Re: Of course it's nearly all bollocks
ITU has a nice triangular diagram that shows three main use cases for 5G: faster Internet, IoT, and applications (remote surgery is often cited) where latency matters. The first of these is LTE with a few tweaks, and is the only one being delivered, or even really supported by the 3GPP standards, as of now.
The main problem for IoT is battery life in devices that are so cheap you can have lots of them in different places; IPv6 over LTE is the problem there, not the solution, because of the amount of data to be transmitted to upload a couple of bytes-worth of information.
Critical applications that need low latency need something more than just a bit less contention for a best-effort service, and no, slicing is not a viable way of achieving it.
