BANDUNG, Telkom University – Telkom University students created an innovation tool to help communication networks in post-disaster areas keep running. This tool is called Transceiver Recover Extension (T-REX). So what makes this tool capable of being a solution in handling disasters in hard-to-reach areas?
Damage to telecommunications infrastructure can harm many parties, for example, rescue teams such as the National Search and Rescue Agency (BASARNAS) which have difficulty communicating in post-disaster areas.
“That’s what motivated us to make technological innovations for telecommunication network recovery in post-disaster areas using wireless communication networks,” said Dyan Ahadiansyah, a member of T-REX.
T-REX can be used as an emergency base station, so it can assist communication in post-disaster areas when the main (existing) base station has been destroyed or is no longer functioning. T-REX has two main features, namely as a cellular signal amplifier (repeater) and as a private cellular network.
T-REX is designed using software-defined radio which can make telecommunications network services comply with 3GPP standards. T-REX has an open registration system so that all sim cards from any operator can be connected to the T-REX network service as long as it is within the T-REX signal range.
This tool (T-REX) began to be made when the announcement of passing the Student Creativity Program (PKM) funding was around May 2021, at that time the process was carried out online and offline. Offline activities are carried out in the lab. AICOMS Telkom University under the direct guidance of Dr. eng. Khoirul Anwar.
This tool was developed by four students of the S1 Telecommunication Engineering study program, Faculty of Electrical Engineering, Telkom University, consisting of Dyan Ahadiansyah, Okzata Recy, Lia Suci Waliani, and (late) Harnanditya Mahendra.
“During the design period of this tool, we received full support in the form of facilities and equipment from the lab. AICOMS,” said Dyan.
This tool has been tested in the blank spot area or difficulty getting a cellular signal around the Ranca Bali area, Ciwidey, Kab. Bandung on 28-29 August 2021. The location was chosen because it can describe a disaster situation with limited cellular network access and limited power resources.
As a result, T-REX network services can function as a repeater or signal booster or provide private cellular network services. Based on the results of tests that have been carried out, the coverage area of ????the signal strengthening of the T-REX can reach 1.8 km.
“Telkom University supports a lot in preparation for the 2021 Student Creativity Program (PKM). Starting from making proposals to research presentation exercises, the student body always provides input and assistance to produce quality research products.”
