Research On Planning Method Of Rural 4G Network

With the completion of the first and second phase construction of China Mobile LTE,most cities have basically achieved continuous outdoor coverage.Rural construction will soon be launched rapidly,but the decision-making on rural coverage planning indicators,planning methods,coverage schemes and so on are lack of sufficient test data support.Therefore,it is necessary to carry out rapid multi-regional testing to explore the basic situation of rural coverage,the performance of various coverage schemes,and draw the conclusion that it can support the follow-up large-scale construction.Planning methods and planning indicators.The main work of this thesis is as follows:1.Based on the coverage of rural TDD-LTE F band and existing network base station co-site after construction,the coverage capability of TDD-LTE F band is understood through fixed-point test and pull-out test,and the difference of coverage characteristics between plain rural and mountainous rural areas is studied.2.Testing the coverage capability of FDD-LTE 900M and 1800 M in rural scenes,and comparing and calculating the difference of coverage capability.3.By comparing the high-gain antenna test and coverage enhancement schemes with the non-coverage enhancement schemes,an effective low-cost implementation scheme of TDD-LTE F band in rural coverage is found.4.Through the coverage test of 16T16R antenna,the difference between 16T16R antenna and 8T8R antenna in the current network is analyzed,whether it is conducive to the improvement of network coverage.5.Through the comparative analysis of test data,the phased coverage planning methods and indicators are proposed in mobile network construction.The innovation of this study is to focus on the diversity,effectiveness,accuracy and applicability of rural 4G coverage.It is the first time to test the coverage capability of rural F-band and GSM-Hi 900M-1800 M band in a wide range of multiple scenarios,and to study the coverage capability of TDD-LTE F band and FDD-LTE 900 M rural base stations in sub-scenarios,so as to provide theoretical basis for China Mobile Group to formulate long-term rural coverage planning.
