The radio frequency channels used are listed in Table 4-1:
Note: The available channels supported by the wireless products in various countries are different.
The preferred channel separation between the channels in neighboring wireless networks is 25
MHz (5 channels). This means that you can apply up to three different channels within your
wireless network. There are only 11 usable wireless channels in the United States. It is
recommended that you start using channel 1 and grow to use channel 6, and 11 when necessary, as
these three channels do not overlap.
WPA Wireless Security
Wi-Fi Protected Access (WPA) is a specification of standards-based, interoperable security
enhancements that increase the level of data protection and access control for existing and future
wireless LAN systems.
