For communication between air navigation controllers and pilots, Skyguide operates a radio system consisting of
700 radio communication devices and 46 transmitting and receiving stations. The Smart Radio project launched
in 2012 to renew the entire main radio system will be completed in 2021. The latest generation of radio equipment
is significantly improving energy efficiency. It consumes 30% less energy compared to the previous equipment,
thus saving up to 200 MWh of power per year. The technical team now maintains the system remotely, saving
13,000 kilometres of maintenance journeys.
