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.

The EHWIC-3G-EVDO cards support multiple bands and services:
• 800/1900 MHz for 1xRTT
• 800/1900 MHz for 1xEVDO Revision 0 and Revision A
• Standalone GPS
• Short Message Service (SMS)
EHWIC-3G-EVDO-x is the Cisco part number for which the interface card is configured and x is a
variable representing carrier-specific versions.
The EHWIC-3G-EVDO versions currently available are:
• EHWIC-3G-EVDO-B (BSNL)
• EHWIC-3G-EVDO-S (Sprint)
• EHWIC-3G-EVDO-V (Verizon)
Additional carrier-specific versions may also be available. See the onboard Product ID (PID) sticker to
differentiate between released versions.
The EHWIC-3G-EVDO cards support diversity mode (dual antenna mode) in the antennas. Types of
antennas include swivel-mounted dipole with extended base and ceiling-mounted antennas. The
diversity mode requires two antennas located together and spaced a minimum of 7.5 inches (19 cm) for
better RF reception.

Note To use the GPS feature, connect a GPS antenna to the Diversity/GPS Antenna Connector. To use the
Diversity feature, connect a Diversity antenna to the Diversity/GPS Antenna Connector. You cannot use
the same antenna for both features.

Default Antenna and Antenna Extension
EHWIC-3G-EVDO cards ship with the default antenna (3G-ANTM1919D) and the default antenna
extension, a base with a 10-foot cable (3G-AE010-R):
• Cisco Multiband Swivel Mount Dipole Antenna (3G-ANTM1919D) antenna
• Cisco Single-Port Antenna Stand for Multiband TNC Male-Terminated Portable Antenna
(3G-AE010-R) antenna extension
Note The 3G-AE010-R antenna extension is the same as 3G-AE015-R except for the length of the
antenna cable. The 3G-AE015-R antenna extension comes with a 15-foot cable.
Connect the default antenna to the main antenna connector on the EHWIC card. If you need to move the
antenna to a better location, connect the antenna to the extension and then connect the extension’s cable
to the main antenna connector on the card.
Figure 2 shows the Cisco 3G-ANTM-1919D multiband swivel-mount dipole antenna connected to the
Cisco 3G-AE010-R antenna extension.
