PRODUCT MANUAL COMPACT REPEATER DEKO3178B DEKOLINK WIRELESS LTD. Page 6 Proprietary Data Pub. 300TC80031 Rev. 1.55 1111 INTRODUCTION INTRODUCTION INTRODUCTION INTRODUCTION Deko3178B is a dual-band 700/800 MHz band selective mid-power amplifier in a single compact unit. Specially designed for public safety in-door networks, the Deko3178B small foot-print and flexible installation options minimize interference with operations on the floor on which it is installed. It can be installed in a rack, mounted on a wall or on the ceiling. It’s relatively low weight which allows mounting and maintenance by a single person, in addition to the simple commissioning procedure that does not require a high level technician, provides significant savings on labor costs. The Deko3178B can be remotely monitored via an external wireless modem connected to dry-contacts on the unit. It can be remotely accessed through a secure website or through a third-party NMS via SNMP traps. Figure 1-1: Deko3178B Dual Band BDA 1.1 FEATURES • Band selective, mid-power amplifier for public safety in-building network • Dual-band SMR 700/800 MHz in a single unit • Composite power (See Appendix A) • 80 dB RF gain • Small footprint and light weight for easy maintenance • RF SAW filtering • Gain matching uplink and downlink • Alarm indication by LED and Dry contact • Manual Gain Control • High linear amplification • Ideal for in-building and out-door coverage solutions • Relative small size and light weight • Cost effective solution • Wall mounted easy Installation • Reliable operation, maintenance free
DEKOLINK WIRELESS LTD. COMPACT BI-DIRECTIONAL AMPLIFIER DEKO3178B PRODUCT MANUAL Pub. 300TC80031 Rev. 1.55 Proprietary Data Page 7 1.2 DEKO3178B BLOCK DIAGRAM DESCRIPTION The CBDA Downlink path receives the RF signal from the base station, amplifies it and transmits it to the subscriber. The BDA Uplink path receives the RF signal from the subscriber amplifies it and transmits it to the base station. Two triplexers at the Dual Band BDA’s input and output separate the uplink and downlink frequency bands, creating high isolation between them and enabling the appropriate amplification of the signals in each path. Each path contains two amplifiers and an RF SAW Filter that provides signal filtration and amplification. In addition, the Dual Band BDA power amplifiers have an ALC option switch. When switched on, the ALC circuit limits the amplifier output power. The ALC circuit senses the output power and introduces more attenuation, when the output power exceeds the preset level. This way the gain of the amplifier is reduced, its output power is limited and the intermediations products are kept below the desired level. Warning: The AGC switch must be always ON in order to limit the spurious signals. The gain of each path can be set manually. The separation of the gain setting architecture enables setting the actual gain for each path. Figure 2. Deko3178B Functional Block Diagram

Upon detecting a fault or when the power is cut off from the CBDA the relay alarms open. • The relay alarms are connected to pins 3 and 4 of the front panel Alarms connector used for remote sensing of faults. 3.4 GROUNDING Once the Dual Band BDA is installed, you are required to ground it. The Dual Band BDA case includes a grounding lug, where a grounding conductor cable should be attached. The Dual Band BDA grounding conductor is found at the right-hand side of the bottom panel. The protective grounding conductor should be copper with cross-section of 10AWG. The lug of the protective conductor should also be aluminum. Washers and screw should be high CR stainless steel, or 12% stainless steel, or 12% Cr stainless steel, or Cr on steel, Ni on steel, tin on steel. 3.5 POWER UP To power-up The Dual Band BDA operates from a 100/240 VAC Mains. The maximum consumption power is 105W. Connect the AC power cable to the Dual Band BDA front panel AC IN (100-240VAC) connector. Figure 9.Power Up Connection 100-240VAC

The step attenuator on the low noise amplifier can reduce the CBDA gain. The CBDA gain can be reduced by the amount indicated on the step attenuator. Note: A higher CBDA gain than the isolation between the antennas would cause oscillation which would saturate the amplifier. On the other hand, if the isolation were only a few db higher than the CBDA gain, it would not be enough to cause oscillation however it would cause gain ripple in the band. 4.2 ANTENNA INSTALLATION 4.2.1 Base (Donor) Antenna NOTE: Verify that the antennas meet requirements described in section 2.2.1. Installation requirements: • The antenna should point to the direction of the base station for maximum input power • Verify that the antenna is in the base stations line of sight (raise the antenna if necessary) • Install the donor antenna at a higher level (i.e. floor) than the mobile antenna • Must be installed at a minimum distance of 1 meter from any personnel within the area. 4.2.2 Mobile (Service) Antenna NOTE: Verify that the antennas meet requirements described in section 2.2.2. Installation requirements: • Install the service antenna on the ceiling or on the wall so it would shadow the required coverage area within the in building environment. • Installation of this antenna must provide a minimum separation distance of 0.5 m from any personnel within the area. • Cable and jumper loss is at least 2dB.
DEKOLINK WIRELESS LTD. COMPACT BI-DIRECTIONAL AMPLIFIER DEKO3178B PRODUCT MANUAL Pub. 300TC80031 Rev. 1.55 Proprietary Data Page 17 4.3 ANTENNA CONNECTIONS Note 1: Do not operate the Dual Band BDA without terminating the antenna connections with actual antennas or proper dummy loads. Note 2: If the coaxial cables are NOT weather-resistant type, wrap the exterior coaxial cables with insulation and holding tape (Type 3M Rubber splicing tape) for environmental protection and to ensure longer lifetime. To connect the antennas to the Dual Band BDA • Connect the Donor antenna to the Dual Band BDA BASE port. • Connect the Service antenna to the Dual Band BDA MOBILE port. Figure 4-1.Deko3178B – Antenna Connections 4.4 VERIFYING ISOLATION BETWEEN DONOR AND MOBILE ANTENNAS The isolation between the Base/Donor and Mobile/Service antennas is critical especially for high gain, outdoor applications. For proper operation of the Deko3178B Dual Band BDA, it is recommended that the isolation between the Donor and Service antennas be at least 15 dB higher than the Dual Band BDA set gain. The isolation between the antennas is critical for high gain outdoor Dual Band BDA. To measure the isolation; inject a known signal into one antenna and measure the power at the other antenna. This should be done across the frequency range of both uplink and downlink bands. NOTE: Lower isolation can lead to high in-band ripple, oscillations and low signal quality. To measure the isolation, proceed as follows: 1. Inject a known signal from a signal generator into one antenna (preferably the Donor antenna).
PRODUCT MANUAL COMPACT REPEATER DEKO3178B DEKOLINK WIRELESS LTD. Page 18 Proprietary Data Pub. 300TC80031 Rev. 1.55 2. Measure the coupled output from the Service antenna, using the Spectrum analyzer and LNA if applicable. 3. Perform this procedure across the frequency range of both the Uplink and Downlink bands. 4. Register the lower result for system operation. NOTE: The SALC feature overcomes this procedure. 4.5 VERIFYING THE LINK BETWEEN THE BTS AND THE DUAL BAND BDA This test checks the signal strength from the BTS antenna to the CBDA Dual Band BDA. Proceed as follows: 1. Using a Spectrum analyzer, measure the received signal from BTS at the Donor antenna port near the Dual Band BDA. 2. Adjust the Donor antenna direction to receive the maximum signal strength. 3. Compare the received signal strength with the calculated signal strength from the design phase. In case of discrepancy, check for one of the following: • 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.

A monitor circuit monitors these elements and initiates an alarm upon detecting a deviation from the normal operation. The summarized alarm output of the monitoring card is sent to the corresponding front panel Alarm connector. The monitor circuit performs the following functions: • Monitors the current of uplink power amplifier - If the current is either below or above the specified limits an automatic alarm function is provided through a lit LED and a dry contacts relay. • Monitors the downlink RF output power - If the output power is lower than +20dBm an alarm function is provided by a lit LED and a dry contacts relay. Indication Cause Action Downlink LED is ON Indicates low RF power at downlink path <20 dBm) Check base antenna connection Check antenna alignment to base.
