If we are being required to pay for 911 service on our cell phone bills, then it is only reasonable to expect that it should work as best as it can, and that the technology will continue to improve over time, just as it has with landline 911.

| Re: Dumb While I don't exactly know what the 911 charge goes to pay, I could guess that there are a lot of salaries to be paid and current technology to be kept up.
If we want more from our E911 service then I think we shouldn't be asking "then why am I paying a fee", but rather we should be asking how much more we would need to spend to get the service we want.

However, the nanosecond there is any kind of natural disturbance, my cell phone service quits working and I'm shit outta luck with emergency services. Case in point: the EQ So Cal had on July 29, 2008. It was originally graded a 5.4 on the Richter, then the USGS downgraded to a 5.2, but the fact remained, although no lives were lost and multi billion dollar damages to the infrastructure was incurred -this time- I couldn't have called nine one one on the cell phone. So much for that service, eh?

However, the nanosecond there is any kind of natural disturbance, my cell phone service quits working and I'm shit outta luck with emergency services. What you are describing has nothing to do with E911. E911 was designed to allow emergency operators to locate a phone that dials 911 so they know where to send the first responders. What happened in your case was that when the EQ hit a few hundred thousand (maybe even over a million) people started dialing on their cell phones, and the towers and "cellular" networks got overloaded. E911 wont fix that issue, and realistically there is no way of fixing that issue. I'm not convinced E911 is strictly about locating First Responders. This paper elaborates and fully discusses the issue much better than "Kathyrn V"'s analysis above. Registration is free as is the paper itself. | |

This paper elaborates and fully discusses the issue much better than "Kathyrn V"'s analysis above. Registration is free as is the paper itself. Thats an incorrect assessment. E911 is used for one purpose, and one purpose only. It's sole purpose is to locate callers (geographically) so that first responders can find them in the event that they are incapacitated and can not speak or otherwise communicate with the operator. When dialing from a landline, E911 communicates the callers address to the nearest PSAP (public safety answering point. This allows the dispatcher to visually see what kinds of first responders are in closest proximity to the caller, and to subsequently dispatch them. Wireless E911 on the other hand, works a little differently. Given that you are calling from a mobile phone, that number (obviously) isnt tied to a physical address. In this case it is done using one (or more) forms of radiolocation to pinpoint the user. It has been a federal requirement that all handsets produced in recent years allow for radiolocation, most commonly in the form of GPS. Contrary to what most people believe, almost all newer phones have a GPS receiver in them just for this purpose (and no, you cant hack it to give you directions!). If the phone doesnt have GPS, the PSAP can triangulate your location based on the AoA (angle of arrival) that they determine when comparing the signal (to you) from at least two different cell towers. The other common method of locating a caller using E911 is TDOA (time difference of arrival). This method basically figures out your location based on the time it takes your phone to communicate with nearby towers.
The bottom line is that its pretty crazy how accurate E911 is, and most people dont even realize they can/are/will be tracked (and located) if they dial 911 from their cell phone!
