The National Broadcasting and Telecommunications Commission (NBTC) of Thailand published technical standard NBTC TS 1039-2566 on April 28, 2023. This technical standard is for telecommunication equipment and radiocommunication equipment using the frequency band 5925-6425 GHz.Approval and testing report requirements are outlined below. Requirements for 5.925-6.425GHz (e.g. Wifi 6E) approval
Required approval: Sdoc
Required test reports:
1) RF test report based on FCC Part 15.407 (ETSI EN is not acceptable): Below are required test clauses:
1.1 Maximum output power:
| Frequency (GHz) | Maximum e.i.r.p. output power (mW) | Maximum e.i.r.p. output power (dBm) | Application |
| 5.925-6.425 | 250 | 24 | Indoor |
| 25 | 14 | Indoor and outdoor |
Note: In case of approval outdoor equipment, test report with output power 250 mW e.i.r.p. will be rejected. NBTC require test reports with 25 mW e.i.r.p..
1.2 Maximum power spectral density:
| Frequency (GHz) | Maximum power spectral density (mW/MHz) | Maximum power spectral density (dBm/MHz) | Application |
| 5.925-6.425 | 12.5 | 11 | Indoor |
| 1.25 | 1 | Indoor and outdoor |
Remark: Access point with output power over 25 mW (e.i.r.p.) but not over 250 mW (e.i.r.p.) shall not be with battery powered source
2) EMF or SAR test report (For indoor/outdoor use with output power 25 mW, it can be exempted to EMF/SAR test report)
3) Electrical safety test report e.g. IEC60950-1 or IEC62368-1 or TIS 62368-1
For products that had been approved without 6GHz earlier under class A or class B (e.g. mobile phone with 4G/5G+wifi), if product will add wifi 6GHz, NBTC will require to get new type approval certificate and model number must be changed differently from original model number. For products that had been approved without 6GHz earlier under Sdoc (e.g. Wifi with 2.4, 5GHz), if product will add wifi 6GHz, NBTC will require to get new Sdoc and model number can remain as original model number.
