That only works if you have Sprint. At Richmond earlier this year, I had OK coverage on Thursday (K&N and Hamlin races), then come Friday and Saturday, could barely get and 3G or 4G anywhere on the grounds. After the end of the night, as all the Sprint trucks were loaded up and leaving, 4G was plentiful in the media center, in the parking lot, wherever I went. Should be illegal.
