? 5. Can you register as a visitor in a distant area, electronically or by calling in or however? Does this enable anyone else to call you from long distance? Must they know, essentially, where you went and when you're there? Thanks, Doug [ cellular inquiry
