Skywire® 4G LTE CAT 1 North America Embedded Modem


NimbeLink, a global leader in embedded cellular modem technology and asset tracking solutions, has introduced the Skywire® 4G LTE CAT 1 NA modem. This Skywire modem leverages Category 1 technology.  The NL-SW-LTE-TC1NAG is ideal for delivering fast reliable cellular connectivity to products with applications in North America. The modem supports GNSS, dual SIMs, a single SKU for both AT&T / Verizon networks, integrated TCP/IP stacks, plus is AT&T’s FirstNet (Band 14) capable.

The NL-SW-LTE-TC1NAG is pin compatible with NimbeLink CAT 3 modems, NL-SW-LTE-TNAG-X & NL-SW-LTE-TSVG-X, and the CAT 4 NL-SW-LTE-TC4NAG. This modem is ideal for applications requiring lower throughput than CAT 3 and CAT 4 modems, with the added benefit of a lower cost product and dual-carrier firmware (also supported by NL-SW-LTE-TC4NAG).

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.
