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

Statement 1040
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.

Connecting an Antenna to EHWIC-3G-HSPA-U and EHWIC-3G-HSPA+7/-A Cards
Caution
Install the 3G wireless EHWIC 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.

Connecting Swivel-Mount Dipole Antennas
If you are using Cisco swivel-mounted dipole antennas, follow these steps:
Step 1
Attach an antenna to each TNC antenna connector on the front of the EHWIC card and tighten it
hand-tight.
Step 2
Orient the antennas, depending on how you intend to mount the router in which the card is installed.
Note
•
If the router is on a table or desk, orient the antennas to the left and right sides so that they are at a
90-degree angle to each other. (See Figure 13.)
•
If the router is on a vertical surface, such as a wall, orient the antennas up and at a 90-degree angle
to each other.
•
If the router is on a ceiling, orient the antennas down and at a 90-degree angle to each other.
Although it is not absolutely necessary, for best RF performance, do not attach the dipole antenna
directly to the face-plate of the card. Use the antenna extension cable and antenna base recommended
for the product.
Faceplate-Mounted and Ceiling-Mounted Antennas and Cabling
Depending on the wireless environment, wall-mounted or ceiling-mounted antennas may be preferred
for optimum radio coverage. If the length of the coaxial antenna cable is insufficient to cover the distance
between the EHWIC card and the location of the installed antenna, you can use ultra-low-loss TNC
extension cables between the EHWIC card and the antenna cable.
RF energy is carried between the antennas and the radio equipment through a coaxial cable. An antenna
cable introduces signal loss in the antenna system for both the transmitter and the receiver.
Although the cable run can be 100 feet (30 m) or more from the EHWIC card to antenna locations, the
longer the cable run, the greater the signal loss. To reduce signal loss, minimize the cable length and use
only ultra-low-loss antenna cables to connect radio devices to antennas.
To connect faceplate-mounted or ceiling-mounted antennas, follow the installation instructions for your
antenna:
