Question

Which among the following caused the shift of complexity management from networks to cognitive radio?

a.

Introduction of multiple bands in radio

b.

Introduction of multiple modes in radio

c.

Introduction of multiple bands and multiple modes in radio

d.

Elimination of multiple bands in radio

Posted under Cognitive Radio

Answer: (c).Introduction of multiple bands and multiple modes in radio Explanation:The transition from software defined radio to cognitive radio is due to the availability of resources and technology that allow the incorporation of awareness, adaptability, and cognition skills in the radio. For example, cellular networks manage the wireless protocols for the user but the emergence of cognitive radio with the capability of supporting multiple bands and modes shift the responsibility of protocol management towards the radio itself.
