SITA Looks at How 5G Will Help to Transform Airports

SITA, a leading IT provider for the air transport industry, has made six predictions about how ultra-fast 5G networks will bring major change to airports, airlines, and passengers.

With download speeds for mid-band 5G of up to 400 Mbps, and perhaps even well beyond that in the future, there is no doubt that 5G will be a game-changer. The potential for innovation is huge and airports, airlines, and passengers will feel the force of 5G in very different ways.

SITA’s predictions are based on unique IT insights and emerging air transport industry technology trends. They follow hot on the heels of 5G trials like the recent ones carried out by both London Gatwick Airport and Beijing’s new Daxing International Airport services which signpost our entry into a new era of ultra-connected air travel.

Gilles Bloch-Morhange, VP SITA Platform, said, “5G is already enhancing our existing applications at airports, for aircraft communications, airport operations, baggage management, and of course passenger processing. And it’s impossible to talk about 5G without discussing Internet of Things, Artificial Intelligence and the other applications it enables. We’re already using 4G for IoT applications for several applications around our biometric passenger processing solution, such as Smart Path and baggage management and the uptake of 5G will provide many more opportunities.”

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?

- 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.

- 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.

- 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 labor.

- 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.

- 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.

- 5G will deliver the digital traveler promise

For passengers, real-time augmented reality and personalized 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.

HD films will download in seconds, entire series will be available to watch offline almost instantly and passengers will be able to live stream sports events in crystal clear quality, no matter how busy the airport.
