Digi's WR54 Dual-SIM cellular rugged routers for transportation applications employ Gobi LTE Advance technology allowing use on major networks. Dedicated PCIe® 2.0 internal data buses deliver 10 GT/s aggregate bandwidth ensuring low latency, high bandwidth cellular communications. Four gigabit Ethernet ports connect other IP capable systems, each configurable as an isolated, secure LAN, or all four can function as a layer 2 switch. Digi TrustFence®, a suite of hardware and firmware features, ensures the integrity of Digi WR54 security functions. A cryptographic co-processor protects sensitive data such as stored passwords and encryption keys.
