Wi-Fi Router & Access Point NBTC Certification

Wi-Fi routers and access points sold in Thailand require NBTC certification for every frequency band they operate on. Most Wi-Fi bands qualify for SDoC (Supplier's Declaration of Conformity), but one configuration — devices operating in the 5725–5850 MHz band under the LTE application — requires Class A (Registration). Wi-Fi 6E products operating in the 6 GHz band (5925–6425 MHz) are certified under a separate standard and follow the SDoC path.

Certification Requirements

Wi-Fi routers and access points are certified under two NBTC applications: RLAN (Radio Local Area Network) for standard Wi-Fi, and RLAN WiFi 6E for 6 GHz operation. The 5725–5850 MHz band is the only band where certification class depends on the application: RLAN = SDoC; LTE = Class A.

The 5725–5850 MHz split explained: This band is the only Wi-Fi range where certification class depends on the application name, not transmit power. A device operating in this band under the RLAN application follows the SDoC path. If the device is classified under the LTE application in this same band — for example, a device that also supports LTE-U or LTE-LAA — Class A registration is required. Most standard Wi-Fi routers and access points without LTE functionality follow the SDoC path for this band.

What This Covers

This page covers Wi-Fi routers, access points, and similar RLAN equipment. Typical products include:

  • Consumer Wi-Fi routers (single-band, dual-band, tri-band)
  • Wi-Fi 6 (802.11ax) and Wi-Fi 6E routers
  • Enterprise and business access points
  • Mesh Wi-Fi systems
  • Outdoor wireless access points
  • Wireless range extenders and repeaters
Note on multi-radio devices: Smartphones, tablets, and laptops often include Wi-Fi alongside cellular connectivity (GSM, LTE, 5G NR). These combined products are certified under the cellular applications, which require Class B. See the Smartphone & Tablet or Cellular Equipment pages if your product includes cellular connectivity.

Required Documents

Document requirements differ by certification path. If your device requires Class A for any band, all Class A requirements apply to the combined application.

SDoC (RLAN and RLAN WiFi 6E bands)

  • Technical specification / datasheet with wireless communication details
  • Product photographs (exterior and label)
  • Test report from an accredited laboratory
  • Authorised declaration (manufacturer or authorised representative)

Class A (if device operates under LTE application at 5725–5850 MHz)

  • Technical specification / datasheet with wireless communication details
  • Product photographs (exterior and label)
  • Test report from an accredited laboratory outside Thailand
  • ISO/IEC 17025 accreditation certificate and laboratory scope
  • Authorised declaration (manufacturer or authorised representative)
Class A registration requires a local representative — a Thai juristic person holding a valid NBTC trade license and NBTC Supplier Code — to file on behalf of the overseas manufacturer. Zergo provides this as part of its certification service.

Estimated Timeline

SDoC (RLAN bands):Approximately 1 week from submission
Class A (LTE application):Approximately 5 weeks from submission
