MBF-40 SMR900 PS REPEATER PRODUCT DESCRIPTION AND USER’S MANUAL Cobham Wireless – Coverage Date: 31-May-18 www.cobham.com/wireless Doc. No. 00141UM Rev. 1.0 Page | VI FCC RF Exposure Limits This unit complies with FCC RF exposure limits for an uncontrolled environment. This equipment must be installed and operated with a minimum distance of 33 cm between the radiator and any person’s body. Antenna Installation Installation of an antenna must comply with the FCC RF exposure requirements. The antenna used for this booster must be mounted on a permanent structure. The FCC regulations mandate that the ERP of type B signal boosters should not exceed 5 W, this is equivalent to 8.2 W EIRP. Therefore the max antenna gain allowed for this type of signal booster should be limited to the values given by equation 1 (below) for the service antenna. Equation (1) — Max SERVICE antenna gain Maximum service antenna gain (dBi) = 39.1 – (37 dBm - # of antennas in dB – cable losses in dB). For example: No. of Antennas Cable Losses Max Allowed Antenna Gain 4 3 39.1 - (37-6-3) =11.1dBi 1 3 39.1- (37-0-3) = 5.1dbi 10 3 39.1- (37-10-3) = 15.1dbi Compliance with FCC deployment rule regarding the radiation of noise and intermodulation product Good engineering practice must be used in regard to the signal booster’s radiation of intermodulation products and noise. Thus, the gain of the signal booster should be set so that the ERP of the output of intermodulation products from the signal booster should not exceed the level of -30 dBm in 10 kHz measurement bandwidth and noise from the signal booster should not exceed the level of -43 dBm in 10 kHz measurement bandwidth. In the event that the intermodulation or noise level measured exceeds the aforementioned values, 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 MBF-900 repeater has a noise level of -43.8 dBm in 10 kHz measurement at 1 MHz spectrum outside the passband of the signal booster, worst case intermodulation products at around -14.9 dBm in a 10 kHz bandwidth and an in-band noise level at around -42.8 dBm in a 10 kHz bandwidth. Therefore, the noise or intermodulation product at the antenna input port should be calculated based on equation (2). Equation (2) — Input Noise or intermodulation product to service antenna Input Noise to service antenna: -XX dBm + Service Antenna gain – antenna splitter losses in dB – cable loss in dB Example: Intermodulation product Signal booster connected to 10 service antennas with a 100m long ½ inch cable. Losses of such a cable with the connectors = ~ 12dB Assuming 10 service antennas: antenna splitter losses = 11 dB Based on equation (2) Input antenna noise (to the antenna) = -14.9-12 -11= -37.9 dBm ERP The intermodulation product to the antenna should be -14.9 -12-11= -37.9dbm ERP
MBF-40 SMR900 PS REPEATER PRODUCT DESCRIPTION AND USER’S MANUAL Cobham Wireless – Coverage Date: 31-May-18 www.cobham.com/wireless Doc. No. 00141UM Rev. 1.0 Page | VII Example: In band Noise Signal booster connected to 10 service antennas with a 100m long ½ inch cable. Losses of such a cable with the connectors = ~ 12 dB Assuming 10 service antennas: antenna splitter losses = 11 dB Based on equation (2) Input antenna noise (to the antenna) = -42.8-12 -11=-65.8 dBm ERP The in-band input noise to the antenna should be -42.8 -12-11= -65.8dbm ERP Example: Out of band noise Signal booster connected to 10 service antennas with a 100 m long ½ inch cable. Losses of such a cable with the connectors = ~ 12 dB Assuming 10 service antennas: antenna splitter losses = 11 dB Based on equation (2) Input antenna noise (to the antenna) = -43.8 -12 -11= -66.8 dBm ERP The out of-band input noise to the antenna should be -43.8 -12-11= -66.8 dbm ERP NOTE: In this example there is a need to add an external band pass filter to attenuate the out of band noise by a further 3.2dB 1MHz away from the band edge. If fewer antennas are deployed then additional filtering will be required. 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. All Cobham Wireless repeaters include high selectivity duplexers and filters to attenuate the out of band noise. Should additional filtering be required, we have a comprehensive range of interference filters which can be supplied upon request.
MBF-40 SMR900 PS REPEATER PRODUCT DESCRIPTION AND USER’S MANUAL Cobham Wireless – Coverage Date: 31-May-18 www.cobham.com/wireless Doc. No. 00141UM Rev. 1.0 Page | VIII General Safety Warnings Concerning Use of 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 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: Safety to personnel o Before installing or replacing any of the equipment, the entire manual should be read and understood. o The user needs to supply the appropriate AC or DC power to the repeater. Incorrect power settings can damage the repeater and may cause injury to the user. o Please be aware that the equipment may, during certain conditions become very warm and can cause minor injuries if handled without any protection, such as gloves. Caution: RF Exposure o RF radiation, arising from transmitter outputs connected to AWL’s equipment, must be considered a safety hazard. o 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! o 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. o 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. Caution: Safety to equipment o When installing, replacing or using this product, observe all safety precautions during handling and operation. Failure to comply with the following general safety precautions and with specific precautions described elsewhere in this manual violates the safety standards of the design, manufacture, and intended use of this product. o Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. o Cobham Wireless assumes no liability for the customer's failure to comply with these precautions. This entire manual should be read and understood before operating or maintaining the repeater. Warning: Restricted Access Location Access to the unit installation location is restricted to service personnel who have been instructed on the restrictions and the required precautions to be taken.
MBF-40 SMR900 PS REPEATER PRODUCT DESCRIPTION AND USER’S MANUAL Cobham Wireless – Coverage Date: 31-May-18 www.cobham.com/wireless Doc. No. 00141UM Rev. 1.0 Page | IX Attention: Electrostatic Sensitivity o Observe electrostatic precautionary procedures. o ESD = Electrostatic Discharge Sensitive Device. o Static electricity can be conducted to the semiconductor chip from the centre pin of the RF input connector, and through the AC connector pins. When unpacking and otherwise handling the repeater, follow ESD precautionary procedures including use of grounded wrist straps, grounded workbench surfaces, and grounded floor mats. Caution: Class 1 Laser The repeaters described in this manual are equipped with class 1 lasers, which have been tested to meet IEC / EN 60825-1:2014 standards. Caution - Un-terminated optical receptacles may emit laser radiation. Exercise caution as follows: o Use of controls or adjustments or performances of procedures other than those specified herein may result in hazardous radiation exposure o Do not stare into beam or view with optical instruments. Optical transmitters in the fibre optic converter can send out high energy invisible laser radiation. There is a risk for permanent damage to the eye. o Always use protective cover on all cables and connectors which are not connected. o Never look directly into a Fiber cable or a connector. o Consider that a Fiber can carry transmission in both directions. o During handling of laser cables or connections, ensure that the source is switched off. o Regard all open connectors with respect and direct them in a safe direction and never towards a reflecting surface. Reflected laser radiation should be regarded as equally hazardous as direct radiation. Lifting and other Health and Safety Recommendations Certain items of Cobham Wireless equipment are heavy and care should be taken when lifting them by hand. Ensure that a suitable number of personnel, appropriate lifting apparatus and appropriate personal protective equipment is used especially when installing Equipment above ground e.g. on a mast or pole and manual handling precautions relevant to items of the weight of the equipment being worked on must be observed at all times when handling, installing or dismounting this equipment. Periodical Maintenance In order to maintain proper cooling of the RRUs, is recommended to clean the fins of the RRUs every two years using a damp cloth. If the RRU installation area is dusty or dirty, it is recommended to perform this procedure more often.

MBF-40 SMR900 PS REPEATER PRODUCT DESCRIPTION AND USER’S MANUAL Cobham Wireless – Coverage Date: 31-May-18 www.cobham.com/wireless Doc. No.: 000xxUM Rev. 1.0 Page | 1 1 INTRODUCTION MBF-40 SMR 900 repeater is an optic fed system that encapsulates solutions for single or multi-operator use. It offers seamless coverage in any indoor environment such as tunnels, subways and large buildings. Signals are coupled off from a nearby base station using an optical master unit (OMU) and then distributed via fiber to one or more MBF-40 repeaters. The MBF-40's high output power allows for greater coverage whilst deploying fewer units. Even though providing high output power, the MBF-40 uses convection cooling, subsequently increasing the repeater's MTBF. These remote units can be installed at a distance of up to 20 km from the base station site, offering great flexibility when providing RF coverage in areas where off air transmission is not a preferable solution. A distributed antenna system (DAS) can be used to distribute the signal throughout the area to be covered. Cobham Wireless can provide a complete solution including design, site surveys and equipment related to the point of interface (POI) such as combiners, filters, cross band couplers, etc. Figure 1-1. Illustration of a standard OMU II MBF Remote Application

No. 00141UM Rev. 1.0 Page | 2 1.1 Features and Capabilities • High-power indoor unit supporting SMR 900 MHz • Output power at the antenna (composite): 37 dBm • Very low noise factor — minimizes interference to BTS and increases high speed data throughput • Remote commissioning and monitoring: • Via OMU II intuitive Web GUI • SNMP v1/v2c support • Plug-and-Play — automatic detection and optical gain setting via the OMU • Automatic level control (ALC) — provides constant gain in both uplink and downlink paths according to the defined maximum output level • Backup battery for ‘last gasp’ indication (sending fault error before power failure) • Power source: 115 VAC or -48 V power (model dependent) 1.2 ALC The repeater has a constant gain in both uplink and downlink paths. The repeater has a defined maximum output level. If the input signal amplified by the gain set exceeds the set output limit, an automatic level control (ALC) loop is activated. This ALC ensures that the amplifier does not add distortion to the radio signal. Below are examples of the ALC function for one and two carriers. Figure 1-2. Example of ALC for One and Two Carriers
MBF-40 SMR900 PS REPEATER PRODUCT DESCRIPTION AND USER’S MANUAL Cobham Wireless – Coverage Date: 31-May-18 www.cobham.com/wireless Doc. No. 00141UM Rev. 1.0 Page | 3 1.3 Operating Temperature The MBF-40 is designed primarily for multi carrier purposes. If the repeater is run at full output power over a long period of time, additional, external cooling may be required; this can take the form of air-conditioning or an external fan assembly. NOTE: The repeater is equipped with a power management function that steps down the power and, if needed, fully shuts down the amplifier chains until temperature reaches normal values. 1.4 MBF-40 Management Web GUI MBF-40 is remotely commissioned and monitored via an OMUII session. Local access to the unit is not required for commissioning. Additional configuration and troubleshooting options are available via a direct connection to the MBF-40 IP address. A direct session can be opened locally or remotely. NOTE: Direct remote communication requires connecting the MBF-40 to an Ethernet network. 1.5 MBF-40 Basic Interfaces The MBF unit provides several types of interfaces: • Lock and screws for protection and security • External service antenna and GND connections • Internal connections for power, Fiber optics and alarm cables routed via openings in the front panel. • Internal USB and Ethernet connections for local setup via web GUI

Ensure good EMV protection. If insufficient Electromagnetic Protection is provided, or if EMV measures are not taken, warranties issued by Cobham Wireless are not valid. Connect the lightning protection The lightning hazard to electric and electronic equipment consists in the interferences of direct lightning current infections and high surge voltages induced by the electromagnetic field of nearby lightning channels or down conductors. Amplitudes from cloud-to-earth lightning amounts to several 10 kA and may last longer than 2 ms. The damage caused depends on the energy involved and on the sensitivity of the electronics systems. Ensure that lightning protection measures are taken to create a reliable repeater site. Protect all coaxial cables and power cables from the transients caused by lightning. Fit all cables with suitable lightning protection devices. The primary protective device is part of the site installation and is not supplied by Cobham Wireless. Coaxial lightning protection is normally one of these three types: gas capsule, high-pass and Bandpass. There also need to be a protective device installed on the power supply cord. Several lightning protection devices should be used in series with declining threshold voltages to help attenuate the pulse component which makes it through the first layer of protection. Figure 2-1.

No. 00141UM Rev. 1.0 Page | 11 For detailed information please refer to IEC 61024-1 and 61312-1 for international standards for protection of information systems against LEMP (Lightning Electromagnetic Pulse), including radio transmitters. They define proper planning, installation and inspection of effective lightning protection systems. Cobham Wireless repeaters comply with the EN standard ETS 301 498-8 which stipulates demands on lightning/surge protection for typical infrastructure telecom equipment installations. 2.2.6 External Alarm and Relay Considerations For installations that include connections of external alarms and relays • The connector plinth for the external alarms is located inside the repeater. • The strain relief fitting in is a Pg 13.5 suitable for a 6-12 mm cable diameter. • Four external alarm sources can be connected to the repeater. • Alarm operating voltage: between 12 and 24 VDC. • The relay supplies 100mA maximum current 2.2.7 Location Criteria Location criteria • For wall mount installations: • Wall compatibility - check the suitability of the wall on which the unit is to be to be fitted. • Plan mount - check the actual fixing centers (see below) and overall dimensions of the unit enclosure. The unit is supplied with two wall mounting brackets; when the unit is mounted on these brackets adequate ventilation is provided between the unit and the wall to which it is fixed. • Plan connection cable clearances — the optical, RF and power connections located on the underside of the unit will need at least 300 mm vertical clearance below the unit to enable the connections to be made. The minimum bend radius for optical and RF cables must not be less than the recommendations made by the cable manufacturer. Plan the cable runs and ensure adequate space is available. • Allow for door opening — ensure that there is sufficient space at the front of the unit to allow the door to be fully opened and for maintenance engineers to get access to the unit with test equipment such as a spectrum analyzer. Allow an additional 500 mm of space in front of the unit when the door is fully open. • Allow for heat dispersion — mount the repeater so that heat can be dispersed from it. The repeater wall mounting kit ensures an optimum airflow between the wall and the repeater.) Do not block this air channel as it will cause the MTBF of the repeater to drop dramatically, or even in the worst case cause the repeater to fail completely.

No. 00141UM Rev. 1.0 Page | 39 3.3.4 Integration into the AEM NOTE: Integration into the AEM is only performed from the AEM side – no action is required from the MBF-40 side. The AEM automatically connects to the repeater and downloads all the repeater information. The AEM then configures the repeater with the IP address where alarms and reports should be sent to, and optionally with a secondary IP address where the repeater can connect to in case connection to primary IP fails. When heartbeat reports and alarms are sent from the repeater to the AEM also the latest information about the status and RF-configuration is included. This means that the AEM operator always has information about the current status in the AEM database (and does not need to call the repeater to find this out). NOTE: Once the repeater is integrated to the AEM, all changes to the repeater should preferably be done from the Element Manager in order to ensure that the database always contains correct information. 3.3.5 What Next? The MBF-40 unit is now ready for operation. You may monitor the unit's general status via the OMU II Main window and if the node is faulty (red LED), access the dedicated configuration screen in Basic or Advanced view for more information. NOTE: Consult the OMU II user manual for additional information on RF and optical adjustments.

If in the unlikely event of any unit failure, the faulty repeater should be replaced. A failed unit can be removed and replaced with a spare while the rest of the system (other repeaters) is still operating. However, the power supply of the failed repeater should be isolated from the power before anything is replaced. • In the event of a malfunction in the system, the status of the antenna systems as well as the continuity of the cabling should be checked before replacing any modules within the repeater. • The input / output RF level power level monitoring windows are for indication only and should not be considered a replacement for laboratory test equipment accuracy of measurement of actual signal levels. The error of measurement will be high at low input levels. • The normal operating range of signal measurement is as follows: • Downlink Output range +20 dBm to +43 dBm • Uplink Output range -10 dBm to +5 dBm • In the event of a failure Cobham Wireless’s support service should be contacted for advice on a possible module replacement or other action to be taken. • If a shipment of a repeater back to Cobham Wireless is made within the period of guarantee the original packing must be used. • Component Replacement - None of the modules in the repeater can be replaced without removing the repeater from its mounting and opening the cover of the repeater. • Product Disposal - Disposal of this product must be handled according to all national laws and regulations. For detailed information regarding materials, please refer to Cobham Wireless. CAUTION! Please be aware that the equipment may, during certain conditions become very warm and can cause minor injuries if handled without any protection, such as gloves. 6.2 Batteries The Repeater contains two types of batteries: • A battery pack in the power supply unit, consisting of 8X NiMh batteries. • A button cell CR1216 on the controller board. CAUTION! o Please be aware that the equipment may, during certain conditions become very warm and can cause minor injuries if handled without any protection, such as gloves. o Risk of explosion if battery is replaced by an incorrect type. Dispose of used batteries according to local laws and instructions.

Tools Tool Description Illustration Fiberscope connected to a PC running the appropriate viewing software. It is highly recommended that some form of Fiber viewing equipment such as a Fiberscope is used to ensure that all Fiber connections are clean before termination; failure to do so could result in poor system performance Lint-free swabs (box), Cobham Wireless P/N 99-000127 Lint-free wipes (pack) Cobham Wireless P/N 99-000125 Fujikura “One Click” cleaner Cobham Wireless P/N 98-900004. 99% isopropyl alcohol (can), Cobham Wireless P/N 99-000126 Cletop type S Cassette Cleaner, Cobham Wireless P/N 98-900001

No. 00141UM Rev. 1.0 Page | 63 Dry F/O Cleaning Procedure: WARNING! Invisible laser radiation might be emitted from disconnected Fibers or connectors. Do not stare into beams or view directly with optical instruments. 1. Before cleaning the optical connectors on the OMU it is advisable to clean the connector of the mating cable being attached to the optical port. An unclean optical connector is often the cause for reduced system performance. A bit of dust or oil from a finger can easily interfere with, or block light. Fortunately, it is very easy to clean the connector. Be sure to use the correct procedure for the given connector. When disconnected, cap the SC/APC connector to keep it clean and prevent scratching the tip of the ferrule. Use a product specially designed for the purpose, such as the Cletop type S Cassette Cleaner. 2. Begin by dry cleaning the F/O bulkhead connector (shown below is the Fujikura One-Click in use). IMPORTANT! Always make sure there is a way of inspecting the connector after cleaning. Cleaning can actually leave the end-face in a worse condition, since alcohol residue is one of the most difficult contaminants to remove. 3. Remove the protective cap from the cleaning-head end of the “One Click” cleaner, lift the protective end-cap on the Fiber connector and offer-up the end to the Fiber connector

With the cleaning-head end fully engaged in the connector, push until an audible “click” is heard 5. Without fully withdrawing the cleaning head end push it in again twice more, each time until an audible “click” is heard. 6. Withdraw the “One Click” cleaner and replace the protective end cap. 7. Inspect the Fiber connector using a Fiberscope. On the PC monitor, verify that there is no contamination present on the connector end-face. 8. If the connector is dirty, clean it with a wet cleaning technique followed immediately by dry cleaning. This is to remove any remaining residue from the wet clean (the following steps demonstrate a wet cleaning technique). Wet F/O Cleaning Procedure ATTENTION! Invisible laser radiation might be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. 1. Lightly moisten a new lint-free wipe with 99% isopropyl alcohol (Step 1 below). Tip: Have a dry lint-free swab available for immediately drying after performing the wet-cleaning. 2. Lightly press and turn a clean lint-free swab in the moistened area of the wipe to moisten the swab. It is important that the swab is not too wet (Step 2 below). 3. Insert the moistened lint-free swab into the bulkhead adapter. Lightly press and rotate several times in the same direction (Step 3 below). Figure 6-1. Wet-Cleaning Technique 4. Immediately use a dry lint-free swab to clear any remaining alcohol residue. NOTE: Do not re-use any of the wipes and/or swabs. Dispose of them properly. 5. Follow steps 3 to 6 of dry cleaning above 6. Re-inspect the Fiber using the Fiberscope. On the computer monitor, verify that there is no contamination present on the connector end-face. 7. If the fibre is still dirty, go back to step 1 (wet cleaning) and repeat the entire process. NOTE: The entire wet/dry cleaning cycle should only be used twice, if the fiber is still dirty after two cycles of wet/dry cleaning seek advice from the Cobham Wireless Support Desk.
