I know this isn't as such a helpdesk problem but I was wondering if someone could clarify how WiFi works?
I’m slightly confused as to how WiFi would give people internet access from anywhere at anytime as is promised by so many retailers.
For example I have heard that restaurants, airports etc will soon be implementing “WiFi hotspots” for users to connect to the internet. How does this work in terms of connecting to an ISP?
Surely a broadband connection is required close by to connect to (WiFi must have its distance restrictions). Basically (because I’m confusing myself right now!!) what is required for a user with a WiFi enabled laptop to connect to an ISP?
Hope someone can help clear this up for me
