It's incredible hard to get any kind of radio signal with 60,000+ people all trying to do the same thing.
I've had no problems making calls or texting.
The wifi for the hand-held devices they used to rent out worked perfectly.
That wasn't (since they don't support them anymore) WiFi. The FanVision handhelds and their older versions all used a low powered UHF signal. As far as I know, CLink has no WiFi. There is/was a big push to get WiFi into all the stadiums, but they fell short of that goal this offseason at CLink. We are supposed to have it next season.
Wilson is the worst QB I have seen as a Hawks fan. And I have been around long enough to see them all.
