| 25th November 2006 - Willtek Communications announced a new
option that is designed to speed up integration testing and
production of TD-SCDMA mobile phones. The TD-SCDMA Call Mode
Option complements the non-call mode option for the 4400 Mobile
Phone Tester Series. These products integrate all the functions
necessary to calibrate transmitter and receiver of the mobile
phone, perform functional tests, and carry out the final test
prior to shipment. Willtek’s updated TD-SCDMA product portfolio
will be presented to the public for the first time at the ITU
Telecom World 2006 exhibition in Hong Kong from 4 to 8 December.
The product will be available by end-December.
Says Matthias Weber, Director of Product Marketing at Willtek
Communications: “The call-mode option comes right in
time before the start of TD-SCDMA phone mass production. The
4400 Mobile Phone Tester with TD-SCDMA is the first reliable
test solution for production; it is not only cheaper but also
much faster than the rack and stack equipment currently being
used by integration teams.”
Weber explains: “You do not want testing to become the
bottleneck of your production. This is why proper integration
of test equipment into the production lines is so important.”
With many years of experience in test and integration, Willtek
has the hardware, software and know-how to help integrate
the 4400 into production lines. The support team in Shanghai
has already helped a number of customers in China, with backup
from the R&D team in the German headquarters.
The 4400 Mobile Phone Tester Series is the first true multi-format
cellular phone tester also embracing TD-SCDMA. Since Chinese
manufacturers produce phones for countries applying multiple
standards such as GSM, GPRS, EDGE, WCDMA, CDMA2000 and 1xEV-DO,
testers need to accommodate those standards, too. In addition
to this, the 4400 can easily be switched between different
2G and 3G wireless technologies. It is therefore possible
to test mobile phones of various standards in the same production
line.
Willtek was the first vendor of integrated test equipment
for mobile phones committing to the Chinese TD-SCDMA standard.
The 4400 with TD-SCDMA supports the call setup and all the
important transmitter and receiver measurements for validation,
functional testing and calibration of wireless devices. These
measurements include peak and average power, open and inner
loop power, error vector magnitude, frequency error, peak
code domain power, spectrum, constellation display, BER and
BLER. The 4400 also eases successful interoperability tests
because major signalling functions are based on the Datang
protocol stack, while other protocol parts have been developed
in cooperation with the Beijing University of Posts and Telecommunications
(BUPT).
The 4400 with the TD-SCDMA options forms a fast, accurate
and reliable test system for wireless devices such as mobile
phones, wireless PDAs and PC cards. With its fast power measurements,
production sites can use it to precisely align the phone’s
transmitter within very little time, increasing the production
throughput and the quality of the devices. With its outstanding
performance and price, the 4400 provides vendors with extremely
low total test cost per wireless device. As all major cellular
standards are available on the 4400 series, it drastically
reduces production downtime because one test station can easily
switch from one technology to another.
