How can I connect up to 100 users to a router or router?

Question

network hardware

The task is this: We want to install a router (or several routers) in the park so that up to 100 users can connect to it. After that, there is a limited distribution only to a specific site where the video will be broadcast with a resolution of, for example, 640x360 in real time, i.e. the video cannot be rewound or paused.
Please tell me with which router or router it is possible to do this or without the Internet it is possible with the help of streaming video through some kind of server.
Thanks in advance!!!!!
