4G LTE is being used to provide both primary connectivity and network resiliency for business continuity. With greater agility and speed-to-deployment than wired solutions, 4G LTE reduces network cost and complexity while maintaining ROI. Practical applications of 4G LTE for distributed enterprises such as parallel networks, primary connection, failover, in-vehicle, network convergence, and wireless WAN diversity. The 4G LTE EHWICs with ISR G2 is the industry leader to bring enterprise grade wireline like functionality such as Quality of Service (QoS) for cellular, Multi-VRF for cellular and Unified Communications solutions over LTE.
