3Gpp Gateway is a router that supports multiple types of internet connections.
This article explains how to install a Cisco certified internetworking for the gateway and router in a Raspberry Pi 3.
The gateway uses Cisco Internetworks R3GPP (RC3Gpp) to communicate with the RPC.
The router uses Cisco IPsec (RCIP) to secure the connection.
