Despite some doom and gloom about WiMax, Clearwire is acting as if it is business as usual.

The Kirkland-based company said today that it launched a wireless high-speed Internet access and phone service in Charlotte, N.C. Charlotte is Clearwire's 45th market.

Clearwire is still rolling out a pre-WiMax solution (which is why I thought it was funny that an analyst in a trade journal today called Clearwire the most successful WiMax company), which is available to consumers either through a home modem, or a PC laptop card.

In fact, as far as I can tell, there's no company selling true WiMax services yet.

The news of the new market didn't exactly send Clearwire's stock rocketing. In afternoon trading, it fell $1.42, or about 19 percent, to $14.15 a share.
