Which of the following are disadvantages of using drones on 4G communication networks?
A. Delivering flight control command is slow.
B. The signal strength is Strong when lower the 120 from the ground but the connection is easily lost when the height exceeds 120m.
C. The uplink data rate is low.
D. The drone height is not within the mail lobe of the ground station antenna. The air signals are in disarray. There is no primary coverage cell. Frequent handovers cause significant downlink interference for terminals.
