EFFICIENCY OF COMPUTER MEANS FOR AUTOMATIC ANTENNAS DIRECTION IN WIRELESS DATA TRANSMISSION SYSTEMS

Abstract

Abstract.  Modern telecommunication systems have gained considerable popularity thanks, first of all, to effective means of information transmission. However, regardless of the method of information transmission, the effectiveness of any system can be limited by the maximum speed and range of this transmission. Also, the effectiveness and feasibility of using, for example, wireless data transmission systems depends on the terrain, speed of deployment, economic indicators and duration of use. In wireless data transmission systems, directional antennas are used in receivers (transmitters), which must be deployed to establish a communication channel by directing the signal to the source (receiver).    But the automatic antenna pointing process has a significant impact on the speed of deployment of such wireless data transmission systems with directional antennas. Increasing the efficiency of the means of auto-positioning of antennas is achieved due to the newly proposed structural organization of them, improved algorithms for controlling the direction of the antenna and the use of a modern element-component base. An analysis and comparison of the experimental results of the proposed solution for wireless data transmission systems was carried out.

Also, the structure of the automatic antenna direction system was proposed, a working prototype was implemented, the control software was created and its functioning was tested according to the developed algorithms. The broad capabilities of the modern element-component base for the implementation of equipment for automatic antenna pointing are demonstrated. The analysis of the test results of the created prototype showed the effectiveness of the proposed algorithms, which is achieved by combining them to obtain a guaranteed result. A scheme of application of these algorithms is proposed, the essence of which is that one algorithm should control the direction of the antenna, which will be approximate, and the other algorithm will perform exact positioning, that is, correct and complete the direction of the antenna.
