1. A ubiquitous home network system comprising:
- a universal remote controller for converting a control command (CC-UC) according to a user'"'"'s command (UC) into a radio frequency (RF) signal (RF-URC) to emit the RF signal (RF-URC);
at least one or more control nodes for converting the control command (CC-UC) according to the RF signal (RF-URC), received from the universal remote controller, into a control signal (CS-CN) to comply with control targets and emit the control signal (CS-CN); and
a signal repeating means for determining whether the arrival destination of the converted control signal corresponds to the converting control node, and, when the arrival destination does not correspond to the converting control node, for returning the received control signal to the signal converting control node such that an RF signal can be re-transmitted.

Abstract
A system for processing data in a ubiquitous home network is provided. The system uses RF signals based on combination of the remote-controller and the ubiquitous sensor network (USN) technologies and integrally controls a plurality of control targets. Although the remote-controller is spaced relatively far apart from the control targets, the system can control the control targets only if the spaced distance is within the range of an RF signal. As well, the system can automatically control the control targets based on the information detected by the respective sensor nodes.

8. A ubiquitous home network system comprising:
-
a sensor node for detecting information from a surrounding physical environment, converting the detected information into an RF signal (RF-SN), and emitting the RF signal (RF-SN); a home network server for emitting an RF signal (RF-HN) of a previously set control command that corresponds to the RF signal (RF-SN), received from the sensor node; at least one or more control nodes for converting the RF signal (RF-HN), received from the home network server, into a control signal (CS-CN) to comply with control targets, and emitting the control signal (CS-CN); and a signal repeating means for determining whether the arrival destination of the converted control signal corresponds to the converting control node, and, when the arrival destination does not correspond to the converting control node, for returning the received control signal to the signal converting control node such that an RF signal can be re-transmitted. - View Dependent Claims (9, 10, 11)
