NINA-B1 Wirepas and u-blox have partnered on an advanced decentralized radio communications solution, the NINA-B1 module, for industrial Internet of Things (IoT) applications. The goal of the partnership is to make large scale, decentralized industrial IoT networks easy to deploy for the companies’ customers. The small NINA-B1, which the companies say is comparable to advanced mesh technology, is a stand-alone Bluetooth low energy module with the latest power performance. It can be used for applications such as healthcare, connected buildings, manufacturing and telematics. The module has been certified for a range of countries world-wide, according to the companies. “The NINA-B1, in combination with the Wirepas Connectivity software, enables short time to market for easy-to-install, large scale, decentralized industrial IoT applications in segments such as lighting, sensor, asset tracking and beacons,” says Hakan Svegerud, head of product strategy, short range radio, at u-blox. “We believe that technology should never be the starting point; instead, we should concentrate on business and application needs,” says Wirepas CEO Teppo Hemiä. “As needs evolve over time, so should the technology. Wirepas and u-blox share this core value and that is what makes us stronger together.”
