Nikon d200 wireless connection?

Is it possible that I can have a wireless connection from my Nikon d200 to "Nikon camera control 2" instead of using USB? If so, how?

Yes.

Nikon sells the WT-4A wireless "tether," which costs about $800. That will do the job.

Or if you're handy, you can make your own for about $40:
