SIMULATION OF INTERFERENCES IN MOBILE NEXT GENERATION ACCESS NETWORK - NGA

Original language description

This article examines formation and simulation of interferences in new licensed frequency within communication in NGA 4G LTE networks, which are source of disturbing of radio and television broadcasting. This also use for increase of awareness about interference problematics in access network. This article is dealing with sources of interference within licensed zones, its creation and also provides theoretical and applied possibilities of its technical solution between licensed zones. Article provides experimental verification of interference influence between access points and other possible devices working on close frequencies. Access points are equipped by technology of fourth generation. Basic of this experiment was created in program Matlab. Simulation demonstrates influence of interferences between access points on transmission quality. Significant parameter for evaluation of transmission quality was network permeability. The most important aim of this article was introduced reader with interferences in wireless networks, which are created by implementation of new devices into already functioning infrastructure. At the beginning were analyzed problems created in the Czech Republic and also in US. The main differences were found in the way of technology implementation on lower frequencies around 800 MHz and on upper frequencies around 2300 MHz. Lower frequencies are applied mostly in the Czech Republic and these type of frequencies shown weaknesses mainly in measurement of power signal DVB-T around access points LTE. Consequence of interferences were disturbances in receiving image and sound on television receiver in the Czech Republic. Similar problem between satelite radio and access points LTE was found also in US. Implementation of technology LTE led to similar consequences. Blackouts and weak radio signal were reported to local regulator. This reports after all were conducted into measurement and trials to mitigate the consequences of their implementation.
