It’s official: Google has declared its intent to take part in next January’s auction of the 700 Mhz frequency spectrum. The company also plans to make a go of it alone and without a partner in mobile industry despite the $4.6 billion USD starting bid. Google will use the new spectrum for the recently introduced Android platform, which could make telephone calls and surfing free (well, almost free) with Google’s earnings coming from mobile services and sponsored links.
