Wireless 911 Stats

[MrJim911]

120.9 million wireless subscribers, mostly cellular telephones, with 46,000 new subscribers added daily

140,000 wireless calls to 911 daily/51 million estimated in 2000 which is about 20% of all 911 calls received (CTIA). This is an increase over figures for 1996: 59,180 per day, and 21.6 million for the year, and an increase over 1994's daily volume of 49,000 calls on 911 per day or 137,000 wireless 911 calls per day, or 50 million each year, which constitute 26.5% of all 911 calls (NENA, 2001)

The FCC has set various deadlines and technical requirements for carriers to provide wireless E911 location features. They are designated as Phase I (provide caller's telephone number and location of receiving antenna site), and Phase II (provide caller's physical location). As of March 1999, only 7% of comm centers had requested Phase I features from their local wireless carriers. As of Dec. 2001 only two cities had Phase II service. (NENA, 2001).

As of January, 2000 NENA says that just 8% of jurisdictions have implemented Phase I features.

There are over 66,800 cellular receiver sites, with more being added daily (CTIA, 2001).

International Data Corp. (IDC) says commercial location-based services should reach $590 million in revenues by 2001, and $5 billion by 2004.

The European market for location services could total $20 billion to $33 billion in revenue by 2005.

Try having "914" as a cell phone prefix in your area! We probably respond to at least 10 911 calls a day where people were trying to call the "914" of someone's cell phone and accidentally dial 911. I'm not sure which cell phone company is using that number, but I'd sure like to give them a piece of my mind! We also respond to a few calls a day where people were trying to dial "411".

Are you required to respond to all 911 disconnects from homes/businesses? Or does your dispatch make the decision based on what they hear or do they call back to see if they can reach someone?

And how can you respond to cellular 911 calls since you don't know where they are at?

[kenoshacop]

We are required to respond to all 911 calls. Dispatch advises us what if anything they hear, and they callback to try and make contact if it is a disconnect.

As far as your second question, I guess I should have been a little clearer in my last post. The accidental 911calls that were supposed to be 914 cell phone #'s we go to are from home phones, not other cell phones. We have no way of knowing where the cell phone call comes from unless the person calling tells us their location.
