ADAD--SS--9180 Repeater 9180 Repeater
• The AD-S-9180 is a point-to-multipoint, frequency-shifting repeater
system that overcomes the antenna isolation problem in conventional
repeater system.• Each AD-S-9180 can support 2 or 4 channel frequencies, and may be
connected in parallel for higher number of channels.
• Comprises of Master Unit (Direct or Wireless Coupling) and Remote Unit.
• Available in GSM-DCS, GSM-GSM and DCS-DCS.
• Wireless remote and local monitor function (OMT).
• Optional powerful remote repeater network administration (OMC).

Benefits of ADBenefits of AD--SS--91809180
• Eliminate donor antenna isolation problems through frequency translation.
• Fast rollout and fast coverage leads to fast return on investment.
• Low build out costs.• For GSM network, no planning of BSS parameter
• No microwave link and no 2Mbit- connection needed.
• Less antennas and cable usage, and much lighter steel hardware.
• Easy to locate site for installation & coverage.
• Expands coverage areas in rural, tunnels, in-building, canyons and
highways.
• Platform for subscriber growth.

Considerations
• Mounting surface suitable to support
chassis’ weight:< 51kg
• Power outlet within 4m.
• Terminate unused
antenna ports with
a 50-ohm terminator.
• Safety ground
within 4m.

Mounting to a WallMounting to a Wall
Procedures
a) Fix mounting rack to a wall with 4 expansion bolts (M10×100). If the
mounting surface is not strong enough, add 2 more expansion bolts tothe upper mounting rack.
b) Raise the chassis and position it over the mounting rack. Ensure the 2
rack nuts on left and right upper corners of rear chassis is engaged into
the hook of mounting rack.
c) Open the chassis door lock by loosening the 4 bolts on four corners of
chassis cover, using the special key in anti-clockwise direction.
d) Tighten the inner hexagon bolts (M8×80) to mounting rack.
e) Close the chassis cover, tighten the bolts on four corners and lock it.
Installation is accomplished.

Procedures
• Fix the mounting rack with 2
U expansion bolts to a pole(Φ65~75). If the diameter of
the pole is larger than Φ75,
one set of special clamp
should be ordered to install
the repeater.
• The remaining steps are as
same as the wall-mounting
type.
