Tracker employs Nordic’s nRF52833 SoC enabling wireless proximity detection and contact tracing
Designed to prevent virus transmission at the source, the personnel tracking solutions are claimed to help companies keep employees safe during the Covid-19 pandemic by enabling social-distancing and contact-tracing applications based on proximity-detection and location-tracking technology.
The BT710 is a long-range, flexible device platform featuring LED, vibration, and audible social distancing alerts to help workers practice safe social distancing and support contact tracing when used in conjunction with gateways to log proximity data. The platform’s integrated TruePoint Diversity Antenna System (TDAS) enables improved location accuracy by providing an omnidirectional antenna pattern to eliminate many of the “false alarms” typically used in single antenna Received Signal Strength Indication (RSSI) systems. For even greater accuracy (better than <1 meter), the BT720 uses its full real-time location services (RTLS) tag functionality supported by Quuppa’s proprietary direction finding technology. In both the BT710 and BT720, a built-in accelerometer is used to trigger a reduction in power consumption when the trackers are not in motion, while a barometer is included to provide better resolution in tracking the location and elevation of people and assets.
Bluetooth 5.2 support
The nRF52833 SoC combines a 64MHz, 32-bit Arm Cortex M4 processor with floating point unit (FPU), with a 2.4GHz multiprotocol radio (supporting Bluetooth 5.2, Bluetooth mesh, Direction Finding, 2Mbps throughput, and Long Range plus Thread, Zigbee, IEEE 802.15.4, and proprietary 2.4GHz RF protocol software). What Nordic says is a ‘generous amount of memory’ (512kB Flash and 128kB RAM) and dynamic multiprotocol support enable concurrent wireless protocol connectivity. Nordic believes that this ensures the nRF52833 is a suitable device for running complex contact tracing applications.
