1. Overview
Figure 1.1 RSP-APE-030M Repeater
R-tron RSP-APE-030M Repeater can be used in CDMA service hole spots like in-buildings,
underground and tunnels to cover its service area. This repeater system designed for dual and
simultaneous service, namely, it receives signals from the base station through donor antenna,
amplifies the signals and re-transmits it to one or other mobile terminals. Also, it amplifies the signals
which comes from mobile terminals through distributor antenna and re-amplifies it to base station.
Using local OMT(Operation and Maintenance Terminal) which is connected between repeater
control board and personal or laptop computer, it is possible to check or to control repeater status.

3.1 Block Diagram
Figure 3.1 shows the block diagram of a band Selective repeater.
This diagram is applicable to repeaters for CDMA systems.
3.1.1 Downlink signal path
DL signal path gives a wireless mobile terminal path after receiving signal from base station,
amplifying and noise filtering. Please refer to the following picture 3.1, RSP-APE-030M repeater block
diagram.
3.1.2 Uplink signal path
UL signal path gives a path after receiving signal from mobile terminal, amplifying and noise filtering.
Please refer to the following picture 3.1, RSP-APE-030M repeater block diagram.

4. Installation
4.1 Installation Overview
The following gives you guide how you can install R-tron repeater properly, considering field
situation and installation specific conditions.
4.2 Safety
4.2.1 Purpose
The following information gives you how you can proceed your job correctly and eliminate
dangerous condition.
4.2.2 Application Range
Installation supervisor should check and do the proper thing to check preliminary dangerous
condition.
4.3 Installation information-1
4.3.1 Right-of-way
- The repeater shall be installed in the location owned or leased by the carrier.
- If the repeater is installed in the building, an appropriate space for the installation must be
considered.
4.3.2 Conditions for the Installation space
Repeater should be installed as followings :
In the building
- Avoid certain part which is located something heavy or water tank on the roof, considering
weight balance.
- Select certain place which is good for air ventilation.
- There will be enough space to check the repeater.

4.4 Installation Information-2
The installation of the repeater depends on the types of support, location, and the demand of
the carrier.
Figure 4.1 Antenna & Repeater Installation
4.4.1 General Condition
- Check whether the repeater status is correctly horizontal angle.
- Check whether there is enough space for maintenance and repair.
4.4.2 Installing Band set
- Repeater main box should be installed 8.2 inches at least, above from the ground.
- When you install the repeater main box, do not impact on its installation to other repeaters
maintenance.
- Safety plate should be installed 8.2 inches at least, above from the ground.
4.4.3 Precautions
- Never mount the donor or coverage antenna near a window, where Signal can easily pass through the
glass
- Mount the donor antenna as high as physically possible to the exterior of the building, maximizing
the vertical separation between antennas and pointing away from the building, toward the base station
site.
- Install the antennas taking advantage of any existing building structure Such as brick walls, metal
roofs, or multiple wall structures to additionally attenuate the path between them.
- When using directional antennas inside the building to cover Corridors and hallways, point the
interior antenna away from The donor antenna location .
- In extreme cases, the building configuration may not allow for Such separation and isolation. If
additional isolation is required, Coaxial attenuation may be inserted between the donor antenna and the
repeater , with the potential compromise to the coverage within the building
