About Wireless WAN SonicWALL appliances such as the TZ 190, TZ 200, and TZ 210 have a WWAN capability that can be used for the following: • WAN Failover to a connection that is not dependent on wire or cable. • Temporary networks where a pre-configured connection might not be available, such as trade-shows and kiosks. • Mobile networks, where the SonicWALL appliance is based in a vehicle. • Primary WAN connection where wire-based connections are not available and cellular is. Wireless WAN support requires a wireless card and a contract with a wireless network provider. See the SonicWALL documentation that comes with the security appliance for more information. GMS provides for complete management of SonicWALL security appliances that are WWAN/3G-capable, and running SonicOS Enhanced 3.6 and above.
