Building Secure, Plug-and-Play Connectivity for Critical Infrastructure
FreeWave’s Elements™ ES1000 gateways operate in remote oil fields, utility infrastructure, and other critical environments, where a lost connection puts both operations and security at risk. This case study documents how FreeWave, Velocity IoT, and Flolive rebuilt the connectivity layer underneath the Elements™ ES1000 cellular gateway, so every gateway ships ready to connect, runs across carriers, and no longer relies on public static IPs.
For nearly 40 years, FreeWave has connected remote field assets to the control room. As its cellular deployments scaled, FreeWave set out to make connectivity simpler and more secure for its customers, with no public static IPs, no port forwarding, and no dependence on a single carrier.
Today, every ES1000 ships pre-configured with zero network setup in the field. Three layers of protection and three layers of resiliency keep assets secure and online, without static IPs, port forwarding, or carrier lock-in.
The full case study covers the challenges FreeWave faced at scale, the three requirements FreeWave set for its connectivity, and how the solution was planned and validated before reaching the field.
Inside the Case Study
- Why public static IPs create risk for field assets, and what replaces them
- Why zero-trust access by device, user, and port beats an all-or-nothing VPN
- How multi-carrier access keeps field assets online through a carrier change
- How local packet gateways reduce latency and extend battery life
- How one SIM supports growth from ten devices to ten thousand across continents
