Overcoming the barriers of language and conveying all the necessary information accurately

Airport passenger announcement broadcast system

The international airport terminal is the gateway to the sky. Precisely because it is a place where many people of diverse nationalities come and go, an infrastructure for conveying information accurately and reliably is critical. Our “airport passenger announcement broadcast system” with its multilingual capabilities allows for announcements about flight information, emergencies and the like to be made in a variety of languages, which makes for a more comfortable travel experience and smoother airport management.
