Question

Which among the following is not a requirement for multiple spectrum band transmission by xG user?

a.

Spectrum holes

b.

Compatibility with internal policies

c.

Contiguous spectrum band

d.

Compatibility with quality of service

Posted under Cognitive Radio

Answer: (c).Contiguous spectrum band Explanation:xG users can transmit packets on multiple spectrum bands provided the available spectrum meets the quality of service requirements and the spectrum policies required for communication. However it does not require the multiple spectrum bands to be contiguous. This exhibits a vast improvement in communication quality during the spectrum handoff.
