Calculating the Possibility of Data Transmission in Trunking Communication Systems

Abstract

In the present article, a calculation of a radio-relay communication line has been carried out in order to determine the operability of the selected location of the radio-relay communication on the designed route to ensure the required quality of communication. The classification of radio communication systems and, specifically, trunking communication systems (TCS) is given. The process of assessing the service area of TCS is considered. A comparative analysis of information transmission in analog and digital TCS has been carried out. The authors discuss advantages and disadvantages of communication channel access methods and describe a technology for creating three-dimensional schemes on plastics and flexible media, the advantage of which is the arrangement of elements at an angle, precise positioning of elements, freedom in choosing geometric shapes, and the possibility of its application in radio communication devices. The procedure for constructing a technological process using one of the most common technologies - LPKF-LDS®implemented in the laboratory of three-dimensional circuits on plastics and flexible media of the Institute of Radio Electronics and Informatics of MIREA-Russian Technological University, is considered. The classification of intervals of radio relay lines is given and the calculation of the Fresnel zone is carried out. The minimum suspension heights of base station antennas are calculated, at which the RRL interval would be open
