A.2 Channels
The IEEE 802.11b standard for Wireless LAN allocated the 2.4 GHz frequency
band into 14 overlapping operating channels. Each channel corresponds to a
different set of frequencies. The table below shows the center frequencies of each
channel.
The number of channels available for the WiFi-b™ varies by country/region. Refer
to the table below to determine the number of channels available in your location.
Country/Region (Regulating Body) Available Channels
Australia (ACA) Channels 1 to 13
Belgium (RTT&E/EMC/LVD) Channels 1 to 13
Bulgaria (RTT&E/EMC/LVD) Channels 1 to 13
Canada (CSA/cUL 950 3rd Edition) Channels 1 to 11
China (MII) Channels 1 to 11
Cyprus (RTT&E/EMC/LVD) Channels 1 to 13
Czech Republic (RTT&E/EMC/LVD) Channels 1 to 13

If several WiFi devices are operating in the same vicinity, the distance between the
center frequencies of channels used must be at least 25 MHz to avoid interference.
