Operating Temperature
Note 1: Temperatures above +80°C reduce wireless performance. Module operates from -40°C cold start.
The Communications Card is designed to prevent damage to sensitive components due
to electrostatic discharge during normal operation; however, when handling the card take
proper static-control precautions to prevent damage.
CAUTION
Optimize Your Wireless Network
For the best wireless coverage, consider where you place the access point, where you place the adapters, and
how you adjust the antennas. Some recommendations are:
Position the access point in line of sight to the wireless adapters, and in a central location within the area
to be used for wireless communications. Try to position the access point in a place that is higher than
networked computers and equipment.
Position the access point away from other radio equipment operating at a frequency of 2.4 gigahertz
(GHz), such as microwave ovens and cordless telephones.
Keep your wireless equipment away from large metallic objects, such as computer cases, display
monitors, and appliances, as well as other electromagnetic devices, such as televisions, radios,
cordless telephones, and microwave ovens that might interfere with wireless transmissions.
Position your wireless equipment so that large masonry structures, such as fireplaces, are not obstructing the
radio path. Building construction, such as metal framing, ultraviolet-resistant window film, metallic paint,
concrete or masonry walls, or multiple floors and walls reduce radio signal strength.
