802.11a Channel Frequencies
The available 802.11a Channels varies by regulatory domain and/or country. 802.11a radio certification is available in 
the following regions:
FCC: U.S., Canada, and Australia
ETSI: Europe and the United Kingdom
TELEC: Japan
SG: Singapore
ASIA: China, Hong Kong, and South Korea
TW:  Taiwan
There are five sets of frequency bands that determine the available channels depending on the regulatory domain.
Some countries restrict 802.11a operation to specific frequency bands. The Web interface and CLI display the 
available channels for a radio's particular regulatory domain. In the CLI, any channels that are not available are labeled 
"Not Supported". 
NOTE
The original 5 GHz Upgrade Kit only supports the Lower and Middle U-NII bands. The 11a Upgrade Kit 
supports all of the frequency bands described below.
Note 1: Channel 34 is the default channel for Japan
