General Description
The Cisco 819 ISR is a standard form factor with a commercial operating range. The 3G Cisco 819 ISRs
support the 3G speeds (High-Speed PacketAccess Plus [HSPA+] enabling up to 4G speeds and Evolution
Data Optimized [EVDO Rev A]). They are backward-compatible with High-Speed Packet Access
(HSPA), Universal Mobile Telecommunications Service (UMTS), Enhanced Data Rates for Global
Evolution (EDGE), General Packet Radio Service (GPRS), and EVDO Rev 0/1xRTT.
The 4G LTE C819 supports the latest Third-Generation Partnership Project (3GPP) Release 8 LTE
standards. The Cisco 4G multimode LTE WWAN C819 provides persistent and reliable LTE connectivity
with fallback and transparent handoff to earlier technologies. The Cisco 819HG-4G and Cisco 819G-4G
support multimode 4G LTE and have embedded Sierra Wireless multimode modem.
The Cisco 819 ISR is a desktop form factor with built-in wall-mount features, floor mount, and DIN rail
mount features in selected SKUs. These routers are powered by an external AC power or optional DC
adapter.
Beginning with IOS release 15.2(4)M1, the new 3G Cisco 819HGW and Cisco 819HWD ISRs support
WiFi radios with a higher memory density and a new barrel-type power connector. A Wireless Local
Area Network (WLAN) implements a flexible data communication system frequently augmenting rather
than replacing a wired LAN within a building or campus. WLANs use radio frequency to transmit and
receive data over the air, minimizing the need for wired connections.
