Chapter 1. Introduction
1.1 About Celletra’s Cellular RF Repeaters
Celletra’s Cellular CDMA RF Repeaters provide Up-link (UL) and Down-link
(DL) cell coverage extension. They serve as a sophisticated wireless bi-
directional boosters, sensing and re-amplifying the RF cellular transmission in
DL (from the donor base-station to the mobile users), and in UL (from the
mobile-users to the donor base-station), simultaneously. Coverage extension
results in increasing traffic through the donor base station, thus improving
utilization of the Base Transceiver Station (BTS) resources.
Optimization of this network involves -above all- coverage and interference
control. Repeaters in the CDMA network are therefore interactive with the
donor cell and the neighbouring cells, and require flexible tuning and control.
Their effectiveness depends highly on these and other features.
Overall Unique Advantages
The Celletra Repeater product line shares unique features for exceptional
coverage, low impact on the cell, high controllability, and low maintenance
cost. The repeater system guarantees low Noise Figure (NF), high power
efficiency, unique flexibility in installation, and high reliability.

Document No.9130010700 Ver. 1.0 Celletra Proprietary 10
Isolation= PSG - CLSG - CLSA - PSA
Where: Isolation = Isolation between the antennas in dB.
PSG = Signal generator output power [dBm].
CLSG = Signal generator cable loss [dB]
(positive value of loss).
CLSA = Spectrum analyzer cable loss [dB]
(positive value of loss).
PSA = Spectrum Analyzer power reading [dBm].
NOTE: Correct isolation between the antennas ensures the Repeater
will work with the required gain without going into oscillations. If the
isolation is not sufficient, it will be necessary to reduce the Repeater
gain – affecting the Repeater coverage area.
2.4 Mount the Repeater
2.4.1 Precautions
CAUTION
The Repeater is an electrical equipment and should be
treated accordingly.

3.9 Repeater System setup instructions
Note that all power measurements should be made in Peak Mode!
3.9.1 ALC setting
Set the DL ALC to 28 dBm.
Set the UL ALC to 20 dBm.
Cellular CDMA RF Repeater, 0.5W Installation and Operation Manual
Document No.9130010700 Ver. 1.0 Celletra Proprietary 31
3.9.2 Repeater DL Gain Setting
Isolation between the donor antenna and the sector distribution antenna
should exceed the overall Repeater gain by at least 10db.
G max =Isolation-10dB
The reason for this limit is avoid operation near oscillations of the Repeater. It
s on the isolation between the donor and the distribution antennas.
The required DL gain calculation is based on not exceeding 30 dBm output at
full traffic in all channels within the bandpass of the repeater. The DL gain can
be set within a range of 40 to 80dB as long as the gain does not exceed the
G max defined above.
CAUTION
Do not set excessive gain in the DL, otherwise, the Repeater
may enter the ALC state and the Power Control loop.
The gain set-up is done at night, when traffic is nil and only the BCCH is on
air. Leave a margin, related to the number of channels, for peak time
operation
If the repeater is approaching ALC during peak time, reduce the Gain
respectively.
NOTE: If reduced coverage is required, reduce the gains
accordingly.
3.9.3 Repeater UL Gain Setting
Set the Repeater UL gain value to the same value as the DL. This will make
the received signal at the base station somewhat higher than the noise floor. It
will be optimized at a later stage.
Cellular CDMA RF Repeater, 0.5W Installation and Operation Manual
Document No.9130010700 Ver. 1.0 Celletra Proprietary 32
3.9.4 Repeater UL Optimization
1. Drive with a MS to the outskirts of the Repeater coverage area, and
observe the Mobile Tx Power (in test mode). Alternatively, walk indoors to
the worst-case locations.
2. Operate the CCMS software to remotely control the UL gain.
3. If the Mobile Tx Power reaches its maximum power, increase the UL gain
in 1dB steps until the Mobile Tx Power drops by 2dB below its maximum
value.
4. Do not, in any case, set the gain to a higher value than that set in this
Section.
3.10 Noise Rise Check
After completion of the optimization process, verify that the noise at the UL
channel at the BTS does not rise more than 1-2dB due to the Repeater
installation.
In case of noise rise greater than 2dB, decrease UL gain until reaching the
desired noise-rise.
