A Vanguard 3G unit can operate in an access point mode (Ad-Hoc) and in a client mode.
In access point mode, the Vanguard 3G radio modem offers wireless tether. It forwards local
WiFi traffic to application servers over the cellular network and works in parallel with Ethernet
connection, providing for simultaneous WiFi and Ethernet connections (see Figure 17A).
In client mode the Vanguard 3G unit can automatically switch between cellular and WiFi
connections providing for seamless handover when coupled with modern applications (see
Figure 17B).
