Or - alternatively - you can even legally purchase it for a mere US$ 33 (US$ 14.95 if you are member) from IEEE.org

Its safe to assume that 5G will run mostly on 28GHz due to oxygen absorption, see here

Latest SK Telecom tests of 5G are on 28GHz with Wireless 5G Relays (they prepare for winter olympic games Feb '18 -)

RoE Radio over Eth comes with 5G alongside the 28GHz spectrum. Some slides to fly-over, relax

A swiss operator offers the option ´multi device´ which is multiple SIM cards (max. 3) concurrent usage but same contract. See here

https://www.swisscom.ch/en/residential/mobile/options/multi-device.html

How runs the proper authentication related to the geolookup fraud prevention? As offered for families their members can be split around the globe in different time zones.

Where do they limit the offered partial contract services (lets limit on data incl. VoLTE)?

Crack the nut yourself or PM me. Lets Block Criminals! on FF.

5G System Phase 1 NR standards were released Dec 21th 2017. Network slicing (optional by operator) will bring adaptive beamforming and beam tracking (like tracking requests in LTE for automatic handovers to the neighbour cells). These 3 standards are final - ready to learn

TS 23.501 SA for 5G Systems Phase 2
TS 23.502 Procedure for 5G Systems Phase 2
TS 23.503 PCF for 5G Systems Phase 2

5G System 5G UE, 5G Access Network AN, 5G Core Network CN

http//www.3gpp.org/news-events/3gpp-news/1930-sys_architecture

Slicing you can compare like tagging packet data traffic in VLANs.

The beam formed by a module out of array antennas follows the user like a spotlight follows an actor on a stage. This is more power-efficient and reduces latency to 3ms in tests, the goal is 1ms for UAVs.
