  1. Increased coverage

  2. Improved signal penetration

  3. Higher data rates and capacity

  4. Reduced latency


Correct Option: C
Explanation:

Higher frequency bands, also known as millimeter wave (mmWave) spectrum, provide significantly higher bandwidth, enabling much faster data rates and increased capacity.

Which spectrum allocation approach aims to provide flexible and dynamic spectrum usage for 5G networks?

  1. Licensed spectrum

  2. Unlicensed spectrum

  3. Shared spectrum

  4. Cognitive radio spectrum


Correct Option: C
Explanation:
