Cisco - C819G-4G-G-K9-RF - Cisco 819G Cellular, Ethernet Wireless Integrated Services Router - Refurbished - 4G - LTE 800, LTE 900, LTE 1800, LTE 2100, LTE 2600, WCDMA 900, WCDMA 2100 - LTE, UMTS, HSPA+ - 2 x Antenna - 4 x Network Port - 1 x Broadband

The Cisco® 819 Integrated Services Router Family, designed in compact hardened and non-hardened form factors, is the smallest Cisco IOS® Software router with support for integrated fourth-generation (4G LTE) wireless WAN (mobile broadband backhaul) and WLAN capabilities. The Cisco 819 ISR gateway provides a rapidly deployable, highly available, reliable, and secure solution designed specifically for machine-to-machine (M2M) applications. Markets that benefit from these applications include industrial automation, transportation, financial, health care, utility, and retail. Fully integrated with Cisco IOS Software, the Cisco 819 family delivers, enterprise-class features, including highly secure data, voice, and video communications to stationary and mobile network nodes across wired and wireless links. Figure 1 shows a Cisco 819HG Integrated Services Router.

The Cisco 819 ISR is available in both non-hardened (Cisco 819G) and hardened (Cisco 819HG) versions. (Figures 2 and 3, respectively). Both models include support for 4G LTE wireless WAN (WWAN) speeds. Support for 4G offers cost-effective, rapidly deployable, reliable, and secure primary or backup connectivity. With support for industrial-grade components, the hardened Cisco 819HG extends the ISR M2M Gateway footprint and provides deployment flexibility. The Cisco 819HG is an ideal solution for stationary and mobile environments where space, heat dissipation, exposure to extreme temperatures, harsher environments, and low power consumption are critical factors.

For mobile applications, Cisco Mobile IP delivers transparent roaming across multiple wireless networks capable of covering wide geographic areas.

A critical component of the Cisco M2M architecture, the Cisco 819 ISR serves as the single, horizontal platform which enhances the Cisco implementation of "any device, anywhere, any place" across multiple industries, including banking, retail, healthcare, manufacturing, 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.
