Well...
On the one hand, I'm not a fan of having cell cos use an unlicensed band, potentially crapping it up for other uses, to provide LTE at the high per-GB rates they charge. On the other hand, I suppose where these would be located, well, a warehouse or something that may run 5ghz wifi just wouldn't have an LTE cell in it too, and it's not too likely you'd end up with one outside your place interfering with home use.
I *would* be interested in the possibility of using LTE on 5ghz to just provide data service in general (i.e. like an "LTE access point" instead of wifi), I'd be interested to see how 5ghz LTE holds up against 802.11n or 802.11ac in terms of performance (especially under load.)
