The following are some sample deployments using a PDIF/FA.
Mobile Station using Mobile IP with PDIF/FA
Overview
As shown in the figure below, the PDIF/FA supports the Fixed Mobile Convergence (FMC) application, which employs
a Dual Mode Handset (DMH) to provide a VoIP solution over an IP-based WiFi broadband network. The DMH can
access the traditional CDMA voice and data networks over the Radio Access Network (RAN). Over the RAN, the DMH
implements circuit-switched voice and standard mobile IP (MIP) data over EVDO Rev. A, using the services of a PDSN
and an HA.

Alternately, the DMH can send both voice and data over WiFi when a local AP is available. When the DMH connects to
the AP, it establishes an IPSec tunnel over the broadband access network. This tunnel terminates at the PDIF/FA.
