“Tethering means sharing the Internet connection of an Internet-capable mobile phone or internet tablet with other devices. This sharing can be offered over a wireless LAN (Wi-Fi), over Bluetooth, or by physical connection using a cable. In the case of tethering over wireless LAN, the feature may be branded as a mobile hotspot. The Internet-connected mobile phone acts as a portable router when providing tethering services to others.”
* “A hotspot is a site that offers Internet access over a wireless local area network through the use of a router connected to a link to an Internet service provider. Hotspots typically use Wi-Fi technology.”
