Research And Implementation Of Integratednet Work In L City

With the continuous development of information technology,it is more and more demand for wireless networks,to meet the user's demand,the major operators exert all over skill.Compared with the previous 2G and 3G networks,LTE(term evolution long)4G network technology has the advantages of faster,better signal and so on.Not only the era of the global industry chain is not in a dream,the more important is the independent enterprises in our country and the international advanced operators standing on the same starting line,make our country independent enterprises have more and better opportunities for development.From a technical point of view,LTE technology has FDD(frequency division duplex)and TDD(time division duplex)two formats.The two standard due to the different duplex mode,so in the design of physical layer more or less exist some differences,but they in signaling technology and is almost the same,which has provided the basis and possibility of the two standard fusion.Merges two LTE and LTE FDD technologies and can not only give full play to the standard two respective advantages,the wireless network resource utilization rate reached a maximum,can also maximize the LTE terminal of industrial scale.In this paper,combined with the design and implementation of LTE integration network,the paper studies and discusses the construction of TD-LTE and FDD LTE hybrid network base station.Firstly,the core technology of TDD standard and FDD standard and the possibility of integration of these two systems are studied.Secondly,the basic situation of L city and the current situation of the network,such as the scale of the present network,coverage,the total amount of business,business density,analysis of the existing problems of L wireless network coverage.Once again combining the characteristics of FDD LTE and TD-LTE,according to the existing problems of L City,set the corresponding network design principles and objectives.Respectively for L City scene with different LTE FDD and TD-LTE network coverage planning,capacity planning and base construction of detailed design,and the L City LTE FDD and TD-LTE financial network simulation and evaluation on the design scheme of adjustment and effect.Finally combined with the L TD-LTE and FDD LTE hybrid network base station after the completion of the new project,the L urban wireless network road data test,from the RSRP,RSSINR,application layer rate and other indicators to analyze,to meet the requirements of the reservation.On the L City TD-LTE LTE FDD and two standard network integration scheme is studied and implemented.Provides a solid foundation for the road of the development of the cause of China's wireless network,to other cities in our country are dual combination of 4G network construction has great guidance and reference significance.
