WebbExplanation: Handoff is a switching technique which refers to the process of transferring an active call or data session from one cell in a cellular network to another. 13. Which one is not an advantage of using frequency reuse? a) Increased capacity b) Limited spectrum is required c) Same spectrum may be allocated to other network WebbOur proposal, termed Slow Frequency Hopping (SFH), exploits the frequency dependence of the two-ray model by switching channels (frequencies) to avoid nulls. The two-ray model is frequency dependent because the amplitude of the received signal is governed by the phase difference between the direct and indirect rays. WebbFrequency hopping is the periodic ch ange of transmission frequency and hopping happens over a frequency bandwidth which consists of numbers of channels. Channel which is used as a hopped channel is instan taneous bandwidth while the hopping spectrum is called total hopping bandwidth. chin shin yi
