摘要： A Ubiquitous Sensor Network (USN) system using multi-channel having differential radio power and a method of configuring the USN system are provided. The USN system and the method include a sink node performing a communication with a sensor node using at least one or more frequency signal having differential outputs; and a sensor node performing the communication with the sink node using the at least one or more frequency signal. The USN system and the method simultaneously use a control frequency signal having a high output power and a data frequency signal having an output power lower than that of the control frequency signal, thereby reducing a beacon transmission delay, enabling time synchronization between the sensor nodes, and preventing collisions between beacons due to beacon relays among the sensor nodes, so as to configure a more efficient sensor field.
