Capacity Improvement and Congestion Control of WCDMA Network Using Dual Cell and Two Co-Siting Sectorization Technique
Publication Date : 23/06/2021
Presently, a good number of users with communication gadgets usable with second generation (2G) and third generation (3G) Wideband Code Division Multiple Access (WCDMA) accessible networks are prevalent especially in developing countries. These networks experience congestion, interferences and poor Quality of Service (QoS) due to the large number of users with limited available spectrum. Cell sectorization scheme of 3-sector (1200) commonly used in Base Transceiver Station (BTS) can be employed to improve the WCDMA 3G cellular network capacities with dual cell sectoring model of 3-sector 2-1200 applied to multi-band combiner strategy for co-siting multiple WCDMA networks. This model can further enhance the system capacity with less inter-cell and intra-cell interference and improved handoff. A Users Multiple Sector Sharing Algorithm (UMSSA) was introduced into the Dual cell model to provide seamless congestion control mechanism. Simulations was carried out using MATLAB and MPLAB(C++ Programming) to investigate the performance of the proposed scheme and the result showed that in a six co-channel channel cell; co-channel interference reduced from 2 to 1 with increased in capacity of at least 52% without increase in sectorization and handover factors as against existing cell sectoring models.
