Question

Which among the following is required for effective use of spectrum in an unlicensed spectrum band?

(a) Spectrum sharing algorithms

(b) Scheduling algorithms

(c) Planning algorithms

(d) Decision-making algorithms

I got this question in a national level competition.

The above asked question is from The xG Network Architecture in portion Next Generation Wireless Network of Cognitive Radio

Answer 1

The correct answer is:

(a) Spectrum sharing algorithms

Explanation:

In an unlicensed spectrum band, multiple users (both primary and secondary) can share the same frequency band. To ensure efficient and interference-free operation, especially in Cognitive Radio Networks (CRN), spectrum sharing algorithms are required. These algorithms enable the dynamic allocation and management of spectrum resources between licensed (primary) and unlicensed (secondary) users, ensuring that secondary users can opportunistically use the spectrum when it is not being used by primary users.

• Spectrum sharing algorithms help manage interference, avoid congestion, and ensure fair access to the spectrum in unlicensed bands, making them essential for the effective use of the spectrum.

While scheduling, planning, and decision-making algorithms are important in network operation, spectrum sharing algorithms are specifically designed to handle the efficient and fair use of unlicensed spectrum.
