Spirent Supports New CTIA A-GPS Over The Air (OTA) Test Standard with Integrated Solution

Spirent Communications, a global leader in mobile device, application and wireless network testing, today announced that ETS-Lindgren’s EMQuest™ 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

RGB Networks Overcomes IPTV Complexities with Advanced Video Test Solutions from Spirent

Spirent TestCenter

Spirent Communications plc (LSE: SPT), a global leader in network testing, today announced that RGB Networks, the leader in network video processing, selected the award-winning Spirent TestCenter™ platform to facilitate the testing of RGB’s IPTV solutions. Additionally, RGB chose the Spirent TestCenter Hypermetrics™ Application Performance module to conduct the industry’s highest performance Layer 4-7, security and vulnerability assessment tests.

The emergence of IP video solutions and services over traditional telco and cable networks and over the Internet through services such Netflix,, YouTube and others has increased level of complexity associated with testing related equipment. Many test systems, unable to accommodate the needs of equipment manufacturers, impact the ability to ship products on time. Fortunately, RGB Networks understood that Spirent could help to tackle these challenges.

Spirent’s solutions allow us to conduct tests in a realistic network and user environment with a unique mix of traffic while reducing the time associated with successfully completing such efforts, said Charles Corablis, vice president of Engineering, RGB Networks. Unlike other products, Spirent addresses port density, high performance and critical aspect of realism required to ensure the highest Quality of Experience (QoE) for IPTV services.

The high density, multi-core architecture of Spirent TestCenter Hypermetrics provides RGB Networks with scalability and performance along with the capability to reallocate processing power to conduct the complex testing associated with IPTV. The emphasis on performance and application realism rather than just port density enables test engineers to invest in a single solution for all their testing needs while reducing capital expenses and operating within the constraints of limited budgets.

While there are other products on the market, RGB Networks’ decision to use Spirent test equipment demonstrates the value and unsurpassed capabilities we bring to the table, said Ahmed Murad, general manager, Multimedia Applications Solutions Group at, Spirent Communications. By continuing to deliver the most complete set of offerings, we help enable companies such as RGB to introduce technologically advanced solutions that are not only reliable but rich in features and functionality.

Communications industry leaders also depend on multi-functional, comprehensive solutions from Spirent to help ensure that the multi-play networks and multi-technology platforms of tomorrow deliver the QoE which service providers demand today. Testing the converged network is a strategic imperative for service providers and network equipment manufacturers to reduce churn and increase revenue potential.

Spirent offers others modules for its TestCenter platform including the Hypermetrics Converged (CV) and Hypermetrics Converged Multi-play (CM). These modules, along with Hypermetrics AP, support a robust and scalable test platform with a flexible user experience for conducting end-to-end Layer 2-7 multi-play testing at gigabit or 10gigabit line rates. Demonstration of Spirent TestCenter family of solutions can be viewed at Booth #202 at IPTV World Forum, London, March 25 -27. For more information visit
