I'm pretty sure the robot control data doesn't take more than about 1KB per update, at around 50 Hz. This gives you 400 Kbps for robot control data.

To transmit a single frame of video with 320x240 resolution and 24bit color is 320*240*24 = 1.8 Mb. Note that the Axis cameras use MJPEG compression as well, so this is a gross overestimate. For targeting purposes, given the network lag that's going to be inherit in the system, you shouldn't need more than 10 fps. Maybe 15 if you want smoother-looking video for display to your drivers.

That's still only 30 Mbps (even with uncompressed video).
