Two events that are displayed under Client Events area found on Insights page are Reassociation and DHCP Denied. So the correct answers are A. Reassociation and D. DHCP Denied.

In Juniper 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 the greatest location accuracy.

UWB achieves superior accuracy because it uses very short-duration radio pulses across a wide frequency spectrum, enabling extremely precise time-of-flight (ToF) and time-difference-of-arrival (TDoA) measurements. This allows UWB systems to determine device location with decimeter-level precision, often in the range of 10–30 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 location relies on RSSI and sometimes Angle of Arrival (AoA), typically achieving 3–5 meter accuracy under good conditions.

BLE badges improve accuracy over Wi-Fi by using beacon proximity and BLE signal characteristics, often achieving 1–3 meter accuracy, depending on beacon density and calibration.

SDK-enabled mobile applications can 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 is Ultra wide-band (UWB), as it provides the highest level of location accuracy among the listed solutions.

Transmissions over Wi-Fi are shared medium and half-duplex.

According to the IEEE 802.11 - Wikipedia document2, two terms that correctly describe transmissions over Wi-Fi are:

Shared medium, which means that multiple devices use the same wireless channel and have to compete for access and avoid collisions.

Half-duplex, which means that devices can either transmit or receive data at a time, but not both simultaneously.
