DBA will run the same on a Wireless LAN as it would on a Wired.  It can't tell the difference.

We use a wireless network for PC's on the shop floor running DBA. It works great now, but about two years ago when we originally set up the system, we were using equipment based on 802.11b (11mbps) technology. This was far too slow and caused many problems, we have since upgraded to 802.11g (54mbps) technology and it has made all the difference in the world. Now DBA runs smoothly on those machines. I would highly recommend using equipment that offers an accelerated mode, for instance U.S. Robotics has an 802.11g access point/router that will connect at 125mbps as long as you have their accelerated adapter on the PC. The connection speed will make a big differance. Another suggestion would be to choose an access point/router that gives the flexibility of changing the antenna. Some of the units have un-attachable antennas and you are stuck with the range and signal that you are getting.
 
You can also do all of this really cheap if you shop around, they are always offering mail-in rebates for this type of equipment. I was able to set up two access points and 4 PC's on 125mbps wireless network for under $150.00.

Security's a problem?!
 
We've been putting machines on the shop floor for a month now and we hard code the MAC addresses into the Wireless Access Point.  That way it will ONLY connect with our machines.  No way to hack in unless you can manage to spoof the MAC address!  Kind of a pain for a bunch of machines, but so far we're only up to 5 wireless units and the res are hard wired.  Biggest pain for us is having two WAP's and thus having to add the addresses to both of them!
 
You definitely want 802.11g for the speed.  Depending on your plant layout and the type of manufacturing, your signal strength and throughput can vary a lot.  We've got al sorts of welders sending out electrical interference, thus the multiple WAPs.
 
Best of luck to ya'
