I do not think that the speed of the Internet connection will be at a fairly good level. For many, this is a really important criterion.
Why do you think so? It does not have to be a hotspot in some large and crowded place. There are many small places where speed will be provided at a fairly acceptable level.
Perhaps you are right, but still it will not be possible to establish the ideal coverage around the world. Not all hotspots have sufficient power to provide excellent coverage and signal
Maybe not, but in large cities with a high population density, this can be one way of getting the Internet. even if you do not talk about big cities, it's still a great solution even for ordinary users, it gives them a certain opportunity, and it's very cool!
