The Pope is a Catholic
Major supplier of 5G infrastructure touts 5G as a solution for everything needing data.
It's for mobile in stadiums, racetracks and a subscription alternative to public free WiFi hotspots. The lower bands are better for true mobile and fibre is over 1000 times per Mbit less environmental cost than mobile (cell) masts. Anything fixed should use fibre and in a premises wired ethernet as much as possible leaving free wifi fed by real broaband for phones, tablets and gadgets.
Wireless, no matter which "G" can only replace broadband if every other street lamp is fibre fed and a 5G or 4G cell.
