Five submit bid documents for spectrum licences 

They are True Move H Universal Communication Company Limited (TUC) of True Corp, dtac TriNet of Total Access Communication, Advanced Wireless Network (AWN) of Advanced Info Service (AIS), TOT and CAT Telecom.
NBTC secretary-general Takorn Tantasith said that NBTC is expected to gain Bt70 billion from the auction, which will be handed over to the state.
He estimated that the winning bidders would invest a total of Bt130 billion in 5G network rollout this year, followed by Bt200 billion next year.
The NBTC will auction three licences of the 700MHz, seven licences of 1800MHz, 19 licences of the 2,600MHz, and 27 licences of the 26GHz.

According to a dtac statement on Tuesday, the board of directors had mandated its subsidiary, dtac TriNet, to participate in the upcoming spectrum auction for relevant licences.
The upcoming multiband auction is an opportunity for dtac to further strengthen its spectrum portfolio towards its goal of "never stop improving its network experience", the statement said. 
The dtac team was led by chief executive officer Sharad Mehrotra.
Due to NBTC's stipulated "silent period", dtac will refrain from making any further comments regarding the auction.

Sarit Jinnasith, co-Group President of True Corp said: “The Board of Directors of True Move H Universal Communication Company Limited (TUC) has passed the resolution to approve TUC's participation in the auction".
To take part in the auction, the company had conducted a thorough valuation analysis as well as hired a third party consultant to conduct a feasibility study on each available frequency.
The company’s consideration was based on consumers’ demand, return on investment as well as values for all stakeholders. Conditions of the upcoming multiband spectrum auction are favourable. It provides a variety of spectrums and sufficient bandwidths for operators to select, more than what were offerred in previous auctions.
Having more bandwidths will further strengthen TrueMove H’s network superiority and secure its market leadership to serve the increasing amount of customers as well as the customers’ fast-growing data usage.
The board of TOT approved the state agency to enter the bid, in line with the policy of the Ministry of Digital Economy and Society that TOT upgrade the country's telecom infrastructure to boost its competitiveness.
January 4 was only day set for the submission of bid documents.

Share prices of telecom companies ended higher on Tuesday with True gaining 2.69 per cent to close at Bt3.82, AIS increasing 1.46 per cent to Bt208 and dtac climbing 1.70 per cent to Bt44.75.
