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. |
