A real-time location system (RTLS) continuously calculates the position of tagged people, vehicles or assets inside a building, using fixed anchors and a radio such as ultra-wideband or Bluetooth Low Energy.
An RTLS places anchors on walls or ceilings, attaches tags to forklifts and sometimes to workers, and computes each tag’s position from the radio signals. In forklift safety it supports zone rules (slow down in this aisle, keep out of that area), heat maps of where trucks and people meet, mustering headcounts and fleet utilization. The site’s RTLS overview covers anchor layout, tag types and update rates.
An RTLS is infrastructure, not a collision warning in itself. Truck-to-person warnings usually come from direct tag-to-tag ranging on the vehicle, which keeps working where anchor coverage is thin. Position accuracy depends on the radio, anchor density and the building, so a dense rack area can perform worse than open floor. Update rate matters too: a tag that reports slowly is fine for asset tracking but too slow for live safety rules. Location data about named workers also raises privacy questions that should be settled before rollout.
