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.

Server

RF Repeater

Figure 1.1.1 RF Repeater Oscillation

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.

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.

1.2 Warnings and Hazards

WARNING! ELECTRIC SHOCK

Tampering with the modules within the Epoch-S02 Repeater
exposes the user to electric shock and the risk of damaging the
unit. DO NOT TAMPER with modules within the unit. Opening or
tampering with any modules inside the Epoch-S02 will void all

warranties.

WARNING! HIGH VOLTAGE

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! EXPOSURE TO RF

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
to learn more about the effects of exposure to RF electromagnetic
fields.

User Manual V1.1

MPE WARNING!

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).

WARNING!

Operating the Epoch-S02 with antennas in very close
proximity facing each other could lead to severe
damage to the repeater.

1.3 Tools and Recommendations for Installation

The following may be necessary (not required) for installation of the repeater:

1. Crescent Wrench or drill with drill bit attachment of …

2. Philips Screw Driver

3. Lift, Ladder, or boom truck

4. Spectrum Analyzer

5. Sweep Tester

6. Signal Generator

7. Pilot Scanner

8. RF Power Meter

9. Voltmeter

10. Coaxial cables

11. Compass

12. Laptop or PC with an RS-232 serial port (with Epoch-S02 OMS V4.01

Software installed)

The list above may vary depending on if brackets are used to install the repeater.
Bring additional tools that may be useful in installation. It is recommended that
two people install the Epoch-S02 Repeater system.

1.5 Step by Step Instructions for Installation

1.5.1

Repeater Setup

1. Mount the Repeater Bracket (Option)
Position the I-shape repeater bracket (ISRB01) at the desired location.
Using the 8 screws (SC01) provided, fasten the bracket securely.

2. Attach Repeater to the Mounting Bracket (Option)
Using the 4 bolts (BLTS01) provided, fasten the repeater (Epoch-S02) to
the bracket.

3. Open the Epoch-S02
Open the front door of the repeater cabinet by using the key (KEYS01)
provided. There are two locks integrated into the door latches. One key
works for both locks.

** Please keep the cabinet door open fully during the installation until
you are instructed to close the cabinet. When opening the door, wait
until the latch clicks to prevent inadvertent closure of the doo .

r

4. Connect the Power Source and Ground Wire
Make sure that the power switch inside the repeater is off before
connecting the power cable. Connect the power cable to the power
source. Connect the ground wire (GNDSTD01) to the ground connector.

** Before connecting the power cable to the power source, make sure that
the voltage source is 110 V.

5. Connect the Donor Antenna
Connect one end of the cable to the Donor Antenna and the other end to
the repeater Donor on the bottom of the Epoch-S02.

6. Connect the Server Antenna
Connect one end of the cable to the Server Antenna and connect the
other end to the repeater Server on the bottom of the Epoch-S02.

7. Initialize the Epoch-S02
Using RS232 straight through serial cable, connect one end of the cable
to the Epoch-S02’s NMS port located on the bottom of the repeater and
the other end to the laptop’s serial port.
