Engineers from Verizon and some of its top tech suppliers have been huddling in a small room at the carrier's test facility in Irving, Texas, for the past few weeks staring at results pouring in on their laptops. At stake is one of Verizon's big bets to alleviate a coming spectrum crunch that could slow its wireless network in many parts of the country
After opting out of last year's federal airwave auction in the 600 MHz band, Verizon is looking for other ways to offer customers more bandwidth. The Irving test is focused on a new segment of airwaves being opened to the wireless market in the 3.5 GHz band and known as Citizens Broadband Radio Service, or CBRS for short.
