The redesign was caused by changes in
cordless phones, not cell phones. My understanding is that the old modems used a module out of a 900MHz cordless phone, and those are practically non-existent now, having moved to 2.4 and 5.8GHz. I'm guessing you don't see teams using cordless phones near the robot too often
For what it's worth, we got our repaired modems back from IFI yesterday and the RC side was marked as having v6 firmware. The difference was night and day. They now seem to work just as well as the old modems. I even buried the modem down inside the frame of our practice bot and mounted it horizontally to see how it held up, and it worked great. Didn't see any dropouts all night. I think this is a good sign that IFI now has the problem well under control.
