Standard and Notification for 2.4 GHz/5 GHz
NBTC - The National Broadcasting and Telecommunications Commission of Thailand released standard NBTC TS 1035-2562 for Radiocommunication equipment using frequency 2.4 GHz and/or 5 GHz and NBTC Notification on the use of Short-Range Devices in the band 5GHz.
The standard replaces existing standard NTC TS 1012-2551 (Radio Local Area Network - RLAN).
2. Frequency of 5.725 - 5.850GHz:
2.1 Allows additional standard EN 302 502 for this frequency band (previously this test standard was not allowed).
2.2 Standard EN 300 440 is not accepted under this standard. Previous version of standard also do not have EN 300 440 but NBTC temporary accepted EN 300 440 test report in the past. Now NBTC does not accept EN 300 440. thus, for this band 5.725 - 5.850GHz, EN 302 502, FCC 15.247 or FCC 15.407. shall be provided.
2.3 Allows additional technology of LTE under private network or LTE under IMT. This is the same bands with LTE band 46 which has been opened previously. NBTC includes both technologies into this new standard.
Allows additional standard IEC 62368-1 (previously this standard only accepted TIS1561-2556 or IEC 60950-1). This is as same as previously announced NBTC TS 4001-2561 Electrical Safety which allowed IEC62368-1 on March 14, 2019. NBTC updated this test standard.
