3. When referring to a wireless network, a Wi-Fi hotspot or wireless hotspot is a location that enables users to connect to a network or the Internet with their wireless adapters.
Most smartphones today can be configured to create a Wi-Fi hotspot, allowing computers and tablets to connect to the Internet using the Wi-Fi signal generated by the smartphone.
Some mobile phone carriers also offer a device called a Mobile Hotspot, which allow users to connect non-phone devices to the data network of the mobile phone carrier. Carriers such as Sprint, AT&T, and Verizon offer a mobile hotspot for an additional monthly fee, typically starting around $29 a month.
The mobile hotspot connects to the carrier's data network, typically either a 3G or 4G network. This turns the signal into a Wi-Fi signal that another device, like a computer or tablet, can connect to and use to surf the Internet. The mobile hotspot can run on a battery or can be plugged in to a power outlet.
