With efficient networks, high-speed communications and optimum mobility, building complex THE SQUAIRE at Frankfurt Airport is certainly hitting the headlines. It is one of the largest office buildings in the world in which high-tech plays a central role. Since February 2012, a MiniMetro system by LEITNER has linked the car park with the main building, thus impressively demonstrating that comfortable and reliable passenger transport is possible at low cost and with a high level of environmental sustainability.
