Wireless Lan Connectivity - Cisco 881W - Integrated Services Router Wireless Hardware Installation Manual

Chapter 1 Product Overview
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 Integrated Services Routers

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 a Terminal or PC to the Console Port."
Cisco IOS command-line interface (CLI).
