There's a few issues with that. You would be basically looking at two separate configurations (to an extent) on your robot. You would have to manage a second network, and while it may not be hard, I don't think technology is not that good enough (correct me if im wrong) or cheap enough or not as complex to do that reliably, and quickly.

One of the issues with the field (possible issue) was the amount of 3G traffic going on and other potential Wireless Networks, if you have those networks right on the field, you could add quite a bit more issue to the mixing and messing up of the wi-fi networks.

Also, all suggestions are welcome, only way you or I will ever learn. You should be proud to just even think about this being a mechanical "dude". It shows that you're interested in finding solutions and not doing your "job". Good for you!
