Guidance on Testing for Short Range Devices in Vietnam According to QCVN 73:2013/BTTTT

Short range radio devices operating in the 25 MHz to 1 GHz frequency range are a group of devices commonly used in Vietnam for control, signal transmission, and monitoring applications. With stable wave propagation characteristics, good penetration capability, and low transmission power levels, this group of devices is widely deployed in both civil and industrial environments. Accordingly, enterprises are responsible for conducting Testing for Short Range Devices in Vietnam according to QCVN 73:2013/BTTTT to mitigate the risk of harmful interference.

I. Usage of short range radio devices under QCVN 73:2013/BTTTT in Vietnam

In Vietnam, the 25 MHz to 1 GHz frequency band is widely used for remote control devices in daily life and transportation. Typical applications include rolling door remotes and smart keys for motorcycles and cars; this is a device group with large quantities, widely distributed in residential and urban areas. Due to operating in an environment with a high density of devices, controlling emissions and frequency stability are important factors to avoid cross-interference between adjacent radio systems.

In the fields of transportation and industry, devices such as pressure monitoring systems and industrial IoT sensors using LoRa or Sigfox technology are also widely deployed. The rapid increase in these applications demonstrates the practical role of quality control for short range radio devices according to QCVN 73:2013/BTTTT, while simultaneously setting strict requirements for compliance with technical regulations to ensure frequency spectrum order during operation.

1. Scope of Application

According to Circular No. 29/2025/TT-BKHCN – The Circular providing the List of products and goods with the potential to cause unsafety in the field of information technology and telecommunications under the management responsibility of the Ministry of Science and Technology, short range radio devices are required to meet the technical requirements of QCVN 73:2013/BTTTT when falling under one of the following HS codes:

ORD	Product Name	HS Code	Product Description
1	Non-specific short-range radio transmitter and receiver equipment	8517.62.59 8517.62.69	Equipment with an external antenna connector and/or with an integrated antenna, used for transmitting or receiving voice, images, or other data forms; including equipment using active Near Field Communication (NFC) technology. Does not apply to the equipment mentioned in Section 4.1 of Appendix II.
2	Radio remote control equipment	8526.92.00	Equipment using radio waves to control models, or for industrial and civil control.
3	Radio Frequency Identification (RFID) equipment	8523.52.00 8523.59.10	Equipment using radio waves for automatic identification, tracking, and management of goods, people, animals, and other applications. The equipment consists of two separate blocks connected via a radio interface: – Radio transceiver equipment that stores information in the form of an electronic chip-bearing tag (RF tag), attached to the object to be identified; only applies to tags with a power source. Excludes Radio Frequency Identification (RFID) equipment mentioned in Section 4.2 of Appendix II of this Circular.
3	Radio Frequency Identification (RFID) equipment	8471.60.90	– Radio transceiver equipment (RF Reader) used to activate the radio tag and receive the tag’s information, transmitting it to the data processing system. Excludes Radio Frequency Identification (RFID) equipment mentioned in Section 4.2 of Appendix II of this Circular.

QCVN 73:2013/BTTTT specifically regulates short range radio devices with a transmission power level up to 500 mW, such as general short range radio devices, devices used in warning, identification, and radio positioning systems, remote control, telemetry, radio frequency identification devices, motion detection and warning devices, and the aforementioned types of radio equipment operating in the frequency bands from 25 MHz to 1 GHz must be tested according to this regulation.

2. Technical Requirements

Short Range Devices (SRD) operating in the 25 MHz to 1 GHz frequency range in Vietnam must meet the technical requirements specified in QCVN 73:2013/BTTTT, including: limits on transmission power, receiver sensitivity, signal quality, unwanted emissions, and regulations on frequency band use to ensure compatibility and prevent interference with other radio services.

Receivers used in short range radio equipment are divided into three categories. Each category has its own minimum reception requirements and technical specifications; these indicators depend on the selection of the receiver type used.

Type of Receiver	Assessment of receiver quality in terms of hazards to humans	Measurement methods and requirements for receivers
1	High-reliability short-range radio equipment; for example, systems serving human life (which can affect human health).	Adjacent channel selectivity Blocking Spurious response rejection Receiver spurious radiation
2	Medium-reliability short-range radio equipment, causing inconvenience to humans but which cannot be easily overcome by other measures.	Blocking Receiver spurious radiation
3	Standard-reliability short-range radio equipment, causing inconvenience to humans but which can be overcome by other measures (for example, manually).	Blocking Receiver spurious radiation

Note: In addition, the receiver must also meet requirements for sensitivity, the LBT (Listen Before Talk) threshold of the receiving equipment, and adjacent channel selectivity.

Transmitters used in short range radio equipment must meet requirements for frequency error, spread spectrum modulation, average power, effective radiated power, instantaneous power, adjacent channel power, modulation bandwidth, unwanted emissions in the spurious domain, frequency stability under voltage conditions, and duty cycle as specified in this QCVN 73:2013/BTTTT.

4.1. Regulations on Qualified Testing – Certification Units

Based on Article 5 of Consolidated Document No. 02/2020/VBHN-BTTTT – Regulations on conformity certification and declaration of conformity for specialized information technology and communications products and goods, the testing units serving certification and declaration of conformity are regulated as follows:

The testing unit serving conformity certification activities must be a designated or recognized testing unit.

The testing unit serving conformity declaration activities must be a designated or recognized testing unit, or a unit that has registered testing activities under Decree No. 107/2016/NĐ-CP dated July 1, 2016, of the Government, regulating business conditions for conformity assessment services.

Testing units are responsible before the Competent Authority for the accuracy of measurement and testing results. Measurement/testing results do not serve as a replacement for the Certificate of Conformity or the Declaration of Conformity.
