This article describes power supply infrastructure construction methods which are considered from U-City infrastructure. For the existing city and town, it is one the issue to find an economic method to construct outside infrastructure including ubiquitous service device. Because the economic construction method could minimize the construction budget which cost big portion of U-City. And the power supply infrastructure is the fundamental layer to keep network and service layer stable. This paper suggests several ways to construct methods with keeping pre-constructed underground power cable by attaching inexpensive power nodal controller
working in Zigbee network and introduces how to monitor and manage the status of power supply to network and service device. Keywords: U-City, USN, Power Supply, Infrastructure, ELB
