URGENT! Time Capsule and AirPort Extreme (2009 models). Which has better WiFi range?

Hi guys,

I own an AirPort Extreme dual band (2009 model) and I've the chance to sell it and buy a Time Capsule 1TB (2009 model too) for 160€, so the question is: which has better range over 802.11n and 802.11g?, or they've the same?

I ask this because I suppose that Time Capsule has a smaller network board/card due to the internal HDD occupying the most part of the case, so this may affect the range, but maybe I'm saying the stupidity of the year, LOL.

Anyone with both, TC and AEBS, can bring me some light about this?

Thanks in advance,
Daniel.

Up!
