Guidance on Testing for Radio Access Equipment in Vietnam According to QCVN 65:2021/BTTTT

Testing for Radio Access Equipment in Vietnam according to QCVN 65:2021/BTTTT is a prerequisite for enterprises importing and manufacturing devices that use the 5 GHz frequency band before circulating their products on the Vietnamese market. In the context of rapidly increasing demand for wireless connectivity and increasingly dense frequency usage, the requirement for frequency resource management and network safety assurance has become urgent. To mitigate the risk of interference with priority services such as radar, the Ministry of Science and Technology has issued strict regulations.

I. The Situation of Radio Access Equipment Usage in Vietnam

5 GHz band radio access equipment (such as Access Points and Wi-Fi Routers) has become an indispensable part of the Internet network infrastructure in Vietnam, especially in urban areas. While the 2.4 GHz band frequently faces interference, the 5 GHz band provides higher speeds and better stability for users.

Currently, most modern organizations, enterprises, and households use dual-band or tri-band Wi-Fi devices that support 5 GHz to meet high-volume data transmission needs, such as high-resolution video streaming (4K video), online meetings, gaming, and real-time applications. This demonstrates the growing role of 5 GHz RLAN/WAS devices within internal connectivity systems.

Along with the sharp increase in usage, management requirements have also been tightened. According to Circular No. 29/2025/TT-BKHCN, 5 GHz band radio access equipment with an $EIRP$ of 60 mW or higher belongs to the List of Group 2 Products, making it mandatory to undergo Testing for Radio Access Equipment in Vietnam according to QCVN 65:2021/BTTTT and perform a declaration of conformity before market distribution.

Testing for Radio Access Equipment in Vietnam according to QCVN 65:2021/BTTTT is a critical step to assess the ability to meet emission limits, $EIRP$ levels, and safe operating conditions within the 5 GHz band. Manufacturing and importing enterprises must ensure products comply with regulations before circulation, especially when equipment has a power level of 60 mW or higher.

2. Technical Requirements

QCVN 65:2021/BTTTT stipulates requirements for bandwidth access to efficiently share bandwidth resources and limit the risk of interference with other radio systems. In the context of the increasing demand for 5 GHz band connectivity, Testing for Radio Access Equipment in Vietnam according to QCVN 65:2021/BTTTT helps assess the ability of equipment to meet technical requirements before being circulated on the market.

Accordingly, wireless local area network equipment (5 GHz band RLAN equipment) capable of operating in all or some of the frequency bands specified in this regulation must meet technical requirements regarding:

(1) Nominal Center Frequency: RLAN equipment usually operates on one or several fixed frequencies. The equipment is allowed to change its nominal operating frequency in case interference is detected or to avoid causing interference to other equipment and to meet the requirements of frequency planning;

(2) Nominal Channel Bandwidth and Occupied Channel Bandwidth: When the equipment transmits on multiple adjacent channels, the transmitted signal can be considered as from one channel with a nominal channel bandwidth equal to “n” times the individual nominal channel bandwidth, where “n” is the number of consecutive adjacent channels. When the equipment transmits on multiple non-adjacent channels, each used channel is required to comply with the regulations;

(3) RF Output Power, Transmit Power Control (TPC), and Power Density: The limits in the regulation may apply across the entire system and in any configuration, taking into account the antenna gain of the integrated antenna or dedicated antenna as well as additional gain (beamforming) in the case of smart antenna systems. The total RF output power of all channels within that component band must not exceed the limits defined in Table 2 and Table 3 of QCVN 65:2021/BTTTT;

(4) Transmitter Unwanted Emissions: The level of unwanted emissions outside the 5 GHz RLAN band must not exceed the levels specified in Table 4 of this regulation;

(5) Transmitter Unwanted Emissions within the 5 GHz RLAN Band: The band includes frequency ranges from 5 150 MHz to 5 350 MHz and from 5 470 MHz to 5 850 MHz. The power density (determined over a 1 MHz bandwidth) of the transmitter’s unwanted emissions within the 5 GHz RLAN band must not be greater than -30 dBm/MHz and the limit level determined by the spectrum mask in Figure 1 according to this regulation.

Figure 1 – Emission Spectrum Mask

(6) Receiver Spurious Emissions: Emissions on any frequency when the equipment is in receive mode; receiver spurious emissions must not exceed the limits specified in Table 5 of QCVN 65:2021/BTTTT;

(7) Dynamic Frequency Selection (DFS): The mechanism used by the equipment to automatically limit transmission and perform access to the operating channel. The DFS function is described under conditions where the equipment can transmit; transmission is allowed provided it is not prohibited by adaptivity functional requirements. There are two types of adaptive equipment: Frame-Based Equipment (FBE) and Load-Based Equipment (LBE);

(8) Receiver Blocking Characteristics: Receiver blocking is the equipment’s ability to receive a desired signal on the operating channel with a guaranteed quality level in the presence of unwanted signals (blocking signals) at the input at frequencies outside the bands specified in Table 1 of QCVN 65:2021/BTTTT. Quality is assessed via the Packet Error Rate (PER) with a limit of 10%. In special cases for other purposes, the manufacturer must declare the specific quality limit to be used.

Note:

Circular No. 29/2025/TT-BKHCN stipulates the suspension of technical requirements under extreme/critical conditions from July 1, 2025, until the end of December 15, 2026, for products and goods that are not Wi-Fi transceiver equipment (Wi-Fi Modems, Wi-Fi transmitters), HS code 8517.62.51, with integrated Wi-Fi functions.
The technical requirements of this Regulation apply within the environmental operating conditions of the equipment as declared by the manufacturer. The equipment must comply with all technical requirements of this regulation when operating within the boundary limits of the declared operating environmental conditions.
