Research And Design Of LTE FDD Network Planning In Luoyang Xigong District

The ever-changing communication technology allows more people to enjoy the entertainment and convenience that the network brings to their lives.However,people not only do the basic things just like chatting online or shopping online but also begin to search new feeling exercise and enjoyment with the age of big data coming.Watching HD video online,video chatting in time and big game online,etc.all need more data traffic and more stable signal quality.The booming of 4G provides more convenient and fast speedy life style to people,but the need to moving big data is continuing increasing,which needs more study on the network distributed and base stations placement to meet people's professional business needs.At present,the LTE networks have been widely deployed and actual operation.While network planning and design is the focus of operators to operate and manage.As the name implies,base station planning refers to plan and design the communication base stations' location,quantity and parameters etc.LTE FDD technologies is widely used in the 4G network due to its many advantages such as strong anti-jamming ability,wide coverage,the frame structure which is relatively simple,relatively small antenna which can save space and facilitate the implementation of the project.Paper introduces the propagation characteristics of radio waves,the key technologies of LTE system,including the OFDM technology,high-order modulation technology and MIMO technology,etc.And it introduces the LTE network coverage and capacity characteristics.Then combining the network planning process with the actual project,it analyzes the development of Luoyang Xigong 4G network status and business needs through the basic data collection.And then set the planning objectives according to the government and business needs and correct the communication model,focusing on analyzing the link budget,at the same time make program design on the basis of xigong present network,then find the vacancies and set up reasonable base stations,apply the atoll simulation planning software to set up various parameters of the simulation,repeatedly adjust parameters of base station in order to achieve the optimal effect of data transmission.Finally the paper puts forward the planning considerations.
