WiFi range: How far do the different standards go?

WiFi range: How far do the different standards go? Comparing wireless a,b,g,N: is there a noticeable difference in the coverage area provided by each of the different standards? Do any of them do a better job penetrating different kinds of walls (namely concrete block)?

"Wikipedia has a table of the various protocols and their approximate ranges.

A - indoor 35m (outdoor 120m)
B - indoor 38m (outdoor 140m)
G - indoor 38m (outdoor 140m)
N - indoor ~70m (outdoor ~250m)

There is very little difference between A, B and G and it is likely that you will find transmitter/receiver quality will play a far bigger role in the range you can actually achieve.

N however, specifically added features that increased the potential range - see this article"
