We developed a software tool for coverage calculation, based on mathematical models such as Okumura-Hata, Walfish-Ikegami and model 9999. We added a module for coverage calculation based on Ray-tracing algorithm. The tool is suitable for improved planning of GSM, UMTS and WiMAX networks. It is used also by Mobitel. Modules enable upgrading, they do not depend on specific network, they are integrated in open-source environment GRASS and they are suitable for parallel, multi processor execution.
F.06 Development of a new product
COBISS.SI-ID: 23823399In the simulation environment OPNET we developed a modular simulation model of general access telecommunication network, which enables the analysis of added functionalities as well as the evaluation of the whole telecommunication network. With this simulation tool we successfully analysed and tested the introduction of new services such as Video on Demand (VoD) and Fast Channel Changing (FCC) in the network of Telekom Slovenia. We evaluated the throughput in the part of Telekom Slovenia network.
F.17 Transfer of existing technologies, know-how, methods and procedures into practice
COBISS.SI-ID: 24461863We designed flexible wireless sensor node for the development of sensor networks and evaluation of their performance. The node supports access to different analogue and digital sensor elements and application of different protocols for the communication between sensor nodes. We developed a sensor node and accompanying Java application in order to transmit and store measured data on a mobile user device. We are now adapting sensor nodes to the environmental monitoring applications.
F.08 Development and manufacture of a prototype
COBISS.SI-ID: 23961383We 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.
F.32 International patent
COBISS.SI-ID: 23790887Program team members are project leaders for several FP7 projects at the Jožef Stefan Institute ( FP7 AgroSense, FP7 IDEALIST2011, FP7 ACTIVE, 7.OP PlanetData, 7.OP BalkanGEONet), where they are workpackage leaders or members of scientific board and management board. They are also national representatives in the Management Committees of COST 2100, COST IC0802, COST IC0902 and COST IC0906 Actions. The result of participation in international projects is transfer of expert knowledge in the field of wireless communication systems in national environment.
