DC-RAN dynamic coverage methods to improve its performance

Abstract

Abstract In cellular networks, there are usually times when the density of the network changes at different times of the day, where congested areas attract a large demand for communications and data, which generates peak demand at specific times of the day, and vice versa also happens in the same area but at another time of the day, and in order to meet the needs of this changing demand the network must keep pace with changes in the density of the areas served. This can only be done if the network has a dynamic ability to handle the change in traffic density and demand intensity, which requires turning on/off a certain number of Remote Radio Heads (RRHs) that represent the Radio Frequency (RF) front end of the mobile network.  For the purpose of providing a reliable and acceptable telecommunications service to users and financially useful to network operators by rationing energy consumption and meeting the required needs, dynamic 5G networks can do this by relying on a Dynamic Cloud Radio Access Network (DC-RAN) that enables them to respond to demand variables by shifting several types of coverage cells into a single serviced area and stopping them when needed.
