Fujitsu Components introduces Wirepas Mesh 2.4GHz wireless modules
Fujitsu Components America has launched the FWM7BLZ22x series of Wirepas Mesh 2.4 GHz embedded wireless modules for flexible mesh network designs.
The series includes three wireless modules, the FWM7BLZ22W, the FWM7BLZ22P and the FWM7BLZ22T.
The FWM7BLZ22W sink interfaces between the router nodes (anchors) and gateway software. It is controlled by a host CPU using Wirepas Dual-MCU API via USB or UART
The FWM7BLZ22P is for positioning applications. The anchor functions as a router node for location detection and can operate in standalone mode or be managed by the host CPU using UART. A USB option will be available in the future
The FWM7BLZ22T tag module is used for positioning applications. A non-router node, the tag indicates the data for the location of moving objects being tracked. It works in standalone mode or can be managed by the host CPU through UART. A USB option will be offered in the future.
All modules in the series are powered by Nordic Semiconductor’s nRF52833 SoC and feature an embedded Mesh 2. GHz stack from Fujitsu’s partner Wirepas, which boasts low power consumption from a voltage range of 1.7V to 3.6V. The Wirepas Mesh 2.4GHz architecture can accommodate changes to data transmission routes locally in the network environment, such as device failures and increases or decreases in the number of devices. The architecture also allows for easy deployment of small or large-scale decentralised systems and supports wireless remote firmware upgradeability (OTAP or over the air programming).
With dimensions of 7.5 x 7.9 x 1.7mm, the small footprint requires a minimal mounting area on the PCB. An enhanced output power of +8dBm enables potential transmission range extension, while strong resistance to radio interference – a feature of Wirepas Mesh 2.4GHz – allows higher-density installation to seamlessly work with existing nodes. There are no embedded antennas, maximising the flexibility of electrical and housing designs.
The modules can be used with existing Fujitsu mesh network products. Key applications include asset management, sensor networks, and smart lighting.
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, and input and pointing devices.
