2 Introduction ID No: 161692 PRELIMINARY Page 11 2 INTRODUCTION 2.1 PURPOSE Wireless communication systems provide a two-way information transfer (voice and data) between a base station and multiple mobiles within a given area. Environmental variables such as physical structures both man-made (buildings) and natural (mountains) attenuate signals in the transmission path, which reduce the transport signal’s strength. This attenuation leads to a reduction in quality and data rate and eventually prohibits the system’s use entirely. A Node C is specifically designed to extend coverage, enhance quality, and increase air-interface capacity. In the downlink (DL), the Node C picks up signals coming from the base station, filters them, amplifies them, and retransmits them to the mobile. In the uplink (UL), it picks up signals from the mobile, filters them, amplifies them, and retransmits them to the base station. The Node C constantly monitors the quality of the signals passing through it, while simultaneously electronically decreasing isolation requirements. 2.2 THE NODE C NETWORK ELEMENT The Node C is a primary network element, capable of enhancing up to three adjacent CDMA carriers in a CDMA system. Its primary function is to increase the signal strength between multiple mobiles and a base station in areas where basic voice or high-speed data transmission is not available. It may be used for basic coverage, signal reinforcement, and cell shaping, which can increase a network’s coverage area, data rate, and capacity. The Node C is a dedicated CDMA device. However, several enhancers operating at different frequencies and technologies may share the same hardware (cables and antennas) via a crossband coupler. Within the CDMA frequency band, multiple operators may use the same unit via additional modules, thus reducing cost, while sharing the user interface and antennas. The Node C may be set-up locally or remotely. A circuit switch or packet data modem may be connected to an integrated controller. This provides the network management system with on-demand, alarm generated, or heartbeat monitoring via the always-connected packet features. The Node C has features and functions that may be monitored and changed by the operators via a web-based browser remotely or locally, or via the SNMP based OMC software platform. The graphical interface of the Node C provides a setup menu including a setup wizard which allows both setup and monitoring capability without any equipment required apart from a laptop or PC. The Node C network element is self-diagnosing, self-adaptive, and virtually maintenance-free.

3 Installation ID No: 161692 PRELIMINARY Page 13 3 INSTALLATION 3.1 MECHANICAL INSTALLATION 3.1.1 General Read the health and safety warnings in chapter 1.2 Health and Safety Warnings. 1. Do not install the unit in a way or at a place where the specifications outlined in the Environmental and Safety Specifications leaflet of the manufacturer are not met. 2. It is recommended only to use the mounting hardware delivered by the manufacturer. If different mounting hardware is used, the specifications for stationary use of the unit must not be exceeded. ) Note: Exceeding the specified load limits may cause the loss of warranty. 3. The unit is considerably heavy. Make sure that a suitable mounting surface is used. Ensure there is adequate manpower to handle the weight of the system. 4. Due to power dissipation, the unit may reach a very high temperature. Ensure sufficient airflow for ventilation. Above and below the units a minimum distance of 300* mm to ceiling, floor, etc. has to be kept. This distance must also be observed between two units if they are mounted one above the other. * This value does not apply to the distance between Interface Unit and Node C. The distance required between the two cabinets is specified in table 3-1 Mounting distance. If any different or additional mounting material is used, ensure that the mounting remains as safe as the mounting designed by the manufacturer. Ensure that the static and dynamic strengths are adequate for the environmental conditions of the site. The mounting itself must not vibrate, swing or move in any way that might cause damage to the unit. ) Note: Both the Node C and the Interface Unit are delivered with a pre-mounted front cover. This cover is of vital importance for the correct forced airflow (of Node C 43) and for passive cooling (of Node C 37 and Interface Unit). Thus, do not operate the units without cover.
User’s Manual for Node C Network Elements Page 14 M0121A1A_uc.doc 3.1.2 Wall Mounting Procedure • Check the wall mounting kit and the wall to determine their suitability. • The maximum distance between the Node C and the Interface Unit depends on the length of the cable bridge (standard length is 500 mm) by which they will be connected (see table 3-1 Mounting distance). Thus, before marking the mounting positions, check the length of the cable bridge and make sure to install the units at a suitable distance. Mounting style: beside each other* one above the other** Length of cable bridge: 500 mm 800 mm 2000 mm only 2000 mm possible Maximum distance 140 mm 400 mm 1600 mm 1000 mm (min.=300 mm)* Maximum distance is referring to distance between the cabinet sides ** It is recommended to install the Node C above the Interface Unit; max. distance is the distance between top of lower and bottom of upper unit table 3-1 Mounting distance ) Note: The following figures show units that are mounted beside each other. To install one above the other proceed in the same way, also observing the specified mounting distance from table 3-1. • Mark the position of the eight drilling holes (four per unit) for the Node C and Interface Unit according to figure 3-1.

This unit contains dangerous voltages. Loss of life, severe personal injury or property damage can be the result if the instructions contained in this manual are not followed. 2. It is compulsory to ground the unit before connecting power supply. A grounding bolt is provided on the cabinet to connect the ground bonding cable. 3. Although the unit is internally protected against overvoltage, it is strongly recommended to earth the antenna cables close to the unit’s antenna connectors for protection against atmospheric discharge. In areas with strong lightning it is strongly recommended to insert additional lightning protection. 4. Hard wired installation of mains supply for the unit requires an easily accessible separation device in the mains circuit. 5. Make sure that an appropriate circuit breaker and an overcurrent limiting device are connected between mains and the unit. 6. A connection of mains supply to a power socket requires the power socket to be nearby the unit. 7. The unit might be supplied from IT mains. (The maximum nominal line to line voltage must not exceed 400VAC). 8. Incorrectly wired connections can destroy electrical and electronic components. 9. To avoid corrosion at the connectors caused by electrochemical processes, the material of the cable connectors must not cause a higher potential difference than 0.6V (see electrochemical contact series). 10. It is sufficient to tighten the 7/16 or N antenna connector hand-screwed. Any use of a tool (e.g. pair of pliers) might cause damage to the connector and thus lead to malfunctioning of the unit. 11. For unstabilized electric networks which frequently generate spikes, it is advised to use a voltage limiting device. 12. The unit complies with the surge requirement according to EN 61000-4-5 (fine protection), however, it is recommended to install an additional medium (via local supply connection) and/or coarse protection (external surge protection) depending on the individual application in order to avoid damage caused by overcurrent. 13. Observe the labels on the front panels before connecting any cables.

All connectors are located at the bottom of the cabinet. An operator should refer to the documentation of the cable connector manufacturer for best mating procedures. Furthermore, the bending radius of the antenna cables should be maintained at all times. There are several issues to be considered when selecting the cable and antenna types. • Smaller diameter cables are less expensive and easier to install but have worse performance. • Highly directional antennas with good front-back-ratios (40 dB is typical) are recommended because they improve isolation and cell site selectivity. Tighten the 7/16 or N connectors ONLY by hand. The use of pliers may cause damage to the connector and impair the performance of the Node C. figure 3-12 Front view of antenna connections 3.2.5 Connection of Cable Bridge The Interface Unit and the Node C are connected via a cable bridge.

The antenna connectors may be terminated by connecting them to their respective antennas or to a dummy load. • Only qualified personnel should carry out the electrical, mechanical, commissioning, and maintenance activities that require the unit to be powered on when open. • When opening the Node C or interface box do not damage the warranty labels on the internal devices. The warranty is void if the seals are broken. To open the cabinet of the Interface Unit, first remove the front cover plate by loosening the four M5 socket head cap screws (circle-marked in figure to the left). Do not remove those screws. When they are loosened, the front cover plate can be taken off. To open the housing, unscrew the three M5 socket head cap screws (captive) of the top cover of the Interface Unit. ) Note: Do not forget to reinstall the front cover afterwards to ensure safe operation. ) Note: Before closing the Interface Unit, make sure that the mains power switch inside is set to On: figure 4-1 Front and top cover screws figure 4-2 Position of mains power switch Three top cover screws Mains power switch

Select ‘Setup Wizard‘ from the main page. 2. Select ‘Antenna Alignment Assistant‘. 3. Select the desired 5 MHz channel by using the dropdown box. 4. Select ‘Start Alignment’. 5. Observe the Rx DL Power and Pilot RSCP measurements and orient the antenna to maximize performance. 6. Click ‘Home’ when completed.
User’s Manual for Node C Network Elements Page 62 M0121A1A_uc.doc b) Typical Tuning Procedure (See example table below): 1. Point the donor antenna in the general direction of the donor base station. 2. Start the AAA. 3. Verify that the reported DL Rx Power is above –90dBm. If not, orient the antenna until the signal is above –90dBm. 4. Wait for Pilot RSCP results to be reported (indicating that a valid pilot has been found). 5. Verify that the ARFCN and frequency reported at the top of the table matches the ARFCN and frequency of the donor base station. 6. Orient the antenna to maximize the Pilot RSCP from the donor base station. Usually, the best method is to course-tune the antenna based on DL Rx Power measurements and then fine-tune based on Pilot RSCP measurements. However, if multiple pilots are present, then using the DL Rx Power measurements alone may not work well, and the user will have to rely on Pilot RSCP only. 7. If multiple rays are present, then it is usually best to orient the antenna to maximize the level of the first ray (the line-of-sight – or LOS – signal). However, if the first ray is not the strongest signal, then there is an obstruction in the LOS signal, and the strongest signal is a multipath component. This may mean that the donor signal is prone to fluctuation, resulting in sub-optimal performance of the unit.

4 Commissioning ID No: 161692 PRELIMINARY Page 63 c) Notes on the AAA Measurement Results: 1. The DL RX Power is the total power in the selected 5 MHz channel. The DL Rx Power measurement is updated approximately once per second. 2. The Pilot Received Signal Code Power (RSCP) measurements are updated approximately once every four seconds after the antenna assistant finds a valid pilot channel within the selected 5MHz bandwidth. It may take up to one minute to perform the initial scan and report Pilot RSCP results. 3. The most recent results are displayed in the first row, and previous results move down one row in the table. 4. Data is columnized based on the most recent pilot measurement results. 5. The pilot measurements display up to the four strongest rays. The measurement result could show one pilot with four rays, two pilots with two rays each, one pilot with three rays and one pilot with one ray, or four pilots with one ray each (or fewest results if no additional pilots are found). 6. Multiple rays of the same pilot will be shown if the weaker rays are within 10dB of the strongest ray. 7. The Pilot RSCP data is sorted based on the total power of all multipaths for each particular scramble code. For instance, if one pilot has two rays, each at –63dBm (for a total power of -60 dBm), they will be listed first if all other pilots are less than -60 dBm. 8. If two or more multipath signals are received, then the power of each ray will be displayed in order of arrival. The first ray is the line of sight signal and should be the strongest. However, it is possible for the later rays to be stronger. 4.2.4.2 Connectivity and Upload This page serves to upload new software (press the Upload Software button and follow the instructions) and for entering the modem settings for OMC communication. figure 4-6 Connectivity and Upload menu

User’s Manual for Node C Network Elements Page 70 M0121A1A_uc.doc The following figure shows the RF block diagram of the Node C. figure 5-2 Configuration of a Node C network element The Node C is designed to amplify signals between multiple mobiles and a base station in a CDMA system. The unit consists of a filter and amplifier chain in the downlink and one or two filters and amplifier chains in the uplink (primary and diversity). The uplink and downlink paths are connected via a duplexer on both ends of each path.
5 Functional Description ID No: 161692 PRELIMINARY Page 71 In the primary uplink path, a signal originating from the mobile is separated from the downlink signal via the primary UL IN duplexer. It is then amplified by an integrated low noise amplifier (LNA) and forwarded to the uplink digital channel module (DCM). The DCM down-converts the signal to base-band, digitally filters it, amplifies it and then up-converts it. In addition the interference cancellation technology is implemented in the DCM. Finally, the signal is sent to the final amplifier and combined with the downlink input signal in the DL IN duplexer. The optional diversity uplink path (via a second filter) is identical except signals enter via the diversity UL IN duplexer and are combined in the DCM with the primary path. In the downlink path, a signal originating from the base station is separated from the uplink signal in the DL IN duplexer. It is then amplified by an integrated low noise amplifier (LNA) and forwarded to the downlink digital channel module (DCM). The DCM down-converts the signal to base-band, digitally filters it amplifies it and then up-converts it. In addition the interference cancellation technology is implemented in the DCM. Finally, the signal is sent to the final amplifier and combined with the uplink input signal in the primary UL IN duplexer. The downlink DCM is also responsible for communication and control of the entire unit. Using a Node C 1943 as an example, the following figure illustrates the positions of the RF components inside the Node C. figure 5-3 RF path of a Node C, exemplary
User’s Manual for Node C Network Elements Page 72 M0121A1A_uc.doc 5.2 FEATURES OF THE NODE C 5.2.1 Filters Filters are set automatically according to the channels set in “Setup Wizard” or “Technician Setup”. For further information about these menus refer to chapters 4.2.4.1 and 4.2.4.3. Possible filters are: 5 10 15 5 5 5 MHz and , , One WCDMA channel two adjacent WCDMA channels three adjacent WCDMA channels two WCDMA channels; intermediate channel not used 5.2.2 Digital ICE (Digital Interference Cancellation Equipment) Digital ICE has been developed to enhance antenna isolation. This feature enables the Node C to provide coverage in areas where effectivity is decreased due to physical site limitations which cause insufficient antenna isolation. Antenna isolation is the RF loss measured between the donor antenna and the coverage antenna. If the gain of the network element exceeds the path loss, feedback in form of oscillation occurs. The isolation is usually dominated by the direct path loss from one antenna to the other, but reflections can contribute to or even affect antenna isolation. Digital ICE cancels the signal from the primary feedback path, thus allowing the gain of the network element to be increased. The required delay resulting from the on-site conditions is measured by the DCM module and set accordingly. For software setting commands please refer to the online help screens. The Digital ICE function can be enabled or disabled in the “Technician Setup” page (see chapter 4.2.4.3). Isolation and gain margin* can be checked in the “Status and Reports” menu accessible via the home page of the web interface (see figure 4-4). * gain margin = antenna isolation minus Node C gain
5 Functional Description ID No: 161692 PRELIMINARY Page 73 5.2.3 VSWR (Voltage Standing Wave Ratio) This feature enables the provider to query the status of the antenna system (antenna & cable). The voltage standing wave ratio of the DL output antenna port is measured. If the VSWR falls below the value set in the “Alarming Management” (see chapter 4.2.4.4), an alarm is released. The alarm can be forwarded to the OMC where the faults and irregularities can be acknowledged and eliminated promptly. The current VSWR value can be checked in the “Status and Reports” menu accessible via the home page of the web interface (see figure 4-4). 5.2.4 RSSI (Receive Signal Strength Indication) The RSSI provides controlling and monitoring of the receive level of a base station (DL RSSI) or user equipment (UL RSSI) to a Node C. It measures the level of the input signal by detecting the RF and converting the analogue level into a digital value. The data are processed and evaluated by software. An alarm will be released if the measured signal level exceeds the alarm level set by the provider via software. ) Note: If the Node C is equipped with a diversity path, both values will be combined before the RSSI evaluation. Thus, only one UL value is reported. The current RSSI values can be checked in the “Status and Reports” menu accessible via the home page of the web interface (see figure 4-4). 5.2.5 Alarmforwarding Alarms can be forwarded to a defined phone number or to the OMC if the Node C is equipped with a modem or a mobile station. This enables the provider to control and to query the status of the network. Faults and irregularities can be recognized and eliminated. With an optional modem the Node C also provides an SMS feature, by which the unit is able to send out alarm messages as SMS. For further details please contact your supplier.
User’s Manual for Node C Network Elements Page 74 M0121A1A_uc.doc 5.2.6 External Alarms The external alarms are used to monitor the status of one or more external devices via the Node C. A UPS or entry alarm is among the items that might be connected to the contact relay and monitored via the Node C. The cage clamp connectors are located on the distribution & alarm board of the Interface Unit. Observe that the cross-sectional area of the wires to be connected must be in the range from 0.5 - 1.0 mm2.

5 Functional Description ID No: 161692 PRELIMINARY Page 79 5.3.3 Digital Channel Module (DCM) The task of the digital channel module (DCM) is to filter and amplify any signals passing through it. In addition it takes measurements of the input and output signals and decodes the air interface to ensure proper setup and operation. Finally it performs the interference cancellation algorithms, which eliminate the normal problems associated with isolation, and has an integrated controller (in the DL part) for the entire Node C, which maintains a web server for local and remote communication. This process is accomplished by both analogue and digital means. In case the diversity option is equipped, the module receives signals from both the primary duplexer and diversity filter. Both signals are combined digitally and filtered before being amplified in the uplink amplifier. The DCM consists of an UL and DL part. figure 5-10 DCM (UL or DL part)

5 Functional Description ID No: 161692 PRELIMINARY Page 85 5.4.1.3 Battery Backup In case power fails, a battery backup system for controller and modem has been implemented. This provides enough power for the controller that is integrated into the downlink DCM and the modem to operate for a limited period of time (see chapter 7.2.3 Specifications for Optional Equipment for battery backup time). Within this time, the Node C will initiate a call to the OMC and alert the operator that power has been lost. All other functions will cease to work in case of power failure. The battery packs are protected from deep discharge by use of a low voltage disconnect unit. When performing preventive maintenance, make sure that all circuits are voltage free by disconnecting the battery cable (C1) from its connector (C2). In case of a power cycle, it is sufficient to press the “Battery disconnect button” to interrupt the voltage supply. After mains is connected again, the battery will be charged and the battery backup function will be activated automatically. figure 5-17 Battery backup module, exemplary The battery charge module is plugged directly onto the distribution & alarm board of the Interface Unit through connector C3. The battery pack should be discharged at regular intervals of about three months to optimize its service life. This service discharge may be activated via software depending on the software version. The time required for the discharge varies depending e.g. on the charge status of the battery pack. A fully charged battery may require up to some hours to be completely discharged. Consider this when activating the discharge and also observe the following note. ) Note: Please be aware that the backup function is not available during discharge. Thus, a primary voltage failure in that time will result in a complete system shut-down. It is recommended to replace the battery pack of the battery backup option after two years of usage as a preventive measure. The nominal lifetime of the battery pack is approx. two years under normal environmental conditions.
