GRU Airport - One of the main hubs in Latin America, the International Airport of São Paulo, in Guarulhos, was inaugurated on 20 January 1985 and was privatised through a concession programme on 6 February 2012. From 1985 to 2012, the airport operator Infraero had several radio communication systems inside the airport including MPT1327, conventional analogue, TETRA from other vendors, IDEN and DMR. This happened as Infraero allowed airline, maintenance and handling companies to use their own systems causing the following problems: high interference, lack of general communication in emergencies, high maintenance costs of systems and different contracts, poor service from GRU Airport and lack of radio communication coverage underground and inside buildings and elevators.
The ability to co‐ordinate resources and disseminate accurate information across airport operators is crucial in order to secure passenger safety, improve efficiency and respond efficiently in emergencies. To achieve this, GRU Airport migrated from a multi‐technology, multi‐system environment into one secure, reliable TETRA voice and data system securing full coverage, allowing communication across all airport operators. The open API enabled easy integration of third‐party applications, and features like DGNA facilitated easy creation of dynamic work groups used for apron services such as luggage handling, fuelling and catering. The case study demonstrates that TETRA is a reliable solution, which meets airport operator requirements.
