As it stands, they are much less likely to be sued by forcing you to activate E911 than by allowing you to not have it.

This can delay sending the emergency crews by a few vital minutes. (From a landline saying "right here" does work, as the 911 operator will have the address onscreen.)

      So the US has introduced Enhanced 911 (E911), which basically says that cellphone providers must be able to track their users location when they make a 911 call. This is usually done either by a GPS reciever in the handset or by fairly accurate positioning based on the cellphone signals (i.e. accuracy of a few meters, not just "this cell that covers a whole town").

      The additional catch is that VOIP is less reliable than traditional telephony, so 911 calls may be lost. People should know this so they can make an informed decision.

Essentially, the way AGPS works is that when the phone wants to know its location (typically because E911 has requested it), it asks the tower for help. The tower - which has a real GPS with a good fix and ephemeris data - tells the phone which satellites to listen for, and asks the phone to reply to the tower with what it's hearing, timestamped with the phone's received time information. The tower then takes the set of pseudorandom streams that the phone has relayed and the tower computes a location solution.

    It's a very clever way of (a) offloading most of the work to the tower, thus making it much cheaper to build GPS into all phones, and (b) making it possible for GPS fixes to be obtained in very minimal conditions - even inside buildings - because another receiver, one that does have a full view of the sky, and ephemeris data, is giving assistance.

Thus, it doesn't matter if your home has 911, but if your neighbor does. Does that make me a bad neighbor? I suppose in a way. Then again, if it's that vital, why aren't 911 enabled phones readily available on every other street corner?

    Ah, they used to be (payphones). Then came the cellphone, and everyone not able to pay the high cellphone charges watched as payphones became rarer. If 911 was so vital of a service, why did its public/free availability shrink merely due to increasing shareholder value. It's a scam, that's why. It was always about shareholder profits. This idea that 911 is a must have, but is only obtainable by subscribing to overpriced services. What's next, to get medical care at a hospital, I have to subscribe to the local newspaper? Fire trucks only for those who have memberships to the local golf club? Police only take stolen vehicle reports if you are an AAA member?

    And, yet, somehow, I'm the bad guy for not buying into the idea by purchasing a service I don't need or want.

  23. voice-interrupt for affirmative acknowledgement by davidwr · · Score: 2, Interesting

    The next time a VoIP customer tries to call a non-VoIP number, have the VoIP provider intercept the call with an annoying message saying "The FCC wants you to know that VoIP 911 services are not the same as land line 911 and may not work in an emergency. The FCC requires that we tell you and that you acknowledge that we have told you. To repeat this announcement, press 1, to acknowledge that you heard it and continue your call, press 2."

    This meets the "affirmative acknowledgement" requirement.
