Product Details

The First of Its Kind

OptConnect ema™ is the world’s first smart embedded modem solution for M2M/IoT applications. ema eliminates the delays, complexities, and frustrations of typical cellular deployments providing a complete connectivity solution.

OptConnect ema™ includes onboard intelligence that provides all the monitoring, manageability, security, reporting, certifications and autonomous self-healing of the connection. That’s what makes ema different. We’ve built ema to be truly intelligent, truly managed, and truly monitored. With plug and play functionality built right in, all the customer host board has to do is just use it.

Easy to Implement

OptConnect’s fully managed smart embedded modem allows companies to focus on their core business strengths and outsource one of the biggest stumbling blocks for IoT projects in order to get to market faster, reduce costs, and increase the success rate of their projects. With our ema:Play evaluation platform, customers have a development platform, or sandbox environment, to bring their IoT ideas to life. We also have a mPCIe adaptor so customers can integrate into existing boards that have an open mPCIe slot.

All-Inclusive Rate Plan

OptConnect provides a simple, fully managed solution for your device connectivity needs. Rather than just selling a piece of hardware and leaving the management to the customer, we include a full suite of managed services so you can focus on your core business. Our Connectivity-as-a-Service model means you get everything you need to simply plug in your device and know you have the #1 trusted partner in managed wireless IoT connectivity handling everything else.

We include the hardware, the data plan, carrier management, and monitoring, secure private network, 24/7/365 Customer Care Center based in the USA, robust customer dashboard for device-level management, robust warranty coverage, alerting and monitoring, and so much more.
