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.

Donor Server

RF Repeater

Figure 1 - RF Repeater Oscillation

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.

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.

1.2 Warnings and Hazards

WARNING! ELECTRIC SHOCK

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.
Opening or tampering with any modules inside the Epoch-S02-

8002W 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.

www.fcc.gov/oet/rfsafety

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-S02-8002W with antennas in
very close proximity facing each other could lead to

severe damage to the repeater.

FCC Part 15 Class A

NOTE: This equipment has been tested and found to comply with the limits for a
Class A digital device, pursuant to part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment. This equipment generates,
uses, and can radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to
cause harmful interference in which case the user will be required to correct the
interference at his own expense.
