Embedded Wirepas Massive Network Units for Large-Scale Network Installations in Real-Time Locating Systems and IoT Applications

 Wirepas Massive Network Units

Fujitsu Components has introduced a line of the embedded FWM7BLZ20W mesh network and multi-sensor units with built-in Wirepas Massive network connectivity for real-time locating systems and smart industrial IoT applications. These nodes facilitate dense, large-scale network installations for industrial monitoring of IoT applications in offices, factories, warehouses, hospitals, schools, and more.


The embedded FWM7BLZ20W Fujitsu Wirepas wireless modules are based on Nordic nRF52832 and measure 74.2 x 74.2 x 28.0mm. The units comprise of detachable brackets for easy installation and maintenance. The operating temperature ranges are -20 to +60 deg C (CO2 sensor version starting from -10deg Celcius) and they are FCC/ISED, CE, and Radio Act Japan certified.


The family of Wirepas wireless modules comprises of several units viz. FWM8BLZ08A Mesh Anchor unit for location/asset tracking reference point, FWM8BLZ08T Mesh Tag unit with an acceleration sensor for location/asset tracking,  FWM8BLZ08Y Mesh sensor unit with embedded temperature, humidity, barometric pressure, illuminance, sound level, and acceleration sensors, FWM8BLZ08C Mesh CO2 sensor unit also includes onboard temperature, humidity, barometric pressure, illuminance, sound level, and acceleration sensors.


While carbon dioxide sensor units in the family are powered by USB-C, the other units in the family can be powered by 4 AA batteries or USB-C. Each device in the family is IP-65 rated against water and dust. This makes them suitable for use in wet or humid/damp indoor environments. Using these Fujitsu Mesh Anchors, Mesh Tags, and Mesh Sensors, the Wirepas Positioning Engine provides excellent location awareness of stationery items and moving assets, making them ideal for a multitude of IoT applications.
