Skywire® 4G LTE CAT 1 Embedded Modem for AT&T – Sierra Wireless


This Skywire® 4G LTE CAT 1 embedded modem is based on the Sierra Wireless LTE CAT 1 module. This LTE CAT 1 embedded modem is end-device certified with PTCRB, FCC, IC and AT&T which enables fast and cost-effective development. And, like all Skywire’s, this modem is deigned to be easy to integrate, which reduces project risk and accelerates time to market. All Skywire embedded modems are available with data plans from Major North American carriers as well.

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-S7648 Skywire® modem is end of life. It is not recommended for new design (NRND).
