Radio propagation prediction vendor, Wavecall says that Swisscom Mobile has successfully applied its WaveSight application 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"
