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.
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.
Channels 1,6 and 11 are independent and do not overlap each other. It is
recommended to tune your WiFi-b™ card to these channels.
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.
