4G LTE can provide either primary connectivity or backup communications, offering network resiliency for business continuity. With greater agility and speed to deployment than wired solutions, 4G LTE can reduce network cost, and it complements wireline public and private network access. Practical applications of 4G LTE for organizations include parallel networks, primary connection, failover, in-vehicle connectivity, network convergence, and last-mile diversity. The 4G LTE NIM with the Cisco 4000 series Integrated Services Router leads the industry in bringing enterprise grade functions such as Quality of Service (QoS), Multi-Virtual Route Forwarding (Multi-VRF) , advanced VPN, and Unified Communications solutions over LTE.
