Cambium Networks Carrier Class Licensed microwave network supports PNG Air Traffic into the future



The continuous increase in air travel has created a challenge for the air traffic authorities to maintain and upgrade their communications infrastructure to ensure the highest level of air and ground safety. Air Traffic Control requires a mix of communication services to enable effective management of ground and aerial control, as well as ensuring always-on connectivity between the airport, control centres and aircraft. After decades of operation, PNG Air Services decided it was time to upgrade their legacy Radar System to MLAT (Rannoch Multilateration Aeronautical Information Services).

MLAT requires the need to deliver voice, data, radar, guidance systems, video, telemetry and other traffic using a wide variety of interfaces, network structures and technology generations. Above all, given the critical nature of ATC systems their communications must be reliable and secure at all times. Coupled with the complex communications requirement, PNG has some of the most challenging terrain on the planet.

Air Services PNG required a high-throughput, low latency, highly available and redundant licensed microwave networks to link 8 MLAT sites around the complex, rural and challenging terrain of PNG. This was to enable them to bring their air traffic management systems up to date so that they could include such services as airport surface surveillance, approach surveillance for ground and aerodrome control, surveillance in airspace with and without radar coverage as well as providing data for ground based operations such as noise monitoring and gate provision and management.

A very scalable, future-proof solution was installed using Cambium Network’s PTP820G fully redundant licensed microwave ring using G.8032 Ethernet Ring Protection (ERP) with greater than 99.9% availability, redundant power and less than 8ms of latency. TE (PNG) Ltd was chosen to design, integrate, and commission the solution to ensure the critical communication needs of Air Services PNG were met. To help support the implementation of this complex solution, BMS Network Solutions was also on hand to provide training support to both teams on the ground in PNG.

PNG can now confidently deploy the world-class Air Traffic Control system which is reliable, future-proof and state-of-the-art.  Airport operations can now be performed more efficiently and ever more safely. The reliable communications network across very difficult terrain now provides secure communications enabling the Air Services PNG to perform ever more complex air traffic management operations. Air Services PNG are now looking to grow the Cambium Networks PTP820 footprint further across the PNG.
