The university and related parties jointly conducted this experiment within its 5G-A Spectrum Joint Exploration project in its regulatory sandbox, running from late last year through September 2025.

Trairat Viriyasirikul, acting secretary-general of the National Broadcasting and Telecommunications Commission (NBTC), said the NBTC office allowed the university to set up the sandbox for testing new innovations and technologies, including allowing use of the upper band of the 6GHz frequency for the testing phase of the project.

Telecom industry operators support the 5.5G network being used in the project.
