TEMPO.CO, Jakarta – Lecturer and researcher at Universitas Nahdlatul Ulama (UNU) Yogyakarta, I Nyoman Apraz Ramatryana, offers a way to optimize the performance of 6G networks to be more efficient and energy-friendly. A faculty member of UNU Yogyakarta's Information Technology Department, who is currently pursuing postdoctoral studies at Khalifa University, United Arab Emirates (UAE), revealed the optimization method through Frequency-Time Index Modulation Multiple Access (FT-IMMA) technology.
"Through this optimization method, the results make it possible for billions of devices to transmit data simultaneously without causing network congestion," said Apraz in his statement on Monday, August 3, 2026.
The sixth generation of telecommunication technology or 6G is set to officially launch in 2030. Apraz mentioned that advanced countries are competing to perfect this super-fast communication system.
Nyoman published his research results in the IEEE Transactions on Vehicular Technology, volume 74, issue 5 of 2025. His research focused on streamlining the data transmission procedures in transmitter systems.
"In simple terms, this research proposes a new method for many devices to transmit data simultaneously in 6G communication networks without queuing or requesting prior scheduling permission from the transmitter tower," said Apraz.
He explained that 6G technology is designed to be 100 times faster than 5G to support the integration of Artificial Intelligence (AI), Internet of Things (IoT), and the virtual world. However, its implementation is still overshadowed by significant challenges, such as the high cost of infrastructure, the limited range of high-frequency waves, and transmission obstacles hindered by physical buildings.
To overcome these obstacles, Apraz likened the data traffic in 6G telecommunication systems to vehicles passing through tollways. "Like tollways, previously vehicles (data) could only be regulated to enter based on lanes (frequency) or time (entry hours) separately," he said.
The FT-IMMA system's operation that he researched, according to Apraz, combines both into a two-dimensional system. "Thus, data can intelligently seep in by selecting a specific combination of frequency and time resources."
The two-dimensional frequency and time combination approach is the main novelty offered in his research. He claimed that this approach effectively saves spectrum wave usage and minimizes energy wastage during the transmission process.
"As a result, data transmission becomes much more efficient in terms of spectrum and energy, and is capable of reducing the risk of data collisions compared to conventional methods," said the IT Convergence Engineering doctoral graduate from Kumoh National Institute of Technology, South Korea.
The application of the FT-IMMA scheme is projected to have a significant impact on six strategic fields. Ranging from immersive communication, smart cities, industry 5.0, AI-based smart services to environmentally-friendly networks (sustainability & green network).
In the development of smart cities, Apraz said that this technology can be implemented in real-time railway signal systems and traffic lights to enhance public safety. "This can reduce congestion by 15-30 percent and improve public safety," said Apraz.
While in terms of environmental preservation, he mentioned that the use of this efficient network can support the monitoring of green areas to detect early forest damage. According to Apraz, the presence of this technology will actively contribute to preventing the risk of more severe environmental damage and addressing global climate issues in the future.
The need for an efficient network is becoming more urgent given the surge in the massive number of smart devices worldwide. According to him, based on DataReportal and Statista data, there are currently about 7.64 billion active smartphone units worldwide. A device population that is at risk of causing data traffic congestion and slowing down internet connections.
"The FT-IMMA system allows these devices to communicate seamlessly, as it significantly reduces network communication burden or the overhead that typically slows down connections," he explained.
