There’s a lot of hype about 5G just as there was with 4G and 3G before that but yes once fully established it will be better than the previous generations but I likened it to my home broadband where I was happy with 25Mb down load then they increased it to 50 Mb download but now have 100 Mb down and 250 Mb down if I wanted but Netflix HD , Now TV HD, surfing the WEB etc. worked perfectly well at 25 as it does at 100 and all that changes is the cost which of course is in an upwardly manner.
5G will be no more capable of making a cup of tea that 4G does now but if it could then you might get your tea 5 thousandths of a second faster. ?
