NB-IoT物联网大学生实践创新计划与教学方案设计探讨

Discussion on the College Students’ Practice Innovation Plan and Teaching Plan Design of NB-IoT

NB-IoT又称窄带物联网,是由3GPP标准化组织定义的一种技术标准,工作于授权频谱上,是一种专为IoT设计的窄带射频技术,不同于Zigbee、Bluetooth、Wi-Fi等短距离无线通信技术,它属于低功耗广域网(LPWAN)范畴,通信距离可以达到15 km.LPWAN目前还有一种流行的通信方式LoRa,它工作在免授权的ISM频段上,NB-IoT和LoRa极具发展前景,基于这2种通信方式的生态正在快速建立.NB-IoT大学生实践创新项目以及该技术在教学应用方面的方案设计值得探讨.

NB-IoT (Narrow Band Internet of Things), also known as the narrowband Internet of Things, is a technical standard defined by the 3GPP standardization organization. It works on the licensed spectrum and is a narrowband RF technology designed for IoT. It is different from Zigbee. Short-range wireless communication technologies such as Bluetooth and Wi-Fi, which belong to the low-power wide area network (LPWAN) category, and can reach a communication distance of 15km. LPWAN currently is of a popular communication method, LoRa, which works in the license-free ISM band. NB-IoT and LoRa enjoy great development prospects. The ecology based on these two communication methods is rapidly established. This paper mainly concerns some of the conclusions of leading students to participate in NB-IoT students' practical innovation projects and to explore the design of the technology in teaching applications.
