mr. hatfield?ank you. i think it's -- >> could you pull that microphone just a bit closer. >> i think there's sharing if you look at in two ways. it's important. we avoid a share in a lot of the existing spectrum. we call that static sharing. for example, an antenna pointed at a satellite are pointing in different direction. that provides sufficient isolation that a satellite system can share with the terrestrial system. that static sharing has been bus for quite some time and used effectively. i think the key here is combining the concept that tom talked about. at the time today, look at more dynamic forms of sharing. for example, you're in town today, and d.c., particular channel might not be used by some private microphone, something like that. that spectrum could be shared on a dynamic basis. i think the key going forward -- >> so you are not talking about technology. that would allow dynamic sharing. >> given that opportunity, talk a little bit if you would about the state of technology develo
