A standard GPRS, 3G, or NextG modem requires the field device to be IP capable and implement VPN encryption. Many existing field devices do not support such modems. A smart modem on the other hand, once loaded with the Telemetry Plus software can transparently manage the IP connection and VPN functions on behalf of the field device, creating a virtual serial connection across the network.
