# Digipeater

AI-generated

A digital repeater:
a station that retransmits [AX.25](../ax25/index.html.md) frames
whose path names it, or a generic alias such as `WIDE2-2`,
marking that hop as used so the frame doesn’t bounce back and forth.
[APRS](../aprs/index.html.md) relies on them to extend a station’s reach,
and the `WIDEn-N` scheme limits how far a packet spreads.
