WAN Backhaul Configuration
A
Wireless Wide Area Network
(WWAN) card is a specialized network interface card that allows a network device to
connect, transmit and receive data over a Cellular Wide Area Network. 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.
