|R&S Announces Single-Instrument
Solution For Mobile WiMAX Production Testing
Commercial WiMAX Deployment,
Wireless Technology Award
Rohde & Schwarz
October 3, 2007
Chicago, IL -- Rohde & Schwarz (R&S) introduced the R&S CMW270, an
“all-in-one” solution for WiMAX mobile station and customer premise
equipment testing in compliance with the 802.16e-2005 standard and the
WiMAX Forum Mobile System Profiles. The R&S CMW270 functions in either
non-signaling or signaling mode and is optimized for high speed
production, service, and quality assurance testing.
|The R&S CMW270 combines
signal generation and signal analysis capabilities in a single
instrument, and provides real-time WiMAX communication along with
physical layer and MAC layer observation. The instrument is designed to
seamlessly integrate base station emulation for signaling mode
measurements at minimal additional cost, which Rohde & Schwarz will make
available for the R&S CMW270 at a later date. In signaling mode, the R&S
CMW270 will be able to evaluate the behavior of a component or subsystem
under actual WiMAX operating conditions, eliminating the need for a
WiMAX base station as a reference. It also includes a general-purpose RF
signal generator and RF power meter.
In non-signaling mode, the R&S CMW270 enables calibration of mobile
WiMAX transmitters and receivers and measures receive characteristics.
It has comprehensive measurement functions for verification including RF
power, EVM, ACPR, spectrum mask, center frequency error, I/Q
constellation, crest factor, and spectrum flatness. The measurement
speed of the R&S CMW270 is up to ten times faster than that of existing
test solutions, which significantly increases throughput in the
production of WiMAX chipsets and mobile stations.
Since Rohde & Schwarz cooperated with chipset manufacturers at an early
stage, the R&S CMW270 is already adapted to market-leading WiMAX
chipsets reducing the adaptation effort in mobile station production.
Additional benefits include the low purchase price, the flexible
upgrades and selftest functionality.
The WiMAX tester from Rohde & Schwarz is ready for future expansions of
the WiMAX standard. It covers the frequency range from 100 MHz to 6 GHz
and supports all RF profiles defined by the WiMAX Forum. The R&S CMW270
tester for non-signaling mobile WiMAX measurements is available now from
Rohde & Schwarz.
