Unraveling Mesh Networking Options ? Benchmarking Zigbee, Thread and Bluetooth Mesh Protocol Stacks Vortragssprache Englisch

Silicon Labs is in a unique position in the IoT market by offering multiprotocol wireless SoCs, wireless modules, development hardware and comprehensive software tools for each mesh networking protocol: Zigbee, Thread and now Bluetooth mesh. In this session, we will explain why “one size does not fit all” when it comes to mesh networking protocol choices. Each protocol presents unique characteristics and advantages, depending on the use case and end application. Understanding the inner workings of mesh technology goes beyond a list of key features. More importantly, developers need to understand how these network protocols perform in the key areas of power consumption, throughput, latency, scalability, security and Internet Protocol (IP) connectivity. Zigbee, Thread and Bluetooth mesh are all designed differently from the ground up, and one of the key differences that impacts network performance is whether the protocol uses flooding or routing techniques. We have added Bluetooth mesh to our large network test setups developed for Zigbee and Thread evaluation, which enables us to conduct extensive performance testing on all three protocols. Our test network exceeds 500 nodes and is located throughout our test facility in Boston, Massachusetts. This extensive test network allows us to perform advanced testing including firmware updates, command line interface, scripting, timing analysis, packet capture and energy measurements. Leveraging our multiprotocol SoCs and development boards, the same test network can run Zigbee, Thread and Bluetooth mesh, providing a consistent hardware configuration and layout for all three protocol stacks. This unified approach allows us to look at software and network performance in a consistent manner and rule out any hardware or network layout differences. This session will provide developers with detailed results, performance benchmarks and comparisons based on thorough in-network testing. We will then discuss how the three mesh protocols address various use cases and which protocols are better suited for different use cases such as home control, building automation and smart cities.
