- 12Urenloop is an annual 12-hour relay race held at Sint-Pieters square in Ghent, with teams using batons for lap counting.
- Zeus WPI evolved from manual to automatic lap counting, first via Bluetooth modules in batons (2011), then a modernized stack (2019-2022).
- UltraWideBand (UWB) technology enables centimeter-level localization by measuring signal travel time, similar to GPS but on a smaller scale.
- UWB offers advantages like exact position measurement, per-team lap counting, detailed runner statistics, and less noise than Bluetooth.
