Helix routers provide a configurable WAN/LAN Ethernet port option and a built-in connection failover feature to ensure business continuity. Sensing when the primary connection fails, the Helix router automatically switches to the 3G wireless network. The router then continuously monitors wireline network availability and automatically reverts back to the primary connection when service is restored. The routers can also provide mobile hotspot access for public transportation vehicles, enabling riders to stay connected on their commutes. It offers a fully IPSec compliant VPN for data security, dual diversity 3G antenna ports, and an optional 802.11b/g WiFi access point with WPA and WPA2 encryption to provide secure access for authorized multiple mobile computing platforms, both on-board and within range of the vehicle.
