1. Installation Guide for Epoch-S02-8002W
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 donor and server
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.
To prevent feedback, the donor and server antennas must be separated
by 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 gain of the repeater.
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-S02-8002W has a maximum gain of 96 dB, it requires
an isolation of at least 103 ~ 105 dB.

User Manual V1.0

1.1.2 Line of Sight
The donor antenna which points towards the base station typically 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 the 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 server antenna in direct line of sight of the
coverage area is also necessary.

User Manual V1.0
Advanced RF Technologies, Inc. Proprietary Document Page 7 of 33
1.2 Warnings and Hazards
Please maintain a safe distance of 27 cm while operating near the donor and the
server antennas (assuming the maximum gain of either of the antennas do not exceed
15 dBi).
MPE WARNING!
Working with the repeater while in operation, may expose the
technician to RF electromagnetic fields that exceed FCC rules for
human exposure. Visit the FCC website at www.fcc.gov/oet/rfsafety
to learn more about the effects of exposure to RF electromagnetic
fields.
WARNING! EXPOSURE TO RF
In installing donor or server antennas, avoid close proximity to
overhead power lines or high power components. Contact with
high power components will severely damage the repeater and may
cause serious injury and/or death to the user. Exercise extreme
caution when installing antennas near high power lines.
WARNING! HIGH VOLTAGE
Tampering with the modules within the Epoch-S02-8002W
repeater exposes the user to electric shock and the risk of
damaging the unit. DO NOT TAMPER with modules within the unit.

2.1.3 Control Menu
2.1.3.1 General Setting Window
AGC Mode
AGC (Auto Gain Control) adjusts the variable gain of the repeater to ensure a
constant specified output power of 33 dBm. The functionality of the AGC feature
is assured under the condition that the input BTS signal is within the specified
AGC range (-63 to -23 dBm) and that sufficient isolation exists between
antennas (≥ 109 dB). By default, the
AGC ON
box is checked. To manually
change the gains in both the links,
AGC ON
must be unchecked.
If
AGC ON
is checked and
Uplink Tracking ON
is unchecked, the user can specify
the AGC level in the downlink and in the uplink respectively @ 0.5 dB step (0 to
33 dBm). By default, the AGC Level is set to 33 dBm in each link.
By default,
AGC ON
is checked and
Uplink Tracking ON
is unchecked, this allows
the user to set the AGC level in the downlink and uplink. If
Uplink Tracking ON
is checked, then the user can set the AGC level in the downlink only.
Downlink/Uplink HPA Mode
The HPA mode enables the user to turn the HPA on or off. If the HPA is turned
off on either link, the Epoch-S02-8002W will not operate properly. Both HPAs
needs to be turned on for the RF portion of the repeater to work in both
directions (downlink and uplink). By default, the
Downlink/Uplink HPA ON
box is
checked.

Either or both HPAs can be turned off for troubleshooting purposes during an
installation process.
Uplink Tracking/Offset Modes
Uplink tracking mode enables or disables the
Uplink Tracking ON
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 ON
is checked, and the
Uplink
Tracking Gain Offset
is set to 3 dB, the uplink gain would be 77 dB.
By default, the
Uplink Tracking ON
box is not checked. If it was checked, then
the default
Uplink Tracking Offset
is set to 3 dB. This means that the uplink gain
will track the down link gain and will be 3 dB less.

In the event of a hard fail alarm, the control board will shutdown the HPA (both
uplink & downlink) for 30 seconds and then turns on the HPA to check for a
repeated hard fail occurrence. If the next two occurrences sense a hard fail, the
control board will shutdown the HPA for 20 minutes (total of three consecutive hard
fails). After 20 minutes, the HPA will automatically come back alive and the control
board will check if the Hard Fail alarm has cleared. If it has not, the same process
will continue as mentioned above.

The example below distinguishes the difference between an over power soft
failure and an over power hard failure:
The threshold value for the downlink over power parameter is set to 35.0 dBm
(factory set value), a Hard Fail alarm would occur if the downlink over power
value was greater than 35.0 dBm (33 dBm is the maximum composite power
allowable). Similarly, a Soft Fail alarm would occur if the downlink over power
value was greater than 34.0 dBm but less than 35.0 dBm. Vice versa, the same
example is also applicable in the uplink side.

4.2 Common Installation Problems
Problem Possible Solution
A serial port is
not available on
the PC (only has
a USB Port)
You would need a USB-to-Serial adapter so that it can connect
to the straight-through serial cable that is included with the
repeater.
The power
green LED on
the front panel
is not lit.
Option 1: Check if the power supply switch is turned on by
opening the second door of the repeater.
Option 2: Check if the control board switch is turned on by
opening the second door of the repeater.
OMS Software &
Laptop - No
Communication
Option 1: Please verify that the serial cable is a straight-
through serial cable (use the one that came with the repeater).
Option 2: Verify that proper COM port has been selected and
the Tx and Rx LEDs are lit green and blinking periodically on
the Status Window.
Status Window –
Weak Signal or
Donor RSS
Option 1: Check that the donor and server antennas are
connected to the proper antenna ports on the repeater.
Option 2: Check if the current OMS software loaded is the
same version as the one provided with the repeater. If it is
Table 9 - Tx and Rx LEDs
Epoch-S02-8002W RF Repeater
User Manual V1.0
Advanced RF Technologies, Inc. Proprietary Document Page 29 of 33
not, install the version of the OMS software from the CD
provided.
Option 3: Reposition or rotate the donor antenna around until
a stronger signal is received.
Low Isolation or
Oscillation
Increase the separation between the donor and server
antennas by moving the antennas around or by rotating them.
Downlink/Uplink
VSWR Alarm
Check the cabling because RF signals maybe leaking and also
verify that the connectors are tightly secured.
Downlink/Uplink
Input Power
Overload Alarm
Option 1: Add an attenuator after the donor/server antenna to
reduce the strong donor/server signal coming into the
repeater.
Option 2: If the repeater is connected to a DAS, there’s a good
chance the DAS system could cause a strong signal to come in
on the uplink side of the repeater, causing an
Uplink Input
Power Overload
alarm. If this happens, add an attenuator on
the uplink side of the repeater or control the signal coming in
from the DAS.
Option 3: An oscillation in the system could cause this alarm.
Check if there is sufficient separation between the donor and
the server antennas.
Downlink/Uplink
Over Power
Alarm
Option 1: Add an attenuator after the donor/server antenna to
reduce the strong donor/server signal coming into the
repeater.
Option 2: An oscillation in the system could cause this alarm.
Check if there is sufficient separation between the donor and
the server antennas.
