Axell D-SBR 3709S Repeater PRODUCT DESCRIPTION AND USER’S MANUAL IV Doc PN 00038UMCD Rev. 1.6 © Axell Wireless Ltd Compliance with FCC WARNING: This is NOT a CONSUMER device. This device designed for installation by FCC LICENCEES and QUALIFIED INSTALLERS. You must have an FCC LICENCE or express consent of an FCC Licensee to operate this device. This is a Class B signal booster. You MUST register Class B signal boosters (as defined in 47 CFR 90.219) online at www.fcc.gov/signal-boosters/registration. Unauthorized use may result in significant forfeiture penalties, including penalties in excess of $100,000 for each continuing violation. The installation procedure must result in the signal booster complying with FCC requirements 90.219(d). In order to meet FCC requirements 90.219(d), it may be necessary for the installer to reduce the UL and/or DL output power for certain installations. FCC Part 15 This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: 1. This device may not cause harmful interference. 2. This device must accept any interference received, including interference that may cause undesired operation. If not installed and used in accordance with the instructions, this equipment generates, uses and can radiate radio frequency energy. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to RF reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • Reorient or relocate the Donor antenna. • Increase the separation between the equipment and receiver. • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Unauthorized Changes to Equipment Changes or Modifications not expressly approved by the manufacturer responsible for compliance could void the user’s authority to operate the equipment. Only for in-building applications One must be aware that FCC regulation mandate that this repeater is to be used only for in-building applications and thus feed passive or active DAS (Distributed Antenna Systems) accordingly. FCC RF Exposure Limits This unit complies with FCC RF exposure limits for an uncontrolled environment. All antennas must be operated at a minimum distance of 35 cm between the radiator and any person’s body.
Axell D-SBR 3709S Repeater PRODUCT DESCRIPTION AND USER’S MANUAL © Axell Wireless Ltd Doc PN 00038UMCD Rev. 1.6 V Antenna Installation Installation of an antenna must comply with the FCC RF exposure requirements. The antenna used for this transmitter must be mounted on permanent structures. The FCC regulation mandates that the EIRP of type B signal boosters should not exceed 5W. Therefore the max antenna gain allowed for this type of signal booster should be limited to the values given by equation (1) for the service antenna and equation (2) for the donor antenna Equation (1) - Max SERVICE antenna gain Max SERVICE antenna gain (dBi) = 37 – (33dBi - # of antennas in dBi – cable losses in dBi). For example: No. of Antennas Cable Losses Max Allowed Antenna Gain 4 3 37 - (33-6-3) = 13dBi 1 3 37- (33-3) = 7dBi 10 3 37- (33-10-3) = 17dBi Equation (2) - Max DONOR antenna gain Max antenna gain (dBi) = 37 – (27dBi - cable losses in dBi). Compliance with FCC deployment rule regarding the radiation of noise Good engineering practice must be used in regard to the signal booster’s noise radiation. Thus, the gain of the signal booster should be set so that the EIRP of the output noise from the signal booster should not exceed the level of -43 dBm in 10 kHz measurement bandwidth. In the event that the noise level measured exceeds the aforementioned value, the signal booster gain should be decreased accordingly. In general, the ERP of noise on a spectrum more than 1 MHz outside of the pass band should not exceed -70 dBm in a 10 kHz measurement bandwidth. The 3709 signal booster has a noise level of -50 dBm in 10 kHz measurement at 1 MHz spectrum outside the passband of the signal booster and an in-band noise level at around -34 dBm in a 10 kHz bandwidth. Therefore, the noise at the antenna input port should be calculated based on equation (3). Equation (3) - Input Noise to SERVICE antenna Input Noise to service antenna: -43 dBm + Service Antenna gain – Antenna splitter losses in dBi – cable loss in dB Example: Signal booster connected to 10 service antennas with a 100m long ½ inch cable. • Losses of such a cable with the connectors = ~ 11dB • Gain = ~ 2 dBi Assuming 10 service antennas: antenna splitter losses = 11 dB Based on equation (3) Input antenna noise (to the antenna) = -51.1+2-11-11=-71.1 dBm The inband input noise to the antenna should be -32+2 -11-11= -52 dbm
Axell D-SBR 3709S Repeater PRODUCT DESCRIPTION AND USER’S MANUAL VI Doc PN 00038UMCD Rev. 1.6 © Axell Wireless Ltd NOTE: In this example there is no need to add an external bandpass filter to attenuate the out band noise. Conclusion: Good engineering practice requires that in general when the out of band noise measured at the service antenna input is more than -70 dbm per 10 kHz measurement bandwidth, an external band pass filter should be added to attenuate the out of band noise level. General Safety Warnings Concerning Use of This System Always observe standard safety precautions during installation, operation and maintenance of this product. Caution labels! Throughout this manual, there are "Caution" warnings. "Caution" calls attention to a procedure or practice, which, if ignored, may result in injury or damage to the system, system component or even the user. Do not perform any procedure preceded by a "Caution" until the described conditions are fully understood and met. Danger: Electrical Shock This equipment must be installed only indoors. To prevent electrical shock when installing or modifying the system power wiring, disconnect the wiring at the power source before working with un insulated wires or terminals. Caution: RF Exposure RF radiation, arising from transmitter outputs connected to AWL’s equipment, must be considered a safety hazard. This condition might only occur in the event of cable disconnection, or because a ‘spare’ output has been left un-terminated. Either of these conditions would impair the system’s efficiency. No investigation should be carried out until all RF power sources have been removed. This would always be a wise precaution, despite the severe mismatch between the impedance of an N type connector at 50 ohm, and that of free space at 377 ohm, which would severely compromise the efficient radiation of RF power. Radio frequency burns could also be a hazard, if any RF power carrying components were to be carelessly touched! Antenna positions should be chosen to comply with requirements (both local & statutory) regarding exposure of personnel to RF radiation. When connected to an antenna, the unit is capable of producing RF field strengths, which may exceed guideline safe values especially if used with antennas having appreciable gain. In this regard the use of directional antennas with backscreens and a strict site rule that personnel must remain behind the screen while the RF power is on, is strongly recommended. Where the equipment is used near power lines or in association with temporary masts not having lightning protection, the use of a safety earth connected to the case-earthing bolt is strongly advised.

Axell D-SBR 3709S Repeater PRODUCT DESCRIPTION AND USER’S MANUAL © Axell Wireless Ltd Doc PN 00038UMCD Rev. 1.6 1 11 IInnttrroodduuccttiioonn This manual describes the Axell D-SBR 3709S IP65 High Power Digital Channel/Band Selective Repeater. The repeater is designed for indoor installations and includes advanced filtering capabilities to support the SMR 900MHz band for public safety and commercial operations. The D-SBR 3709S repeater supports up to eight non-contiguous sub-bands/channels, where the gain and output power of each sub-band is independently tunable across the entire band. This provides an optimal solution for operators that have a non-contiguous spectrum. The system supports advanced Digital Signal Processing (DSP) technology, programmable digital filters. These capabilities enable the user to quickly and simply customize the Repeater according to changing site requirements. Highly linear MCPA components and unparallel innovative DSP filtering provide top level performance that support high throughput of the latest modulation technologies such as HSPA and LTE. The Smart-ALC power control algorithm automatically optimizes the gain setting by learning the actual range of RSSI levels over a user-specified period of time. The Smart-ALC algorithm prevents oscillations, reduces the amount of isolation required by the system and optimizes the system to minimize noise rise at the donor cell site. Intuitive Web access monitoring and management GUI is accessible via a local or remote Ethernet connection. Figure 1-1. Axell D-SBR 3709S Repeater

Perform this procedure before connecting the antennas to the Repeater or powering on the Repeater. The Repeater should not be operated prior to the verification of the operating parameter in its installation environment. Before connecting the antennas or power, verify isolation between the donor and mobile antennas The isolation between the Base/Donor and Mobile/Service antennas is critical. • For proper operation of the Repeater, it is recommended that the isolation between the Donor and Service antennas be at least 12dB higher than the Repeaters set gain. • Insure proper vertical or horizontal distance separation between Donor and Service antennas NOTE: Lower isolation can lead to high in-band ripple, oscillations and low signal quality. To measure the isolation, proceed as follows: 1. Inject a known signal from a signal generator into one antenna (preferably the Donor antenna). 2. Measure the coupled output from the Service antenna, using the Spectrum analyzer and LNA if applicable. 3. Perform this procedure across the frequency range of both the Uplink and Downlink bands. 4. Register the lower result for system operation. 33..77 VVeerriiffyyiinngg tthhee LLiinnkk bbeettwweeeenn tthhee BBTTSS aanndd tthhee RReeppeeaatteerr This test checks the signal strength from the BTS antenna to the Repeater. Proceed as follows: 1. Using a Spectrum analyzer, measure the received signal from BTS at the Donor antenna port near the Repeater. 2. Adjust the Donor antenna direction to receive the maximum signal strength. 3. Compare the received signal strength with the calculated signal strength from the design phase. 4. In case of discrepancy, check for one of the following: • Antenna out of direction • Antenna tuned to side lobe instead of main lobe • Antenna connector or antenna cable faulty • Line-of-sight problem (obstruction), etc. • Register the signal strength of the downlink channel for the system operation phase.

Blinking Orange/red User mute System mute - Due to isolation problem or temperature Check gain of the repeater, if gain is minimum, then it is an isolation problem -> improve isolation. Turn OFF the Repeater (resets the function), and turn it ON again. If the fault resumes, replace the unit. READY LED
Axell D-SBR 3709S Repeater PRODUCT DESCRIPTION AND USER’S MANUAL © Axell Wireless Ltd Doc PN 00038UMCD Rev. 1.6 39 6.1.2 Internal LEDs Two LEDs (UL and DL) located inside the repeater provide an indication on the UL and DL signals. The following figures show an example of the LED locations (the location may differ on your unit). Figure 6-2. Axell D-SBR 3709S Internal View The following table provides a description of the UL and DL LED troubleshooting procedures. Color Status and Probable Cause Recommendation Green Normal operation - Red Major error The Repeater must be replaced Blinking Green Low input signal from Donor/Mobile antenna Check the Donor antenna input power Orange High out of band signal input power from Donor/Mobile antenna Redirect donor azimuth or add attenuator before base port. Caution! Disconnect power to the repeater before connecting the attenuator. Once installed, reconnect power. Blinking Orange/red User mute System mute - Due to isolation problem or temperature Check gain of repeater. If gain is minimum, then it is likely an isolation problem -> improve the isolation. Reset the Repeater by turning if off and on again. If the fault continues, replace the unit. DL UL LEDs

Axell D-SBR 3709S Repeater PRODUCT DESCRIPTION AND USER’S MANUAL © Axell Wireless Ltd Doc PN 00038UMCD Rev. 1.6 41 Alarm Fault and most probable cause Recommendation System Mute Cause: Repeater amplification is muted (automatically). ----- User Mute Cause: Repeater amplification is muted (manually) as a result of an operator action. ----- Built In Test Cause: Self test. ----- Temperature Fault: High temperature. Most probable cause: Unit temperature becomes high. Excessive heat. Corrective action: Check the Repeater case for external causes (sun, hot environment, air flow is blocked). Eliminate the reason for excessive heat. Donor Power too Low The signal from the Donor antenna is too low. Check connections and antenna position. PAmp Current Fault: the Pre Amplifier current exceeds the allowed limits. Fault in the DL or UL path. Most probable cause: Downlink (Uplink) power amplifier module outputs a low current. Corrective action: Check the LEDs in the Repeater (see 6.1). RSSI Fault: Fault in the DL or UL path Most probable cause: Excessively high input signal Corrective action: Check the LEDs in the Repeater (see 6.1). VSWR Fault: The return loss of the Downlink antenna or cable connection exceeds 6 dB (VSWR 3:1). Most probable cause: This alarm provides an indication of the status of the cable connected to the antenna. If a cable is defective, the VSWR is decreased and the alarm is triggered again. Corrective action: Check cable connected to the antenna. Reduced Gain by IMOP Description: Shows when the iMOP mechanism was activated in order to respond to detected oscillations. GREEN – normal operation – no oscillations were detected. RED – oscillations were detected and the system reduced gain in order to eliminate the oscillations. Corrective action: Check the Donor and Mobile antenna installations for isolation. After isolation is within the required levels, the system will automatically increase gain (since it will no longer affect oscillations) and the LED will turn GREEN. Interferer Power Exceeded Indicates if there is any external interference at a level that may affect the operation of the unit. Green – low or no interference. Unit operation is not affected. Red – high external interference that may affect the operation of the unit. It is recommended to identify the source of the interference and distance the source or the unit from each other.
