A Wireless Wide Area Network (WWAN) card is a specialized network interface card that allows a device to connect, transmit and receive data over a Cellular Wide Area Network. The RFS4000 and RFS6000 each have a PCI Express card slot that supports 3G WWAN cards. The WWAN card uses point to point protocol (PPP) to connect to the Internet Service Provider (ISP) and gain access to the Internet. PPP is the protocol used for establishing Internet links over dial-up modems, DSL connections, and many other types of point-to-point communications. PPP packages your system‘s TCP/IP packets and forwards them to the serial device where they can be put on the network. PPP is a full-duplex protocol that can be used on various physical media, including twisted pair or fiber optic lines or satellite transmission. It uses a variation of High Speed Data Link Control (HDLC) for packet encapsulation.

To switch to the WWAN Interface configuration mode, use the following command:


<DEVICE>(config-profile-<DEVICE-PROFILE-NAME>)#interface wwan1

Interface configuration commands:
  apn          Enter the access point name provided by the service provider
  auth-type    Type of authentication, Eg chap, pap
