Who we work with

Transport authorities

Offer a better passenger experience and optimise operations with robust wireless connectivity across your entire transport system.

Each day, millions of public transport passengers depend on fast, reliable and secure connectivity to keep in touch with friends and family, stay entertained or get some work done during their travels. But in a country as vast as Australia, it’s a challenge to provide that connectivity at every leg of the journey.

Our shared communications infrastructure can deliver the connectivity passengers expect, no matter where they travel. With experience supporting transport authorities around the world, we can provide the strong connectivity foundation you need to both enhance the passenger experience and optimise your operations.
