NEW E-OTD DEVELOPMENT DELIVERS FCC E-911 2003 COMPLIANCE TODAY
- 45 metre/67% and 92m/95% performance achieved in network trials
- improvements part of major industry push to deliver higher accuracy
A MAJOR step towards enabling E-OTD technology meet the FCC’s E-911 accuracy
requirements for October 2003 is announced today by Cambridge Positioning
Systems Ltd (CPS).
The news follows an FCC filing earlier this week by T-Mobile and its network
equipment vendor partners that highlighted a range of new initiatives to
improve location accuracy. Confirming that the FCC’s October 2002 accuracy
requirements had now been met, T-Mobile also announced plans to speed E-OTD
deployment with new network upgrades and equipment rollouts.
As part of this industry-wide push, CPS today filed with the FCC details of
new E-OTD test results that show substantially improved location
accuracy. In field trials, carried out recently, CPS delivered accuracy
performance of 46m (67% of the time) and 92m (95%) - well within the FCC’s
October 2003 requirement of 50m/67% and 150m/95%.
The trial involved a citywide technology deployment including a range of
urban, suburban and rural environments. Similar techniques have been
evaluated in two US deployment sites confirming similar significant accuracy
improvements. Further trials will be carried out within the E-OTD Industry
Forum - made up of global equipment vendors - as part of an industry-wide
initiative to meet the FCC E-911 mandate.
CPS Chief Executive Chris Wade said: “With 2002 accuracy levels met, the
E-OTD industry is now focused on the 2003 requirement. It is clear we are
making real progress. The tremendous levels of activity are now translating
into agreed tangible improvements that will help us achieve our collective
goal.
“Our new initiative will now go into deployments in the US for further
testing. This is one of a number of technical initiatives the E-OTD industry
is working on. It again highlights the major benefits of a standardised
solution for GSM - we can move rapidly as an industry to make cost-effective
improvements which can be applied globally.”
About CPS:
Cambridge Positioning Systems Limited (CPS) is the key enabler for high
accuracy location in the GSM wireless world. Its innovative E-OTD (Enhanced
Observed Time Difference) technology allows network operators to develop new
services that improve the safety of their customers and deliver profitable
applications.
Regarded as the location standard for market, E-OTD (Enhanced Observed Time
Difference) uses sophisticated mathematical algorithms to determine a user’s
position. CPS has licensed this cost effective technology -deployed in both
the wireless network and the mobile device - to leading global vendors for
integration into their network infrastructure products.
Technology trials and deployments are currently underway in the US, Europe
and the Asia Pacific region.
