Abstract：This paper presents the theoretical assessment method and a case study of compliance boundary of human exposure to 5G radio base station. The technical issues related to human exposure to radio frequency electromagnetic fields at 5G frequency band, the determination method of the actual maximum EIRP(time domain average) of 5G base stations, theoretical evaluation calculation formulas and evaluation procedures, etc.，are discussed for the assessment of the electromagnetic environment in real scenarios.

Abstract：In order to meet the business requirements of 5G three scenarios, edge computing technology based on network function virtualization comes into being. Operators should follow the trend of the industry, layout edge computing, which is of great significance to the revitalization of datacenter resources, cloud network collaborative operation. Based on the demand and value of 5G edge calculation, this paper proposes the planning and deployment method of 5G edge datacenter from two aspects of business and cost respectively, and meanwhile puts forward the requirements for the configuration of infrastructure such as power supply and air conditioning in the datacenter.

Abstract：2020 is the year of 5G scale deployment and commercial operation for mobile operators. With the development of major systems of operators towards platform and automation, 5G planning and construction by system platform with cloud computing as carrier, big data as means will effectively assist the rapid implementation of national 5G strategy. First of all, this paper analyzes the overall scheme of 5G site planning based on big data and platform, then analyzes the NR(New Radio) coverage prediction and ability algorithm involved in the scheme in detail, and finally studies the site planning scheme based on the calling of 5G simulation interface.

Abstract：Characterized by complex wireless communication environment, concentrated mobile users and large demand for data services, subway has become the key area covered by 5G network.Combined with 5G network characteristics, this paper analyzes the characteristics and coverage requirements of the wireless communication environment of subway hall/platform and tunnel, and proposes 5G coverage solutions for the newly built and existing subway joint scene.

Abstract：As the package price of 5G deployment is reduced in the early stage, a large number of data drops will impact the 4G network traffic.At present, the commonly used network traffic forecasting model pays little attention to the package price factor, let alone the data fallback effect brought by network standard upgrade.In this paper, a traffic prediction model based on package and standard driving model is proposed, and corresponding optimization and capacity expansion schemes are selected according to the traffic prediction.4G traffic prediction and construction scheme analysis based on college scenes are very important to ensure the network advantages of operators.
