Making the jump to light speed



Which of these wireless network standards support maximum throughputs of over 50 Mbps? Pick three.

A) 802.11a

B) 802.11b

C) 802.11g

D) 802.11n

E) Wait a second; don’t all radio waves travel at the speed of light?


The answer: A) 802.11a, C) 802.11g, and D) 802.11n

802.11b uses similar frequencies as 802.11g, but the older wireless standard is only designed for a theoretical maximum throughput of 11 megabits per second.

And yes, I realize that radio waves only travel at the speed of light in a vacuum.
