Wirepas Mesh is scalable for decentralised networks

Battery-powered Wirepas Mesh technology mesh units and mesh sensor units from  Fujitsu Component America, simplify the construction of large-scale decentralised networks, says the company. They allow scalable, reliable and cost-effective IoT for position tracking and sensor data collection.

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, says Fujitsu. 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. 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 temperature, humidity, air pressure, illuminance, three-axis acceleration and sound-level sensors. It can be adapted for a variety of massive, sensor data collection systems with scalable mesh topology. Sensor data paths through the mesh network topology mean that the end-node’s placement is not limited by the gateway’s location, says Fujitsu.

Both mesh units are based on the Nordic Semiconductor nRF52832 SoC and are compact. They measure 40.0 x 31.0 x 12.0mm (1.57 x 1.22 x 0.47 inches) within a grey, plain housing. 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.

The mesh and mesh sensor units and position tracking support software are available now.

Fujitsu Components America markets and distributes electronic and system components and sub-systems throughout North and South America. Products include relays, touch panels, thermal printers, wireless modules, connectors, and input and pointing devices.

The company is headquartered in Sunnyvale, California, USA.
