As somebody not very well-versed in this, a sincere question. Would something like 5g be able to replace a home intranet / network? Eg I have a personal media server that I stream to devices on my wifi--would this be able to work with 5g? From my perspective 5g can only replace internet access, yes? Devices that want to communicate with each other securely would still prefer to be connected over wifi or other personal network like Ethernet?
