Question

Q. Consider the following statements regarding radio frequency spectrum (which is simply referred to as spectrum):

Which of the above statements is/are correct?

• A. 1 only
• B. 1 and 2 only
• C. 2 and 3 only
• D. 1, 2 and 3

Answer 1

The correct option is D 1, 2 and 3

Explanation:

All statements are correct

• The radio frequency spectrum (which is simply referred to as spectrum) is only a comparatively small part of the electromagnetic spectrum, covering the range from 30 Hz to 300 GHz.
• Lower frequencies have less bandwidth capacity than higher frequencies. It means that signals that carry a lot of information (such as television, broadband, or mobile phones) are better placed in the higher frequency bands while simple radio (audio) signals can be carried by the low-frequency waves.
• Spectrum has been internationally accepted as a scarce, finite, and renewable natural resource that is susceptible to degradation in case of inefficient utilization
