DIGITAL REPEATER PRODUCT MANUAL DEKOLINK WIRELESS LTD. 2. FUNCTIONAL DESCRIPTION 2.1 GENERAL This repeater is designed to help improve communications signal and coverage by extending the coverage of a base station. The outdoor Donor (Base) antenna receives the signal from a base station and conveys it to the Digital Repeater. The Repeater amplifies the signal. After amplification, the signal is passed through to the Mobile antennas, either outdoor or indoor. Conversely, signals from handsets are amplified and retransmitted by the Repeater to the base station. 2.2 FUNCTIONAL DESCRIPTION The incoming signal processing in the Digital Repeater is processed similarly for both the Uplink and Downlink paths. Figure 1 provides a functional block diagram of the Digital Repeater. Figure 1: Digital Repeater - Block Diagram The incoming RF signal from either the Base antenna (from the BTS) or from the Mobile antenna (from the mobile handset) enters the Repeater and is first filtered by the Duplexer. The incoming signal is amplified by an Automatic Gain Control (AGC) amplifier, then down-converted. The input RF signal is then sampled and converted into a digital signal. This digital signal is filtered using fast parallel logic. The Repeater generates up to eight separate, programmable, and independent filters using digital processing techniques. These programmable filters sort the digital signal. Page 4 Proprietary Data Pub. 302-2004 Rev. 2.0
DEKOLINK WIRELESS LTD. PRODUCT MANUAL DIGITAL REPEATER After filtration, the digital signals are converted back into analog signals and up-converted to RF signals by the Up-Converter. The output RF signal is then amplified by a High Power Amplifier, and combined by a duplexer before output. The output signal is emitted by the antennas, either towards the BTS in case of a signal from the mobile handset, or to the Outdoor antenna or to the Indoor antennas array, in accordance with the application.

DIGITAL REPEATER PRODUCT MANUAL DEKOLINK WIRELESS LTD. 3.2 COMPONENTS GENERAL DESCRIPTION A description of the main components of the Digital Repeater follows. 3.2.1 Channeler The Channeler Module consists of the dual Radio Frequency (RF) Up/Down Converter sub-modules for Downlink and Uplink paths. The Channeler amplifies the input RF signals and converts them into an intermediate frequency (IF). The IF outputs of the Channeler are routed to the Dekolink Digital Filter (DDF) modules. In the DDF, the IF inputs from the Channeler are converted back to their original frequencies. The Channeler also includes digital controllable attenuators (range 32 dB, in steps of 1 dB) and a pre-amplifier for each path. 3.2.2 Monitor Module The Monitor Module monitors the Repeater operation and provides a visual warning whenever it detects a failed module or function. The monitoring is performed by measuring the current of several elements: DDF Uplink and Downlink, • • • • Up/Down Converter, Uplink Power Amplifier, and Power Supply. If a module fails, the appropriate red LED lights up and a report is forwarded to the Control Box. For a more detailed description of the module, refer to paragraph 3.3. 3.2.3 Controller The Controller (also called Control Box) controls and monitors the parameters in all modules of the Repeater. It provides local or remote connection to a PC (See Dekolink’s RMT User's Guide for more information.). For a more detailed description of the module, refer to paragraph 3.3. 3.2.4 Digital Filter Module Dekolink’s Digital Filter Module uses digital processing techniques to generate up to eight separate, programmable, and independent filters. These filters are activated in both the Downlink and the Uplink paths. The filter parameters can be modified and tailored to meet the customer’s specific applications requirements. 3.2.5 Connections Box The Connections Box module interconnects the Repeater Modules. This box includes the Repeater ON/OFF switch and the power fuses. Page 8 Proprietary Data Pub. 302-2004 Rev. 2.0

Set the maximum transmitted power for Downlink and Uplink(Max Power) according to the actual onsite requirements Set the Max Gain according to the measured/calculated input power. Dekolink recommends setting the Maximum Gain value to approximately 18 dB less than the isolation between the antennas/ If you use SALC, there is no need to measure or calculate the gain in accordance with the required output power because it is adjusted automatically to attain the selected power. (For more information, see section 9.4, Smart-ALC Function). Page 20 Proprietary Data Pub. 302-2004 Rev. 2.0

The current digital filter configuration in the Repeater is displayed Set the filter configuration (number of filters, frequencies and filters type) in the Downlink page Activate the relevant channels by clicking √ in the On/Off checkbox Select the Uplink tab and set the digital filter configuration accordingly. After defining the digital filters (Downlink and Uplink), download the new data to the repeater so that the information can go into effect. 6.1.3 Saving the Settings Two ways to save the settings into the repeater are available: Download to RAM for temporary setting, and Burn-in to Flash for permanent setting. To savethe settings: Click Download to RAM. This technique is recommended for trials, tests and preliminary setup of the digital repeater until the final configuration of the digital filters is achieved. You can download the settings an unlimited number of times using Download to RAM. This process is however volatile and the information will be lost in the event of a power failure. The DDF parameters are kept in a volatile memory only, and should be burned to a Flash memory at finalization of the process. Click the Burn-in to Flash button to download the data to a non-volatile (FLASH) memory. You can download the data to the Flash memory a relatively large but limited number of times (several hundreds). It is recommended to burn the data into the Flash memory only, after you are satisfied with the filter settings for the required application and intend to use it for long period of time. To finalize the procedure: Disable the Mute for the downlink and uplink amplifier and test the performance in the coverage area. (Mute is the output power on/off control, which can be set via “P.Amp On” checkbox.) Save the configuration files of the digital filters by selecting File / Save configuration in the Digital Filter Application and assigning a appropriate name to the file. This data is not saved in the RMT Database. Pub. 302-2004 Rev. 2.0 Proprietary Data Page 21
DIGITAL REPEATER PRODUCT MANUAL DEKOLINK WIRELESS LTD. 6.2 SMART-ALC FUNCTION 6.2.1 SALC Description The Smart Automatic Level Control (Smart-ALC) is an innovative solution for automatic repeater gain adjustment. Combined with advanced control algorithms, SALC can perform gradual learning of traffic load characteristics and adjust the Repeater Gain to the desired value. This automatic operation practically removes the need to make initial settings for maximal traffic load conditions and eliminates the need for numerous site visits to take care of Gain adjustment. SALC also reduces isolation problems and Sync amplification, and maintains Uplink/Downlink balance. 6.2.2 ALC Function The Repeater includes the Automatic Level Control (ALC) function on both the Uplink and Downlink power amplifiers to prevent the saturation of the amplifier. The amplifier includes a directional coupler and a detector that monitor the output power. The ALC mechanism samples the output power, and decouples and rectifies it. The ALC mechanism sends a feedback signal to a voltage variable attenuator (VVA) that, whenever a high input signal is received, attenuates the signal level so that the output power of the amplifier does not exceed the preset limit. This level control ensures that the power amplifier operation stays within the linear region only, thus preventing saturation and signal distortion. The ALC protects the amplifiers from overloading and prevents the system from generating spurious emissions. ALC limits the output power to a constant value (Maximum output power). The ALC is factory preset to ON state. 6.2.3 RF Gain Setting The gain range is 59-90 dB. The RF Gain is set separately for Uplink and Downlink. The gain range should be set via the RMT in accordance with the input signal power at the Donor antenna, and in accordance with the required Downlink output power. The gain range is set using the Max Gain function (beware not to exceed isolation limits, see note below). The Uplink Gain is set by the Gain Delta field (that is the difference between the Downlink Gain and the Uplink Gain) in accordance with the system needs. Note that usually this field is set to “0” for system transparency. Please refer to Installation Manual. Note It is recommended to set the Downlink path gain to a maximum of 18 dB below the isolation between the Base antenna and the Mobile antenna. Page 22 Proprietary Data Pub. 302-2004 Rev. 2.0

DEKOLINK WIRELESS LTD. PRODUCT MANUAL DIGITAL REPEATER APPENDIX B: ALARMS AND LEDS General Alarms In case of failure, the repeater triggers an alarm message and transmits its alarm status to the NMS through a remote or local PC connection In addition, the relevant LED lights up in the Repeater external front panel. The major alarms issued by the Digital Repeater are described below. A description of the LEDs statuses is provided in following paragraphs. Temperature Alarm This alarm is triggered when the chassis temperature exceeds 60C° (ambient) within the Repeater case. Main Voltage Alarm This alarm is triggered when the Power Supply voltage is outside its limits. The operating voltage is 28V. Monitor Module Alarms General The Monitor Module controls, by measuring the current, major functions of the Repeater, such as: DDF Uplink and Downlink, • • • • Up/Down Converter, Uplink Power Amplifier, and Power Supply voltage. Some of these alarms trigger a red LED on the Repeater Monitor Module. Figure 12: Monitor Module – LEDs Location Pub. 302-2004 Rev. 2.0 Proprietary Data Page 31
DIGITAL REPEATER PRODUCT MANUAL DEKOLINK WIRELESS LTD. Uplink and Downlink Alarms A list of Uplink and Downlink alarms is provided below. Power Amplifier Uplink Forward Power Amplifier Current Alarm: This alarm is triggered when the Power Amplifier current is outside of its specified limits. Downlink Threshold Forward Output Power Alarm: This alarm is triggered when the Power Amplifier output is lower than the specified limits. Channeler This alarm is triggered when the Channeler current is outside of its specified limits. Channeler Lock-Detect This alarm is triggered when the Channeler synthesizers are unlocked. DDF Current This alarm is triggered when the DDF current (including the internal fan) is outside of the specified limits. Voltage Standing Wave Ratio (VSWR) This alarm is triggered when the return loss of the Downlink antenna or cable connection exceeds 6 dB (VSWR 3:1). The VSWR module measures the voltage standing wave ratio of the Downlink output antenna port. If the VSWR falls below 13 dB, an alarm is triggered. 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. The alarm can be forwarded to the RMT so that faults and irregularities can be recognized and eliminated rapidly. DDF Communication DDF communication is triggered when the Repeater Controller fails to communicate with the DDF unit. The communication with digital repeater components is made via the Control Box. If the Controller fails to read/update parameters with the Digital Filter module, it triggers the communication alarms. Measurements Temperature Measurements: Measures ambient temperature of the digital repeater chassis. A temperature sensor is placed on the heat sink and provides analog voltage to the Control Box. The controller processes the input with a formula and provides the measured temperature. Downlink Forward Power Measurements: Measures the output power of the Downlink (if the output power is less than 30 dBm, 30 dBm is displayed.) This module measures the composite output power in the downlink output path of the repeater. Output Power Alarms If the output power falls below a certain level, an alarm is triggered. You can set the power level and the mask for the alarm. (See the RMT User's Guide for more information.) This feature provides you with the output power of the repeater and thereby achieves optimum output power. Page 32 Proprietary Data Pub. 302-2004 Rev. 2.0
