yeah, this is bob barnett in chicago. (john foley) i was there when bob barnett made the first commercial wireless phone call. we were both working on that first network that would eventually become verizon's. that call opened the door to the billions of mobile calls that we've all made since. i'm proud i was part of that first call, and i'm proud that i'm here now as we build america's first and only 5g ultra wideband network that will transform how we all live, once again. (bob) the first call that we've made on the cellular system.
