From UPSC perspective, the following things are important :
Prelims level : Millimeter Spectrum
Mains level : Rolling out of 5G services in India
The DoT plans to auction the 24.75 – 27.25 gigahertz (GHz) spectrum in the 5G band in March-April 2020.
- The new spectrum under the 5G band called the ‘millimeter-wave bands’ is separate from the 8,300 megahertz (MHz).
- The millimeter-wave band or extremely high-frequency frequency spectrum is mainly designed for usage in airport security scanners, closed-circuit television, scientific research, machine-to-machine communication, and military fire control.
What’s so special with this MM spectrum?
- As the wavelength becomes smaller, the cell size becomes less, which is the footprint of the relay station. This will be used more by the industry.
- If we you already have fiber connection and want to reach houses, this will be through millimeter bands.
