Question

What is the function of spectrum mobility?

(a) Detect spectrum holes

(b) Gather information about available spectrum bands

(c) Vacate spectrum band

(d) Monitor spectrum band

The question was posed to me in my homework.

Origin of the question is Next Generation Wireless Network topic in division Next Generation Wireless Network of Cognitive Radio

Answer 1

The correct answer is (c) Vacate spectrum band

Best explanation: The cognitive radio users only have temporary access to the unused spectrum in the licensed band. If the primary user demands access, the spectrum mobility function of the spectrum management framework intervenes and transfers the cognitive radio user to another vacant position.
