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. Donor Server RF RepeaterFigure 1 - RF Repeater Oscillation
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. Figure 2 - Direct Line of Sight to the BTS Donor Antenna BTS
Epoch-HP RF Repeater User Manual V1.1 Advanced RF Technologies, Inc. Proprietary Document Page 9 of 36 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. WARNING! ELECTRIC SHOCK

Epoch-HP RF Repeater User Manual V1.1 Advanced RF Technologies, Inc. Proprietary Document Page 19 of 36 3.1.3 Control Menu 3.1.3.1 General Setting Window AGC Mode AGC (Auto Gain Control) adjusts the variable gain of the repeater to ensure a constant specified output power of 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 Figure 9 - General Setting Window of the Epoch-H V1.XTable 2 – Default AGC Power Level Values
Epoch-HP RF Repeater User Manual V1.1 Advanced RF Technologies, Inc. Proprietary Document Page 20 of 36 If Uplink Tracking ON is unchecked, then the user can set the AGC level in both links. Models Gain Range AGC Input Range Epoch-HP-05/XX (37 dBm or 5 W Model) 65 to 95 dB -58 to -28 dBm Epoch-HP-10/XX (40 dBm or 10 W Model) 65 to 95 dB -55 to -25 dBm Epoch-HP-20/XX (43 dBm or 20 W Model) 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.

Epoch-HP RF Repeater User Manual V1.1 Advanced RF Technologies, Inc. Proprietary Document Page 28 of 36 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. 3.3.1 General (Fixed Parameter) Alarms Alarm List Soft Fail Hard Fail Comments Over/Under Current O O Soft Fail: Less than 0.5 A @ under current Hard Fail: More than 7.5 A @ over current Over Temperature O O Soft Fail: 158 ~ 185 °F Hard Fail: > 185 °F Synthesizer Lock - O Band selection will not work properly VSWR - O > 1.5:1 Low Isolation/OSC. - O Repeater will be in an oscillating state RF Power - O Will occur in the event of any Hard Fail alarm 3.3.2 Downlink/Uplink Alarms Alarm List Soft Fail Hard Fail Remark RSSI O - Input Power Overload O - Downlink (Forward) Over Power* O O RSSI O - Input Power Overload O - Uplink (Reverse) Over Power* O O Alarms will turn on if the value is not within operable limits specified in the Control Alarm Setting Window.

Epoch-HP RF Repeater User Manual V1.1 Advanced RF Technologies, Inc. Proprietary Document Page 29 of 36 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. 3.4 Default Control Settings 3.4.1 Default General Setting Control Item Setting Value AGC Mode ON Downlink/Uplink HPA Mode ON Uplink Tracking Mode ON Downlink/Uplink Gain 80 dB Downlink/Uplink AGC Level DL: 37/40/43 dBm UL: 27/30/33 dBm (depending on model) Tracking Gain Offset 3 dB a.

Ensure that the door is closed and locked before inspection. b. Check for loose connections to the repeater and antennas. If connections are loose, make sure that all connections are tightly fastened properly. c. Cables and connectors are in good condition. d. Open the repeater door to check that the repeater is turned on. e. Check that all components inside are intact with no unusual wear (e.g., rust, dirt, etc.). f. Ensure that the repeater brackets (if used) are in good condition and that the repeater is securely fastened. 4.2 Preventive Measures for Optimal Operation 4.2.1 Recommendations • Perform the Periodic Inspection Checklist quarterly or semiannually. • Always lock the door to the repeater to prevent unauthorized access. 4.2.2 Precautions • Do not operate the repeater with the antennas in extremely close proximity as this may cause damage to the repeater. • Do not shut down the repeater unless absolutely necessary (in the case where the repeater is a hazard to safety). • Do not change parameters unless instructed to do so by an authorized supervisor. • Do not move the repeater unless instructed to do so by an authorized supervisor. • Do not detach any cables to the repeater unless repair of respective components are necessary.

Check the USB port connection to the computer and the repeater. Ensure that the repeater is turned on and that the connection to the repeater is secure. Blinking GREEN RED The repeater is not receiving any commands from the software. Ensure that the repeater is tuned on and check for proper USB port connection. Blinking GREEN Solid GREEN The repeater is not receiving any commands from the software. In this state, the repeater is either processing or executing a command. Wait for a few seconds for the Rx LED to blink periodically. Blinking GREEN Blinking GREEN Successful Connection. The Epoch-H V1.X and the repeater are communicating successfully. Note: The Tx/Rx LEDs will blink periodically only on the Status Window. 5.2 Common Installation Problems Problem Possible Solution The power green LED on the second panel is not lit. Check if the power supply switch is turned on by opening the second door of the repeater. Software & Laptop - No Communication Please verify if the USB driver has been installed. 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: 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. Table 9 - Tx and Rx LEDs
Epoch-HP RF Repeater User Manual V1.1 Advanced RF Technologies, Inc. Proprietary Document Page 32 of 36 Option 2: 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. Table 11 – Troubleshooting Tips
