Assume that your network operates in a regulatory domain that allows use of UNII-1, UNII-2, UNII- 2e,
UNII-3, and the 5.8 GHz ISM band for indoor Wi-Fi. In your upcoming 802.11n deployment, you would like
to take advantage of the performance improvements that result from channel bonding. However, after
extensive testing, you have determined that your mission-critical WLAN should not use channels requiring
DFS support.
Given those two criteria (enable channel bonding and disable DFS channels), in the 5 GHz spectrum, how
many non-overlapping channels will your system be able to use?
