Dubai International Airport has implemented IoT-based perimeter security systems that enhance surveillance and reduce security breaches. 

3. Improving Passenger Experience

Personalized Services: IoT can personalize the passenger experience by providing tailored services. Smart kiosks and mobile apps can offer real-time information on flight status, gate changes, and baggage claim areas. Passengers can also receive personalized offers and recommendations based on their preferences and travel history. For example, Heathrow Airport's mobile app uses IoT data to provide personalized updates and services to passengers and they are implementing a WhatsApp system to enhance passenger experience. 

Wayfinding: Navigating large airports can be challenging for passengers. IoT-enabled indoor positioning systems (or beaconing solutions) can provide real-time navigation assistance, guiding passengers to their gates, restaurants, restrooms, and other facilities. Munich Airport has implemented an IoT-based wayfinding system that helps passengers navigate the terminal efficiently, reducing stress and improving the overall experience.

Queue Management: Long queues at check-in counters, security checks, and boarding gates can be a significant source of frustration for passengers. IoT can monitor queue lengths in real-time and alert staff to open additional counters or lanes as needed. This dynamic management of queues helps reduce waiting times and enhances passenger satisfaction. At London Stansted Airport, IoT sensors are used to monitor queue lengths and manage passenger flow more effectively.

4. Smart Infrastructure
