Question

Which among the following statements is true about the wireless network without xG architecture?

(a) Existing wireless networks exhibit homogeneity in the spectrum policies and heterogeneity in the communication technologies

(b) Existing wireless networks exhibit heterogeneity in the spectrum policies and homogeneity in the communication technologies

(c) Existing wireless networks exhibit homogeneity in the spectrum policies and the communication technologies

(d) Existing wireless networks exhibit heterogeneity in the spectrum policies and the communication technologies

The question was posed to me during an interview.

This key question is from The xG Network Architecture in chapter Next Generation Wireless Network of Cognitive Radio

Answer 1

Correct choice is (d) Existing wireless networks exhibit heterogeneity in the spectrum policies and the communication technologies

The explanation is: The currently available wireless networks express heterogeneity in both spectrum policies and communication technologies. For the effective incorporation of communication protocols, a clearly defined xG architecture model is required.
