What is the frequency range of the IEEE 802.11b standard?
Answer: C
Correct answer: 2.4GHz
802.11b uses the 2.4 GHz ISM band, which it shares with 802.11g, Bluetooth, cordless telephones and microwave ovens - the source of most of the interference that band suffers. As with the 802.11a item, the two options quoted in Gbps are rates rather than frequencies and can be discarded on units.
