Fremont, CA – The Republic of Macedonia’s Agency for Electronic Communications (AEK) has awarded TCI a multi-million dollar contract to supply, install and commission a technologically innovative National Spectrum Monitoring and Geolocation system for the country.

The TCI contract provides AEK with the world’s first national system for hybrid geolocation of radio transmitters based on integrating angle-of-arrival (AOA) and time-difference-of-arrival (TDOA) techniques for enhanced speed and precision.
