Introduction to Cisco URWB IEC-6400 Edge Compute Appliance

The IEC-6400 Edge Compute Appliance uses the Cisco Ultra-Reliable Wireless Backhaul (URWB) technology with Cisco’s UCS C220 M6 Rack Server. Cisco URWB is a wireless technology that enables you to connect moving assets or extend your network where running fiber is not feasible or affordable. The IEC-6400 Edge Compute Appliance acts as gateway in a URWB network. One of the most important functionalities of the IEC-6400 gateway is to handle aggregate throughput up to 40 Gbps.

Cisco URWB network can be designed for Layer 2 use cases (such as when connecting automated guided vehicles (AGVs) or autonomous mobile robots (AMRs) on a factory floor) as well as Layer 3 use cases (such as for train-to-trackside communications in subways or railways), allowing the network to scale in size without compromising reliability and availability. The IEC-6400 gateway is a perfect fit in both Layer 2 and Layer 3 architectures, whenever a dedicated gateway is required to support advanced mesh end capabilities.
