Perbandingan Penempatan Node B UMTS900 pada BTS Existing Menggunakan Fuzzy C-Means dan Fuzzy Subtractive Clustering

Abstract

This study conducted a comparison of the planning for the placement of UMTS900 Node B network on the existing BTS of one operator in the Malang area using the Fuzzy C-Means method. and Fuzzy Subtractive Clustering, which is expected to reduce the number of BTS towers and increase cost efficiency. So that we can find the appropriate method for placing Node B in order spread evenly from 5 districts in Malang City. The results showed that planning for the placement of Node B UMTS900 in 2019 required 15 Node B for urban areas and 2 for sub-urban areas spread over 5 sub-districts in Malang city. Node B is placed in 36 existing BTS based on Fuzzy C-Means and Fuzzy Subtractive Clustering methods. Fuzzy Subtractive Clustering resulted in a more even distribution of Node B placement in each of the 5 sub-districts in Malang city compared to Fuzzy C-Means. The parameters used for Fuzzy C-Means and Fuzzy Subtractive Clustering are the radius value and the ability of each BTS to accommodate users who in the calculation process are supported by the MATLAB application. Then the results of Node B placement are displayed using MapInfo.
