Refarming Performance Analysis of Mobile Broadband System in Indonesia

Abstract

In telecommunication industries, the radio frequency spectrum is a limited natural resource that should be managed and utilized effectively and efficiently. One critical issue is operators possibly assigned in uncontiguous spectrum allocations that may affect their optimum services. This paper proposes the process and analysis of a refarming application process to rearrange radio frequency in the 800 and 900 MHz bands to become contiguous bands for Indonesia telecommunication systems. The systems performances are analyzed in two main parameters in telecommunication industries, namely the dropcall and Standalone Dedicated Control Channel (SDCCH) success rate. The refarming process results dropcall and SDSR average of less than 1% and greater than 95%, respectively. This value is influenced by the signal’s quality in each cluster, weather, and geographical conditions. Also, an analysis of the timing of refarming was carried out in each cluster, and the results of the CDF regression is close to the two-order polynomial regression. The mobile network operators that have had contiguous frequency allocation can upgrade their network and deliver better user experience with a higher mobile broadband capacity.
