Connecting Cisco EHWIC-3G-EVDO-x to the
Network
Revised: January 2011, OL-24264-01
This guide describes how to connect the EVDO versions of the 3G wireless Enhanced High-Speed WAN
Interface Cards (EHWICs) to your network.
3G Wireless WAN EHWIC Overview
The EHWIC-3G-EVDO-x card is a multiband, multiservice WAN card. Its primary application is WAN
connectivity as a backup datalink for critical data applications and as a primary WAN connection.
The EHWIC-3G-EVDO-x card supports the ISR G2 platforms (the Cisco 1900 series, the Cisco 2900
series and the Cisco 3900 series).
The EHWIC-3G-EVDO-x card houses one cellular modem for connection to a wireless WAN.
