After upgrading from L900M to NR900M,L900M is shut down and only relies on the coverage of L1800M in the current network.The LTE coverage in some areas shrinks.How to accurately and efficiently identify weak coverage areas after upgrading from L900M and achieve LTE intermediate frequency network coverage support at the lowest cost is the focus of this article.At present,the intermediate frequency network of the electric union has been fully deployed.The weak coverage grid aggregation is carried out based on DBSCAN density clustering algorithm to accurately identify the coverage blind spots that need intermediate frequency support.At present,pilot and on-site testing verification have been completed in the provincial capital,and value promotion has been completed in other cities within the province.
