    FAQ

    • Does millimeter wave technology have any impact on the health of users?

      Current research and main conclusions show that millimeter wave signals are not harmful to human health. Millimeter wave signals are higher in frequency and lower in energy, so they are less likely to cause harm to the human body. In addition, the radiation power of 5G millimeter wave technology is very low, far below the limit value of international standards, and will not generate heat radiation.

    • What is millimeter wave?

      As the name suggests, millimeter waves are electromagnetic waves with a wavelength (λ) of about 1 millimeter (more precisely, 1 to 10 millimeters). By using the formula f = c/λ, where c is the speed of light (3E8 m/s), the wavelength can be converted into a frequency range of 30-300 GHz. The millimeter wave frequency band has been designated as the "extremely high frequency" (EHF) band by the International Telecommunication Union (ITU). The term "millimeter wave" is also commonly abbreviated as "mmWave".
