NEW T-MOBILE DEPLOYMENTS CONFIRM E-911 TECHNOLOGY MEETS KEY 2002 ACCURACY MILESTONE

- results driven by unique GSM industry-wide collaboration - industry groups drive to fulfil FCC E-911 mandate - world first GSM location-enabled handset commercial availability

OFFICIAL operator results filed today by wireless operator T-Mobile show E-OTD location technology complied fully with this year's FCC (Federal Communications Commission) E-911 mandate - and reveal a unique GSM industry-wide commitment to meeting the 2003 requirements.

Cambridge Positioning Systems Ltd (CPS), which has developed E-OTD as the standardised GSM location solution, welcomed the filing which follows major network deployments involving network equipment and handset vendors in several US states.

The filing, which includes the most detailed results for any US location technology trial, highlights:

-   results from T-Mobile/Nortel deployment of 96m 67 per cent of the time/208m 95 per cent of the time - fully in line with FCC 2002 requirements for 100m/67 and 300m/95 per cent
-   results of Cingular/Ericsson deployment showing 90 meters/67 per cent of the time and 243 meters/95 per cent
-   the world's first E-OTD enabled handsets now in stores
-   unique vendor community - Ericsson, Nokia, Nortel Networks, Siemens and CPS - joint commitment to meeting FCC E-911 accuracy requirements
-   handset vendors - Motorola, NEC, Nokia, Panasonic, Samsung, Siemens, Sony Ericsson - create joint E-OTD handset working group

The report states: "The accuracy results from the E-OTD deployments are very encouraging...T-Mobile continues to believe that E-OTD represents the quickest path to full compliance with the (FCC) Phase II requirements for GSM."

It also includes details of an organisation - the Joint Industry Working Group - that has brought together senior management and technical expertise from global vendors Ericsson, Siemens, Nortel Networks, Nokia and Cambridge Positioning Systems. Up to 1,000 engineering and technical staff from these companies are currently working on E-OTD.

A second group, involving major handset manufacturers has also been formed, the filing discloses, in order to further progress E-OTD handset implementation.

The groups' objective is to provide an end-to-end approach to the delivery of the technology involving infrastructure, terminals and network design. This will involve the sharing of expertise and information drawn from system deployments in six US locations. Primarily, the industry-wide group will focus on ensuring the technology meets the industry requirements.

CPS Chief Executive Chris Wade said: "The whole GSM vendor community is behind E-OTD and it is this unique collaboration and commitment which has helped deliver these results. The imminent availability of commercial E-OTD handsets is also a powerful signal that the technology is meeting FCC requirements."

Today's filing follows two previous FCC submissions - from Washington and Houston - which also showed E-OTD performing in line with mandated accuracy guidelines.

FOR INFORMATION:

Cambridge Positioning Systems

Cambridge Positioning Systems Limited (CPS) develops and licenses its Cursor(TM) E-OTD (Enhanced Observed Time Difference) system to handset manufacturers and network equipment vendors. Cursor(TM) delivers high accuracy mobile location technology for GSM networks, with even greater accuracy predicted on 3G networks. CPS has conducted successful trials of the Cursor(TM) system in the UK, North America, Asia Pacific and Europe.

From October 2001 in the US, the Federal Communications Commission has mandated that all calls from mobile phones to emergency services be accompanied by highly accurate information about the location of a caller. This ruling known as E-911 will provide significant opportunities for CPS' highly accurate location technology as E-OTD emerges as the preferred choice to fulfil the FCC's regulation.
