As part of the Nigerian Airspace Management Agency (NAMA)'s effort to modernize and prioritize safety, Spanish information technology and defense systems company, Indra Sistemas, has completed the installation and testing of its voice communications system in 13 Nigerian airports. 
In addition to the introduction of uninterrupted power supplies to navaids at the nation’s airports, NAMA has of late been working to improve Nigeria's ageing aviation infrastructure with air traffic controllers having recently been trained to handle Area radar control at both Lagos and Kano area control centres.
Under the course, controllers will also have experience in using Indra's SDC-2000 Rev. 2.0 voice communications system based on VoIP technology and which complies with the latest European standards (Eurocae).
The system guarantees a reliable and quality link between the controller and pilot, covering wide areas of the country. The operator has a user-friendly access to the radio and telephony services, which are fully monitored and supervised by the management system (TMCS).
