Skywire® Embedded Modem Roadmap

Skywire® Cellular Modems

Created by award-winning developers, Skywire® plug-in cellular modems are the fastest way to provide cellular connectivity for machine-to-machine (M2M) products and speed them to market. Within months of its introduction Skywire® was recognized for innovation and named a finalist for the ECN Impact Awards, Boards, Modules and Embedded Systems category.

Skywire® is the smallest end-device certified cellular modem on the market, making it quicker and easier to deploy than module down, external modems, or solder-in modules. It uses the Skywire standard form factor and its pre-certification eliminates months of delay and tens of thousands of dollars of cost for required certification.

It is easy to deploy, requiring just voltage and a UART connection and is more flexible than other plug-in modules, supporting a wider range of voltages and antenna connections.
