  • Patent number: 6466560
    Abstract: A system and a method for obtaining Ec/Io for a predetermined site for use in positioning a base station for a mobile communication network. Continuous waves having a constant output power and frequencies different from each other are generated by many continuous wave generators. The continuous waves are received from the continuous wave generators so as to measure RSSI of the continuous waves and GPS information. Ec/Io of a predetermined site is measured from the RSSI of the continuous waves and the GPS information. Accordingly, the measurement for positioning a base station is performed with regard to adjacent interference under actual circumstances so that a new base station can be positioned on a proper site.

  • Patent number: 6374119
    Abstract: Disclosed is a mobile communication system and method. A base station (BS) transmits and receives signals using predetermined serving frequency signals. A donor module, coupled to the BS, converts output signals of the BS into intermediate frequency (IF) signals and performs a power control operation on the signals and outputs resulting signals to a path. Each of a plurality of remote modules receives output signals of the donor module through the path and converts the signals into serving frequency signals, then outputs the converted signals to a mobile station (MS) within a blanket area. The remote module converts signals received from the MS into IF signals and outputs the signals to the donor module through the path. The donor module converts the IF signals provided from the remote module through the path into serving frequency signals and transmits the signals to the BS. Therefore, the present invention easily removes blanket areas in a building at a low cost.
