Anchor Density

The number of anchors deployed per unit area, typically per 100 square meters. Higher density improves accuracy, provides redundancy, and reduces coverage gaps. Optimal density balances performance requirements against infrastructure costs, typically ranging from one anchor per 100-400 square meters.

Number of RTLS infrastructure devices per unit area, critical parameter affecting system accuracy, reliability, and cost. Industrial installations typically deploy 1 anchor per 400-1000 m² for UWB systems targeting 30 cm accuracy, or 1 per 1000-2000 m² for BLE/Wi-Fi systems with meter-level requirements. Higher density provides benefits: improved accuracy through better geometric dilution of precision (GDOP), increased redundancy if anchors fail, reduced impact of obstacles through multiple signal paths, and support for higher tag update rates. However, density beyond optimal points provides diminishing returns while increasing installation and maintenance costs. Critical principle: anchor placement geometry matters more than absolute density - ensure good spatial distribution and avoid colinear anchor arrangements that degrade positioning accuracy.
