Case Study: u-blox Enables Global Remote IoT Connectivity with Hologram Satellite Fallback

u-blox reaches 10% of Earth’s surface with Hologram satellite IoT connectivity

u-blox faced the challenge of keeping IoT devices connected in remote locations far beyond the reach of cellular networks, which cover only a small percentage of the Earth's surface. Hologram provided satellite IoT connectivity to solve this last-mile problem for remote deployments.

The solution implemented by Hologram was a resilient design pairing multi-carrier cellular with satellite fallback, using a hybrid single-SIM setup. This approach allowed devices to use cellular as the primary link and automatically switch to satellite backup only when necessary, optimizing for cost and power efficiency. This ensured that critical assets like those in maritime, agriculture, and logistics remained online, protecting valuable data and preventing costly downtime.
