The Cisco 880G and 890G Series 4G LTE 2.0 ISRs are fixed-configuration routers that provide collaborative business solutions for secure voice and data communications to enterprise small branch offices, with support for the latest Third-Generation Partnership Project (3GPP) Release 9 standards for 4G LTE. They provide persistent, reliable LTE connectivity with fallback and transparent handoff to earlier technologies. The routers are designed to deliver secure broadband, Metro Ethernet or any xDSL variants, wireless WAN (WWAN) connectivity, and business continuity. They also come with powerful management tools, such as the web-based Cisco Configuration Professional configuration management tool, which simplifies setup and deployment.
