Swisscom Mobile Improves Network Performance with Wavecall´s WaveSight Urban Propagation Prediction Tool

29/01/2008 - 10:20

Swisscom Mobile, part of the Swisscom Group, has successfully
applied WaveSight to improve performance of its UMTS network and HSDPA
throughput.

WaveSight has been successfully employed with an automatic
cellular tool to improve the performance of existing Swisscom Mobile
3G sites within the city of Basel, Switzerland, to enhance coverage
and service. The measured results showed an improvement in quality and
coverage area by as much as eight percent (8%) which can be translated
into a reduced, or delayed, requirement for additional sites whilst
increases the 3G traffic per user. The network changes were limited to
the remote adjustment of the antenna electrical tilt (RET) and the
transmitted power, during an overnight switchover. This ensured that
all the observed improvements resulted from the new changes.

There is potential for further optimization and revenue as the
national network expands, by further usage of the WaveSight tool to
keep the number of blocked and dropped calls to a minimum and, improve
coverage of trouble spots.

The success of applying WaveSight to Swisscom´s network was
enabled by a recent breakthrough in the tool´s computation
performance, whereby the processing speed was increased by over 10
times, allowing more sites to be included in the optimization process
without sacrificing the accuracy. Such results were achieved with no
need for costly and time-consuming drive test data.

Dr. Karim Rizk Founder and CEO of Wavecall, "It cannot be a better
reward to our pioneering work in the field of radio wave prediction
techniques to be able to deliver reliable solutions to our valued
customer Swisscom. We will continue to lead the way in providing
breakthroughs in radio wave prediction a critical field in wireless
network design and optimization. Swisscom is the natural partner to
first realize the impact of Wavecall´s technology"

Swisscom Mobile´s UMTS network covers about 90 per cent of the
populated area of Switzerland, and it is the first carrier in
Switzerland to roll out HSDPA. Thomas Vonlanthen, Head of Access
Technologies, Swisscom Mobile says: "We aspire to give our customers
the very best mobile coverage, offer them the latest technologies and
exceed their expectations. Ongoing investment in expanding, developing
and optimizing our services through products such as WaveSight ensure
we continue to deliver high standards of efficiency and quality of
service. We are delighted with the results achieved to date."

WaveSight can operate as plug-ins with most planning and
optimization tools. WaveSight is capable of optimizing the design of
GSM, WIMAX, UMTS and Broadcast TV networks.
