The smart power distribution and utilization communication network is one of the foundations for the smart distribution and utilization system characterized by the wide range covered and large numbers of measuring points.The paper analyses the requirements of bandwidth，delivery time and security in distribution networks access layer from power services，and proposes a solving scheme for a novel power wireless broadband network.The power wireless broadband network is designed at the dedicated spectrum for electric power system and based on time division long-term evolution（TD-LTE）technology.The system can render the service of power consumption information collection，distribution automation，emergency first-aid repair，overhaul and mobile asset management，effectively keeping the transmission of the service information reliable and stable in the distribution and utilization networks.
