2 Introduction Page 15 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. The Node M and Node C are specifically designed to extend coverage, enhance quality, and increase air-interface capacity. In the downlink (DL), the Node M and 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 M and Node C constantly monitors the quality of the signals passing through it, while simultaneously electronically decreasing isolation requirements. 2.2. THE NODE M AND NODE C (NODE M/C) NETWORK ELEMENT Node M and Node C are primary network elements, capable of enhancing up to 20 MHz of continuous spectrum. Their 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. They 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 M is a dedicated UMTS device, but the Node C operates with CDMA technology. However, several enhancers operating at different frequencies and technologies may share the same hardware (cables and antennas) via a crossband coupler. The Node M or 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 M and Node C have 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 interfaces of Node M and Node C provide 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 M and Node C network elements are self-diagnosing, self-adaptive, and virtually maintenance-free. In the following, the expression Node M/C stands for Node M and Node C.

4 Installation Page 294.2. ELECTRICAL INSTALLATION 4.2.1. General Read the health and safety warnings in chapter 1.2 Health and Safety Warnings. 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. For unstable electric networks which frequently generate spikes, it is advised to use a voltage limiting device. 7. A connection of mains supply to a power socket requires the power socket to be nearby the unit. 8. The mains cable must be used exclusively for the repeater. Do not use this cable for the power supply of other devices. 9. Incorrectly wired connections can destroy electrical and electronic components. 10. 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). 11. 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. 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.

Option: 48 Vdc (36-72 Vdc). The external DC breaker should be 20 Amps.
4 Installation Page 334.2.4. Connection of the Antenna Cables The Node M/C’s antenna connectors are 7/16 female (optionally equipped with an N female adapter). 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. Highly directional antennas with good front-back-ratios (40 dB is typical) are recommended because they improve isolation and cell site selectivity. Smaller diameter cables are less expensive and easier to install but have worse performance. 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 M/C.

5 Functional Description Page 375. FUNCTIONAL DESCRIPTION 5.1. DIGITAL ARCHITECTURE The following figure shows the RF block diagram of the Node M/C. figure 5-1 Configuration of a network element The Node M/C is designed to amplify signals between multiple mobiles and a base station in a UMTS/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.
User’s Manual for Node M and Node CNetwork Elements Page 38 M0121A4A.docIn 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 (included in DCM) 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 843 as an example, the following figure illustrates the positions of the RF components inside the Node M/C.

User’s Manual for Node M and Node CNetwork Elements Page 40 M0121A4A.doc 5.2.3. Digital ICE (Digital Interference Cancellation Equipment) Digital ICE has been developed to enhance antenna isolation. This feature enables the Node M/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 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. Isolation and gain margin* can be checked in the “Status and Reports” menu accessible via the home page of the web interface (see software manual). * gain margin = antenna isolation minus Node M/C gain 5.2.4. VSWR (Voltage Standing Wave Ratio) This feature enables the provider to query the status of the antenna system (antenna and 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 of the software, 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.
5 Functional Description Page 41 5.2.5. 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 M/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 M/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. 5.2.6. Alarm Forwarding Alarms can be forwarded to a defined phone number or to the OMC if the Node M/C is equipped with a modem or a mobile station. This enables the provider to control and to query the status of the network via pocket switched or circuit switched connection. Faults and irregularities can be recognized and eliminated. With an optional modem the Node M/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.

5 Functional Description Page 455.2.9. Modems The modem is used to establish a remote connection to the Node M/C. The connection may be used to change the parameters of the unit, check and clear alarms or collect measurement and quality statistics. Furthermore, the modem is at the Node M/Cs request to alert the operator when there is an alarm. The modem may be over-the-air (wireless) or public switched telephone network (PSTN). It is possible to install the wireless modem or the PSTN modem on site. Modem communication settings may only be changed locally. Should a different modem be used, the operator should ensure that the settings are changed prior to leaving the site. Wireless modems allows remote control and maintenance of the Node. Parameters may be changed; alarm and measurement statistics may be acknowledged and collected in the OMC. 5.2.9.1.

User’s Manual for Node M and Node CNetwork Elements Page 48 M0121A4A.doc5.2.10. 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 M/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 DL and UL part. figure 5-15 Digital channel module, DL part figure 5-16 Digital channel module, UL part 1 2 2 7 3 4 6 45 No Explanation 1 1 Vdc and remote (RS232) for modem 2 Debug-connector 3 Fan connector (Node x43) 4 Vdc DL digital channel module 5 Battery backup connector 6 EAC-board connector 7 Internal DCM - DCM interface connection 1 Only one modem can be used at the same time.

5 Functional Description Page 555.2.12. Battery Pack - Battery On/Off 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 DCM and the modem to operate for a limited period of time (battery backup time). Within this time, the Node M/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 pack is protected from deep discharge. When performing preventive maintenance, make sure that all circuits are voltage free by disconnecting the battery cable from the DCM. In case of a power cycle, it is sufficient to press the “Battery disconnect button” on the EAC-board to interrupt the voltage supply.
