Spirent® Communications Enables Delivery of Reliable High Performance WiMAX Networks and Services

Spirent Landslide’s proven testing technology now accelerates WiMAX deployments.

SUNNYVALE, Calif.--(BUSINESS WIRE)--Spirent Communications (LSE:SPT), a global provider of performance analysis and service management solutions, today announced WiMAX testing capabilities on the Spirent Landslide test system. Built on an industry proven mobile packet core test platform, Spirent Landslide WiMAX Performance Test System provides equipment manufacturers and carriers the ability to deliver reliable next-generation wireless broadband networks and services.

WiMAX is rapidly emerging as the leading 4G networking technology with carriers such as Sprint and Clearwire expected to roll out services by early 2008. However, the deployment of successful WiMAX networks depends not only on addressing issues related to network capacity and interoperability, but validating the performance of network equipment. The need for comprehensive end-to-end network performance test solutions such as Spirent Landslide WiMAX performance test system is greater than ever.

"Spirent Landslide is assisting Bridgewater in conducting rigorous WiMAX conformance and quality assurance testing to help ensure that our solutions meet the high standards service providers require for WiMAX network launch," said Eamonn Garry, vice president of research and development for Bridgewater Systems.

For the first time network equipment vendors, service providers and mobile device manufacturers can ensure that the products, systems and services they deliver meet the quality of experience (QoE) expectation of wireless broadband service subscribers. The Spirent Landslide WiMAX performance test solution delivers a comprehensive set of features and functionality that enable WiMAX protocol and performance testing.

"In a market characterized by increased competition within the vendor and service provider community, Spirent is committed to providing high performance, automated solutions that enable customers to quickly and cost efficiently roll out new next generation networks and services," said Bill Burns, chief executive officer, Communications Group Spirent Communications plc. "The addition of the WiMAX test capability to the Spirent Landslide platform continues Spirent’s tradition of providing highly scalable, easy to use performance validating solutions that help accelerate the deployment of new technologies."

The Spirent Landslide WiMAX performance test system supports powerful real-world traffic generation and nodal emulation capabilities. This includes base station and mobile subscriber station emulation that provides user-defined control over all aspects of WiMAX core network performance testing. Furthermore, the test system is capable of testing the ASN-GW in a standalone configuration; the ASN-GW and CSN combined in an end-to-end configuration; or the CSN in a standalone configuration. In each case, Spirent Landslide emulates the devices that communicate with the system under test.

The Spirent Landslide WiMAX performance test system provides the most comprehensive set of measurements and capability available including WiMAX AAA and Data Protocols, per-session and aggregate measurements including latency, throughput, average and peak readouts and scales to meet, up to 32 test servers per system; up to 100,000 emulated MSS per test server; up to 1,000 emulated base stations per test server; and up to 1,000 attaches per second per test server.
