IoT Corner

Hyderabad Airport in central India has added IoT capability to all 3,000 of its baggage trolleys, the core of what is called “Smart Baggage Trolley Management.”

The system can locate trolleys in the terminal and help airport staff move them to areas where they are needed to reduce wait times for passengers. The trolleys also have an alarm that sounds if they are moved away from the designated use zones to protect against misuse and theft, and can predict the need for trolleys in certain zones based on arrival schedules. The system is the first of its kind in the country. —Jeremy Losaw
