METHODOLOGY OF UPGRADING THE TETRA COMMUNICATION SYSTEM
Abstract
The article proposes a method of modernization of the section of the October railway station Chudovo - station Gryadi, equipped with a trunking system TETRA standard. The technique is based on the developed mathematical model verified on the basis of full-scale measurements. The purpose of full-scale measurements was to find weak coverage areas and visualize the real values of the signal level on the coverage map. The model includes expressions for the calculation of TETRA network coverage based on the Okamura-Khat model adjusted for the specifics of train communication. On the basis of the developed recommendations, it was proposed to modernize the section of the station Chudovo - station Gryadi by installing a new base station.
