My observations:  the current pre-standard product suite that use the
LTE-protocol on the 5Gh band are targeting indoor, not outdoor.

All marketing and communications on LTE and 5Ghz band is around mobile
operators and their need for spectrum. From a technical perspective, I
must admit that LTE is a more efficient protocol than Wi-Fi is. So, in
addition to preventing that operators ruin the spectrum at our Wi-Fi
facilities we should also knock on the doors of our Wi-Fi vendors and
asking them how they integrate LTE-U (or another flavour) in their Wi-Fi
product offering for our benefits. Frankly speaking, I do not care
whether the radio communication uses Wi-Fi, LTE or what ever protocol as
long as it does its job well and efficiently.
