Re: SO many avenues, opportunities
So far, talk about 5G seems to be dominated by the usual suspects of RAN vendors and operators. But if the technology is to deliver on the visions for IoT and M2M and everything else, then I think a broader variety of companies and researchers should be involved at this stage -- from human behavioral scientists to car manufacturers, in addition to wireless engineers. How will people (and machines) actually use wireless technology in ten years, in twenty years?

One European 5G research project (METIS 2020) has BMW among its academic and telecom industry members. That's just one example, how many others are out there?

Re: LTE-U
The LTE-U debate is exciting. Sounds like some operators will need to get more comfortable with unlicensed spectrum, for sure. Whenever 5G arrives, I also wonder to what extent alternative licensing regimes will be adopted, such as shared access, to use limited spectrum resources more efficiently.

Latency
Ha! I just finished talking about latency in a comment on Sarah's VoLTE story.

Recapitulating: Philip Rosedale, who founded Second Life, told me in an interview a few months ago that latency is a big problem with voice calls over mobile. It leads to "after you" -- "no, you first" awkwardness and has driven the abandonment of voice for various kinds of text messaging. He's obsessed with reducing latency in his new startup, High Fidelity. 

IIRC, he said 150 ms is the thresshold below which people don't notice latency. It feels like the other person is talking to them in the same room.

SO many avenues, opportunities
THis industry likes its labels, so '5G' it is (and ttry stopping the marketing folks from trying to use 5G to sell services come the time...)

What's going to be really interesting is how the development of what 5G is - the specs and standards - will dovetail with IoT, M2M etc

And then there's the spectrum, and security, and....

Let's see what the NGMN comes up with this year.

LTE-U
LTE-U as enhanced 4G makes sense. It will be a stepping stone to 5G, although the speeds could be on par. The 3GPP may want to find a consensus amongst its operator members around LTE-U a bit quicker since the 5G movement is already starting.
