The National Broadcasting and Telecommunications Commission (NBTC) has said Thailand may be the first country in ASEAN to adopt 5G.
NBTC Secretary-General Takorn Tantasith said that the infrastructure is almost in place and that users in Thailand will be able to use 5G by the year 2020.
Secretary-General Takorn also announced that NBTC will begin the bidding process for the 2,600 megahertz frequency, with the auction set to begin later this year.
In 2018, there will be a further two auctions for the 850 and 1,800 megahertz spectrum, prior to Thailand transitioning to 5G in 2020.
In addition Secretary-General Takorn said with the emergence of 5G technology, Thailand will phase out 2G technology within the next two years. Thailand still has around 800,000 2G subscribers.
When 5G finally does arrive it promises internet speeds almost 100 times faster than the current 4G technology and is set to revolutionise technology, e-commerce and media.
In terms speed, 5G will enable users to transfer files at around 5.7 gigabit per second.
Earlier this month, Thai telecoms giant AIS announced it was at an advanced stage in testing 5G technology.
The company said it was the first in the world to achieve development of the 4G MIMO technology and brings AIS a step closer to rolling out its 5G service.
