mr. gillen? mr. berry. >> yes, senator, i agree that we do want to be in first because we get the first mover benefit in the economy. i'm also concerned about as we move to 5g that we're also ready for 5g in all of rural america. we need to get to 4g lte, the faster we get there, the faster we can have the benefits in rural america and urban suburban america of the 5g world. i don't think we want to leave half the united states or half the nation behind this economic opportunity for the new mobile world. and so that's my concern. yes, we need to be on the forefront of innovation, but we also need to do it in a way that allows the entire economy to benefit from this great opportunity. >> thank you very much. well, mr. berry, let me ask you, then, to elaborate, on the concern that i expressed, and that you expressed about data collection, and broadband mapping. i think you said it's just -- it's just totally inadequate. so if you'd comment on that first, and then if anyone else would like to follow up,
