Fulfillment Bandwidth Requirement Analysis of Access Transmission Cellular Network
Hari Haryono, Dadang Gunawan · 2020
The requirement for data services is currently increasing due to the use of smartphones for social media, online services, and internet access has increased significantly. Mobile Network Operators/MNOs try to balance these needs by increasing the deployment of transmitters/BTS (Base Transceiver Station) that support data services by implementing 4G technology. Following distribution of the BTS locations, it requires transmission between BTS to the core network. Without a transmission network with a sufficiently large capacity, the deployment of 4G BTS will be meaningless. This paper analyzes the selection of the best strategy that can be applied by Mobile Network Operators in deploying an access transmission network that connects 2G/3G/4G BTS to the core network. In this case the selected area is the Denpasar Bali cluster on the mobile network operator PT.XYZ. At the initial stage, bandwidth requirements are carried out by analyzing data traffic in Denpasar city, Bali, then with trend analysis the estimated bandwidth requirements are determined in the next few years and matched with the BTS configuration preferences at PT. XYZ. Fulfilling bandwidth needs is done by several scenarios. Furthermore, the calculation of TCO (Total Cost Ownership) and technical considerations are carried out on several alternative solution scenarios. Selection of the best scenario is done by the Rank Order Method (ROC), Reciprocal Methods (RR), Rank Sum Method (RS) and Equal Weight Methods (EW). The best scenario resulted from the analysis in this paper is “deployment microwave solution (upgrade capacity) and new optical fiber Hub”.
