Question

Which among the following represents the scale of spectrum band likely to be accessed by software defined radio?

a.

800 MHz – 900 MHz

b.

800 MHz – 850 MHz

c.

30 MHz – 2.5 GHz

d.

30 MHz – 250 MHz

Posted under Cognitive Radio

Answer: (c).30 MHz – 2.5 GHz Explanation:The software defined radio desirably operates over a large range of frequencies that cover various bands of the spectrum. The radio should be capable of supporting various applications such as TV bands, air traffic control bands, industrial medical and scientific bands, etc. For example, 30 MHz – 2.5 GHz has a bandwidth of 2.47 GHz which is most suitable for the spectrum requirements of cognitive radio.
