Your company is installing new 802.11g wireless access points in your conference room areas. What is the maximum theoretical throughput of an 802.11g wireless network?
A) 11 megabits per second
B) 54 megabits per second
C) 100 megabits per second
D) 600 megabits per second
Answer: B) 54 megabits per second
The 802.11g standard has become popular for many reasons, but one of the most compelling is its increase in speed to 54 megabits per second. Although the 54 megabit speed was already available in 802.11a prior to the release of 802.11g, the “a” standard was not widely deployed and most wireless networks were running at the slower 802.11b speeds.
The incorrect answers:
A) 11 megabits per second
The 11 megabit per second speed of 802.11b was one of the early 802.11 standards (thus the “b”). You can still see 802.11b supported on many access points because of their support for both 802.11b (11 megabits) and 802.11g (54 megabits).
C) 100 megabits per second
The theoretical throughput of 100 megabits per second is familiar to network professionals that support the many flavors of wired Ethernet.
D) 600 megabits per second
The introduction of 802.11n promises to bring much higher speeds to 802.11 wireless networks, and the theoretical throughput of 802.11n to 600 Mb/s will certainly push that boundary.
