the changes are known, i figured it out early this morning and posted it to the apple discussions board for the airport. it never occured to these apple journalists to actually go to the fcc website and actually read the report
the new airport extreme features 2.81 x the maximum power output then the previous model.
i tried emailing crunch gear john and tips @ venturebeat about the actual difference i found but i guess the emails got lost as they always do.
i have read a lot of posts with people and always accusing apple of releasing wireless routers with low power (like 100 mw) and it looks like this time apple finally listened to us
there was a link on the news reports about a fcc database so i decided to look at the report and search the database for a prevous airport model
i found an airport model a1354, i believe this is the mc340ll model. this is what it says on test results:
frequency range / mode / output power dbm / output power milliwatts
2412-2462 802.11b 24.57 286.42
2412-2462 802.11g 21.56 143.22
2412-2462 802.11n(ht20) 21.17 130.92
5745-5825 802.11a 23.07 202.77
5745-5805 802.11n(ht20) 22.17 164.82
5755-5795 802.11n(ht40) 21.44 139.32
you compare this to the report of the newer model and these numbers are provided:
2412-2462 802.11b 24.10 257.04
2412-2462 802.11g 24.88 307.61
2412-2462 802.11n(ht20) 24.11 257.63
5745-5825 802.11a 25.14 326.59
5745-5805 802.11n(ht20) 25.28 337.29
5755-5795 802.11n(ht40) 25.94 392.64
ht 40 means 40 mhz wide mode
so based on tbhese numbers there is a improvement of 2.81x in terms of power output of the new md031ll model versus the older mc340ll model.
