DEKOLINK WIRELESS LTD. PRODUCT MANUAL IDEN REPEATER 2. FUNCTIONAL DESCRIPTION 2.1 GENERAL This repeater is designed to help improve communications signal by extending the coverage of a base station. The Donor (Base) antenna receives the signal from a base station and conveys it to the CDMA Repeater. The Repeater amplifies the signal. After amplification, the signal is passed through to the Mobile antennas. 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 CDMA Repeater is processed similarly for both the Uplink and Downlink paths. Figure 1 provides a functional block diagram of the CDMA Repeater. Figure 1: CDMA Repeater - Block Diagram The block diagram showed in Figure 1 illustrates the overall functionality of the CDMA Repeater. Dekolink’s programmable CDMA Repeaters employ advanced up/down conversion Intermediate Frequency (IF) Surface Acoustic Waves (SAW) filtering architecture. This new technology offers distinct advantages over conventional repeaters, when high adjacent selectivity and spectrum purity is required. The Channeler Module (center unit) consists of dual Radio Frequency Up/Down Converter sub-modules for Downlink and Uplink paths. The Channeler amplifies the received RF signals and converts them into an intermediate frequency (IF). The IF outputs are connected to a SAW Filter. The IF outputs are converted back to the original RF frequencies. The cellular modem is an option for remote monitoring and repeater parameters control. Pub. 311-2005 Rev. 1.0 Proprietary Data Page 5

DEKOLINK WIRELESS LTD. PRODUCT MANUAL IDEN REPEATER 3.2 COMPONENTS GENERAL DESCRIPTION A description of the main components of the CDMA Repeater follows. 3.2.1 Channeler The Channeler Module consists of dual Radio Frequency (RF) Up/Down Converter sub- modules for Downlink and Uplink paths. The Channeler amplifies the received RF signals and converts them into an intermediate frequency (IF). The IF outputs are connected to a SAW Filter. The IF outputs are converted back to the original RF frequencies. The Channeler also has controllable attenuators (32 dB range in steps of 1dB)and a pre-amplifier for each path. 3.2.2 Monitor Module The Monitor Module measures the current of the following elements of the Repeater: Up/Down Converter, Uplink Power Amplifier, and Power Supply. It also senses the Downlink output power. If a module fails, an appropriate report is sent to the Control Box and the Summarized alarm red LED lights up. 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 Power Supply The Power Supply module allows a wide range of input power from different sources: 90 to 260 VAC, maximum power consumption - 150W. The output power provided to the Repeater internal modules is: 28 VDC, 15VDC and 9 VDC. 3.2.5 Duplexers The duplexers isolate the transmit path from the receive path. The pass bandwidth of the duplexer is the entire width of the Uplink band and the Downlink band respectively. 3.2.6 Power Amplifier The power amplifier is the final stage of both the Downlink and Uplink paths. The CDMA Repeater includes Power Amplifiers with relatively high Third Order Intercept Point (IP3) figures, thus allowing high output power while preserving high linearity of the output signals.

IDEN REPEATER PRODUCT MANUAL DEKOLINK WIRELESS LTD. 3.3 REPEATER FEATURES 3.3.1 Controller The integrated Controller Module (Control Box) has three main functions: 1. Detects faults in the repeater and issues an alarm indication. 2. Controls the active components in the Repeater and enables the main parameters setting :  Max Power  RF Gain,  Power On/Off,  AGC On/Off  SALC On/Off 3. Monitors key operating functions:  DC supply voltage  Downlink output power  Heatsink temperature. Two modes of monitoring and control are available: External PC - through the serial interface connector in the Control Box. • • Remote control - via a modem connected to the Control Box serial interface. A standard or cellular modem can be installed inside the Repeater enclosure, refer to Appendix D. The Repeater’s Alarm, Control and Monitor functions are performed by Dekolink’s RMT software. For more information, see the RMT User's Guide. The Controller transmits in two modes: Polling and Burst. When operating in Burst Alarm mode, the Controller generates a burst alarm and reports the faults to the local or remote connection. The Controller software handles the alarm reporting and parameters transmission to the Repeater’s outside world. 3.4 SMART-ALC FUNCTION 3.4.1 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 RF Gain to an optimal value. Some of the SALC advantages are: Network friendly: The SALC periodically learns traffic conditions and set the gain so that at maximal traffic the repeater output is at maximal value. In all other cases the gain is constant and the output power follows the BTS fluctuations. This feature introduces system transparency – the mobile using the repeater is not affected by repeater existence. Repeaters that blindly amplify the pilot code (minimal Page 8 Proprietary Data Pub. 311-2005 Rev. 1.0
DEKOLINK WIRELESS LTD. PRODUCT MANUAL IDEN REPEATER transmission) of a certain base station to maximum output power might generate network problems (they unnecessarily increase the noise in a certain cell). By keeping the same gain for full traffic as well as for pilot only transmissions situations, the Dekolink CDMA SALC feature minimizes this effect. No adjustments are required: When installing the repeater, the standard procedure for the technician is to tune the repeater to the desired isolation and gain values. With SALC, the tuning procedure is accomplished automatically, thus saving precious workmanship and equipment usage time for a “plug & play” foolproof deployment. Uplink and downlink balance is preserved. In previous repeaters, separate adjustments are required for the uplink and downlink. This repeater requires just one adjustment for both channels. If the gain of downlink path changes by some value, the uplink path is changed by the same value. Both channels have to be balanced for the proper seamless integration of the repeater in the network. Unbalanced operation bares the risk of reducing the dynamic range of the base station itself. Reduction of isolation problems: .This repeater does not oscillate. Whenever the isolation drops for some reason the repeater automatically senses the oscillations and automatically reduces the gain in accordance with the new isolation conditions. Once the isolation problem is solved the repeater automatically raises the gain again. This operation is remotely monitored, and if required, remote controlled. SALC - Summary: Conventional CDMA/WCDMA repeaters often interfere in the network when strong traffic raises the repeater input signal level, which as a result activates the ALC algorithm of the system. Once under ALC, the conventional system is no longer in its linear dynamic range, hence creating interferences in the cell shrinking or expanding procedures. The Smart ALC solves this problem and thus reduces the need for adjustments. The repeater does not interfere with the network shrinking or expanding processes and thus becomes “network friendly “. 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 maintains Uplink/Downlink balance. 3.4.2 ALC Function The Repeater includes the Automatic Level Control (ALC) function on both the Uplink and Downlink power amplifiers to prevent output power from exceeding maximum allowed output power. 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. In normal operation (SALC ON) the regular ALC is not active. The ALC is factory preset to ON state. Pub. 311-2005 Rev. 1.0 Proprietary Data Page 9
IDEN REPEATER PRODUCT MANUAL DEKOLINK WIRELESS LTD. 3.4.3 RF Gain Setting The gain value should be set via the RMT in accordance with the input signal power at the Donor antenna, and the required Downlink output power. Special care should be taken not to exceed the isolation limit. It is recommended to set the Downlink path gain to a maximum value that is 12 dB below the isolation between the Base antenna and the Mobile antenna. The gain range is 59-90 dB. Use the Max Gain field for Downlink GAIN setting and the Gain Delta field to determine the GAIN difference between Uplink and Downlink path (Uplink GAIN follows Downlink GAIN by “Delta” dB). Refer to Section 5.5 Note When you set the gain to 60 dB the Maximum Output Power will degrade due to overload input power. The maximum input power you can inject is –25 dBm.

DEKOLINK WIRELESS LTD. PRODUCT MANUAL IDEN REPEATER 4. INSTALLATION 4.1 SAFETY INSTRUCTIONS Before installing the repeater, review the following safety information: Follow all local safety regulations when installing the repeaters. • • • • • • • • • Only qualified personnel are authorized to install and maintain the repeater. When operating the repeater, it is recommended to keep its cover closed while the power is on. Some maintenance tasks may require the repeater door to be opened while the power is on. In such cases, perform the required tasks carefully and remember to close the repeater cover/door when finished. Use a suitable mounting surface, such as a rigid wall. Follow Electro-Static Discharge (ESD) precautions. Before closing the repeater cover, make sure no wires are in the way. Install the repeater close to the service area to maintain the output power and noise figure. Use low loss cables to connect the antennas to the repeater. Install the repeater in a shielded, ventilated, and easy-to-reach area. 4.2 RF EXPOSURE WARNING 4.2.1 General In order to satisfy the FCC RF exposure requirements, it must be ensured that the installation complies with the following requirements. 4.2.2 Donor Antenna requirements The Donor antenna connected to the BASE port in the Repeater is usually installed outdoor. This antenna (Yagi type or similar) has a 12-20 dBi gain, and features a very sharp beam pointed to the BTS. Cable and jumper loss is at least 2dB. The Donor antenna must be installed to provide a minimum separation distance of 0.75 m from any personnel within the area. 4.2.3 Mobile Antenna requirements The second antenna is connected to the MOBILE port in the Repeater. This interface serves either an Outdoor antenna or an Indoor antennas array, in accordance with the application. In case of Outdoor application, the antenna type is omnidirectional (isotropic) with 0 to 2 dBi typical gain, or wide beam with up to 10 dBi gain. This antenna is installed on a mast to cover a shadowed outdoor area. Cable and jumper loss is at least 2dB. Installation of this antenna must provide a minimum separation distance of 1 m from any personnel within the area. Pub. 311-2005 Rev. 1.0 Proprietary Data Page 11
IDEN REPEATER PRODUCT MANUAL DEKOLINK WIRELESS LTD. In case of Indoor coverage, the output power is split into several, omni directional antenna with 0 to 2 dBi typical gain, and distributed to different indoor areas (in building floors, tunnels, basements, parking lots, shopping centers etc.). At least 5 such antennas must be connected to the Repeater with cables and splitters. In this application, the maximum ERP from each antenna shall not exceed 1.5W. Consequently, the minimum required separation distance from any personnel within the area is 30 cm. Less separation is needed if the power is divided into more than 5 antennas covering many floors or areas. 4.3 REPEATER INSTALLATION SITE VERIFICATION 4.3.1 General This section provides the required procedures for the verification of the operating environment of the CDMA Repeater, to be performed before connecting the unit and before its operation. 4.3.2 Verifying the Link Between the BTS and the Repeater This test checks the signal strength from the BTS antenna to the CDMA Repeater. Proceed as follows: Using Spectrum analyzer, measure the received signal from BTS at the Donor antenna port near the repeater • • • • • • • Adjust the Donor antenna direction to receive the maximum signal strength. Compare with the calculated signal strength from the design phase In case of mismatch, check for cause: - 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. 4.3.3 Verifying the Antenna Isolation The isolation between the Base/Donor and Mobile/Service antennas is critical especially for high gain, outdoor applications. For proper operation of the CDMA Repeater, Dekolink recommends that the isolation between the Donor and Service antennas be at least 12 dB higher than the repeater set gain. Note Lower isolation can lead to high in-band ripple, oscillations and low signal quality. To measure the isolation, proceed as follows: Inject a known signal from a signal generator into one antenna (preferably the Donor antenna) Page 12 Proprietary Data Pub. 311-2005 Rev. 1.0
