In the US they do now. Most Cell phones now either have a GPS unit built in, or will identify via some form of cell tower information. I think the requirement right now is to know where the phone is to within 100 feet or so. As for the metal building, you'd be surprised how well they work. The only troubles I had seen before where related to wireless devices that used similar radio space. When I worked for Ingram Book Company, the warehouse used wireless terminals to deal with inventory tracking and movements. These terminals used 900-930Mhz spread spectrum. This trampled all over the beeper frequencies that were available. Where ever the transmitters where strongest, you absolutely had no chance of being beeped. Move out farther into the warehouse where fewer transmitters where and you could get some through. -- Steven Critchfield <[EMAIL PROTECTED]> _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users
