Multiple choice

Which of the following is a benefit of using higher frequency spectrum for 5G?

  1. Increased bandwidth

  2. Reduced latency

  3. Improved coverage

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Higher frequency spectrum provides more bandwidth, which allows for faster data speeds. It also reduces latency, which is the time it takes for data to travel from one point to another. Additionally, higher frequency spectrum can improve coverage, as it can penetrate buildings and other obstacles more easily than lower frequency spectrum.

Multiple choice

What is the maximum theoretical speed of 5G using millimeter wave spectrum?

  1. 10 Gbps

  2. 100 Gbps

  3. 1 Tbps

  4. 10 Tbps
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The maximum theoretical speed of 5G using millimeter wave spectrum is 10 Gbps. However, this speed is only achievable in ideal conditions and is likely to be much lower in real-world deployments.
