  2. Higher upload speeds
  3. Latency will decrease drastically. (Latency is the time taken by wireless devices to communicate with a wireless network).

5G operates on 3 different spectrum bands.

  1. Low-band spectrum – It offers great coverage area and wall penetration. Lower speed compared to other spectrum bands is its disadvantage.
  2. Mid-band spectrum – The advantage it provides over the low-band spectrum is, it provides faster speed and lower latency. However, building penetration is lower than  Low-band spectrum.
  3. High-band spectrum – It offers the highest speed, but the coverage area and building penetration are greatly compromised compared to other spectrums.

Who invented 5G?

Research and Development on the 5G network were done with great vigour in many countries like US, UK, South Korea, China, and Japan.
