Thailand NBTC Re-Defines Technical Standard NBTC TS 1039-2566！

Previously on April 28,2023, Thailand NBTC announced Technical Standard NBTC TS 1039-2566 which enables frequency 5.925-6.425GHz as perbelow table：

However, on August 24, 2023, NBTC has redefined the regulation to allow portable equipment to use output power on both LPI 250mW EIRP and VLP 25 mW EIRP, which means that, now mobile phone, tablet, and notebook PC, will be eligible to apply for NBTC certificate in both 250 and 25 mW EIRP.

For formal implementation, NBTC will take a month to complete their internal approval procedure. Please note that there will be no formal regulation released for this update because the formal regulation remains same, it is only NBTC changed their interpretation to their regulation.

Below will be new table of Indoor and Indoor/Outdoor equipment classifications：

For document requirements, below will be document requirements for approval of WiFi 6E equipment in order to use output power 25 and 250 mW EIRP：

- Product specification: must indicate only frequency within 5.925-6.425 GHz (cannot show 6.425-7.125 GHz frequency)

- Declaration letter from end product manufacturer: NBTC requires a declaration letter from end product manufacturer to state that a) frequency 6.425-7.125 GHz will be disabled by software b) product is intended to use for indoor (LPI mode) and indoor & outdoor (VLP mode) application.

- RF test reports: must appear only 5.925-6.425 GHz (cannot show 6.425-7.125 GHz frequency). RF test report shall contain test result on both LPI 250 mW EIRP output power and VLP 25 mW EIRP.

- SAR test reports: must appear only 5.925-6.425 GHz (cannot show 6.425-7.125 GHz frequency). SAR test report for LPI mode 250 mW EIRP will be required.

- Electrical safety test report.
