Guidance on EMC Testing for Broadband Data Transmission Radio Equipment in Vietnam According to QCVN 112:2017/BTTTT

Broadband data transmission radio equipment is being used increasingly commonly in Vietnam. These devices operate on shared frequency bands with high deployment density, posing a potential risk of mutual interference if technical controls are not strictly maintained. EMC Testing for Broadband Data Transmission Radio Equipment in Vietnam according to QCVN 112:2017/BTTTT is an important requirement to ensure that equipment operates stably and is compatible with the radio environment in Vietnam.

I. Status of broadband data transmission radio equipment usage in Vietnam

In Vietnam, broadband data transmission radio infrastructure is growing strongly in both the number of devices and the scale of deployment. From home access networks to systems serving urban areas and industrial parks, these devices have become the primary method of data connection, gradually replacing traditional wired connections at the final access layer. Along with that, bandwidth demand is constantly increasing to meet big data applications such as high-resolution video, remote learning, and remote working.

However, operating mainly on shared frequency bands such as 2.4 GHz, 5 GHz, and extending to 60 GHz is creating great pressure on the electromagnetic environment. The high density of devices, especially in urban areas, leads to mutual interference and degradation of service quality. Given the increasing complexity of the radio environment, state management is being tightened, requiring circulating devices to simultaneously meet regulations on radio emissions and electromagnetic compatibility.

Accordingly, EMC Testing for Broadband Data Transmission Radio Equipment in Vietnam according to QCVN 112:2017/BTTTT is not only a requirement for businesses to responsibly comply with regulations but has become a condition to ensure that devices can stably coexist in the radio space.
