The traditional approach to reliability was to use acknowledged messages, have the sender wait for the acknowledgment to come back, and, if it did not, send the original message once again.
The reliability and scalability are what enable broad market adoption of wireless technologies for sensing and lighting control.Ĭan you explain the proactive retransmission technique that Bluetooth mesh utilizes and how it contributes to the reliability of a Bluetooth mesh network? They are the key, fundamental reasons behind the reliability and scalability of Bluetooth mesh networks. How does Bluetooth technology overcome potential interferers and enable reliable wireless data communication?Ĭompact, fast, radio-efficient data packets make the foundation for Bluetooth ® mesh. The global industry uptake of Bluetooth mesh, we have seen since its adoption in 2017, has proven this approach has been right. We believe the properties of Bluetooth mesh make it a perfect contender to change that by enabling highly scalable, highly reliable, and dependable low-power wireless mesh networks for buildings. Despite a seemingly broad choice of technologies, wireless mesh networks never managed to capture the commercial and industrial markets because they never offered sufficient reliability and scalability. We have been one of the top contributors to the Bluetooth mesh standard, always prioritizing reliability as the key enabler for the products and markets. It has also turned out to be the fastest-growing technology, with the organization and the community open for new developments – and this is how Bluetooth mesh was born. Bluetooth LE has, by far, been the best radio available. It was obvious to us that many things about wireless systems could be fixed or improved, but the most important was the foundational radio technology. We had experience with multiple low-power wireless technologies and decided to bet on Bluetooth ® LE even before Bluetooth mesh was developed. What does the reliability of Bluetooth technology enable for your company?
We realized it was much more feasible to design a new mesh networking standard based on the solid foundation of Bluetooth LE rather than trying to improve the standards based on other radio technologies. It became clear to us for any highly scalable and reliable system that we needed to start with the highest efficiency radio technology, enabling ultra-short packets and multiple frequency channels. It was impossible to achieve the reliability and performance required by commercial lighting use cases with other 802.15.4 technologies. We tested Bluetooth ® Low Energy (LE) with several variants of 802.15.4 technologies (IP-based and non-IP-based on both sub-GHz and 2.4GHz frequency bands) back in 2012-2013.
