Bangkok’s 5G auction didn’t just raise money. It redrew the map of Thailand’s telecom industry.
The February 17 sale, run by the National Broadcasting and Telecommunications Commission, handed out 48 licenses across three spectrum bands. The final tally: 100.52 billion baht, or about US$3.2 billion. But the numbers tell only part of the story.
Advanced Info Service walked away with 23 licenses. That covers all three bands — 700MHz, 2600MHz, and 26GHz. True Move H Universal Communication Plc took 17, split between nine in the 2600MHz band and eight in the 26GHz band. State-run operators CAT Telecom Plc and TOT Plc, bidding for the first time, picked up six combined. Total Access Communication Plc, known as DTAC, grabbed two licenses in the high-band 26GHz range.
The price per license hit 1.95 billion baht. Payment terms vary by band. Winners in the 700MHz and 2600MHz bands get 10 years and seven years, respectively, to pay the government. Those who won 26GHz licenses must pay in full within 12 months.
This auction did not happen in a vacuum. Thailand’s telecom sector has been consolidating for years. The NBTC, under Secretary-General Takorn Tantasith, had pushed for this sale as a cornerstone of the country’s digital ambitions. The 5G rollout, expected commercially later this year, aims to lift a sector that has seen slowing growth in traditional voice and data services.
The timing matters. Thailand is competing with neighbors like Malaysia and Vietnam for investment in next-generation networks. A successful auction signals to foreign investors that the regulatory environment works. It also gives operators a clear path forward — they now know what spectrum they own and what they must pay.
State-run operators CAT and TOT entered the bidding for the first time. That marks a shift. Previously, they held spectrum without competitive auction. The NBTC forced them into the open market, a move that levels the playing field with private operators like Advanced Info Service and True Move.
The 700MHz band, in particular, carries weight. It offers better coverage over distance and through walls, making it ideal for rural deployment. The 2600MHz band provides a balance of speed and range. The 26GHz band, at the high end, delivers massive capacity over short distances — useful for dense urban areas and industrial applications.
DTAC’s strategy stands out. It only bid on the 26GHz band, taking two licenses. That suggests a focused approach on high-capacity urban hotspots rather than a nationwide network. Whether that pays off depends on how quickly demand for 5G services materializes in cities like Bangkok.
The auction raised more than the NBTC’s minimum expectations. That reflects genuine demand from operators, not just regulatory pressure. Each company calculated its own math — what spectrum was worth versus what it could earn from 5G services in the coming years.
Thailand’s digital sector now has a foundation. The NBTC has cleared the regulatory path. Operators have their licenses. The next step is building the networks and selling services to customers. That work starts now.
