Methods presented above, based on signal propagation time measurement (U-TDOA, E-OTD
OTDOA) can be implemented by installing specific hardware and software on provider's side.
The synchronization-based E-OTD
location system can be likened to the satellite-based Global Positioning System, but using terrestrial installations and frequencies.
Than Conventional E-OTD
, Does Not Need Idle Period -- Down Link (IP-DL), and
Cambridge Positioning Systems Limited (CPS), the world's leading provider of mobile location technology systems, announced at the company's annual Industry Analyst Meetings that E-OTD
(Enhanced Observed Time Difference) has now been selected by all major US GSM mobile operators as their technology of choice for compliance with the impending US emergency services legislation, known as E911.
Based upon a Siemens MC45 tri-band GPRS module, the Mobile Data Card brings together GSM and GPRS data connectivity, as well as providing the authentication means for SIM managed Wi-Fi access and E-OTD
It also features E-OTD
(Enhanced Observed Time Difference) -- the ETSI's standard for location technology to meet the E-911 requirement and TeleTYpe (TTY) allowing automatic voice to data translation.
Cambridge Positioning Systems (CPS) today announced a technology cooperation agreement with Ericsson covering the integration of CPS' CURSOR technology as Intellectual Property building blocks to be deployed as part of the E-OTD
Cambridge Positioning Systems Ltd (CPS) today announced it is working with Intel Corporation to integrate its E-OTD
high accuracy location technology into a range of its products aimed at the wireless and handheld market segments.
Official operator results filed today by wireless operator T-Mobile show E-OTD
location technology complied fully with this year's U.
The methods provide an investment-secured evolutionary path to E-OTD
(enhanced observed time difference) and A-GPS (assisted global positioning system) covering GSM, 3G (WCDMA/EDGE) and All-IP RAN networks.
supports e911 emergency call requirements, as well as commercial applications like fleet management, community applications, and navigation and routing applications.
At CTIA's Wireless 2002 conference, Cambridge Positioning Systems (CPS) announced today a global licensing agreement to integrate its Cursor(TM) E-OTD
location-based technology with Nortel Networks Mobile Location Center.
