Cisco C891 Series ISRs

3G Cellular Data WAN Connectivity

The 3G (Evolution Data Only [EVDO], Universal Mobile Telecommunications Systems [UMTS]) cellular interface is intended for use as a backup data link, but it can also be used as a primary WAN data link. The 3G technology is third-generation wide-area cellular technology that is used in voice telephony and broadband wireless data in a mobile environment.

Some Cisco 880G models come with a 34-mm express card slot ready for use with a commercial 3G card radio. The 3G express card slot is located on the front panel. For a list of supported 3G cards, see the Cisco 880 Series Integrated Services Routers Data Sheet.

Other Cisco 880G models come with embedded WAN modems for use over GSM or CDMA networks. These routers have antenna connectors on the back panel. GSM routers have two SIM card slots. For information on configuring Cisco 880 series ISRs for 3G, see Configuring Cisco EHWIC and 880G for 3G (EV-DO Rev A) and Configuring Cisco EHWIC and 880G for 3.7G (HSPA+)/3.5G (HSPA).

Wireless LAN Connectivity

The embedded Wi-Fi CERTIFIED™, 802.11a/b/g/n-compliant wireless AP is preinstalled in the router as an optional feature. The Cisco 860 series routers support autonomous features and network configurations. The Cisco 880 series and 890 series routers support both autonomous and unified features and network configurations.

The wireless AP does not have an external Console port. Use the router’s Console port as described in Chapter 3, “Connecting the Router.” To configure the wireless device, use the Cisco IOS command-line interface (CLI).

Table 1-35describes the radios and antennas for the Cisco 860 series, 880 series, and 890 series routers.

Note Cisco 860VAE ISRs do not support wireless LAN connectivity.

The 5-GHz radio operates in the Unlicensed National Information Infrastructure (UNII) 1, 2, 3, 5-GHz frequency bands.
