Appendix A: Radio Channels and Frequencies
Rajant's BreadCrumbs can contain up to four radios. 802.11g radios are used in the 900 MHz and 2.4
GHz bands, and 802.11a radios are used in the 4.8 GHz, 4.9 GHz and 5 GHz bands. The radios support
the channels and frequencies listed in the following tables for use in the United States and Canada.
Note
Not all channels are allowed for use everywhere around the world. Check with the
corresponding wireless spectrum regulatory body to determine the subset of channels
authorized for use in your country.
Caution
Since the radios operate at different frequencies, you must be careful to use the correct
type of antenna with each radio. As an example, a 2.4 GHz antenna will not work with
a 5 GHz radio and vice versa.
