A primer on E 9-1-1
e911 Around The Web
A quick search around the web revealed some updates of what the industry's leaders are doing to address
e911 issues and concerns.
Sirf --
SiRF Technology, Inc. develops and markets semiconductor and software products that are designed to enable location awareness in high-volume mobile consumer devices and commercial applications. The SiRFLoc architecture, with multi-mode, client-server capabilities, is designed for the wireless carrier deployment of GPS enabled location technology.
Lucent -- Xmarc, Inc. and Lucent Public Safety Systems recently
announced a complementary technology agreement to develop
PSMap(TM), a centrally based mapping service for wireless
E9-1-1.
PSMap will deliver reliable and accurate maps to the nation's
public safety call centers -- or Public Safety Answering Points
(PSAPs) -- assisting them in meeting the challenges of
responding to wireless E9-1-1 calls. Lucent Public Safety
Systems (LPSS) plans to offer this nationwide to public safety
call centers beginning in 2001.
Qualcomm --
-- QUALCOMM's gpsOne position location technology merges GPS satellite
and network information with highly sophisticated SnapTrack wireless location
technology to provide a high-availability solution that offers industry-leading accuracy
and performance. Using enhanced signal processing to overcome the limitations of other
GPS systems, especially in urban canyon and indoor environments, the gpsOne
solution exceeds the Federal Communications Commission's mandate requiring
wireless operators to provide the location of cellular 9-1-1 calls (E-911) to emergency
call centers.
SnapTrack --
SnapTrack utilizes a DSP software-based receiver solution in
conjunction with a location server. The location server processes
the satellite data and also performs "altitude aiding" against a
terrain elevation database for improved reliability and accuracy.
Utilizing SnapTrack technology within a handset minimally affects
the cost of the handset while improving location search accuracy
and performance. Carriers can deploy SnapTrack with no
modification to the existing network allowing them to meet E911
requirements with an acceptable future upgrade path. SnapTrack is a wholly owned subsidiary of QUALCOMM
Incorporated and is focused on integrating GPS and two-way wireless technologies.
Wireless Enhanced 9-1-1 from XYPoint --
XYPoint (who claims to be the largest provider of wireless E9-1-1 services in
the United States, with over three million subscribers located in
Alabama, Arizona, Colorado, Indiana, Louisiana, North Carolina,
Oregon, South Carolina, Tennessee, Texas, Virginia, and
Washington)
provides PSAP's with the cell site location, 10-digit call back number,
name of the wireless carrier, community or neighborhood call
origination, and emergency responder data critical to finding callers
in distress. Their platform includes
duplicate hardware and software configurations (for backing up
components in case of failure) residing at XYPOINT data centers in
Seattle, Washington, and Phoenix, Arizona.
SignalSoft --
SignalSoft Corp.'s Wireless 9-1-1 provides wireless network operators with a
simple solution for routing distressed wireless callers to emergency
assistance. The solution meets FCC phase I and II requirements,
automatically locating wireless callers and connecting them with the
correct Public Safety Answering Point.
NENA - National Emergency Number Association --
NENA is devoted to 9-1-1 exclusively and many
standards and process originate in their committees and workgroups. NENA has a dedicated
section titled "The Wireless 9-1-1 Web Page"... be sure to view the e911 checklist!
