This above map represents the difference in the percentage of wireless 9-1-1 calls received at Connecticut's 107 PSAPs from 2002and 2007 by subtracting the 2002 wireless percentage from the2007 wireless percentage (see wireless maps to the right). For example, if a PSAP had a 2002 percentage of 25% and a 2007 percentage of 55%, its percent difference would be 30% and would be placed in the 26% to 50% category.

THE CHANGING WAY WE CALL 9-1-1According to the National Emergency Number Association (NENA),an estimated 240+ million calls were made to 9-1-1 in 2006. Ofthose calls, at least 100 million of them were made by wirelesstelephone users (approximately 42%). This is a 12% increase from 2000, when 30% of 9-1-1 calls were made with a wireless telephone(forty-five of one-hundred and fifty million calls). In Connecticut,the use of wireless telephones for calling 9-1-1 is even more pronounced, with nearly 63% being wireless in 2007.

If you call 9-1-1 on a cell phone, your location may not automatically display,as it does when calling from most home/business phones.Be Prepared to tell the 9-1-1 Call taker…• The location of the emergency - EVEN IN AN AREA THAT HAS LOCATION TECHNOLOGY(Address, street intersection, landmarks, city, county, mile marker, etc.)• Your cell phone number• What the emergency is and what type of assistance is needed(Source: www.nena.org)

IMPORTANT TIP

!!Phase 0 - wireless call connects to a Public Safety Answering Point(PSAP). No callback number or location information. Phase I - For E9-1-1 Phase I, the FCC requires the wireless carriersto deliver to the appropriate PSAP the telephone number of thehandset originating the 9-1-1 call (callback number) and thelocation of the cell site/ sector receiving the 9-1-1 call. Phase II - For E9-1-1 Phase II, the FCC requires the wireless carriersdeliver to the appropriate PSAP the telephone number of thehandset originating the 9-1-1 call and the latitude and longitude ofthe call. The accuracy requirement imposed on the wirelesscarriers by the FCC varies depending on the location technologyused by the wireless carrier. (Source: www.nena.org)

What are wireless telephones?Wireless telephones are hand-held phones with built-in antennas, often called cell, mobile,or PCS phones.How do they work?When you talk into a wireless telephone, it picks up your voice and converts the sound toradio frequency energy (or radio waves). The radio waves travel through the air until theyreach a receiver at a nearby base station (aka cell tower). The base station then sendsyour call through the telephone network until it reaches the person you are calling.When you receive a call on your wireless telephone, the message travels through thetelephone network until it reaches a base station close to your wireless phone. Then thebase station sends out radio waves that are detected by a receiver in your telephone,where the signals are changed back into the sound of a voice.(Source: www.fcc.gov)

WIRELESS 101

WIRELESS PERCENTAGES BY PSAPThe maps below show the percentage of wireless calls received byeach of Connecticut's 107 call centers (called Public SafetyAnswering Points, or PSAPs) in 2002 and 2007. The majority of thesewireless 9-1-1 calls are received by the State Police, Regional andmajor urban PSAPs, who all handle a good deal of 9-1-1 calls fromdrivers. For example, State Police Troop G, who patrols I-95 betweenGreenwich and Branford, had the highest number of wireless9-1-1 calls in 2007, with roughly 245,000, or over 17% of all wirelesscalls that year.
