How many non-overlapping channels are available with 802.11g?
Answer: A
Correct answer: 3
802.11g shares the 2.4 GHz band with 802.11b and so shares its channel plan: eleven overlapping channels of which only 1, 6 and 11 can be used together. The higher data rate changes nothing about the spectrum available, which is why 802.11a’s twelve channels remain its principal advantage.
