A number of reports describing airport TETRA systems can be downloaded from the Case Studies page of the TETRA Association’s website, www.tetramou.com Web linkswww.air-radio.com, www.analysysmason.com, www.artevea.com, www.euro-cdm.org, sepura.com">www.sepura.com, sita.aero">www.sita.aero, www.telvent.com, www.tetratab.com, www.zonith.com Optimizing movements of staff and ground resourcesMore than 90 international airlines operate from Madrid-Barajas Airport, the largest in Spain and a major European hub. In 2009, the airport processed more than 48 million passengers. Helping to manage its vehicle operations on the ground is a fleet management system developed by Telvent, which employs the airport’s TETRA network for secure exchange of data. Vehicles are equipped with an on-board unit and touch-screen PC connected to a TETRA terminal, which gives the vehicle operator GPS location/navigation capabilities and access to corporate applications. Seven modules make up the TelMMA platform:
Using this system, Telvent explains, operators can optimize the management of many airport processes, improving the quality of services they provide to airport customers. The system also reduces operational costs – particularly fuel costs – and supports the co-ordination of emergency operations staff. Because of the interoperability of TETRA systems, it can be implemented at any airport equipped with a TETRA network, regardless of the infrastructure brand or manufacturer. The solution is adaptable and modular, allowing integration with other applications. Reliability, security, functionalityAs part of a modernization programme at Cochin International Airport, in the State of Kerala, India, a new TETRA network is being installed. It will replace an analogue radio installation. The Indian branch of Siemens Information Systems has been the turnkey contractor and integrator for the supply, installation and commissioning of the network. All TETRA components are being supplied by VSpectra Communication, of New Delhi. They include infrastructure from Rohde & Schwarz and radio terminals from Sepura. Operating frequencies for the system are in the 380–430?MHz band. “Airports are fast moving, very busy environments that provide one of the toughest tests for communications systems”, commented Subir Kochhar, of VSpectra. “TETRA has proven to be an excellent solution, delivering the reliability, security and functionality required in airports. “In addition, thanks to its four time-slots in the 25 kHz channel spacing, TETRA provides larger network capacity than analogue technology.” One particular advantage of the TETRA technology is its clearer audio, which is expected to be especially helpful during the heavy rains of the monsoon season. Kochhar continued: “The lightweight and compact Sepura terminals offer better voice quality than the old analogue terminals that they’ve replaced – so it was easy to convince Cochin’s airport authorities to adopt Sepura TETRA radios”. Also used at Cochin will be Sepura’s powerful SRG gateways. Checking in at DüsseldorfAfter Frankfurt and Munich, Düsseldorf has the third largest airport in Germany. In 2009, Düsseldorf International Airport transported 17·8 million passengers and managed an average of 600 aircraft movements a day. Located about nine kilometres from the city, the airport hosts 70 airlines and offers flights to 180 non-stop destinations on all continents. It is the main hub for Air Berlin and has also become a new hub for Lufthansa, which operates about 300 flights a day to and from Düsseldorf. In addition, Lufthansa has selected Düsseldorf as the diversion airport for its giant Airbus A380 aircraft in case of bad weather at Frankfurt.
