Application Research Of The Deep Coverage Model Based On Small And Micro Site Technology In 4G Wireless Coverage

With the construction of 4G network in recent years,the coverage of 4G network has begun to take shape.But on the other hand,it brings the rising cost of network construction and the increasing of weak coverage area.In the past,the limitations of the macro sites to solve the above problems are becoming more and more prominent.We should find the solution of network coverage with more types of sites.This paper put forward: the construction of the micro sites,is the effective strategies to deepen the mobile communication network coverage and improve users' perception.Micro sites and small sites use low cost,low power consumption,high performance,integration,plug and dexterous equipment,complete backhaul access core network in the form of IP.On the basis of analyzing the method and steps clearly,this paper starting from the concept,expounds the existing two weak coverage systematically.Then,it design index and formula derivation according to the different coverage model,study the optimal network mode of small and micro sites under different scenarios,extend these models to indoor and outdoor practical application scenes,analyze and improve the base station equipment layout,thus complete the optimization.This paper provides us three plans of deep coverage including outdoor and indoor.The the paper conducts comparative analysis on the network performance before and after the improvement of the coverage plan,thus verifies the actual enhance of coverage effect.The conclusion of this paper is that: According to the fixed elements to complete the depth of coverage by micro site 、 pico site and femto site.As a representative of the new technology,micro sites and small sites have enriched the single construction mode of operators in the past.The construction of the sites will be gradually transformed into a three-dimensional network of small and micro sites,supplementary macro sites and indoor wiring systems.In this paper,we study the shape selection of small and micro sites according to different coverage scenarios.And through the field experiment,the validity of the coverage model is verified.On the basis of the theory,the conclusion is obtained by using the single site's data in the field,and the implementation process specification of the small and micro sites coverage engineering is finally formed.At present,the network is still short of the application of 4G small and micro sites.This paper presents the application of small and micro station deep coverage.This paper has a certain reference value for the future 4G deep coverage.
