The Telecommunications Industry Association (TIA) has surveyed the 5G views of 31 mobile network operator executives from around the world. The findings were recently published (registration required). It’s implied that the survey used 5G in the most common sense — that of 3GPP, which has targeted completion of 5G specifications for 2020. (No one owns the term 5G — Verizon has its own 5G specifications, at least for now.)
Use cases that are expected to be most transformed by 5G are those involving higher data rates (naturally) and low latency (such as automotive communications).
