WICS REPEATER

(WCDMA Interference Cancellation System)

1.WICS Repeater 1.1 introduction This instrument is an ICS (Interference Cancellation System) for the repeater of W-CDMA system, which receives forward signal and backward signal thought the donor and service antenna. It amplifies the received signals and sends them to base • station and mobile to get more strong signal. During this process, it cancels the interference signal between the donor and receiving antenna.

1.2 ICS concept

2. Disadvantages of other types of repeater 2.1 Disadvantages of RF repeater  RF 중계기는 Outdoor로 사용 시 고 출력으로 사용이 어렵다.  not transmit high power outdoor. RF RFrepeater 중계기는can Outdoor 설치 시 설치 장소 output 선택이at 어렵다.

•

 RF RF 중계기는 안테나간 인해 측으로 Feed-back되어 발진의 문제를 일으킨다.  repeater has a lots Isolation문제로 of limitation to find the출력신호가 installation입력 place.  RF repeater can not use for outdoor service due to oscillation of feedback signal.

2.2 Disadvantages of Optic and frequency change repeater  Optic repeater needs master and slave repeater and high price. •

 Optic repeater needs high installation fee to put optical fiber to get transmit path.  Frequency change repeater has low frequency usage efficiency  Frequency change repeater also needs master and slave repeater and high price.

3. Advantages of ICS repeater 3.1 Advantages of ICS repeater  ICS repeater can solve the isolation problem of RF repeater and installation cost are chipper than Optic •

repeater with same service coverage.  ICS repeater can use full frequency range compared to frequency change repeater.

Mobile WiMAX Optical Repeater (DAS-10W)

23.Mobile WiMAX Optical Repeater(DAS-10W) 23.1 System introduction • DAS-10W is a mobile WiMAX optical repeater using digital signal processing technology for SPRINT NEXTEL. As optical repeater does, it is connected with base station(RAS) and cover the shadow area to increase the coverage. The operating frequency is 2495 ~ 2590MHz allocated for SPRINT NEXTEL. It will used in indoor or underground floor service. A signal transmission using digital signal processing instead of analog processing has an advantage of longer transmission distance and is easy to distribute the signal to multi-sector, which is effective to design and manage the system. Since duplexing method is a TDD, a repeater should be able to synchronize the frame. • • The system construction is very flexible to add the new path up to 3 sectors and 2 branches per each sector. Therefore, there can be max. 6 branches available. The each sector uses only one LD and optic signal splitter to have two branches. All RUs are connected in cascade manner. Each sector uses one PD to make reverse link path with a base station(RAS). • A notebook can be connected with MHU and RU to see the system status like a optic path delay, output power level, operating frequency band, attenuation status, each alarm status, etc.
