802.11ad which has newly comeup , in yr 2009 i guess so , it uses mostly Extremely High frequency band i.e 60 GHz ( when there is no roaming ) ,when client doesn't move and the line of sight is clear b/w client and AP antenna. Using 60GHz ensures high data rates however, the Electromagnetic ( radio ) waves can't penetrate walls and cement structures ( Line of Sight is violated ) , and in that case, the communication switches down to other lower standards ( using 2.4 and 5 ghz ) which can penetrate normal obstructions like wall, therefore, the communication doesn't drop in the case client moves. However, as said while client is in romaing , the communication switches to low standards , therefore, the data rate will fall. POE would be not an issue here!! POE element has nothing to do with this high rate radio technology!

State your source, Saurav. This is not correct.
Read the data sheet for the 3700 and see how it's recommended that the AP be powered up with AT LEAST 20.0w of PoE (without modules). Also notice what happens if you only have 15.4w PoE?
Same goes with 3600 with 802.11ac modules.
NOTE: Be careful about posting incorrect (and irrelevant) information in this forum. You, Abhishek and a few others are posting with Cisco logo. When you respond with incorrect information, people look at your avatar and will think, "He's a Cisco employee, therefore he knows what he is talking about.". Pray that the person does not go and do (like purchase) incorrect parts because I sure don't want to find that person coming back and say that the solution isn't working. If you want to post incorrect information, do it with your personal account (and not your work account).
Thankyou Leo , I totally agree with you :), what I meant in that thread is the POE tech will remain same ( just more power would be needed which I skipped , my fault ) , it is quite understandable that higher frequency operation and jumps over multi standards will consume more power!!
Prasan, as Leo said, the power fed will be more here, since we can see we are operating very high frequency.The purpose is same as we have in our telecom towers!! telecom towers communicate with each other using microwaves ( high frequency ,power and less wavelength ). There also the line of sight should be clear. rays cant penetrate the obstacles.
Regarding, AP to WLC connectivity, our APs already have gig -uplinks to handle the traffic. I don't know how the traffic more than 1 gig around 7 ( 802.11ad bets ) , probably link aggregation could be the solution.
As far as Ethernet... this was tossed around at Live this year and eventually just like 802.11a/g to 802.11n went from Fast Ethernet to Gigabit Ethernet, I would think that Cisco will soon have to design a dual Gigabit AP to allow for bundling the ports. Now there was other things mentioned, but I just don't think that would happen in the near future. One was talk about 10 gig port, but cost would be too high.
