Wide-coverage Internet Repeater Enhancement System (WIRES) is a de facto standard created by Yaesu designed to link compatible amateur radio repeaters over Voice over IP, allowing any home stations using those repeaters to communicate with each other over VoIP.

WIRES uses DTMF signaling to make a connection over the Internet from a repeater or home station to another WIRES-equipped station that is accessible over the Internet. No proprietary tones or connection formats are used, so any manufacturer's radio (equipped with a DTMF encoding keypad) may be used to bring up the Internet link.
