However, they'd also mitigate problems for just about everyone -- you wouldn't have to worry about your smartphone's data bogging down in a busy part of town, or watch nearby networks interfere with your drone flight. Wireless technologies like 5G or unlicensed cellular could become that much more practical, as you wouldn't see their potential wasted by arbitrary spectrum rules.'
