Carriers Are Hoarding America’s Bandwidth. Google Just Wants Them to Share

A Google-led plan to overhaul how valuable airwaves are used for calls and texts is gaining momentum across the wireless industry, giving the company the chance to play a central role in networks of the future. Citizens Broadband Radio Service, or CBRS, is a fat slice of the US airwaves being freed from the military’s exclusive control. Instead of just zipping messages between aircraft carriers and fighter jets, the spectrum will be shared by the Navy, wireless carriers like Verizon, cable companies including Comcast, and even hospitals, refineries, and sports stadiums. Google, with help from some smaller tech companies, is leading the charge on ways to make the new service work seamlessly. They've built databases and sensor systems that switch users to different CBRS channels to avoid interference, especially when the Navy sails into town. This could upend the wireless business. Carriers spent more than $50 billion in recent years buying exclusive spectrum rights then charging users for cell service. What if, instead of buying and hoarding, spectrum is shared in new ways? It could become an abundant resource, making mobile internet connectivity more available and potentially cheaper.
