Optus and Ericsson have jointly deployed an indoor 5G solution at the operator's Coffs Harbour retail store.

The installation extends 5G coverage into the store interior rather than relying solely on outdoor macro signals reaching the building from nearby towers. Indoor 5G typically relies on distributed antenna systems or small cells mounted inside the retail footprint.

Coffs Harbour serves as a regional centre on the New South Wales Mid North Coast. The store functions as both a sales outlet and a live demonstration venue for prospective subscribers evaluating handset performance on the sales floor.

Ericsson supplied the radio infrastructure for the site. The Swedish vendor holds the principal radio access network contract with Optus under a long-standing managed services and infrastructure partnership.

For practitioners, the move addresses a structural weakness in outdoor macro deployments. Modern building materials including Low-E glass and foil-backed insulation attenuate mid-band 5G signals, reducing usable throughput inside contemporary fit-outs. A ceiling-mounted small cell bypasses that attenuation by placing the radio within metres of the user's device.

The retail demonstration angle carries commercial weight beyond raw technical performance. Australian mobile retailers compete on in-store experience as well as plan pricing. A working 5G signal inside a regional shop lets sales staff demonstrate high-bandwidth applications on the sales floor itself, turning the retail outlet into a live technical reference site. Optus has been repositioning selected regional stores as experience-led venues.

Optus competes with Telstra and TPG Telecom across both metropolitan and regional Australia. Telstra remains the largest mobile operator by subscriber count. TPG Telecom operates the Vodafone brand in the mobile segment. The Coffs Harbour deployment extends Optus's regional retail strategy into the live 5G demonstration tier that Telstra has used in its larger metropolitan flagships.

What does this mean for the vendor picture?

Ericsson and Nokia compete for indoor 5G reference deployments across Australian retail, transport and stadium venues. Each contract strengthens the winning vendor's position for follow-on enterprise work in shopping centres, airports and hospital campuses. Nokia remains Ericsson's principal competitor for Tier-1 mobile operator contracts in Australia and globally.

How does this fit Optus's broader 5G rollout?

The operator has been expanding 5G coverage across regional New South Wales and other state markets. Coffs Harbour sits within Optus's stated regional coverage footprint, where mid-band capacity now supplements earlier low-band deployments designed for wide-area reach. The mid-band layer handles capacity-dense traffic. Low-band carries the coverage obligation into less populated terrain.

What changes for retail staff and customers on the floor?

Sales representatives can demonstrate download speeds, 4K streaming and cloud gaming on the sales floor itself. Customers gain direct visibility into the technology before committing to a device upgrade or a higher-tier plan. The format also gives engineers a controlled environment for tuning indoor radio parameters such as transmit power, antenna tilt and frequency assignment.

Why does the regional retail site matter strategically?

Mobile operators have been increasing capex on regional retail infrastructure as a defence against fixed-line broadband competitors and over-the-top service providers. Tier-two and tier-three Australian cities, including coastal tourism centres such as Coffs Harbour, generate concentrated seasonal data traffic that benefits from dedicated indoor capacity. Hotels, cafes and conference venues inside the same catchment gain a measurable signal-quality uplift.

Looking forward, the Coffs Harbour deployment positions Optus and Ericsson to replicate the indoor 5G template at additional regional sites as mid-band coverage continues to expand across the operator's footprint.
