USPACE-KYD-2F Functionality 2 Functionality 2.1 General Purpose – Distance Monitoring The Uspace-KYD is a professional distance alerting tag, especially designed to detect risky situations, such as human-to-human minimal distance transgression for Covid-19 sanitary protection, or dangerous objects proximity. In active (monitoring) mode, the tag scans for the presence of other tags using the DASH7 sub-GHz protocol (ISM 915 MHz) and makes distance measurements to each of the detected tags using UWB.
PAGE 5
USPACE-KYD-2F Functionality 2.2 Monitoring zones and events Tags are out of the “view zone” if they are not mutually accessible over the DASH7 scan wireless link or when their relative distance, measured in terms of signal attenuation (link budget) exceeds a certain threshold (typically 80 dB). The view zone’s radius is thus typically roughly 10-20m. When a tag is in the view zone of a distant tag, it first gets the distant tag custom “alert zone” and “safety margin”.
PAGE 6
USPACE-KYD-2F Functionality When the tag enters the view zone of the distant tag, both generate a “Start Contact” event. The contact continues but alert is not triggers out of the alert zone (in particular it is not triggered in the safety margin zone). When the tag enters the distant tag’s alert zone, both tags generate a “Start Alert” event and the alarm notification, composed of a LED blinking, buzzer and vibrator patterns, is played.

USPACE-KYD-2F Functionality 2.3 Contact Events Management The tag has different contact events recording/reporting management modes : * Stand-Alone : Events are not recorded * Stand-Alone with traceback : Events are recording in internal flash and can be dumped through serial or BLE. * Real-time monitoring : Events are recorded in internal flash and reported over-the-air immediately to a Cloud service All gathered contact information is anonymous.

USPACE-KYD-2F How to use 3 How to use 3.1 Just charge-and-play The tag is fully pre-configured and not requiring any initial setup through web or mobile application. The tag is fully autonomous, its alerting functionality does not depend on the availability of any local or global network connection. In particular, even in real-time monitoring mode, the absence of DASH7 connectivity does not alter the alerting functionality. Reports history, when enabled, remains accessible in the tag’s flash memory. 3.

USPACE-KYD-2F How to use 3.3 Charging When the tag is connected to an electronic device’s USB port or 5V DC power supply with USB connector, the tag enters charging mode, and the LED starts blinking in orange. The tag becomes inactive (no scanning). It remains accessible for configuration updates (see Advanced Configuration Section 4). When the battery is fully charged, the LED will start blinking in green.
PAGE 10
USPACE-KYD-2F How to use 3.4 Low Battery When the battery is low, the LED makes a single orange blink on every battery measurement (default every minute). The device continues functioning in the current mode. If critical low battery level is detected, the device degrades to deepsleep mode and can only be reenabled by charging the battery above the critical low level. If the battery level drops below the microcontroller’s brown-out reset (BOR) level, the device shuts down.
PAGE 11
USPACE-KYD-2F How to use Depending on the Contact Management option, described in 2.3, contact events and reported overthe-air to the cloud. The alerting pattern stops when a End Alert event is detected or after a alerting timeout.
PAGE 12
USPACE-KYD-2F How to use 3.7 Tap-to-connect A device, supporting the tap-to-connect protocol, can establish BLE connection with the tag. The procedure is initiated by an NFC access event that triggers the immediate exit from monitoring mode and disabling of all DASH7 (sub-GHz) and UWB interfaces. The tag start blinking in blue. The tap-to connect is meant to be used as an alternative for configuration and report dumping.

USPACE-KYD-2F Advanced Configuration 4 Advanced Configuration This section describes the Advanced Configuration Interface, accessible only to the system administrator over the dash7board WizziLab’s Cloud Service. The configuration of USPACE can be done using 2 files: • APP_CONFIG file allows to configure the behavior of the TAG itself • APP SHARED CONFIG is exchanged with neighboring TAGs during the discovery process. It allows the other TAGs to know how to behave in presence of this TAG. 4.
PAGE 14
USPACE-KYD-2F Advanced Configuration the presence of Gateways, it is better to keep the TAG plugged all the time while remaining active. • Passive: When checked this option prevents the TAG to actively discover the neighboring TAGs.
PAGE 15
USPACE-KYD-2F Advanced Configuration 4.2 APP_SHARED_CONFIG PARAM1 Is distance: When checked, the metric used to “range” is a distance. When unchecked use Link Budget Hysteresis: in dm for distances, dB for Link Budget. A Triggered alarm is released when distance greater the Distance+Hysteresis Distance: in dm for distances, dB for link budget. Distance at which the alarm is triggered. PARAM2 Alarm Pattern: Pattern to use on devices in alarm conditions with this device.
