Installation Notes
This Cisco Multi-purpose Integrated Antenna is designed to be mounted directly onto the router.
In addition to antenna orientation, wireless access point installation location with respect to all wireless clients 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 Field Area Router (FAR) and cellular base station, physical obstructions, or radio
frequency (RF) interference.
Follow these guidelines to ensure the best possible performance:

Install the router with antenna without physical obstructions. Barriers along the line of sight between the FAR and cellular
base station degrade the wireless radio signals.

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 degrading coverage.
— 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 wire-mesh stucco walls causes signals to reflect back and cause 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 router and antenna away from appliances that share the same frequency bands. Microwave ovens,
cordless telephones, and security monitors can temporarily interfere with wireless performance.
CAUTION : 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
remote-mounted antenna, such as a wall-mount or ceiling-mount antenna, for better radio performance and coverage.
