CBRS is interesting, but there isnt a ton of spectrum available (80-150Mhz, depending on how you count it). Its also of sufficiently high frequency (3.55-3.70 GHz), that building penetration should be close to zero. Some interesting applications might come from it, but it shouldn't vastly change the game compared to what can be done with 2.4 & 5GHz unlicensed frequencies now.
