DOI №______
Abstract
The work is devoted to research on the distribution of radio signals in the conditions of the Solomyansky region in relation to LTE (4G) technology, as well as the effectiveness of technology implementation in order to increase the speed of information transmission. In the process of work, the calculation and analysis of the level of power of the radio signal at different heights of the device hanger receiver was made. The resulting graphs may be of practical importance for the operational assessment of the coverage area with the expansion of the communication network. In the process of work, the calculation and analysis of the level of power of the radio signal at different heights of the suspension of the receiving device was performed. The resulting graphs may be of practical importance for the operative assessment of the coverage area with the expansion of the communication network.
Comparison of the results obtained by calculation with the results of simulation of the level of radio signal with the help of the program Atoll showed that the calculated values have deviations from the results of simulation in the range of 3 - 5%.
The use of orthogonal frequency (OFDM) and spatial (MIMO) diversity, which are the most important areas in the development of mobile communication technologies of new generations, potentially ensures the approximation of their spectral efficiency. Calculation of network bandwidth for multimedia services allowed to determine the required number of base stations.
The analysis of speed tests in LTE networks showed that the increase in downlink speed was 130-500 times.
Keywords: high transmission speeds, network structure, orthogonal frequency division multiplexing, MIMO technology, radio signal strength, network bandwidth.
