Fujitsu releases Wirepas Mesh IoT front-end devices for secure, scalable and flexible IoT applications
Fujitsu Component Asia released a series of battery-powered Wirepas Mesh technology mesh units and mesh-sensor units. The devices simplify construction of large-scale decentralized networks to allow scalable, reliable and cost-effective IoT solutions for position tracking and sensor data collection.
In addition to deploying large-scale networks, the mesh units (FWM8BLZ07P) and mesh-sensor units (FWM8BLZ07Y) enable power saving, high-density networks with interference tolerance channel selection, transmitting power control and autonomous network rerouting capability. If the network environment changes, adds and/or removes the end device, or if a device failure occurs, the mesh topology and protocols will automatically reconfigure the mesh network. Furthermore, a security key ensures a secure communication environment throughout the network.
The FWM8BLZ07P mesh unit is well-suited for wide-area asset tracking. It features a long-sleep mode and an integrated sensor that wakes up only if certain events, like shock, are detected. This function further conserves energy because communication begins only when needed.
The multi-function FWM8BLZ07Y mesh-sensor unit incorporates a unique combination of temperature, humidity, air pressure, illuminance, 3-axis acceleration, and sound-level sensors. This makes it adaptable for a variety of massive, sensor data collection systems with scalable mesh topology. Since the sensor data paths through the mesh network topology, the end-node’s placement is not limited by the gateway's location.
Both mesh units are based on the Nordic Semiconductor nRF52832 SoC and measure a compact, 40.0 x 31.0 x 12.0 mm within a gray, plain housing, adaptable for many applications. They use a single CR2450 coin-cell battery and include a voltage notification function, which senses a voltage drop in the battery and allows users to determine the right timing for replacement.
