Alexander,as you might imagine, conceptually there is no disagreement whatsoever here ;-) And, in fact, that already exists on some platforms, but it's somewhat limited at the moment due to lack of support for standards body/bodies at this time. But I'm hopeful that we're closer to meaningful improvements. This is just as important for managing the available spectrum as it is for device power efficiency.

Another mobile-land feature 802.11 could do with - dynamic TX power management. All the cellular systems have the ability to dial down the transmitter power the nearer to the BTS/Node B you get. This is not just good for batteries, but also good for radio, as s/n has diminishing returns to transmitter power. WLAN, though, shouts as loud next to the AP as on the other side of the street, which is Not Good for a system that operates in unlicensed spectrum.UMTS, for example, has a peak tx wattage an order of magnitude greater than WLAN, but due to the power management, in a picocell environment comparable to a WLAN the mean tx wattage is less by a factor of 10.
