In 2024, the topic of short-range Internet of Things technology is still hot, and customers' attention to the technology is mostly focused on cost, power consumption, transmission rate, transmission distance, positioning accuracy, etc., coupled with diverse application market demands, the short-range Internet of Things industry continues to burst out innovation and vitality.
On August 29, the "IOTE 2024· Shenzhen Wi-Fi& Bluetooth & NearLink Short Distance iot Technology Seminar "jointly planned by Shenzhen Internet of Things Industry Association and IOTE Internet of Things Exhibition was held in Shenzhen World Convention and Exhibition Center (Bao 'an New Hall).
Chip Technology director field application engineer Huang Liangjun, Tai Ling Micro business development director Liang Jiayi, Tai Chip Semiconductor Vice president Li Shaohui, Lierda local wireless product Department general manager Zhang Yulong, Lanke Xuntong chairman Tan Hui, Keiside Technology senior wireless test solution engineer Qu Xiaotian, AloT Star Map Research Institute industry analyst Lucy a total of 7 speakers to Wi-Fi, Wi-Fi Halow, Bluetooth Low power, and star flash were the topics for professional sharing and open discussion with nearly 400 audience members.
Lucy, industry analyst of AloT Star Map Research Institute of Internet of Things Media, interpreted the newly released "2024 Short-range Internet of Things -Wi-Fi& Bluetooth & Starflash Industry Research White Paper". She emphasized that the growth space of the short-range Internet of Things industry is particularly bright, on the one hand, very many types of terminals have been or will be connected through short-range Internet of Things technology, on the other hand, the lowest short-range Internet of Things technology has been innovating, which will drive the end product function innovation, application market innovation, and industrial ecology active.
Liang Jiayi, Business Development Director of Tai Ling Micro, shared the research progress of Bluetooth's latest high-precision ranging technology - Bluetooth Channel Sounding. Bluetooth channel detection is an important new feature of the upcoming Bluetooth 6.0 core specification, the use of phase ranging technology, can initially achieve a measurement accuracy of +/-50 cm in the range of 100 meters, suitable for proximity solutions such as Bluetooth "Find My", digital keys, human-machine interface equipment, safety production. At present, Teling Microelectronics - has fully supported Bluetooth channel detection technology.
Huang Liangjun, director field application engineer of Chip Technology, highlighted the ultra-low power consumption characteristics of many of the company's wireless products. The SiWx917 supports the Wi-Fi 6+BLE 5.4 specification and is based on a series of advanced design ideas, making the service life of the 1000mAh battery more than twice that of the battery life of ordinary wireless products. BG2x series Bluetooth SOCs also have excellent low-power performance, with an ideal life of more than 5 years for the CR2032 button battery and more than 10 years for the CR2354 button battery. In addition, Chip Technology successfully introduced the current cutting-edge Bluetooth channel detection design, security protection mechanism, energy collection design based on the environmental Internet of Things, and edge AI/ML design, supporting users to quickly complete innovation and differentiation, which are also the leading advantages of CHIP Technology in the industry.
Li Shaohui, vice president of Taixin Semiconductor, emphasized the advantages of Wi-Fi Halow's long transmission distance and strong penetration. The company's Wi-Fi Halow chip TXW8301 has been mass-produced at present, with a physical layer bandwidth of 32.5Mbps and a working band of Sub-1GHz. It can simultaneously transmit 4 channels of 1080P full HD video within 1.2km in an open test environment. In the wireless wall test, the transmission rate of 4 floors apart is still 4Mbps; Such characteristics are suitable for application in overseas smart home, smart agriculture, industrial Internet of things and other vast areas. In addition, Taixin also introduced a Wi-Fi Halow/Wi-SUN dual-mode chip TXW8311, integrating two types of technical capabilities to meet smart grid, smart city, smart lighting and other applications.
Zhang Yulong, general manager of Lierda Local Wireless Product Department, introduced Lierda star flash product line planning and star flash module performance in detail. EB21 series is positioned as a cost-effective transparent SLE, with lower power consumption, high speed, strong anti-interference, and long distance characteristics than BLE. UB37/DB37 is designed for Wi-Fi 6+BLE 5.2+SLE 1.0 three-mode integration, the uplink rate is significantly increased, the number of connections is increased by 4-8 times, and the anti-interference and anti-multipath capabilities are improved, applicable scenarios include IPC, TV, set-top box, sweeper, driving recorder, etc. DB35 is the currently developed SLE and low-power Wi-Fi 6 module, which is characterized by ultra-low power consumption, and the minimum sleep power consumption can reach more than 80 uA in DTIM10 mode.
Tan Hui, chairman of Lanke Xuntong, analyzed the key technologies of the integration of the Internet of Things and artificial intelligence, including machine learning, deep learning, edge computing, etc., especially the deployment of edge AI has become a trend of product innovation, and edge AI will make products take the lead in terms of delay, bandwidth, security, and energy efficiency. Focusing on AloT smart iot applications, Lanke Xuncom has a close cooperation relationship with Nordic, providing customers with smart Bluetooth modules and software development, cloud and App development intelligent product development and services, and one-stop iot solutions.
Qu Xiaotian, senior wireless test solution engineer of Keisight Technology, summarized Wi-Fi7 - has important improvements in bandwidth, modulation mode, spatial stream number, signal transmission mechanism and other performance, while Wi-Fi7 products put forward higher requirements for EVM indicators reflecting the quality of signal transmission, which means that test instruments/instruments are also facing higher measurement accuracy challenges. Keysight owns the ncEVM spectrum analyzer (Noise Correction EVM) through a series of mechanisms to eliminate or reduce the receiver internal noise impact on the signal, significantly improve the accuracy of EVM measurement, to ensure the reliability of the product.
There is no lack of hot spots in short-range iot technology, and there is always room for optimization and upgrading for power consumption, performance, cost and other demands that users are most concerned about, which continues to attract new enterprises to enter and old enterprises to take root.
Ulink Media and IOTE iot Exhibition are willing to work together with all parties to build an open, inclusive and valuable short-distance iot communication platform to promote the robust growth of the industry!
