Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Millimeter wave spectrum is used for short-range, high-speed communications in 5G networks. This is because millimeter wave spectrum has a very high frequency, which allows for very fast data speeds. However, millimeter wave spectrum also has a very short range, so it is not suitable for long-range communications.
