User Manual V1.1
1. Installation Guide for Epoch-S02
1.1 Environmental requirements
1.1.1 Antenna Separation / Isolation
Separation between antennas is necessary to prevent oscillation.
Oscillation occurs when the signal entering the system continually
reenters, due to the lack of separation between the input and output
antennas. In other words, the signal is being fed back into the system.
This creates a constant amplification of the same signal. As a result, the
noise level rises above the signal level.
Donor
To prevent feedback, the donor and server antennas must be separated
an appropriate distance to provide sufficient isolation. Isolation is
attained by separating antennas a sufficient distance so that the output
of one antenna does not reach the input of the other. This distance is
dependent on the gains of the repeater and the antennas.
A sufficient isolation value is 13 ~ 15 dB greater than the maximum gain
of the repeater. For example, if the gain of the repeater is 50 dB, then an
isolation of 63 ~ 65 dB or greater is required. In the same manner,
because the Epoch-S02 has a maximum gain of 90 dB, it requires an
isolation of at least 103 ~ 105 dB.

Epoch-S02 RF Repeater
User Manual V1.1
1.1.2 Line of Sight
The donor antenna pointing toward the base station has a narrow beam
antenna pattern. As a result, a slight deviation away from the direction of
the BTS can lead to less than optimum results. In addition, obstacles
between the repeater and BTS may impair the repeater from obtaining
any BTS signal. As a result, the repeater cannot transmit signal to the
coverage area. Therefore, a direct line of sight to the BTS for the Donor
Antenna is vital to the function of a repeater. For the same reason,
placing the coverage antenna in direct line of sight of the coverage area
is also necessary.

AGC Mode
AGC (Auto Gain Control) adjusts the variable gain of the repeater to ensure a
constant specified output power of 24 dBm. The functionality of the AGC feature
is assured under the condition that the input BTS signal is within the specified
AGC range (-45 to -85 dBm) and that sufficient isolation exists between
antennas (≥ 103 dB). By default, the AGC ON box is enabled.
Downlink/Uplink HPA Mode
HPA (High Power Amplifier) is an essential component of the Epoch-S02. The
HPA is the final stage of amplification in the Epoch-S02. The HPA Mode enables
the user to turn the HPA ON or OFF. If the HPA is OFF on either link, the Epoch-
S02 will not operate properly. Both HPAs need to be ON. By default, the
Downlink/Uplink HPA ON box is enabled.
Uplink Tracking/Offset Modes
Uplink Tracking Mode enables or disables the Uplink Tracking feature that sets
the gain in the uplink equaling to the gain in the downlink. The Tracking Gain
Offset is the difference in the uplink and downlink gains. For example, if the
downlink gain is 80 dB, the Uplink Tracking Offset is set ON, and the Tracking
Gain Offset is set to 3 dB, the uplink gain would be 77 dB.
Advanced RF Technologies, Inc. Proprietary Document Page 16 of 31
Epoch-S02 RF Repeater

are loose, make sure that all connections are tightly fastened properly.
3. Cables and Connectors are in good condition.
4. Open the Repeater door to check that the Repeater is on.
5. Check that all components inside are intact with no unusual wear (e.g., rust,
dirt, etc.).
6. Ensure that the Repeater brackets (if used) are in good condition and that
the Repeater is securely fastened.
3.2 Preventive Measures for Optimal Operation
3.2.1 Recommendations
• Perform the Periodic Inspection Checklist quarterly or semiannually.
• Always lock the door to the repeater to prevent unauthorized access.
• Tune the Repeater so that amplification is only within the band selected.
In other words, no amplification of unwanted signal(s) outside the
selected band.

3.2.2 Precautions
• Do not operate the repeater with the antennas in extremely close
proximity as this may cause damage to the repeater.
• Do not shut down the repeater unless absolutely necessary (in the case
where the repeater is a hazard to safety).
• Do not change parameters unless instructed to do so by an authorized
supervisor.
• Do not move the repeater unless instructed to do so by an authorized
supervisor.
• Do not detach any cables to the repeater unless repair of respective
components are necessary.

4.2 Heartbeat Scenarios
If the Heartbeat of the Epoch-S02 is not being received by the NOC, it may be
necessary to send a technician to visit the Epoch-S02 site. Scenarios for no
Advanced RF Technologies, Inc. Proprietary Document Page 26 of 31
Epoch-S02 RF Repeater
User Manual V1.1
heartbeats being sent include consistent Hard Failure (as mentioned in the “Alarms”
Section 2.3) in the following areas:
1. Over Current
2. Over Power
3. Over Temperature
Over Current
The “Over Current” Alarm occurs when the input current from the power
source exceeds 6 Amps. In order to lessen the amount of Amperes
drawn by the Epoch-S02, the control board will shut off components that
draw current (i.e. the HPA).
Over Power
The “Over Power” limits for uplink and downlink are set by the user in the
Alarm Setting Window in the Control Menu. A Hard Failure “Over Power”
Alarm occurs when the output of the Epoch-S02 exceeds the limits
entered into the Alarm Parameter Settings (Over Power limit +1 dBm).
Over Temperature
A temperature inside the box greater than 185º F will cause the Epoch-
S02’s control board to shut down the HPA in an attempt to lower the
temperature inside. Though the Epoch-S02 is equipped with a heat sink
to dissipate heat, extreme conditions, such as very hot temperature, are
dealt with by shutting down heat-generating components (i.e. HPA).
1. Prior to visiting the site, know the temperature of the Epoch-S02 site
on the day that the heartbeat stopped being sent.
2. Observe the ambient temperature surrounding the Epoch-S02 site. If
the weather is hot, it is safe to assume that the outdoor temperature
caused the “Over Temperature” Failure.
3. If the outdoor temperature was or is fairly cool, one can assume too
much heat is being generated within the Epoch-S02.
4. Since the HPAs have been shutdown to dissipate heat, it is safe to
evaluate the repeater by unlocking and opening the front door.
5. Evaluate the inside of the Epoch-S02 and check to see that no
unusual wear exists (e.g. burned, blackened areas, etc.). If you detect
these areas, contact Advanced RF Technologies, Inc. in the “Warranty
and Contact Information” section, Section 5.
