Question

Which among the following is a challenge for spectrum mobility in the time domain?

a.

QoS maintenance

b.

Cooperative sensing

c.

Interference temperature measurement

d.

Reconfiguration

Posted under Cognitive Radio

Answer: (a).QoS maintenance Explanation:xG networks change constantly in the wireless spectrum in accordance with the available spectrum band. The available spectrum bands tend to vary with time. Thus QoS maintenance becomes difficult. The radio should alter its position to meet the QoS requirements.
