The government will be asked to set up a national 5G strategy committee, chaired by the prime minister, to accelerate 5G adoption in the country, says the National Broadcasting and Telecommunications Commission (NBTC).
Takorn Tantasith, the NBTC's secretary-general, said such a committee could help drive quicker 5G adoption in the country.
The NBTC has faced various problems in the past, including bringing back frequencies held by state agencies or the armed forces that have not yet used the spectra's full capacity.
"If this committee is established, such problems can be tackled much easier," said Mr Takorn.
He said the auction value for the 2600-megahertz band, meant to be used for 5G technology, will be appraised by the end of this month.
The NBTC assigned Thammasat and Chiang Mai universities and the Thailand Development Research Institute to complete the appraisal.
The spectrum auction is likely to be carried out early next year at the earliest, said Mr Takorn.
The 2600MHz spectrum has been held by state-owned broadcaster MCOT, which has to return 190MHz of unused bandwidth to the NBTC in exchange for compensation.
He is aware Vietnam, Singapore and Malaysia will commercially launch 5G service in June 2020 as Asean telecom regulators held a conference last week in Bangkok.
"This raised our concerns about investors possibly relocating to these countries, making Thailand lose an opportunity to push the economy forward," said Mr Takorn.
Last month the NBTC indicated there are two sets of multi-band ranges meant to cater to 5G technology that would be put on auction.
The first batch consists of 700MHz, 2600MHz and 26-28 gigahertz spectrum.
The other comprises the 3400-3600MHz and 1800MHz ranges.
