(Electronic Enthusiast Network Report / Zhang Ying) Recently, at the International AIoT Conference, Mr. Zhou Wei, General Manager of Silicon Labs China, explained the latest trends in intelligent wireless connection technology solutions.

First, IoT businesses face three major challenges. The first is security, which is the most important, and there are many challenges to consider; the second is the transmission range, how to extend the communication protocol from indoor to outdoor, and the effective transmission distance of more than 1 km; An ecosystem of utility; and finally an integrated solution.

He emphasized that the security of hardware and protocols is critical to an unconnected future. And devices that support remote protocols help enable more innovative applications inside and outside the home.For example, it was widely believed that Bluetooth technology was only suitable for short-range applications. This was largely due to the early initial use cases of the technology. Since use cases such as audio transmission and wearable devices only needed to meet the design requirements of short distances, the development of The maximum distance that users choose these technologies and hardware to achieve is 10-30 meters, but the latest Bluetooth 5.2 technology is used for positioning, the effective and reliable distance between Bluetooth devices can exceed one kilometer, and it can even help achieve no Stable remote control of man-machine.

Zhou Wei analyzed: “Ecosystems and technology alliances such as Zigbee, WiFi, Bluetooth, OPEN Thread, and Amazon are driving the growth and innovation of the IoT market.” He particularly introduced: “Silicon Labs has provided a wealth of Matter wireless solutions. source code, accounting for 22%. It has leading technology in the Matter solution promoted by the alliance.” The author consulted the data and showed that Matter, “Project Connected Home over IP” or “CHIP”, aims to provide Provides interoperable, reliable, and secure connectivity across Internet of Things (IoT) devices and networks, and Apple has a 46 percent share of the Matter wireless solution as a source code contributor.

He also said excitedly: “If there is no major problem with the Matter 1.0 SDK, an upgraded version of 1.0 will be launched at the end of this year, and this product will definitely be launched in the United States next year. Amazon has announced the day before yesterday that all products will be upgraded to Matter support, so everything The era of interconnection is not far away. It will take time, and we believe that China’s standards will also be launched, and the unified standard will make the IoT market bigger.”

Cost- and power-optimized solutions for diverse applications and ecosystems.Zhou Wei pointed out that Bluetooth technology shines in consumer applications, but developers around the world are using face technology to continue to advance in next-generation use cases such as industrial asset tracking, large-scale sensor networks and connected lighting control. And Silicon Lab launched BG22, which is the industry’s first 5.2 Bluetooth chip, which can be powered by a button battery for 10 years, which is one of the few low-power products in the industry. We also have MCU PG22, which is also the MCU that supports low power consumption.

The Internet of Things has infinite possibilities, and the ecological chain of the Internet of Things will also have infinite possibilities. Silicon Lab is a company committed to being an independent, IoT-focused enterprise. The company has been innovating for the past 15 years, striving for breakthroughs in security, connectivity, ease of use and reliable connectivity. The proportion of Silicon Lab’s IoT business in the company’s revenue continues to rise. From the perspective of revenue, the IoT’s turnover exceeds 550 million US dollars, which is close to 60% of the total revenue.

He analyzed and pointed out that the Internet of Things is not a simple branch, but the coverage of indoor and outdoor scenes. Taking the construction of the Internet of Things mainly based on smart homes as an example, he analyzed that the key core is to seamlessly combine indoor and outdoor scenes. He introduced Silicon Lab’s solution for indoor IoT scenarios. In indoor scenarios, the effectiveness of connection and data transmission is crucial. Silicon Lab mainly promotes AoX positioning solutions. At present, mature solutions with low power consumption and effective transmission distance of 1 meter have been provided to customers.

Zhou Wei also emphasized that the Wireless GecKo second-generation wireless Soc platform launched by Silicon Lab has enhanced security, ultra-low power consumption, high performance and integration. The CPU consumption of this platform is reduced by more than 50%, and the RX current can be reduced by more than 60% when using DC/DC. In the scheme, the MIPS is increased by 100%, and the PA is fully integrated. Silicon Lab will continue to focus on the implementation of wireless communication technology in the IoT field in the future, and launch a more power-saving, healthier and simpler wireless Soc platform to serve users around the world.
