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.

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.
2.2 Disadvantages of Optic and frequency change repeater
•
RF repeater can not transmit high power output at outdoor.
RF repeater has a lots of limitation to find the installation place.
RF repeater can not use for outdoor service due to oscillation of feedback signal.

13.1 MHU main functions
It is outdoor main instrument which sends and receives signals with base stations or other repeaters and
monitoring of subordinate instruments between UROU and URRU is available
For the down-link path antenna input port sometimes has higher other service provider signal and noise, it causes
spurious signal. It uses SAW filter to distinguish FA and handle them separately which guarantees input dynamic
range 3) For the input of UROU and URRU, it provides the same function of above FA selection function
Max. optic cable connection is 1 Km
Signal transmission between MHU and subordinate instruments is done by IF signal, we use accurate 10MHz
OCXO for the frequency stability(0.01 ppm) and good frequency deviation

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.
