The previous changes didn't really render stuff unusable in our area. I believe it affected more dense areas a lot more. With this 600mhz being used for what looks a T-Mobile broadband how will that work? Is the whole range going to be getting blasted with RF or certain bands again? What does that leave us with? 500mhz? Will that even be possible to run large quantities in that tight of a space? From what I remember 2.4ghz was running into issues with large audiences overcrowding pinging receivers.
