Question 7 Single choice

You are working in a logistics company. Your manager is telling you that automation is very important to create more opportunities for the company. His idea is to deliver parcels using drones. With this in mind, he asks you if a 4G network provides good connectivity for controlling the delivery drones.

How would you answer him and why?

  1. A

    Yes, 4G provides a connectivity network but, it is quite expensive. WIFI may be a preferable option.

  2. B

    No, a 4G network is not a good choice for drone control because big operators (with whom we cannot
    deal) mainly deliver it.

  3. C

    No, a 4G network cannot deliver the required connectivity. It is not able to guarantee the latency and reliability required for drone control.

  4. D

    Yes, the drone control application can be hosted in the cloud and the 4G network can provide the speed needed to reach the application and control the drones.
