Specifications
802.11g Channel Frequencies
The available 802.11g channels vary by regulatory domain and/or country. 802.11g radio certification is available in the
following regions:
— FCC - U.S./Canada, Mexico, and Australia
— ETSI - Europe, including the United Kingdom, China, and South Korea
— MKK - Japan
— IL - Israel
Some countries restrict 802.11g operation to specific frequency bands. The web interface will always display the
available channels depending in the cards regulatory domain. In the CLI, any channels that are not available are
labeled "Not Supported".

Wireless Communication Range
The range of the wireless signal is related to the composition of objects in the radio wave path and the transmit rate of
the wireless communication. Communications at a lower transmit range may travel longer distances. The range values
listed in the Communications Range Chart are typical distances as calculated by Proxim’s development team for
FCC-certified products. These values provide a rule of thumb and may vary according to the actual radio conditions at
the location where the product is used.
The range of your wireless devices can be affected when the antennas are placed near metal surfaces and solid
high-density materials. Range is also impacted due to “obstacles” in the signal path of the radio that may either absorb
or reflect the radio signal.
In Open Office environments, antennas can “see” each other (no physical obstructions between them). In Semi-open
Office environments, workspace is divided by shoulder-height, hollow wall elements; antennas are at desktop level. In
a Closed Office environment, solid walls and other obstructions may affect signal strength.
The following tables show typical range values for various environments for FCC-certified products (range may differ
for products certified in other regulatory domains).
