WiMAX Protocol Test Solution

Tektronix Expands Capabilities Of Mobile WiMAX Protocol Test Solution

Other Topics: Open WiMAX Ecosystem, Wireless WiMAX Solution, Mobile WiMAX Test Set

February 16, 2007

Beaverton, OR -- Tektronix, Inc. announced the availability of two dedicated Mobile WiMAX test solutions: one for functional test and WiMAX infrastructure simulation, based on expanded capabilities to the G35-WiMAX solution; and one for monitoring purposes, based on the Tektronix Network and Service Analyzer (NSA) platform, which adds troubleshooting and performance analysis capabilities.

Introduced in October 2006, Tektronix’ G35-WiMAX solution enables accelerated time-to-market and development cost and time reduction through the monitoring and in-depth decoding of R1 and R6 interfaces. Tektronix completes the portfolio of functional test applications with the introduction of R1 and R3 simulation on the G35-WiMAX. High performance and complex monitoring requirements of stress tests, field trials, and real network deployments are met by the Mobile WiMAX multi-interface call trace and statistics on the NSA software and the proven Tektronix K18 portable probe form factor.
Tektronix’ customer Alcatel-Lucent is the company's first WiMAX communications infrastructure provider to use the G35-WiMAX solution in the development of its Mobile WiMAX network systems. “We are confident in Tektronix’ ability to enhance our Mobile WiMAX network solutions as we continue to help operators prepare for growth,” said Erwin Stegmaier, head of WiMAX development, Alcatel-Lucent.

“While mobile WiMAX technology is still at the beginning of its lifecycle, the demand for diagnostic tools is growing from both the manufacturer test labs where functional and interoperability tests are being performed and from network operators for their first field installations and support in pilot phase operations,” said Arif Kareem, Vice President, Network Diagnostics, Tektronix. “As a leader in mobile protocol testing, we are addressing our customers’ needs by giving them two very powerful platforms to support their Mobile WiMAX development and deployment efforts, while enabling such benefits as accelerated time-to-market and reduced development and integration costs. We believe first-to-market support of customers' new technologies and applications is our true differentiation.”

The G35-WiMAX solution currently provides protocol analysis tools, such as real-time decoding and advanced filtering of IEEE 802.16e R1 and vendor-proprietary R6 interfaces with both control and user plane monitoring and Bit Error Rate Test. The solution has been expanded to include R3 interface simulation, emulation and decoding capabilities. Adding the R3 interface enables end-to-end correlation of WiMAX ASN traffic – from the R1 to R6 to R3 interfaces. This saves time because problem areas and root causes within a complete test network are quickly identified. R3 simulation, including Access Network Gateways (ASN-GW) simulation to the Connectivity Service Network (CSN), CSN simulation to ASN-GW and Mobile Subscriber Stations (MSS) simulation to CSN, saves costs associated with functional tests through early identification of problems. Emulation of the CSN makes field tests possible before network deployment is complete.

Expanding the mobile WiMAX solution to Tektronix’ Network and Service Analyzer platform provides full visibility into lab and live network traffic through multi-interface traffic analysis tools, which isolate root causes of network and service problems. The WiMAX NSA supports end-to-end traffic analysis by correlating protocol traces on the R1 interface, multiple MSS and on the R6 and R3 interfaces. The multi-interface call trace for Mobile WiMAX saves time and effort in troubleshooting because calls of individual MSS are isolated. Full data capture is guaranteed under the most severe load conditions.

A key feature, Session Analyst, provides WiMAX control plane performance indicators to identify network problems that can be studied with other tools, such as call trace. Intermittent or non-recurring problems can also be identified. Session Analyst includes 802.16e MAC (Media Access Control) protocol counters and R6/R3 interface counters that display events on a time scale.
