Chapter 1 Product Overview
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. Figure 1-1shows the Cisco 819HG ISR.
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. Figure 1-2shows the Cisco 819HGW ISR.
The WLAN for 3G Cisco 819HGW and Cisco 819HWD ISRs have the following additional features:
•Dual 802.11 a/b/g/n radios
•External WiFi antenna
•WLAN LED
Note Cisco 819 is used to refer to Cisco 819HG, Cisco 819G, Cisco 819H, Cisco 819HGW, Cisco 819HWD, Cisco 819HG-4G, and Cisco 819G-4G ISRs unless specifically called out otherwise.
