Which WLAN IEEE specification allows up to 54Mbps at 2.4GHz?
Answer: C
Correct answer: G
802.11g runs in the 2.4 GHz band at up to 54 Mbps and is backward compatible with 802.11b, which is why it displaced it so quickly. 802.11a also reaches 54 Mbps but does so at 5 GHz, so it is not compatible with b or g equipment. 802.11b is limited to 11 Mbps, and 802.11n is faster than 54 Mbps and works in both bands.
