    - Spirent Landslide compatible with all 4G mobile standards including 
LTE, WiMAX, HSPA, CDMA and UMTS



    Spirent Communications (http://www.spirent.com/) (LSE: SPT), a global 
provider of performance analysis and service assurance solutions, today 
announced the launch of Long Term Evolution (LTE) testing capabilities on its 
Spirent Landslide Mobile Packet Core Test Platform 
(www.spirent.com/go/landslide) making the solution the market's first 
performance testing tool compatible with all current wireless standards 
including fourth generation (4G) network infrastructure products and services. 
Spirent Landslide (http://www.spirent.com/go/landslide) allows customers to 
deploy mobile broadband networks and applications rapidly and 
cost-effectively with unparalleled confidence while serving the demanding 
needs of the next-generation subscribers.

    Spirent Landslide, offering Layer 4-7 testing, is capable of emulating
traffic from as many as 32,000 mobile base stations and 3.2 million
simultaneous users at 120 gigabits per second and creates 'real-life' test
conditions that help identify and resolve service issues prior to deployment.
This approach significantly improves time-to-market for new services, reduces
subscriber churn and increases the quality of experience (QoE) for
subscribers using next-generation applications.



    "The addition of these new wireless testing capabilities of Spirent
Landslide will enable service providers and network equipment manufacturers
to bring LTE deployments forward." said James Brunson, director of Converged
Network Solutions at Spirent Communications (http://www.spirent.com/). 
"Spirent Landslide allows carriers and vendors to conduct regression and 
application testing in as real world an environment as possible. This 
ultimately enables the rollout of robust and reliable infrastructure 
equipment and services which will exceed subscriber expectations once they 
go to market."



    With the addition of LTE testing capabilities, Spirent Landslide now
addresses all 4G standards such including WiMAX, HSPA, CDMA and UMTS. It also
allows network equipment manufacturers to test hand-offs between different
networks. This is crucial as it ensures subscribers have the smoothest and
most uninterrupted experience as possible and their mobile devices receive
signals from multiple network sources running on different standards.



    LTE is the upgrade path from existing 3G GSM networks and will spawn a
new generation of wireless services such as high definition TV, mobile video
conferencing and the streaming of music, gaming and video services. It is
vital that network equipment manufacturers and service providers are prepared
for this development and are able to launch compelling, functional and
profitable services which take full advantage of their investment in LTE.
Spirent Landslide with its services-centric approach to network testing
offers a solution that provides unmatched end-to-end application testing
across mobile packet data networks, providing true QoE measurements for the
key application services like Web browsing, file transfer, streaming voice
and video, and other next generation services. Additionally, with an IPSec
accelerator card, Spirent Landslide now supports increased throughput of
encrypted data.
