It's been a long time coming, but after countless delays in getting the auction underway, bidding on nationwide 3G spectrum in the world's second most populous market has ended -- and four companies appear to have come out on top. Most of the Indian markets only had three licenses available, so you'll likely be doing some roaming if you travel much, but Reliance, Bharti, Aircel, and Tata have all come away with significant swaths of airspace. And how much did it end up costing for the privilege of delivering high-speed wireless 'round these parts? After kicking off India-wide bidding for one slot at 35 billion rupees (about $773 million), the auction wrapped up at 167.51 billion rupees ($3.7 billion) after some 183 rounds of bidding in just over a month. Now, the hard part: actually building those 3G networks. Chop chop, guys!
