The essential wireless foundation for the digital airport. The adoption of Industry 4.0 digital technologies, such as IoT, AI, machine learning and data analytics are expected to revolutionize the operations of airports, introducing greater automation, improved processes, better tracking and handling of everything from aircraft to baggage — all with the goal of improving the passenger experience. Essential to this digital transformation will be high performing, secure and very reliable wireless communications. Neither the Wi-Fi networks currently in operation in most airports nor the public mobile networks that serve them have what is required to support the most ambitious digital transformation of the airport.
