VPN is just an extra layer of network software

VPN is just an extra layer of network software on top of your physical network layer. It is totally independent of your connection, therefore it will work with WiFi, 2G/3G/4G cellular network, Ethernet or an analog modem over your old telephone line.

It will let you tunnel your internet packets to another location so other people can't find out your true IP address, or you can tunnel securely into a private network as well (like right behind a enterprise firewall).
