Design And Implementation Of Low-Rate Data Transmission Module For Narrowband Internet Of Things(NB-IOT)

With the rapid development of informAtization in the smArt city industry,along with the development of emerging technologies such as big data,Internet +,cloud computing,and AI,there has been a huge demAnd for data,and the source of mAss data is more data collection at the perception layer.From the perspective of the scale and development of data transmission requirements in the perception layer,there is a huge industry demAnd for IOT communication technology.Narrowband Internet of Things,as an important part of the Internet of Things technology,is mAinly targeted at the smAll-scale data transmission business with the widest application and demAnd in the Internet of Things industry.This type of business has an overall mArket size of more than 50% in the IOT industry.Due to the development of IOT technology and deep industry demAnd,the needs of the low-speed narrowband IOT industry have also extended from traditional water,electricity,and gas meters to water affairs,environmental protection,meteorology,industry,agriculture,shared bicycles(cars),smArt cities,etc.Life and industry production.This article is mAinly based on the new generation of wide-area narrow-band lowrate IOT communication technology NB-IOT,and analyzes the current smAll data volume data transmission business industry needs and development trends,and designs the transmission module of the new-generation narrow-band IOT technology.The mAin research contents include:1.Analyzed the current development status and trends of the communications industry and the requirements of the narrowband Internet of Things to ensure the advanced nature of this research and the value and significance of the research.2.Sort out the current narrowband IOT technology and industry requirements in the licensed and unlicensed bands in the field of transmission and communication,summArize the technical characteristics of NB-IOT,and ensure the advanced technology of this research and the applicability of large-scale deployment of the industry.3.The needs of the low-rate transmission module for NB-IOT applications are analyzed.On this basis,the software and hardware design are performed,and the detailed design process is listed,which provides the design for the low-rate digital transmission module.Reference solution.4.The narrow-band IOT low-rate digital transmission module designed in this paper was tested for packaging,and finally the SIMulation scenario was tested.The test results show that: in terms of product reliability,product performAnce,and actual application effectiveness,the application requirements of the narrowband IOT are met,and good test results have been achieved.The research in this article is based on the emerging communication solution NBIOT in the wide-area smAll-scale data transmission technology industry,which solves the problem that the current 2G/3G transmission module smAll data acquisition equipment cannot transmit data due to changes in communication technology deployed by the operator's network.The development of the industry provides solutions for lowcost stock business needs,combined with the actual status and needs of the industry.This study can reduce the waste of resources caused by repeated investment in the industry,which has helped the overall NB-IOT technology to meet the actual industry demAnd.Positive meanings such as a smooth transition.
