Why do we use millimeter wave?

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 .

Why 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.

What are small cell sites?

They are lower-power cell sites that are installed every few blocks, instead of miles apart . Small cell installation consists of small radio equipment and antennas about the size of a pizza box or backpack that can be placed on structures such as streetlights, the sides of buildings or poles.
