You need to connect your laptop to the internet, but there are no available Wi-Fi or wired networks. You can, however, use your cellphone's cellular data to create a personal wireless network for your laptop. What is this functionality called?
NFC
Hotspot
USB
Bluetooth
Many smartphones can function as a mobile hotspot. This feature allows the phone to share its cellular data connection by creating a localized Wi-Fi network that other devices, such as laptops, can connect to for internet access. While USB and Bluetooth can also be used to share an internet connection (a process called tethering), creating a wireless network for other devices to join is the primary function of a mobile hotspot.
