Skywire® 4G LTE CAT 3 Embedded Modem


The Skywire® 4G LTE CAT 3 embedded modem leverages high-speed Category 3 technology and supports LTE (Long Term Evolution), HSPA+, and UMTS communication, minimizing costs of hardware and network access. This modem delivers 100Mbps download speeds and 50Mbps upload speeds over mobile networks, and features a U.FL port for antenna flexibility.

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-TSVG(-B), NL-SW-LTE-TNAG(-B) and NL-SW-LTE-TEUG Skywire® modem is end of life. It is not recommended for new design (NRND).
