A+ Question of the Week

Which wireless networking standard has a theoretical maximum data rate of 54 Mbps and operates at a frequency of 2.4 GHz?

1. Bluetooth version 3.0
2. IEEE 802.11a
3. IEEE 802.11b
4. IEEE 802.11g

The correct answer is 4.

The 802.11g standard uses a 2.4 GHz radio and can attain speeds as high as 54 Mbps. The 802.11a standard can also attain such speeds, but it uses a 5 GHz radio. Like 802.11g, Bluetooth 3.0 and the 802.11b standard employ the 2.4 GHz radio, but they only attain speeds as high as 24 Mbps and 11 Mbps, respectively.
