So going from a regular powered 100mw (20db) to a high powered 400mw (26db) is a 6db increase in output power. So you are saying going from regular to high powered is a double in coverage size? Doesn't increasing the power output at the AP only increase how loud the AP can "shout" which in term dictates how far the receiver can hear from? If the client can't shout back does this do any good?
Most client devices today like iPads, Smartphones, and some laptops can't be modified to increase their antenna gain or power output. So the only option is to increase the numbers of APs, or the transmit power/antennas at the AP right?
