1.Good security and confidentiality
Because millimeter wave propagation in the atmosphere is greatly attenuated by the absorption of oxygen, humidity, and rainfall, the point-to-point transmission distance is very short, 5g mmWave and beyond that distance the signal becomes very weak. This increases the difficulty of enemy eavesdropping and interference.
The narrow beam range and low subflap of millimeter wave further reduce the probability of interception.
2. High transmission quality
Due to the high frequency band, there are basically no interference sources and the electromagnetic spectrum is very clean, so the millimeter wave channel is very stable and reliable, and the code error rate can be maintained at 10-12 levels for a long time, comparable to the transmission quality of optical cables.
3. All-weather communication
Millimeter wave penetrates rainfall, dust, smoke and plasma better than atmospheric lasers and infrared. This gives millimeter wave communication better all-weather communication capability and ensures continuous and reliable operation.
4. Small component size
Millimeter wave components are much smaller than microwaves, so millimeter wave systems are easier to miniaturize.
With so many advantages, millimeter wave has undoubtedly become a dazzling jewel in the 5G era.

The 3.5GHz frequency spectrum, where modern 5G runs, enables greater capacity and less latency. For next-generation communication, established mmWave technology can be used to obtain even higher frequency. Massive capacity and even lower latency are made possible by combining 5G and mmWave to fully experience 5G.
Urban regions with high population densities are built for higher frequencies, such as the 5G mmWave band. To provide extensive coverage, mobile carriers combine high-band, mid-band, and low-band spectrum.
