u-blox AG: Bluetooth 5.1 module enables mesh networking for 'massive IoT' applications - Seite 2

Wirepas Massive can be deployed in smart tracking, smart logistics, smart building, smart industry, and smart metering applications, or whenever there is a need for large-scale industrial-grade network deployments. Wirepas Massive introduces 2 times higher throughput, reduced power consumption, a dynamic provisioning algorithm that automatically authorizes new nodes in an existing network and enables roaming for logistics use cases, open source gateway software, a simpler protocol node-node system that doesn't require any back-end link, high-density ultra-fast inventory (thousands of devices in less than one minute, for example in warehouses), directed advertising mode for reliable ultra-low power light switches, and advertising space extended to 32-bit to support ultra-large networks.

The NINA-B4 module also supports Bluetooth 5.1-including direction finding-and can operate at an extended temperature range up to 105 C - which, together with its long range capability, makes it ideal for deployment in harsh environments. Designed to act as both a transmitter and receiver (using angle-of-arrival (AoA) and angle-of-departure (AoD) direction finding), the NINA-B4 modules bring the benefits of high-precision positioning to indoor applications. The integrated nRF52833 SoC's multiprotocol radio is capable of all direction finding features for AoA and AoD applications. The SoC's generous memory allocation enables integration of advanced embedded customer applications.

Nordic's nRF52833 multiprotocol SoC supports the large-scale, low power Wirepas Massive mesh connectivity software enabling cost-effective, scalable IoT solutions with density, flexibility, and reliability. For example, a network of anchor nodes and up to hundreds of thousands of end-devices could be placed throughout a location and wirelessly linked using the Wirepas Massive connectivity integrated in the Nordic SoCs. Collected sensor data and analytics could then be relayed via Wirepas Massive to a u-blox NINA-B4 module-equipped gateway, which in turn sends the data to the cloud.
