True Corporation (SET: TRUE) has enhanced the 5G experience to full performance by implementing Dynamic Spectrum Sharing (DSS) technology on the 2600 MHz spectrum band. The initial service boost in Thonglor, Bangkok, marks the beginning of a continuous nationwide expansion. DSS technology maximizes spectrum allocation efficiency through flexible, real-time management in high-density areas with heavy data usage, enabling optimal service delivery for both 5G and 4G on the 2600 MHz band. This network upgrade is part of the Network Modernization plan to support over 14.2 million 5G subscribers nationwide (as of Q1/2025) and deliver superior speed and performance for both TrueMove H and dtac customers.
Dynamic Spectrum Sharing (DSS) is an intelligent technology that enables automatic, real-time, and flexible service delivery for both 5G and 4G on the 2600 MHz spectrum band, proportioned according to actual consumer usage. This differs from conventional fixed-allocation approaches that require separate spectrum blocks for 5G and 4G, which can limit the full potential of the 2600 MHz band for 5G when some portions are reserved for 4G without the ability to adjust dynamically based on real usage.
The key benefit of DSS is based on its real-time spectrum allocation flexibility. For example, in situations where 5G users are densely concentrated in a particular area, DSS technology can allocate the entire 2600 MHz band for optimal 5G performance. However, if circumstances change and 4G users increase in the same area, the system will flexibly adjust the 2600 MHz spectrum proportion to accommodate increased 4G demand, responding to customer needs in real time. This ensures that spectrum allocation is optimized according to the usage demands of both 5G and 4G users at any given time.
Furthermore, True Corporation’s acquisition of 70 MHz of the 2300 MHz spectrum to enhance its spectrum portfolio enables the use of the 2300 MHz mid-band spectrum for 4G services, while preserving the full potential of the 2600 MHz band for 5G. As a result, both 5G and 4G users will experience superior network performance, going beyond previous limits.
True Corporation selected Thonglor as the first location for full-performance 5G service with DSS technology, as it is one of Bangkok’s high-potential neighborhoods, seamlessly integrating business, lifestyle, and urban living. It serves as an international experience hub, highly popular among young professionals, businesspeople, and expatriates.
Mr. Sigve Brekke, Group CEO of True Corporation Public Company Limited, along with a team of network engineers and specialists, conducted an on-site inspection in Thonglor to test and monitor the use of 5G with DSS technology firsthand, ahead of True Corporation’s continued expansion and upgrade of both high-performance 5G and 4G networks to targeted locations across Thailand.
