1INTRODUCTION
Deko3108S is a band selective midi-repeater that supports the iDEN 800 MHz band. The
repeater is specifically designed for the operation of ESMR 800 MHz and is band
selectable in the 800 MHz range [18 MHz or 7 MHz bandwidth].
Deko3108S has switchable and tunable IF-SAW filters. These enable highly accurate
out-of-band-rejection and provide simple, fast procedures for adjusting the pass band
according to the 800 MHz rebanding requirements.
Deko3108S includes the SmartALC power control algorithm that automatically optimizes
the gain setting by learning the actual range of RSSI levels over a user-specified period
of time. The SmartALC algorithm prevents oscillations, reduces the amount of isolation
required by the system and optimizes the system to minimize noise rise at the donor cell
site.
Intuitive Web access monitoring and management GUI is accessible via a local Ethernet
connection (using a cross-cable). An option for remote wireless communication
connection (via a separately purchased modem) is also available.

1.2 MANAGEMENT CONNECTIONS
You can connect to the Repeater using either:

cross-cable
•Wireless remote connection – using an external modem connected to the Ethernet
port using a
cross-cable (modem is purchased separately)
1.3 SMART-ALC FUNCTION
1.3.1 SALC Function
The iDEN midi-repeater includes the Smart Automatic Level Control (ALC) function on
both the Uplink and Downlink power amplifiers to prevent output power from exceeding
maximum allowed output power.
The amplifier includes a directional coupler and a detector that monitor the output
power. The ALC mechanism samples the output power, and decouples and rectifies it.
The ALC mechanism sends a feedback signal to a voltage variable attenuator (VVA)
that, whenever a high input signal is received, attenuates the signal level so that the
output power of the amplifier does not exceed the preset limit.
1.3.2 SALC Description
The Smart Automatic Level Control (Smart-ALC) is an innovative solution for automatic
repeater gain adjustment. Combined with advanced control algorithms, SALC can
perform gradual learning of traffic load characteristics and adjust the Repeater RF Gain
to an optimal value.
Some of the SALC advantages are:
•Network friendly: The SALC periodically learns traffic conditions and set the gain
so that at maximal traffic the repeater output is at maximal value. In all other cases
the gain is constant and the output power follows the BTS fluctuations. This feature
introduces system transparency – the mobile using the repeater is not affected by
repeater existence. Repeaters that blindly amplify the pilot code (minimal
transmission) of a certain base station to maximum output power might generate
network problems (they unnecessarily increase the noise in a certain cell). By
keeping the same gain for full traffic as well as for pilot only transmissions
situations, the Dekolink SALC feature minimizes this effect.
•No adjustments are required: When installing the repeater, the standard
procedure for the technician is to tune the repeater to the desired isolation and gain
values. With SALC, the tuning procedure is accomplished automatically, thus saving

DEKOLINK WIRELESS LTD. DEKO3108S MIDI REPEATER PRODUCT MANUAL
P/N 300XC10031 Rev. BProprietary Data Page 9
precious workmanship and equipment usage time for a “plug & play” foolproof
deployment.
•Uplink and downlink balance is preserved. In previous repeaters, separate
adjustments are required for the uplink and downlink. This repeater requires just
one adjustment for both channels. If the gain of downlink path changes by some
value, the uplink path is changed by the same value. Both channels have to be
balanced for the proper seamless integration of the repeater in the network.
Unbalanced operation bares the risk of reducing the dynamic range of the base
station itself.
•Reduction of isolation problems: .This repeater does not oscillate. Whenever
the isolation drops for some reason the repeater automatically senses the
oscillations and automatically reduces the gain in accordance with the new isolation
conditions. Once the isolation problem is solved the repeater automatically raises
the gain again. This operation is remotely monitored, and if required, remote
controlled.
SALC - Summary: Conventional repeaters often interfere in the network when strong
traffic raises the repeater input signal level, which as a result activates the ALC
algorithm of the system. Once under ALC, the conventional system is no longer in its
linear dynamic range, hence creating interferences in the cell shrinking or expanding
procedures. The Smart ALC solves this problem and thus reduces the need for
adjustments. The repeater does not interfere with the network shrinking or expanding
processes and thus becomes “network friendly“.
This automatic operation practically removes the need to make initial settings for
maximal traffic load conditions and eliminates the need for numerous site visits to take
care of Gain adjustment.
SALC also reduces isolation problems and maintains Uplink/Downlink balance.

1.4 DEKO3108S INTERFACES
Deko3108S is housed in an enclosure with a securely locked door for easy access to the
internal components for connections, adjustment and for service and maintenance.
Most of the required interfaces are located externally; however, the
communication
ports
and the manual RF power selector (for service personnel) are located internally
and are accessed by
opening the Repeater door.
1.4.1 Ports
The antenna and power connections are located on the underside of the Repeater as
illustrated below.

1.4.2 Internal Interfaces
This section describes the Repeater interfaces that are accessed by opening the
Repeater. There are two such interfaces:
•The Ethernet port
•Power level selector – for service personnel only. This connector is relevant only if
the option is enabled from the Web GUI application 4.3.
1.4.2.1 Ethernet Port
During installation, you will be required to open the enclosure door in order to access
the
Ethernet communication port located (on the CMU unit as illustrated below).
Note: The Ethernet communication port is the only port that is relevant to the user.
Figure 1-3. CMU Front Panel
1.4.2.2 Internal Power Selector (for service personnel)
The Max Gain is factory set to its minimum value by default. The RF power level can be
modified either through the GUI (default - 4.3.) or through the internal selector located
in the Repeater (service personnel only).
The Repeater is factory set to allow this configuration
only through the GUI – the
internal selector is disabled.
In order to use the selector in the unit to set the CDMA
power level, the option must first be enabled in the GUI by setting the LBDA Params
Mask (section 4.3); otherwise any changes in setting via this switch are not relevant.
NOTE: The UL and DL LEDs can be used to provide some indication of the UL and DL
signal levels. However, it is recommended to use the WEB access application advanced
monitoring capabilities to monitor and troubleshoot the Repeater.
