CHAPTER 1
Overview of the Intelligent Wireless Access
Gateway
Service providers use a combination of WiFi and mobility offerings to offload their mobility networks in
the area of high-concentration service usage. This led to the evolution of the Intelligent Wireless Access
Gateway (iWAG).
The iWAG provides a WiFi offload option to 4G and 3G service providers by enabling a single-box solution
that provides the combined functionality of Proxy Mobile IPv6 (PMIPv6) and GPRS Tunneling Protocol
(GTP) on the Cisco Intelligent Services Gateway (Cisco ISG) framework. This document provides information
about the iWAG and how to configure it, and contains the following sections:
