3G Gateway

The FlatMesh 3G Gateway is a fully integrated unit which provides all the functionality required to operate a FlatMesh wireless sensor network in a remote location.

No fixed IP address is required for the cellular service; the Gateway simply initiates the connection with the FlatMesh Web Monitor software over the Internet.
