Just to make it clear - current "unlicensed" LTE technologies are LTE-U and LAA require an "anchor" channel in a licensed band. I.e. you still can't run it in your home unless you have a license for one other spectrum band. It's still limited to a carrier play, unfortunately. There is MuLTEfire tech by Qualcomm which can supposedly work completely in unlicensed spectrum, but it's proprietary and not very much is known about it so far.

Yeah no. This isn't LTE that anyone can set up, like WiFi. It's more designed to improve the speed of licenced LTE by letting LTE femtocells use unlicenced bands.

Also only the downlink is done over unlicenced bands. There's a competing standard that does uplink and downlink, but the all just augment a licenced LTE connection.

Any details on handset availability (even rumors)? I'd love to get my hands on a phone with an LTE transceiver that can operate in this spectrum range having an unlocked bootloader on the application processor.

Setting up a base station at elk camp and being able to use a regular cell phone instead of a dedicated amatuer or FRS/GMRS transceiver would be very cool.

Sorry, I don't know when this stuff is coming. In the mean time you could just use a wifi network with a SIP server for voice calls.

How is that going to work? I thought 5GHz had really poor penetration and attenuation. Will it trash wifi performance?

The cell carriers are mainly planning to use the 5GHz band for small cell indoor deployments (distributed antenna systems). The 3GPP and the Wi-Fi Alliance are going back and forth to ensure that if LTE and Wi-Fi networks are forced to share the same channel that it will at worst degrade the Wi-Fi performance as if there were another Wi-Fi network sharing the channel.

Unfortunately that's not true in implementation because LTE-U doesn't know or care about the wifi channel announce timings. By piping up whenever it wants to wifi throughput actually degrades more than 70% at minimum LTE-U duty cycle spec (50%) and up to almost completely, ~99% reduction, at max allowed LTE-U duty cycle (90%) spec.

No matter what they say this is a spectrum grab and LTE-U will degrade 5 GHz wifi to the point of being unusable.
