Coverage and Capacity Prediction in Cellular Network

Cell breathing technique is commonly used in cellular network such as Wideband code division multiple Accesses (WCDMA) to overcome load congestion by expanding or shrinking the cell coverage. Cell breathing allows the available access point to reconfigure the cell boundaries by changing the transmitted power. In the design of cell in mobile communication systems, path loss prediction models play an important role. Coverage and capacity are sufficient issues in the planning process for cellular mobile network. Here we focus on the calculation of capacity and coverage for a Wideband code division multiple access (WCDMA) cell for Universal mobile telecommunication system (UMTS) network in different propagation environments. In these systems the power is the main shared resources for users. One of the fundamental characteristic of CDMA system is that the coverage range is intrinsically linked to the capacity of the system. The base station cell coverage may expand or shrink depending on the number of mobile station being served. The more traffic being carried by the cell, the smaller the coverage area of the cell becomes. The Cost231 Hata and Walfisch-Ikegami Models are used in this study to predict the coverage and comparative result is presented.
