The Cisco 819 ISR is available in both non-hardened (Cisco 819G) and hardened (Cisco 819HG) versions. 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.
