The airport, owned and operated by BAA, opened in 1946, and through the 20th century developed facilities designed to handle 45 million people annually. Their challenges are they need to secure separation of public and internal service traffic, on the same network, meet the needs of resilience, scalability and flexibility of a large infrastructure deployment and a vendor that would be flexible and prepared to work closely with BAA and its contractors. They chose Aruba Networks to overcome these challenges. They have implemented 6x Aruba 6000 mobility controllers equipped with M3 modules PEF and WIDS license and 800 x AP70 access points. The results of implementing the Aruba Networks were single WLAN infrastructure for all wireless data traffic, secure separation of hotspot traffic from BAA traffic.
