Wireless WAN connections that utilize data connections over 3G Cellular networks. The
Wireless WAN (WWAN) can be used for:
• WAN Failover to a connection that is not dependent on wire or cable.
• Temporary networks where a pre-configured connection may not be available, such as
trade-shows and kiosks.
• Mobile networks, were the SonicWALL TZ 190 is based in a vehicle.
