Skywire® 4G LTE CAT 4 EU Embedded Modem


The Skywire NL-SW-LTE-TC4EU embedded modem is the fastest and most cost-effective way to bring cellular connectivity to your IoT products in Europe. Approved for use on the Orange LTE CAT 4 network with fallback to 2G/3G, the CAT 4 EU modem delivers exceptional download and upload speeds.

Skywire embedded modems dramatically reduce the cost, risks and timelines of IoT product development. With known-good RF engineering and fully validated software, Skywire allows you to focus on your application and not engineering cellular radios. Standardized connectivity gives you flexibility to update and alternate radios for new geographies, carriers and technologies. Further, our embedded modems are “End-Device Certified”, meaning your end-product will not need to go through the complex process of carrier certification. This is critical for the first release of your product and each iteration as you obtain market feedback. Skywire modems significantly reduce time-to-market and are ideal for product development through large-scale production. All Skywire modems are patented and backed by industry leading documentation and expert-level product support.

The NL-SW-LTE-TC4EU Skywire® modem is end of life (EOL). It is not recommended for new design (NRND).
