E-911 Rural Carrier Location Solutions
When a cell phone user is in an emergency situation
and dials 911, there’s little room for error.
They need to be accurately located regardless
of their environment or the mobile phone that
they're using.
Today, TruePosition’s wireless location
technology is being deployed nationwide in the
Cingular Wireless and T-Mobile networks as well
as several regional networks. It exceeds the FCC’s
E-911 Phase II accuracy requirements, and it works
consistently, in all environments and with all
cell phones. In addition, it provides a platform
for a wide range of applications for public and
personal safety.
Public Safety Applications
- Exceeds the FCC E-911 Phase II accuracy
requirements in virtually any environment
- Any phone, anywhere: including indoors
and in cities with tall buildings; able to
locate any current or future cell phone on
the market
- Being deployed nationwide in the U.S. with
large and small wireless operators including:
Cingular Wireless, T-Mobile, Viaero Wireless,
and Iowa Wireless
- Enables a wide range of public and personal
safety applications beyond E-911 such as personal
security or medical alerts, child tracking,
lone worker management, crash or stolen vehicle
notification or bulk emergency alerts
The need for Enhanced 911
Service
In the early 1990s, as mobile phone usage began
to increase, emergency service providers in the
United States realized that many of the people
who dialed 911 from wireless phones were unable
to accurately describe their location —
resulting in a delayed response.
In response to this growing problem, the Federal
Communications Commission issued the Enhanced
911, or E-911
mandate, requiring wireless carriers to implement
technology that automatically locates wireless
callers. TruePosition developed its wireless location
solutions to help U.S. wireless carriers fulfill
the mandate.
Exceeding Phase II of the E-911
Mandate Phase II of the E-911 mandate
requires that network-based wireless location
systems locate 67% of calls within 100 meters
and 95% of calls within 300 meters. TruePosition’s
Uplink Time Difference of Arrival (U-TDOA) wireless
location technology has exceeded these requirements
in extensive deployments conducted in varied environments
and with multiple air interfaces. Today, TruePosition’s
technology is being deployed nationwide in the
Cingular Wireless and T-Mobile networks. TruePosition
and the wireless operators are providing life-saving
location information which is available to millions
of users across the United States. In addition,
the technology is being deployed by smaller rural
carriers like Viaero Wireless and Iowa Wireless.
Enabling Public and Personal
Safety Applications
Due to the potentially grave nature of safety-related
services, it is absolutely critical to be able
to accurately locate the caller every time they
need assistance. TruePosition’s technology
not only meets the FCC’s location accuracy
requirements, but also works everywhere including
indoors and dense urban environments. In addition,
TruePosition’s technology extends these
safety-enhancing benefits to all wireless users — able
to locate any current or future cell phone on
the market.
- Exceeds E-911 Phase II accuracy requirements
- Works consistently in urban, suburban, and
rural environments
- Locates all current and future wireless phones
without modification
- Works with all wireless networks: AMPS, CDMA,
TDMA, and GSM
- Effectively supports E-911 and a wide range
of additional safety services
These and other functional advantages allow TruePosition’s
wireless location solutions to enable a wide range
of public and personal safety applications beyond
E-911 such as:
- Personal security or medical alerts
- Crash or stolen vehicle notification
