3G Wireless WAN EHWIC Overview
The EHWIC-3G-EVDO-xcard 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-xcard supports the ISR G2 platforms (the Cisco 1900 series, the Cisco 2900
series and the Cisco 3900 series).
The EHWIC-3G-EVDO-xcard 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-xis the Cisco part number for which the interface card is configured and xis 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.

Connecting Cisco EHWIC-3G-EVDO-xto the Network
Prerequisites
Before you connect, make sure you have done the following:
•Make sure you have subscribed to an appropriate CDMA service plan with your wireless service
provider.
•Choose an antenna that best suits your needs. See the “Connecting an Antenna to
EHWIC-3G-EVDO” section on page 6.
•Although not required, you can use two antennas to take advantage of the diversity antenna mode
for the best RF performance.
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.
•To connect a diversity GPS antenna to the diversity antenna connector on the card, you need to make
a separate order for the antenna from Cisco.
•Contact your carrier for information on network coverage, signal strength, choosing a suitable
antenna, and antenna placement.
Note The diagnostics port is to be used as an advanced diagnostics tool. Do not use this port for
normal operations.
Restrictions
Limitations of 3G wireless EHWIC cards include the following:
•The 3G wireless EHWIC card must be installed in an EHWIC slot. To determine which slots on your
platform support HWICs, see the Cisco Interface Cards for Cisco Access Routers guide:
http://www.cisco.com/en/US/docs/routers/access/interfaces/ic/hardware/installation/guide/oview_i
c.html
•The 3G wireless EHWIC cards are only supported on ISR G2 platform

Wireless Access Devices Safety Guidelines and Warnings
The following are guidelines for wireless access devices:
•Do not touch or move antenna(s) while the unit is transmitting or receiving.
•Do not hold any component containing a radio so that the antenna is very close to or touching any
exposed parts of the body, especially the face or eyes, while transmitting.
•The use of wireless devices in hazardous locations is limited to the constraints posed by the local
codes, the national codes, and the safety directors of such environments.
Warning Before working on a chassis or working near power supplies, unplug the power cord on AC units;
disconnect the power at the circuit breaker on DC units. Statement 12
Warning When handling the EHWICs and antennas, wear grounding wrist straps to avoid ESD damage to the
card. Do not directly touch the backplane with your hand or any metal tool, or you could shock
yourself. Statement 94
Warning Do not operate your wireless network device near unshielded blasting caps or in an explosive
environment unless the device has been modified to be especially qualified for such use.
Statement 245B
Warning In order to comply with FCC radio frequency (RF) exposure limits, antennas should be located at a
minimum of 7.9 inches (20 cm) or more from the body of all persons. Statement 332
Warning This equipment must be connected to an indoor antenna only. Statement 373
Warning Do not work on the system or connect or disconnect cables during periods of lightning activity.
Statement 1001
Warning Read the installation instructions before connecting the system to the power source. Statement 1004
Warning Ultimate disposal of this product should be handled according to all national laws and regulations.

Prerequisites for Connecting Antennas
This section contains information about connecting the antennas.
Note Before you connect the antennas, install the 3G wireless EHWIC in the router. For more information,
see the Installing Cisco Interface Cards in Cisco Access Routers guide:
http://www.cisco.com/en/US/docs/routers/access/interfaces/ic/hardware/installation/guide/inst_ic.html
In addition to antenna orientation, installation location with respect to other wireless equipment and
other RF noise sources, such as telecom and datacom equipment, plays a significant role in determining
overall network performance.
Because antennas transmit and receive radio signals, their performance can be adversely affected by the
surrounding environment, including distance between the EHWIC antenna and cellular base station,
physical obstructions, or radio frequency (RF) interference.
Follow these guidelines to ensure the best possible performance:
•Wherever possible, mount the 3G wireless EHWIC antenna away from physical obstructions.
Barriers along the line of sight between the EHWIC antenna and cellular base station will degrade
the wireless radio signals. The 3G wireless HWICs and antennas can be installed above floor level
in office environments or near the ceiling for better performance because most obstructions tend to
be near floor level.
•The density of the materials used in a building’s construction determines the number of walls the
signal must pass through and still maintain adequate coverage. Consider the following before
choosing the location to install your antenna:
– Paper and vinyl walls have very little effect on signal penetration.
– Solid and precast concrete walls limit signal penetration to one or two walls without signal
degradation.
– Concrete and wood block walls limit signal penetration to three or four walls.
– A signal can penetrate five or six walls constructed of drywall or wood.
– A thick metal wall or a wire-mesh stucco wall causes signals to reflect back and causes poor
penetration.
•Avoid mounting the antenna next to a column or vertical support that could create a shadow zone
and reduce the coverage area.
•Keep the antenna away from reflective metal objects such as heating and air-conditioning ducts,
large ceiling trusses, building superstructures, and major power cabling runs. If necessary, use an
extension cable to relocate the antenna away from these obstructions.
Caution Install the EHWIC card and any antennas away from appliances that share the same frequency bands.
Microwave ovens, cordless telephones, and security monitors can temporarily interfere with wireless
performance.
Caution We recommend you avoid installing wireless antennas in or near rack-mounted installations that include
networking equipment and computer servers whose radiated noise emissions can severely degrade radio
performance.

Note If the desired installation site has a marginally acceptable level of radiated noise emissions, consider
using a remotely-mounted antenna, such as a wall-mounted or ceiling-mounted antenna, for better radio
performance and coverage.
