Development of modules for calculation of radio coverage in an open-source environment

Planning cellular radio telecommunication systems is a complex problem, solved by numerous mathematical models, using various program tools. An open-source system, such as GRASS, enables free development and improvement of existing mathematical models as well as usage of other modules for data processing. We developed new modules for coverage calculation, based on mathematical models such as Okumura-Hata, 9999 model etc. The achievements are useful above all for improved planning of GSM, UMTS and WiMAX networks.

Development of simulation model for performance analysis of telecommunication network

Using OPNET Modeler Wireless Suite tool we have developed a simulation model for performance analysis and wireless protocol optimisation in cellular networks. The, which we used, provides high fidelity modeling, simulation, and analysis of a broad range of wireless networks. We used OPNET tool to test the throughput of Telekom access network in the part of Ljubljana region, generating the traffic caused by http, P2P, IPTV and VoD services.

Inovations in the field of self-organizing wireless networks

We have submitted to the US Patent and Trademark Office two patent applications related to management and control of self-organizing wireless networks. The first innovation describes the method with the capability to automatically adapt the base station parameter settings to the environment, while the second innovation determine an iterative procedure for the location of mobile station, based on the received signal strength and difference in time of arrival. Both innovations result from the cooperation with 4G Neuron and LTFE in the scope of the WiMAX pico base station project.
