Thank you very much to all the witnesses.
Mr. Ghiz, you talked about 5G technology. Earlier this morning we were speaking about Internet connectivity and considering it as critical infrastructure that is central to this country's future, particularly its economy and certainly its competitiveness. You're the first person who has brought 5G to the discussion. This is really exciting stuff; there's no question about it.
Where exactly are we in 5G? My understanding is that it's still in its infancy in terms of the development of the technology, is it not?
