A statement from the company said Dense Air had won spectrum in the six largest Australian cities. The acquired spectrum supports 5G operation in 3GPP band n77/78.

Dense Air is a wholesale network operator that “enhances and extends” coverage and capacity by offering neutral host “Carrier of Carriers” services, supporting multiple operators on the same physical 5G small cell or 5G femtocell.

It aims to extend 5G coverage and capacity to outdoor and indoor locations that are the hardest to reach.

The company has a fully managed service for both mobile and fixed network operators, made possible by targeted mass deployment of small cells.

It will be able to start operating in Australia when licences are issued and handsets for the 5G eco-system, are available.

Dense Air chief executive Paul Senior said: “We are absolutely thrilled to have acquired 5G spectrum in the major metro areas of Australia. Our spectrum enables us to offer a completely new type of wholesale service to 5G network operators.

"Dense Air will complement planned 5G deployments, by allowing much greater densification than can be achieved with macro cells alone. By offering both 5G enterprise small cells and 5G residential femtocells, we can in-fill missing coverage and enhance capacity.

"Our mission is to help improve an operator’s 5G business cases, which still remains very challenging for both MNOs and MVNOs alike."
