1.	What is spectrum mobility?(a) Spectrum mobility involves seamless channel switchover(b) Spectrum mobility involves sharing spectrum information among secondary users(c) Spectrum mobility involves managing spectrum sensing and spectrum sharing(d) Spectrum mobility involves sharing spectrum information between secondary users and xG base stationThe question was posed to me during an interview.The above asked question is from Next Generation Wireless Network in division Next Generation Wireless Network of Cognitive Radio
Answer» Right answer is (a) Spectrum MOBILITY involves seamless channel SWITCHOVER To explain I would say: Spectrum mobility involves performing seamless channel switchover while MAINTAINING the PERFORMANCE of current secondary user communication. Spectrum mobility is required when degradation of the current channel CONDITION is observed or when the primary user arrives in the licensed band.
