Answer» Correct option is (a) Spectrum handoff latency is the time TAKEN to switch to a new FREQUENCY during handoff For explanation I WOULD say: Depending on the AVAILABLE spectrum, the OPERATIONAL frequency of the radio changes with time. When the radio changes its frequency of operation, the time taken for the new frequency to become operational is called spectrum handoff.
