Millimeter-wave (mmW) frequencies (30–300 GHz) are being used for many applications in the modern world. These applications include,but not are limited to, radio astronomy, remote sensing, automotive radars, military applications, imaging, security screening, and telecommunications .
Read moreWhy is millimeter wave faster?
Comparatively, the maximum carrier frequency of the 4G-LTE band, 2 GHz, provides an available spectrum bandwidth of only 100 MHz. Therefore, using millimeter wave frequencies can easily increase the spectrum bandwidth by a factor of 10 , allowing for a massive increase in transmission speeds.
Read moreWhat is the main problem of millimeter waves?
There is one major drawback to millimeter waves, though—they can’t easily travel through buildings or obstacles and they can be absorbed by foliage and rain . That’s why 5G networks will likely augment traditional cellular towers with another new technology, called small cells.
Read moreWhat is the disadvantage of 5G mmWave?
Disadvantages of 5G mm wave Millimeter wave goes through different losses such as penetration, rain attenuation etc . This limits distance coverage requirement of mm wave in 5G based cellular mobile deployment. Moreover path loss at mm is proportional to square of the frequency.24 Kas 2019

In humans, MM-waves have penetrating effects including impacts on the brain, producing EEG changes and other neurological/neuropsychiatric changes, increases in apparent electromagnetic hypersensitivity and produce changes on ulcers and cardiac activity .
