In fast-growing countries, the role of airports is constantly increasing. For example, Pudong Airport in Shanghai, China, and Inchon Airport, Seoul, Korea, recently required reliable, low-maintenance systems displaying flight information. To control the huge and ever-growing passenger traffic, both airports needed a flow control system and passenger assistance by sending messages from an ever-changing base to many LCD monitors located in strategic locations of airport premises. These systems transmitted information on arrival / departure flights, check-in, point of baggage collection and even weather forecast at the destination.
Given that Pudong serves more than 29 million passengers a year, and Inchon more than 31 million, it was critically important to introduce the most modern technologies and solutions. Any potential technical error could create huge problems that would affect the work of many airports.
