Cost reducing and efficiency increasing is one of the key work of mobile network construction. The idea that choosing different deployment schemes of pico base station on the basis of the subdivided indoor scene

is proposed. It can not only give full play to the product performance of pico base station

optimize the network structure

but also achieve the purpose of cost reducing and efficiency increasing. Three kinds of pico base station indoor depth coverage schemes for cost reducing and efficiency increasing are put forward

and test verification results are given. Furthermore

the coverage effect

cost saving effect and applicable scenarios of the scheme are analyzed and evaluated.
