2. Installation Guide for Epoch-HP
2.1 Environmental Requirements
2.1.1 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.
Table 1 – Epoch-HP Models
Epoch-HP RF Repeater
User Manual V1.1
Advanced RF Technologies, Inc. Proprietary Document Page 7 of 36
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-HP has a maximum gain of 95 dB, it requires an
isolation of at least 108 ~ 110 dB.

Epoch-HP RF Repeater
User Manual V1.1
Advanced RF Technologies, Inc. Proprietary Document Page 8 of 36
2.1.2 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.

2.2 Warnings and Hazards
Operating the Epoch-HP with antennas in very close
proximity facing each other could lead to severe
damage to the repeater.
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-HP 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-HP will void all warranties.

2.3 RF exposure warning
Important Safety Information
In order to satisfy the FCC RF exposure requirements, you must ensure that the
installation complies with following:
For INDOOR use, an omni-directional antenna with a maximum gain of 3 dBi can be
used with this unit. Service antenna is connected to the Server port in the Epoch-HP via
a cable with typical 1~10 dB loss in accordance with the length of the cable.
Service antennas must be positioned to observe minimum separation of 50 cm (~20
inch) from all users and bystanders. For the protection of personnel working in the
vicinity of service antennas, the following guidelines for minimum distances between the
human body and the antenna must be observed.
The installation of an service antenna must be such that, under normal conditions, all
personnel cannot come within 50 cm(~20 inch) from any service antenna. Exceeding this
minimum separation will ensure that the employee or bystander does not receive RF
exposure beyond the maximum permissible exposure according to section 1.1310
(Limits for General Population/Uncontrolled Exposure)
For OUTDOOR use, an directional antenna with a typical gain of 12 dBi can be used with
this unit. Donor antenna is connected to the donor port in the Epoch-HP via a cable with
typical 1~10 dB loss in accordance with the length of the cable.
Donor antenna must be positioned to observe minimum separation of 152 cm (~ 5 ft)
from all users and bystanders. For the protection of personnel working in the vicinity of
service antennas, the following guidelines for minimum distances between the human
body and the antenna must be observed.
The installation of an donor antenna must be such that, under normal conditions, all
personnel cannot come within 152 cm(~5 ft) from donor antenna. Exceeding this
minimum separation will ensure that the employee or bystander does not receive RF
exposure beyond the maximum permissible exposure according to section 1.1310

AGC Mode
AGC (Auto Gain Control) adjusts the variable gain of the repeater to ensure a
constant specified output power of 37, 40 or 43 dBm (depending on the Epoch-
HP model). The functionality of the AGC feature is assured under the condition
that the input BTS signal is within the specified AGC range and that sufficient
isolation exists between antennas. 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. By
default, the AGC Level is set to maximum output power in each link.
By default,
Uplink Tracking
is not checked. Once both AGC and Uplink Tacking
are
checked, this allows the user to set the AGC level in the downlink only. The
default values that will be displayed on both Downlink and Uplink AGC Levels are
the maximum output power as shown in the table below:
Output Power Level Default Downlink AGC Level Default Uplink AGC Level
5 W 43 dBm 33 dBm
10 W 40 dBm 30 dBm
20 W 37 dBm 27 dBm

65 to 95 dB -52 to -22 dBm
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-HP 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 45.0 dBm
(factory set value for the 20 W model), a Hard Fail alarm would occur if the
downlink over power value was greater than 45.0 dBm (43 dBm is the maximum
composite power allowable). Similarly, a Soft Fail alarm would occur if the
downlink over power value was greater than 44.0 dBm but less than 45.0 dBm.
Vice versa, the same example is also applicable in the uplink side.
