Private 5G rollout at Port Nelson to fix Wi-Fi dead zones

The deployment spans around 30,000 square metres across three warehouses.

Port Nelson has deployed a private 5G network with Spark New Zealand and Ericsson across its warehouse operations to support real-time logistics, inventory tracking, and safety communications.

Ericsson said in a press release that the deployment spans around 30,000 square metres across three warehouses in Nelson and Blenheim.

It added that the system addresses connectivity gaps caused by high-density block-stacking storage and complex site layouts that previously created Wi-Fi dead zones and disrupted forklift scanning processes.

Warehouse operations at Port Nelson handle exports and imports, including forestry products, pipfruit, wine, and seafood, where forklift operators scan each pallet as it moves through storage and distribution workflows.

The private 5G system uses Ericsson Private 5G with a dedicated core and small cell radios across warehouse and yard areas to provide continuous coverage for real-time data exchange.

Port Nelson has also deployed Ericsson Cradlepoint R1900 routers on forklifts, which support dual-SIM connectivity and enable switching between private and public 5G networks when vehicles move outside private coverage areas.

Ericsson said the network improves operational visibility through its NetCloud platform, allowing monitoring of connectivity performance and issue detection.

The system also supports digital push-to-talk communications and location-based alerts designed to improve safety in areas with moving vehicles and cargo handling activity.

Ericsson said future applications could include real-time asset tracking, predictive maintenance, enhanced CCTV systems, artificial intelligence-enabled vision, and automation across port operations.
