Technology at Johannesburg Airport in South Africa (OR Tambo) was upgraded last month to improve aircraft-to-ground crew communications.
The project was by carried out by airport and airline technology firm SITA and completed in time for the large increase in air traffic expected for South Africa's main airport during the FIFA World Cup.
The upgrade centred on installing a VHF Digital Link station at Tambo to replace the existing VHF ACARS system - these provide the communication systems between pilots, ground crew and air traffic controllers.
VDL is a newer system backed by the International Civil Aviation Organisation to dramatically increase capacity over old systems. In this case SITA says the new system will improve the bandwidth ten-fold.
One of the main reasons, of course, to massively improve the comms at Tambo is so that the giant Airbus A380 aircraft can operate in and out of the airport and surrounding airspace alongside other traffic.
The A380's are "bandwidth-hungry", says SITA, meaning the upgrade was needed in time for the World Cup as many of the airlines operating the aircraft plan to use them during the tournament on flights to South Africa.
Not least Lufthansa, which brought the German World Cup squad to Johannesburg earlier this week.
Air France is also operating A380s to SA during the World Cup.
