Performance Study of Uplink and Downlink of Macro Cells

Abstract

A Radio Access Network (RAN) is the major part of a mobile telecommunication system. In a RAN, radio sites provide radio access and coordinate management of resources across the radio sites. This Radio Access Network distributed over land areas called cells, each served by at least one fixed-location transceiver, known base station. In a cellular network, each cell uses a different set of frequencies which are known as uplink and downlink. The performance of Uplink and Downlink parameters of RAN in macro cell nodes and the number of users with traffic activity are analyzed and presented in this project. It especially focused on the study of the performance and analysis of path loss and noise ratio of the RANs. Traditional networks (2G, 3G, and 4G technology) are considered for data collection and simulation. The TEMS and QualiPoc software are used for Uplink and Downlink utilizations data collection and Microsoft Excel is used to present the graph and trending. Finally, this project is established about cell performance parameter of BTS and UL/DL performance of macro cell based on radio access network. The comparison of systems with cell range expansion (CRE) in the classic downlink is based on SNR. CRE not only helps to offload users from macro but also improves UL service. Instead of an aggregated throughput analysis, a detailed classification of users is performed to figure out the causes of users’ gain or loss after applying each strategy at the system level. UL adjustable cell offset appears to be an interesting strategy to allow for finer control of UL interference. In this project, the design-based study of the performance of the upper and lower links from Macro cell and Uplink-Downlink parameters.
