Hardware Features

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.

The Cisco 88xG 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 ISRs data sheet.

Wireless LAN Connectivity

The embedded wireless access point is preinstalled in the router as an optional feature. The wireless access point provides 802.11n wireless connectivity. The Cisco 860 series routers support autonomous features and network configurations. The Cisco 880 series routers support both autonomous and unified features and network configurations.

The wireless access point does not have an external console port for connections. To configure the wireless device, you must use a console cable to connect a PC to the host router’s console port as described in Chapter 3, “Connecting a Terminal or PC to the Console Port,” and then use the Cisco IOS CLI to access the interface.

Table 1-2describes the radios and antenna for the Cisco 860 series and Cisco 880 series routers.
