Research On Key Technology Of High Performance LTE Network

Nowadays, the primary target of domestic LTE network construction is to increase the coverage area in a high speed. In the process of networking, the interference and the lack of frequency resource limit the LTE network construction. Research on the phenomenons of network frequency overlapping and limitation during the networking procedure has been done in this dissertation and the technical schemes of network parameters adjustment and LTE network coverage reinforcement have also been proposed. Based on these schemes, the type and direction of network parameter adjustment has been designed and verified. The methods proposed in this dissertation possess significant application value in the construction and development of LTE network.In terms of interference suppression, a scheme focused on decreasing the overlapping degree by adjusting the network parameters has been designed in this dissertation. In the scheme, discussions have been carried out by restricting the height of base station, adjusting the downtilt of antenna, and controlling the deflected distance between the base station and standard cellular site. By testifying the design schemes, a series of network parameters and theoretical models possessing guiding significance towards the project have been obtained,In terms of frequency limitation, in order to increase the coverage of network, a scheme using multi-antenna technology and Tower Mounted Amplifier(TMA) technology has been proposed based on explicit engineering application background. The method focusing on increasing the coverage of LTE base station under urban, suburban and rural circumstances is obtained through the discussion of the design scheme. Compared to the traditional scheme of network construction, this method can efficiently reduce the amount of newly constructed base stations and is conductive to lowering the cost for operators.
