A critical component of the Cisco M2M architecture, the Cisco 819 4G LTE ISRs serve as the single, horizontal platform that enhances the Cisco implementation of "any device, anywhere" across multiple industries, including small business, small remote branch, banking, retail, healthcare, and government. It also provides the ability to extend Cisco product-based networks to small branch offices with a relatively low incremental investment, as well as to enable managed services offerings based on Cisco architecture.
Cisco Mobile IP delivers transparent roaming across multiple wireless networks capable of covering wide geographic areas. Additionally, the Cisco 819 ISR supports enterprise class built-in Wireless LAN (WLAN) capability. The Cisco 819GW platforms concurrently support both 4G LTE for wireless WAN backhaul and Cisco dual radio WLAN on the same platform. The 802.11a/b/g/n 2X3 MIMO built-in Cisco 3500 Access Point (AP) in the Cisco 819, comes with Cisco's CleanAir technology, to create a self-healing, self-optimizing WLAN. Moreover, with the advantage of dual radio, the integrated AP can serve both as an access point and as a client to a wireless mesh network. This provides another source for WAN diversity along with Gigabit Ethernet, serial, and cellular. The AP ClientLink feature improves reliability and coverage for legacy devices and dynamic frequency selection (DFS allows detecting and avoiding interference with radar signals to comply with regulatory domains.
