A Wi-Fi hotspot is really just a wireless access point.
Typically, they are public locations where you can access the internet through Wi-Fi on your mobile devices. They are convenient, but there are also some security issues to be aware of when using them.
Technically, there’s nothing distinguishing a Wi-Fi hotspot from any other wireless access point. You could consider the wireless router in your home to be a Wi-Fi hotspot. However, when we talk about hotspots, we’re usually talking about the public, physical locations where you can sign on to Wi-Fi (often for free).
