Abstract

The trunking radio system used in the Makassar - Pare-pare region utilizes DMR tier 3, an internationally recognized open standard from ETSI. The Makassar - Pare-Pare railway network is a recent route with certain areas lacking network coverage, posing safety risks for train travel. An analysis of trunking radio signal quality along this route has not been previously conducted. This study analyzes signal quality to compare DMR Tier 3 performance. The approach encompasses theoretical analysis via the link budget method, simulation using radio mobile software, and field measurements employing handheld transceivers (HT). Analysis results reveal an average RSSI calculation of -62.49 dBm, simulation at -62.61 dBm, and field measurement at -76.47 dBm. All RSSI values across 36 measurement points meet ETSI (-113 dBm) and TAIT (-119 dBm) standards. The difference between calculation and simulation is 1.01 dBm, favoring the calculation. The average RSSI difference between simulation and field measurement is 13.86 dBm, favoring the simulation. This research offers insights into DMR Tier 3 performance on the Makassar - Pare-Pare route, with theoretical calculations closely resembling field results. These findings are crucial for enhancing communication between train operators and the control center, ensuring the safety and security of train travel along the Makassar - Pare-Pare region.
