[ Computer Networking ] Open Question : How will Wifi Connection be
accessible to a large number of students?

I just want to ask, what is the best solution if for example you want to
have your University a wifi connection where students can connect and use
it for their study but you want to make it accessible for a large number
of students without sacrificing the speed of the internet. Is that part of
a hardware, software or network problem? Thank you guys, Im sorry Im just
curious advance thank you for those who will answer this sincerely
