Abstract: An optical network system for providing wireless broadband services is provided. The optical network system may include an optical line terminal (OLT); and at least one optical network unit (ONU), wherein the OLT broadcasts downlink data to the ONU with the aid of a light source and the ONU transmits data to the OLT through a predetermined optical wavelength. Therefore, it is possible to easily identify what terminal has transmitted an optical signal to a center based on the wavelength of the optical signal and to reduce the consumption of optical fibers between the center and a number of access points (APs).

Abstract: The present invention proposes a wavelength division multiplexing-passive optical network (WDM-PON) system which transmits downstream data to an optical network unit (ONU) as an optical line termination (OLT) receives seed light from a spectrum-sliced external light source module. One characteristic of the proposed WDM-PON system is that optical transmitters of the OLT and ONU are operated regardless of optical wavelength. Another characteristic of the proposed WDM-PON system is that a conventional TDMA-PON (E-PON or G-PON) ONU can be accommodated without a change.

Abstract: A real-time location tracking method is provided to enable a user to demand location tracking to a tracked terminal through a tracking terminal, so that the tracked terminal can offer location information in real time according to the demand. A tracked terminal(120) combined with a mobile communication function and a GPS(Global Positioning System) function in integrated type receives a GPS signal to calculate location information in real time. A transmission request for the location information on the tracked terminal(120) from a tracking terminal(140) is decided on. If the request exists, the location information and an intrinsic ID are transmitted to the tracking terminal(140). It is decided whether a transmission mode for transmitting the location information and the ID is an automatic mode or a manual mode. In case of the automatic mode, it is decided whether the transmission mode is a transmission period mode. If so, and if a preset transmission period elapses, the location information and the ID are transmitted to the tracking terminal(140).
