Challenge Networks

Challenge Networks is a leading provider of private mobile and networks. We design, deploy, and operate private 4G and 5G networks for customers that require secure, reliable, high-capacity wireless coverage to support operational technology use cases on their sites. Our custom-built mobile networks can be deployed on sites such as mines, hospitals, universities, floating platforms at sea, vessels, ports, manufacturing and logistics sites, or any other special-purpose site that requires highly reliable and secure wireless connectivity. In February 2023, Vocus, Australia's leading specialist fibre and network solutions provider, signed a contract to acquire Challenge Networks. The acquisition builds on Vocus' strategy to provide secure, high-capacity connectivity to Australian enterprise and government customers – wherever they are – through its national fibre, satellite, and now wireless network infrastructure.
