Features surveillance functions including multi-lateration (TDOA and TSOA).Supports frequency planning and interference analysis.Dedicated aeronautical propagation models.Automated coverage planning function to reduce network design and deployment processing times.A full geographic dataset to model networks and interference within the airport environment.It features dedicated functions, including: HTZ is technology neutral allowing it to model almost every wireless technology. Airports use an abundance of wireless technologies to connect passengers, devices, safety-critical systems, and aircraft. ATDI specialise in three types of communication systems: ground communications for controlling operations, ground-to-air communications for managing airspace and radars for monitoring en-route operations.
