Based on the analysis of business characteristics and architecture of TD-LTE, it gives the impact of high bandwidth, high den-sity station demand on the existing transmission network, especial y the chal enges faced by the access network. It proposes a loop upgrade in the access equipment. According to the comprehensive business district division and combining with the exist-ing TD-LTE network characteristics, the base station access trunk cable is built to implement business grid management and intensive light coverage of hotspot region, to solve LTE network coverage and ful service access of the urban hotspot region.
