With the rapid development of 5G users

5G indoor coverage and experience of operators will face great challenges. The traditional planning method of building by building and scheme by scheme is not conducive to large-scale network construction and effect evaluation in a short time

resulting in a high proportion of low traffi c and low benefi t rooms. In order to ensure the accurate deployment of 5G indoor resources

this paper explores the 5G planning method based on the deep coverage portrait of buildings

in order to provide data support for the planning and construction of 2.6 GHz+700 MHz combined deployment.
