4G MOBILE NETWORK SERVICE QUALITY ASSESSMENT

Abstract

This article analyzes the types of mobile radio communication systems and their performance characteristics, service areas, technological differences and interactions between them. Mobile radio communication systems (MRC) are divided into different classes, which differ in their tasks, service areas and the type of services provided to subscribers. According to the size of the service areas, the systems are divided into the following categories: satellite communication systems, cellular systems, professional mobile networks (PMR), and wireless telephony systems. Each system is distinguished by its own characteristics and services, for example, satellite systems have global coverage, while PMR systems have more short-term calls and group calls. New generations of mobile communications, including LTE and WiMAX technologies, are also analyzed separately in the article. These technologies provide unique opportunities for increasing data transfer speed, improving service quality and implementing new features. LTE technology is a key enabler in increasing data rates, reducing latency, and improving integration with existing mobile systems. WiMAX plays a key role in providing broadband wireless connectivity, especially for high-speed Internet access in urban and rural areas.
