Spirent(R) Communications Introduces an Integrated Solution for New CTIA A-GPS
over the Air Test Standard

Spirent ULTS Now Supported by ETS-Lindgren's EMQuest(TM) Antenna Measurement
Software

SUNNYVALE, Calif., March 24 /PRNewswire/ -- Spirent Communications plc (LSE:
SPT), a global leader in mobile device, application and wireless network
testing, today announced that ETS-Lindgren's EMQuest(TM) Antenna Measurement
Software now supports Spirent's UMTS Location Test System (ULTS). ETS-Lindgren
is one of the world's leading manufacturers of enclosed Radio Frequency (RF)
chambers and antenna measurement solutions for wireless test applications.

This new capability will enable wireless device manufacturers to quickly and
easily add Spirent's market-leading A-GPS instrumentation to ETS-Lindgren's
over the air (OTA) wireless test solutions, streamlining efforts to meet
emerging standards for wireless device A-GPS performance. The combined
offering of Spirent's A-GPS instrumentation and ETS-Lindgren's OTA test
facilities, antennas, and EMQuest software provide wireless device
manufacturers with the ability to test their products in compliance with the
upcoming 3.0 release of the CTIA's Test Plan for Mobile Station Over the Air
Performance. The requirements of this new release will become mandatory at all
CTIA Authorized Test Labs that perform OTA testing.

"We are delighted that the Spirent ULTS solution is now supported by
ETS-Lindgren. It is a natural step to link Spirent's market leadership in
A-GPS testing with ETS-Lindgren's leadership in wireless OTA test solutions,"
said Ron Borsato, solutions architect at Spirent Communications, who also
chairs the CTIA's GPS OTA Subgroup. "The large percentage of CTIA Authorized
Test Labs that use ETS-Lindgren's OTA solutions for testing GSM and UMTS
devices now have a straightforward upgrade path to add A-GPS OTA support."

Poor GPS antenna performance often leads to a disappointing user experience of
location-based services (LBS) which can reflect negatively on operators'
revenues. 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, performance issues due to the
GPS antenna 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 Position Location Test System
(PLTS), launched into the CDMA market in 2001, the ULTS was 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 to design, test and
certify their LBS solutions.

Demonstrations of Spirent ULTS and other wireless device, application and
infrastructure testing solutions from Spirent will be held at Booth #744 at
CTIA Wireless 2009, April 1-3, Las Vegas, NV. For more information visit
