5G is coming fast. According to CSS Insight data , there will be 340 million 5G connections globally by 2021 and a staggering 2.7 billion by 2025, mostly in developed markets. In money terms, in the aviation industry 5G amounted to just USD 0.2 billion in 2019 but is projected to reach USD 4.2 billion by 2026.

Fast forward: how will we use 5G in 2025?

1. 5G will be the lifeblood of IoT: 5G will soon be commonplace at airports and the idea of everything intelligently connected to everything will be viable. The Internet of Things (IoT) brings the inherent need to manage increasing amounts of objects and therefore data. Today’s 4G technology can manage around 10,000 devices in each square kilometer; a 5G network can manage a million. Multiple objects at airports will interact with people and objects will interact among themselves. With 5G, connectivity will be much more fluid and flexible. The new networks will enable massive data flows, providing secure, real-time, predictive and historic views of airport operations. This will make collaboration between airports, airlines, ground handlers, air traffic managers and concession holders easier and effective. The result will be the intelligent monitoring of queues throughout the airport and tracking and controlling autonomous vehicles that assist passenger journeys. Vehicles on the ramp will be served by connected smart tugs and baggage carts. Wheelchairs, mobile kiosks, and robotic assistants will be controlled remotely. It is not all about bandwidth. 5G’s low latency will make autonomous vehicles much safer. With signals going up to 100 times faster than 4G, the speed of digital instructions will make the difference between a vehicle traveling tens of meters or just a few centimeters before taking corrective action.
2. 5G will power air transport-specific AI applications: 5G connected Artificial Intelligence (AI) will solve major pain points at airports and borders. For example, biometrically matching passengers to their bags will be simple. AI will be able to recognize unique scuff marks, creases, and material characteristics to distinguish between seemingly identical bags and match them to the correct passenger. AI-assisted computer vision will continually scan boarding gate areas and intelligently predict capacity issues for hand luggage on flights and enable staff to act accordingly before boarding.
3. 5G will drive operational efficiency, increase ancillary revenues and cut costs: Putting IoT and 5G together will offer great opportunities for airlines and airports to unlock the value of all their data to deliver tangible business benefits. All airport assets will be connected, making monitoring efficiency and optimizing usage much simpler. It will, for example, provide the tools to make vehicle usage around the airport more efficient, delivering considerable savings in fuel costs and overall resources, including labour.
4. 5G will mean exploitation of the potential of ‘flying data centers’: 5G will enable the next-generation aircraft to exchange vast amounts of data around the airport and at the gate. The fast transmission of aircraft data, and analysis of that data, will enable pro-active maintenance, quicker aircraft turn-around, more on-time departures and, most importantly, an improved customer experience. Convergence of 5G and satellite communications will serve the end-to-end approach of the aircraft as an IoT-flying device, connecting it with all the relevant systems.
5. Airports will control Wi-Fi quality and have improved disruption management capabilities: We see opportunities in licensed and unlicensed 5G spectrums thanks to new 5G standards. Airports will have more control of quality of service in their private and public spaces, converging 5G with Wi-Fi networks to create a seamless mobile experience, with continuous connectivity. 5G is likely to replace the commonly used digital radio communications service TETRA, which is only voice-enabled, for operational and mission-critical services, providing a secure network for running airport operations. Airport staff will have access to real-time rich video updates and live feeds based on evolving scenarios and locations, as well as CCTV feeds for computer vision analysis for many functions and enabled remote biometrics.
6. 5G will deliver the digital traveller promise: For passengers, real-time augmented reality and personalised mobile services will be provided, combining all data exchanged from the various applications and interactions with the building and objects. The airport will provide passengers with relevant, contextualized information and services to assist and entertain them.
