1 iiot requirements for wireless connection
There are three general types of wireless networks in industrial Internet of things (iiot) applications: (1) proprietary networks developed, implemented and maintained by customers; (2) Standards based wireless networks deployed and maintained by customers; (3) An existing cellular Internet of things (IOT) network that customers access in the form of payment, such as lte-m or Nb IOT. Cellular IOT network is an ideal choice for industrial IOT applications, such as asset tracking across long distances and large regions (such as cities, states / provinces and even nationwide).
When choosing a communication network for industrial Internet of things applications, customers must consider various technical and cost factors. For many customers, these considerations will continue to drive them to build and maintain their own networks using proprietary or standards based wireless networks. We predict that these networks will coexist with cellular technology in the foreseeable future. Although 5g has broad application prospects in the industrial Internet of things, the existing wireless technologies can provide scalable and cost-effective connections for machine to machine (M2M) and machine to cloud applications that only need low data rate.

2. What kind of wireless communication standards are you optimistic about
Silicon Labs’ wireless Internet of things solutions widely support a variety of wireless protocols, including ZigBee, thread, Bluetooth mesh, low-power Bluetooth, Wi Fi, Z-Wave and proprietary protocols. We provide rich device combinations for IOT applications, including Wireless SoC and modules, microcontrollers and sensors, so that customers can build a complete system to monitor environmental changes, process data locally, and transmit data to the cloud for analysis using wireless technology. Our customers and partners can also use our RF products to realize more wireless communication protocols such as wireless M-BUS, wi sun, isa-100 and WirelessHART to meet the needs of specific industrial applications.
As one of the key differentiation elements of silicon labs, we provide an impartial wireless connection for the industrial Internet of things. Silicon labs provides customers with unprecedented flexibility to choose from a variety of optional wireless protocols because our wireless devices are built on a common and scalable platform that supports a variety of standards and proprietary protocols. For the industrial Internet of things, silicon labs provides flexible connectivity technology options, including a variety of leading, standards based protocols that can run at 2.4 GHz and most proprietary protocols that operate below 1 GHz. All these functions can be integrated on the same wireless system on chip (SOC) device.
The wireless devices of silicon labs also support multi protocol operation, allowing connector devices to dynamically switch between different protocols at runtime, thus providing a huge space for application developers to design devices with excellent interoperability and connectivity. Support multi protocol connection in the same wireless device, so that customers can connect to different heterogeneous networks, or upgrade their networks on the spot with the continuous development and evolution of wireless standards. We have developed a platform approach for wireless hardware and software, and also enable customers to take full advantage of their investments in diverse communication networks. This function supports customers to deploy products to today’s fragmented industrial Internet of things market, and maximize connectivity while the ecosystem continues to evolve and develop.
The industrial Internet of things involves a large number of different applications and markets. Silicon labs focuses on building automation, intelligent lighting, intelligent meters, asset management and other similar industrial Internet of things applications, which require standard based and proprietary low-power wireless connections. In order to meet these application requirements, silicon labs provides various Wireless SoC and module devices with different hardware integration and connection technologies to enhance the integration of the whole system and help developers reduce system cost and complexity.
3 silicon labs solutions
3.1 wireless gecko Series 2 platform (Wireless SoC chips and modules): silicon Labs’ next-generation Series 2 wireless gecko product portfolio is designed to make Internet of things products more powerful, efficient and reliable. Based on the proven RF and multi protocol capabilities of wireless gecko product portfolio, series 2 provides a general and scalable Internet of things connection platform and Miniaturized Wireless SoC. These chips have special security protection core and on-chip RF; They provide 2.5x wireless coverage compared to competitive solutions. With the continuous adoption and growing diversity of IOT devices, developers are looking for flexible connectivity solutions to help them quickly bring differentiated products to market while reducing cost and design complexity. Series 2 meets this need and improves several design elements, including wireless performance, reliability, software reuse and enhanced security, to accelerate the development, deployment and adoption of the Internet of things. The first series 2 products include efr32mg21 SOC chip supporting multiple protocols such as ZigBee, thread and Bluetooth mesh network, and efr32bg21 SOC chip dedicated to low-power Bluetooth and Bluetooth mesh. These SOCS provide ideal solutions for IOT products powered by gateways, hubs, lighting, voice assistants and smart meter wires.
Silicon labs recently launched a new portfolio of highly integrated and secure Series 2 modules that reduce development costs and complexity, making it easier to add powerful mesh network connections to a wide range of Internet of things products. The new mgm210x and bgm210x Series 2 modules support leading mesh network protocols (ZigBee, thread and Bluetooth mesh), low-power Bluetooth and multi protocol connections. The initial series of the series 2 module portfolio includes the industry’s first pre certified wireless module optimized for LED bulbs, and a general printed circuit board (PCB) shape module designed to meet the needs of various ultra-small Internet of things products.
In order to help IOT developers protect their products from malicious attacks, silicon labs includes first-class security features when designing series 2 SOC and modules. For example, secure boot using trusted root and secure loader (RTSL) technology helps prevent malware injection and rollback, ensuring reliable and secure firmware execution and wireless (OTA) updates. The special security kernel isolates the application processor and provides fast and efficient encryption operation through differential computational energy analysis (DPA) countermeasures. The NIST sp800-90 and ais-31 compliant true random number generator (TRNG) enhances device encryption. The security debugging interface with lock / unlock function supports authenticated access to enhance fault analysis. The arm cortex-m33 kernel of this module integrates TrustZone technology, which can realize system level hardware isolation for trusted software architecture.
3.2 wireless gecko Series 1 Platform (Wireless SoC and module): silicon labs launched the first generation of wireless gecko in early 2016. Since then, the SOC, modules and software of wireless gecko Series 1 platform have become the industry-leading multi protocol and multi band Internet of things connectivity solution, providing flexible wireless protocols and cost-effective options for various Internet of things applications and markets. The platform integrates a powerful arm cortex-m4 core, energy-saving gecko technology, 2.4 GHz RF with up to 19.5 DBM output power and advanced hardware encryption technology. In order to accelerate wireless application design, wireless gecko SOC adopts the best thread and ZigBee protocol stack in the industry for mesh networks, intuitive RF interface software for proprietary protocols, low-power Bluetooth for point-to-point connection, and simplicity studio tools that can simplify wireless application development, configuration, debugging and low-power design.
