Most indoor-tracking platforms lean on received-signal strength (RSSI) to infer distance. That’s fine when you only need “room-level” awareness, but signal strength fluctuates every time a pallet is moved, a conference room fills, or humidity shifts. The result is a tug-of-war between constant re-fingerprinting and middling precision that rarely beats 1–5 m. Technologies such as Wi-Fi, Bluetooth LE and active RFID all inherit these RSSI limitations, so accuracy tends to wander and maintenance overhead creeps upward as a site grows.
TagTrack breaks that pattern by timing the flight of ultra-wideband (UWB) pulses from its DW3000-equipped tags to ceiling-mounted anchors. Each 500 MHz-wide burst is stamped to a fraction of a nanosecond, converting directly into centimetre-grade ranges that remain stable even in dense multipath or high-traffic areas. Because distance is derived from time—rather than signal strength—our system ignores moment-to-moment variations in the radio environment and needs no periodic recalibration. The result is an RTLS that installs quickly, scales from a single lab to an entire factory floor, and keeps delivering mission-critical accuracy without the upkeep.
| Technology | Sends ID & Data | Accuracy | Consumed Power | Range (m) | Cons |

| AI Vison | scenario dependat | VERY HIGH | 10 | Requires line of sight and a lot of computing power. | |
| QR Code | scenario dependat | VERY HIGH | 5 | Requires line of sight & provides a relative position. | |
| Laser | 1mm-3mm | VERY HIGH | 5 | Requires line of sight & provides a relative position. | |
| Infrared | 50cm-100cm | VERY HIGH | 5 | Requires line of sight & provides a relative position. | |
| Ultra Sound | 10cm-20cm | VERY HIGH | 5 | Requires line of sight & provides a relative position. |
Every indoor-tracking option in the comparison table carries its own trade-offs—range, power draw, cost, or line-of-sight constraints—so the right choice always comes down to what your application values most. TagTrack is built on Ultra-Wideband because, despite a few environment-specific limits (for example, large metal obstacles can attenuate the signal), UWB consistently delivers the sub-meter precision and interference immunity that high-stakes workflows demand.
In short, impulse-based UWB gives TagTrack the accuracy of lidar, the penetration of RF and none of the spectrum headaches—perfect for reliable, secure indoor positioning at scale.
