Research On NB-IoT Planning And Construction Scheme Based On GSM Replacement

This paper first introduces the definition of the Internet of things and the development of the Internet of things at home and abroad.Through the comprehensive comparison of various technologies of the Internet of things,especially from the multi dimensions of coverage,connection,cost and power consumption,it is concluded that NB-IoT is the best choice for the network of narrow band of mass connection.Then,by studying the key technologies of NB-IoT,we further demonstrate the advantages of NB-IoT technology.Then,the NB-IoT network structure planning,network planning and GSM network heavy ploughing are studied,including network structure planning based on reasonable site location,network planning of 1:N,FDD joint network planning,GSM network heavy ploughing and regression calculation method,etc.And by comparing the advantages and disadvantages of the two schemes of the old GSM site and the old TDD site,we get the main selection of the project,based on the best choice of the old GSM site,and introduce the seven schemes under the four scenes,and point out the design principles,the difficulties in the investigation and drawing,and the solutions.The last chapter of this paper mainly discusses the application of the Internet of things in the intelligent city,such as six major fields,such as car networking,smart home,smart city,heavy machinery,industrial equipment and intelligent medical treatment,and how the 5G technology will promote the rapid development of the Internet of things and the challenges that the Internet of things will face in the 5G era.Finally,there is an unlimited vision and prospect for the good prospects of the Internet of things.
