    - Spirent ULTS Now Supported by ETS-Lindgren's EMQuest(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 ETS-Lindgren's (http://www.ets-lindgren.com/) EMQuest(TM) 
Antenna Measurement Software now supports Spirent's UMTS Location Test System 
(ULTS) (http://www.spirent.com/go/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 
(http://www.spirent.com/news/events.cfm?id=527&media=7&ws=330&ss=187). For
