In my humble opinion, it is going to be routed thru the cell phone intrastructure before it gets to the 911 center, and not the 911 tower. It is possible that the cell phone service has provided a small repeater transceiver, but I know nothing about that. And just less than a year ago things in California's 911 system were not all that wonderful: http://www.cnn.com/2010/TECH/mobile/09/08/emergency.numbers/index.htmldave54 wrote:YC 1 wrote:
Repeaters for police and fire will not pick up cell phone signals. If you are meaning their actual communications channels.
They use different frequencies and modulation techniques.
A separate antenna connected to different base unit on the same tower will receive 911 calls. Not too common yet, but increasing in mountainous rural areas.
Can you explain this a bit more please. Some new piece of communications equipment on the market?
Cell phones do not connect to 911 dispatch centers via their towers or radios. They connect via phone lines. The cell towers and vendors send that information via their infrastructure.
Also got me curious too so I did some research. I'm retired law enforcement and never heard of a cell phone being able to call 911 while it was in an area with no service. The only thing I could find on this is that if you don't have coverage from your own provider and you dial 911, that your phone should roam and search for any other provider and send the 911 call through them. So your phone may show no service, but if you are in the range of any other cell provider you can still make a 911 call. But this is all within the cell providers and not on the law enforcement network.
