InJuniper Networks Mist AI Wireless Real-Time Location System (RTLS)design discussions, multiple location technologies are commonly compared based on accuracy, reliability, and use-case suitability. Among the listed options,Ultra Wide-Band (UWB)provides thegreatest location accuracy.
UWB achieves superior accuracy because it usesvery short-duration radio pulses across a wide frequency spectrum, enabling extremely precisetime-of-flight (ToF)andtime-difference-of-arrival (TDoA)measurements. This allows UWB systems to determine device location withdecimeter-level precision, often in the range of10–30 centimeters, even in complex indoor environments. UWB is also highly resistant to multipath interference, which is a major limitation of Wi-Fi and BLE-based positioning systems.
By comparison:
Wi-Fi–based locationrelies on RSSI and sometimes Angle of Arrival (AoA), typically achieving3–5 meter accuracyunder good conditions.
BLE badgesimprove accuracy over Wi-Fi by using beacon proximity and BLE signal characteristics, often achieving1–3 meter accuracy, depending on beacon density and calibration.
SDK-enabled mobile applicationscan enhance BLE or Wi-Fi accuracy by leveraging motion sensors and device context, but they are still constrained by the underlying RF technology and rarely reach sub-meter precision.
While Juniper Mist’s vBLE and AI-driven probability surfaces deliver industry-leading accuracy for Wi-Fi and BLE-based RTLS use cases such as wayfinding, asset visibility, and proximity engagement,UWB remains the most accurate indoor positioning technology overall. Its precision makes it ideal for high-value use cases such as medical equipment tracking, industrial automation, and secure access control.
Therefore, the correct answer isUltra wide-band (UWB), as it provides thehighest level of location accuracyamong the listed solutions.
