    There are about 240 million 911 calls each year. There are about 900,000 sworn police officers nationwide. That's about 266 calls annually per police officer. Given there are about 240 work days per year (5 per week, 2 weeks vacation, 2 weeks of holidays), that's a little more than 1 call per day. There were about 10,550,000 arrests in 2017, or about 1 per month per police officer. So they're responding to about 22 more dispatches (from 911) than they are arresting. What are the odds your average police officer will only arrest things he sees happening on the street, and not any from the 22 dispatches per month?

  2. Some actual facts, if you are interested by kenh · · Score: 1 · on Why Uber Can Find You but 911 Can't (wsj.com)

    See here to learn that 99% of 911 call centers are capable of handling cellphone-generated GPS locations, but it relies on carrier upgrades outside their direct control.

    Or, you know, take the bait, assume the 911 system has remained stagnant for the last two decades, and feign false outrage over this non-issue.

  3. The answer is simple by kenh · · Score: 1 · on Why Uber Can Find You but 911 Can't (wsj.com)

    The 911 system was put in place before cell phones included GPS locators, and to retrofit the system with a new capability would be quite expensive. Any idea how many 911 call centers there are across America? 5,783

    According to a 911 industry group:

    99.4% of PSAPs have some Phase I
    99.0% of PSAPs have some Phase II

    Phase I - Cellphone carrier provides caller's number and cell tower calculated location
    Phase II - Cellphone carrier provides caller's number and cellphone calculated location

    Shockingly, this isn't nearly the "crisis issue" the click-bait headline would have you believe, and it is actually being implemented today.

    U.S. regulators estimate as many as 10,000 lives could be saved each year if the 911 emergency dispatching system were able to get to callers one minute faster.

    Are they really asserting that as many as 10,000 deaths per year because first-responders got to the location up to 60 seconds too late? That seems a bit fantastical, and the reader is supposed to assume that the issue is that first-responders got lost on the way to the location and it has nothing to do with traffic between the first responder and the victim, delays calling 911 as helpful neighbors try and help rather than call 911, etc.

    There's been a 'next-generation' 911 effort going on for some years now that will encompass VoIP, video, text and IM from your mobile and PC device. The text/IM stuff is envisioned as a replacement for the current system for the deaf. There will also be better location information and better call routing. http://www.nena.org/ has more.

  5. That approach was rejected by NENA by Animats · · Score: 1 · on Vonage 911 Deadline Passed
    The National Emergency Number Association rejected that approach. Here's their analysis (.doc format). The major problems are 1) calls forwarded in this way don't appear at the Public Safety Answering Point with useful location or caller ID information, 2) congestion is badly handled, 3) aiming multiple providers at the same group of numbers means that a routing error at one provider impacts 911 calls via other providers, 4) denial of service attacks become easy, and 5) components with lower reliability requirements are now in the 911 chain, but not identified as such.

  7. Re:Price~ Wireless 9-1-1(wandering off topic) by Clix · · Score: 1 · on What Has Number Portability Done For You?

    Are we thinking about the same 'Phases'?
    The phase one I'm familar with is getting Automatic Number Information (ANI - like callerid) from the wireless phones, phase two is getting locations.
    The E9-1-1 center I work at has had phase I (as I know it) for a while. We've been bringing phase II online for a few months. The reason it's taking so long for us to do phase II is that the Feds didn't mandate one standard, leaving it up to the different carriers. This is causing us to configure a seperate interface for each carrier. The ones that are on line now (Sprint, Verizion, AT&T amoung others) are giving us good (for the most part) locations on the 9-1-1 calls.
    Just curious.

    below from: HREF=http://www.nena.org/Wireless911/Overview.htm
    "Three Phases of Wireless 9-1-1 There are 3 phases that are referred to in implementing Wireless 9-1-1. The most basic of these, sometimes called Wireless Phase 0, simply means that when you dial 9-1-1 from your cell phone a call taker at a public safety answering point (PSAP) answers. The call taker may be at a state highway patrol PSAP, at a city or county PSAP up to hundreds of miles away, or at a local PSAP, depending on how the wireless 9-1-1 call is routed.
    Wireless Phase I is the first step in providing better emergency response service to wireless 9-1-1 callers. When Phase I has been implemented, a wireless 9-1-1 call will come into the PSAP with the wireless phone call back number. This is important in the event the cell phone call is dropped, and may even allow PSAP employees to work with the wireless company to identify the wireless subscriber. However, Phase I still doesn't help call takers locate emergency victims or callers.
    To locate wireless 9-1-1 callers, Phase II must have been implemented in the area by local 9-1-1 systems and wireless carriers. Phase II allows call takers to receive both the caller's wireless phone number and their location information."
