    - Spirent ULTS and PLTS Now Supported by SATIMO's SAM(TM) Antenna 
Measurement Software



    Spirent Communications plc (http://www.spirent.com) (LSE: SPT), a global
leader in mobile device, application and wireless network testing, today
announced that SATIMO's (http://www.satimo.com) SAM(TM) Antenna Measurement
Software now supports Spirent's UMTS Location Test System (ULTS)
(http://www.spirent.com/go/ults) and CDMA Position Location Test System
(PLTS) (http://www.spirent.com/go/plts)for A-GPS Over-the-Air (OTA) testing.
SATIMO is a leading supplier of high speed-antenna measurement systems,
including multi-probe antenna measurement solutions for mobile
telecommunication equipment.

    The combined solution of Spirent's A-GPS test implementation and SATIMO's
multi-probe antenna measurement system advances the development and testing
of A-GPS enabled mobile devices in several important ways as it:


    
    - Extends the capability of SATIMO's existing cellular OTA solutions to
      include GPS antenna performance
    - Delivers greater accuracy and reliability to A-GPS testing
    - Provides support for multiple air interface technologies including GSM,
      W-CDMA and CDMA.
    - Enables the testing of A-GPS enabled devices in full compliance with
      the 3.0 release of the CTIA's Test Plan for Mobile Station Over-the-Air
      Performance which was published in early May.


    "Offering an integrated solution with SATIMO gives Spirent tremendous
leverage in supporting the segment of the market with the most advanced A-GPS
OTA testing needs," said Ron Borsato, solutions architect at Spirent
Communications, who also chairs the CTIA's GPS OTA Subgroup. "SATIMO has a
market-leading multi-probe antenna testing features that can take
measurements with multiple antennas almost simultaneously. This enables our
solution to be extended to customers looking to test a higher volume of
devices or to those who need advanced test capabilities beyond CTIA Test Plan
coverage."



    As highlighted in a recent Spirent white paper entitled "A-GPS
Over-the-Air Test Method: Business and Technology Implications," poor GPS
antenna performance often leads to a disappointing user experience of
location-based services (LBS) and can reflect negatively on an operator's
revenue. However, adding a GPS antenna to a densely-packed mobile device form
factor can be a major challenge. Because the industry's existing
certification standards for A-GPS do not include OTA testing, GPS antenna
performance issues are not always caught prior to commercial deployment. This
has led the CTIA to broaden the scope of its existing Test Plan for Mobile
Station Over-the-Air Performance to include A-GPS.



    Built upon the expertise gained from Spirent's PLTS which was introduced
into the CDMA market in 2001, the ULTS is the first commercially-available
UMTS A-GPS test system. Since then, most of the world's largest network
operators, together with all the major mobile device and A-GPS chipset
manufacturers, have relied on the Spirent ULTS and PLTS products to design,
test and certify their LBS solutions. For more information please visit
