At both NJ and Buckeye, we had streaming video (30 fps) of the field from the stands down to the pits over 802.11a (although 802.11g would be equivalent). The issue is how far you need your wireless link to be. Line of sight and under a mile, 802.11a/g would be a good choice. Further, consider 802.16 gear.

Your serial modems would be poor at best, 19k2 just isn't fast enough* for video. 56k maybe, 128k no problem, 320k is what the Champion Webcasts were running. The encoding (which introduces loss and distortion) and the image size both affect bandwidth requirements, and wider bandwidth affects how far you can go wirelessly.

Note that Ham Radio can do all this, too, with far fewer pesky power and antenna limits...

*Yes, it can be done, but not well.
