Google is bidding on the WiMax area that 700Mhz is targeting within. Clearwire [founded by McCaw Cellular/later AT&T Wireless] is in on the same bandwidth.
Come the auction time, Google will have a war chest of funds to take that auction.
AT&T is buying a portion of spectrum to make sure their customers aren't cut out.
They are spreading themselves thin financially, so is Verizon and Sprint, not to mention T-Mobile with their enormous expenditures on their last auction.
correct me if i'm wrong, but aren't HIGHER wavelengths the ones that penetrate obstructions, that's why good old 5.2 and 2.4 GHZ cordless phones are clearer than 900mhz cordless phones, and why 700 mhz is better than 450, but not 1800, etc etc etc?
No... all else being equal (tower distance, power, handset used), higher frequencies penetrate buildings/walls LESS well than lower freqs. In fact, this is something that 'all-PCS' band carriers like Sprint and T-Mobile regularly get dinged on, 'cuz the 1900 MHz signal on their native networks doesn't give some customers good indoors reception, as compared to the 850 MHz 'cellular' band that carriers like Verizon and ATT often have (though they have some 1900 MHz towers as well).
However, you do get some of that nice wall-penetrating lower freq coverage even with PCS-band carriers, via their roaming partners... if you're in an area where your PCS-band carrier doesn't have native coverage.
Far as your cordless phone example goes, I suspect the newer high-freq phones sounded better because they're digital, while the old 900 MHz cordless phones were often analog.
This Picture from the article seemed to sum it all up for me...
No wonder AT&T is salivating at the thought of getting into this spectrum. Better coverage, for a lot less money. Even if the costs are a bit high up front to actually buy the spectrum.

Why 700MHz? Doesn't sound like GSM.

Google is going to own that piece.

This nice article explains the benefits/uses of the 700Mhz spectrum:
