Abstract

Here is an example of how the fourth generation of cellular networks is developing rapidly today. The traffic per subscriber is growing every month. Operators are forced to provide coverage and the necessary capacity by installing new base stations. Quality network planning can provide better network performance and reduce deployment and optimization costs. It is also important to use a planning and optimization tool to model network coverage and perform performance analysis. According to the results of many studies, the amount of data transmitted over wireless networks has been growing significantly recently. Buildings are obstacles to the signal over long distances, so for the same area in different types of terrain for quality coverage it is necessary to place a different number of base stations. In addition, it is necessary to take into account the peculiarities of the building, as signals from different base stations are an obstacle for each other. On the other hand, high population density requires a large network capacity to meet the needs for speed and number of simultaneously connected users. Traffic is projected to increase by 2024, due to the emergence of new video services and the growing popularity and involvement of the population in existing ones. LTE-Advanced provides the ability to deploy repeaters to increase network performance. In the context of cellular communication systems, an important aspect is radio network planning - the process of locating base stations, determining the frequency channels and radio parameters of a wireless communication system to provide sufficient coverage and connection capacity to ensure the required level of service quality. to the user. Coverage planning refers to a geographic area where the network must provide a signal with sufficient power to provide access to voice or packet services, and capacity planning determines the system’s ability to provide services to a given number of subscribers. The purpose of the article is to study the process of planning the fourth generation LTE network in terms of urban development, calculations and modeling of coverage.
