1Introduction to the Results Real-time remote medical monitoring can address the shortage of public medical resources caused by an aging society. However, the strict requirements for high-performance sensors and long-distance signal transmission hinder the development of such comprehensive monitoring systems. This paper, published by Professor Yang Bin’s research team at Shanghai Jiao Tong University in … Read more
NB-IoT technology, with its advantages of full coverage, low power consumption, and low cost, overcomes the shortcomings of traditional IoT technologies, such as high power consumption, high costs, poor coverage, fragmentation, and difficulty in large-scale applications. It has been applied in various IoT application scenarios, including remote meter reading, asset tracking, smart healthcare, and smart … Read more
Abstract: NB-IoT is an emerging cellular technology that better supports applications requiring large connections, low power consumption, low throughput, low device costs, and high latency tolerance. Compared to LTE systems, the random access channel NPRACH in the NB-IoT system has been redesigned. A detailed analysis of the structural design of NPRACH in the NB-IoT system … Read more
NB-IoT Ultrasonic Remote Water Meter Research data indicates that among ordinary residential water usage, about 75% of the flow rates are between (300-1500) L/h, which can be accurately measured by existing water meters. However, approximately 14% of the flow rates are below (3-18) L/h, which is currently a major area of negative measurement error. The … Read more
The IoT SIM card is a mobile communication access service provided by the three major operators: China Mobile, China Unicom, and China Telecom, for IoT scenarios. It uses dedicated (11-digit or 13-digit) number segments to support basic communication services such as SMS, wireless data, and voice through specialized devices, providing communication link management and terminal … Read more
