As a musician and audio engineer, it's still a giant rub when I see TMobile or any company using the 600 mhz bands. For years and years we spent tens of thousands of dollars for state of the art wireless microphones and wireless in ear monitor systems in the 600 and originally 700 mhz range. The government comes in and lies, telling us those frequencies are needed for first responders and it a year it will be illegal for you to use that equipment. Come to find out, they are selling it off to the highest bidder. It cost me over $15,000 just to comply for one band. More than a little frustrating and different perspective on that "sweet 700mhz" ....
I think we'd had this talk back when 700mhz was first deploying. Oy vey! What new frequency are they pushing you guys on to now?
