Epoch-H (HP/HC) RF Repeater User Manual V1.5 Advanced RF Technologies, Inc. Proprietary Document Page 21 of 60 2.3 Antenna Separation/Isolation Separation between antennas is necessary to prevent oscillation. Oscillation occurs when the signal entering the system continually re-enters, 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. 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-H has a maximum gain of 95 dB, it requires an isolation of at least 108 ~ 110 dB. Figure 14 - RF Repeater Oscillation
Epoch-H (HP/HC) RF Repeater User Manual V1.5 Advanced RF Technologies, Inc. Proprietary Document Page 22 of 60 2.4 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 15 - Direct Line of Sight to the BTS

Advanced RF Technologies, Inc. Proprietary Document Page 43 of 60 5.2 Troubleshooting Guide for Repeater Alarm Status Parameter Troubleshooting VSWR Hard Fail VSWR Over 3:1 1. Make sure connectors are tight at each port. Sweep lines. 2. Use a 50 Ω dummy load, connect it to the Alarming Port to check whether the repeater is faulty. (e.g. if the Down Link is alarming, connect the dummy to the Server Port.) 3. If multiple Server Antennas are connected, connect only one antenna and recheck the Alarm. If the Alarm clears, faulty connectors like combiners/ splitters in the serving line and lightning arrestors (polyphasers) may be causing the problem. Over Power Soft Fail UL/DL Epoch-H(5Watt) 37dBm~38dBm >Max Output Power+1dB 1. Check Input/Gain/Output values in the ‘Status Page’ 2. Check Input Level (If the input exceeds the max rated power, add an Attenuator to the input/ Donor port) 3. Check whether AGC is On (In the case of UL Shutdown, make sure that Tracking is OFF) 4. Factory Setting & Reboot Epoch-H(10Watt) 40dBm~41dBm Epoch-H(20Watt) 43dBm~44dBm Hard Fail UL/DL Epoch-H(5Watt) 37dBm~39dBm >Max Output Power+2dB Epoch-H(10Watt) 40dBm~42dBm Epoch-H(20Watt) 43dBm~45dBm RF Power Soft Fail Invalid Output Level of Gain 1.

Go under ‘Control’ tab and turn off AGC and change gain manually to verify BDA is responding to changes. Recheck the measured values. Low Incoming RSSI Soft Fail Downlink Input Value is less than threshold: PCS/ Cell: -95dBm minimum 1. Ensure proper ports are connected (Donor/ Server). 2. Verify the Donor antenna is pointed toward the correct cell site. 3. Verify the selected band(s) and be sure it is the right band(s) for the area. 4. Please be aware that our bdas typically require well above -85dBm (threshold) of incoming RSSI on the DL side. Under/Over Current Soft Fail Current falls out of the permitted range 1. Factory Setting & Reboot 2. Recheck, if continues, contact Tech Support. Hard Fail Over Temperature Soft Fail Repeater’s internal temperature exceeds the permitted range 1. Factory Setting & Reboot 2. Recheck, if continues, contact Tech Support. Hard Fail Input Overload Hard Fail Input Signal Level increases beyond the set range: PCS/ Cell: -30dBm max input 1. Add attenuator to donor/server antenna (Applicable to DAS) 2. Factory Setting & Reboot Low Isolation Oscillation Antennas are located too close to one another, causing RF output to feed input. 1. Check Input Level. (fluctuates drastically) 2. We recommend 13~15dB + max gain of repeater between the donor and the server antenna as an isolation value. 3. Check antenna direction (make sure that the Donor and Server antennas are not facing one another) 4. Placing an attenuator before the nearest serving antenna can also help to increase isolation.
