Cisco dual radio WLAN on the same platform as shown in Figure 2. 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. Figure 2 shows the 819 ISR with integrated 3G and 802.11 a/b/g/n AP. More information on
the Cisco 3500 Access Point is available at

Figure 2. Non-hardened Cisco 819GW Integrated Services Router with 3G and Wi-Fi
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..
Product Overview
The Cisco 819 ISRs for M2M applications supports 3G High-Speed Packet Access Plus [HSPA+] and Evolution
Data Optimized [EV-DO Rev A]), enabling up to 3.7G speeds. 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 EV-DO Rev 0/1xRTT. The Cisco 819 3G includes
an integrated WLAN access point and has two hardened and un-hardened variants:
●
Global System for Mobile Communications (GSM) and UMTS models are based on the Third-Generation
Partnership Project (3GPP), and they support HSPA+ (High-Speed Uplink Packet Access [HSUPA] and
High-Speed Downlink Packet Access [HSDPA]), UMTS, EDGE, and GPRS.
●
Code Division Multiple Access (CDMA) models are based on 3GPP2, and they support EV-DO Rev A and
Rev 0 and 1xRTT.
The Cisco 819 ISR family includes a broad range of enterprise-class features including:
●
Security services, including firewall, intrusion prevention, VPN and Cisco ISR Web Security with ScanSafe
which require no additional hardware or client software, This enables branch offices, manufacturing sites,
