W-Link
Several high-end digital beacons are also equipped with a secondary "supplementary" frequency referred to as W-Link. This frequency broadcasts additional details to other transceivers capable of receiving the W-Link signal. Advertised brand-independent features of W-Link include:
- The ability to resolve multiple, complex burial situations by better differentiating individual transcievers
- More reliable estimation of the number of burials
- More reliable and quicker marking/unmarking of victims (i.e. forcing the transciever to ignore an already found victim)
- More reliable selection of victim search, as the closest victim may not be the easiest to recover
- Ability to transmit and receive additional data including wearer's vital signs or identification
