Question

Which among the following is not a goal of the DARPA NeXt Generation radio communication program?

(a) Dynamically redistribute allocated spectrum

(b) Sense spectrum automatically

(c) Expand communication bandwidth

(d) Select operating mode

I have been asked this question in semester exam.

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

Answer 1

The correct option is (c) Expand communication bandwidth

To explain I would say: The DARPA NeXt Generation radio communication program aims to develop a radio with technology that can dynamically redistribute the available spectrum in radio networks, thereby making the best use of available communication bandwidth. The spectrum should be sensed automatically. The selected operating mode should maximize the survivability of communication networks and reduce the amount of interference to other users of the spectrum.
