[wireless-regdb] 6GHz in Thailand

[James Clark]

Thailand approved use of 6Ghz band on 28th April 2023.

The regulatory authority in Thailand is the National Broadcasting and
Telecommunication Commission (NBTC) [1]. Their regulations have legal
effect when they are published in the Royal Gazette
(Ratchakitchanubeksa) [2].

The relevant announcement was published  in the Royal Gazette on 28th
April 2023 [3]. The technical content is on the 4th page of the PDF
labelled หน้า 1 จาก 3, in section 2.1. It approves the range 5.925 -
6.425GHz with EIRP 250mW, 12.5mW/MHz  inside buildings (ภายในอาคาร)
and 25mW, 1.25 mW/MHz inside and outside buildings
(ภายในอาคารและภายนอกอาคาร).

The date of effectivity is given on the first page of the PDF. The top
right of the page is the publication date ๒๘ เมษายน ๒๕๖๖ which is 28
April 2566 Buddhist Era (2023 CE). This line "ข้อ ๑
ประกาศนี้ให้ใช้บังคับตั้งแต่วันถัดจากวันประกาศในราชกิจจานุเบกษาเป็นต้นไป"
says that this announcement is effective from the date of publication
in the Royal Gazette.

There's an English language reference confirming this [4]. The WiFi
Alliance countries page [5] also lists Thailand as having adopted
5925-6425 MHz.

Please let me know if you need any further information.
