What is the flagging economy going to do to your very ambitious plans for a national WiMax wireless rollout with Sprint and other investors? The great news is that we've got $3.2 billion of cash coming in. If that sounds like a lot, it is. We can last a long time on $3.2 billion. We don't have a huge amount of pressure to go out and get additional financing.

We're well positioned to ride out the financial market storm. It would be different if we didn't have the [deal] with Sprint, Google and the cable companies for a joint venture to build the network.

What will it cost in total to build a national WiMax network? Close to the $7 billion range. But it's still a dramatically lower cost than what you've seen in traditional cellular builds. And there are good reasons for that. We are using a flat, Layer 2 IP network architecture, much more simple than what you see in traditional cellular. Also, the equipment that goes on the cell tower is smaller, lighter, more compact. The costs are dramatically less.

What impact will the poor economy have on WiMax? Will a person in danger of losing his job pay for it? If you add up the cost for residential broadband for Internet [and] residential voice service, and then add on mobile Internet and mobile voice service, the average household today spends $150 to $300 per month. If Clearwire can offer you all those services for $100 to $125 a month -- and that includes each of four people in your house with his own phone number that will work on any device, including the home phone -- I think that winds up being a value proposition. And it will be a better experience.

The deal for the joint venture with Sprint closed Dec. 1. How is the integration going? Integration efforts bringing the two teams together are going very, very well. It is a big task. Challenges that mergers traditionally have include bringing the teams together. Clearwire has about 1,800 people, and Sprint has about 700 at . It is not a small undertaking, but not as cumbersome as some mergers.
