Epoch-S02 RF Repeater 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. DONOR ANTENNA BTSFigure 1.1.2 Line of Sight to the BTS Advanced RF Technologies, Inc.

Epoch-S02 RF Repeater User Manual V1.1 2.1.3 Control Menu 2.1.3.1 Gain Setting Figure 2.1.3.1 Gain Setting Window of the Epoch-S02 OMS V4.01 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 User Manual V1.1 By default, the Uplink Tracking ON box is enabled and the Uplink Tracking Offset is set to 0 dB, meaning the uplink gain will always equal the downlink gain.

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.
