NBTC Issued Guideline for Consideration of Radio Frequency for IMT Conformity Assessment

Recently, the National Broadcasting and Telecommunications Commission (NBTC) of Thailand have released a formal notification “NBTC Notification - Guideline for consideration of radio frequency for IMT conformity assessment issued”. This notice is the final decision to the previous announcement of concerning the suspension of Type Approvals for products supporting partial bands of LTE/5G NR Bands 28 and 41. (IMT: International Mobile Telecommunications)
In the notification, NBTC specify that WWAN user equipment supporting 2G/3G/4G/5GNR bands which are opened in Thailand must support full bands in accordance with either the NBTC Notification regarding IMT frequency plan or as per 3GPP standards. Therefore, NBTC will not accept Type Approval applications for WWAN User Equipment using partial bands in Thailand.
For products that support partial bands which have been approved previously, NBTC has verbally confirmed that their certificates are still valid, and NBTC will not withdraw impacted approval certificates. However, NBTC may request that certificate holders of equipment using partial bands ensure that the equipment displays information making the user of the equipment aware that partial bands only are supported. And it remains subject to confirmation by NBTC.
