Dekolink Wireless channel selective repeaters employ digital processing techniques to attain versatile programmable filter array. The input RF signal is sampled and converted to digital signals. The digital signal is filtered using fast parallel logic. Using digital processing techniques the system generates up to 8 (12 optional) separate, programmable and independent filters. The filter parameters can be easily modified and tailored to meet specific customer requirements. 3.1 Computer Program. Repeater Management Software (RMA) supplied with the repeater and provide full access to all control setting and monitoring capabilities. The RMA software can be installed on Windows 95, Windows 98, Windows 2000 & Windows XP operation systems. Dekolink's Repeater Management Application software (RMA) is used to manage and control the repeater by local connection via RS232 or remotely by Modem. 3.2 Programmable Modules All Repeater settings made trough Controller unit (CB-04), This unit controls the active components in the repeater, and communicate with two DDF (Dekolink Digital Filter) units Up& Downlink trough RS232 Communication. The controller controls RF Gain, Power On/Off, AGC On/Off & provides Alarms Report . The controller also set DDF parameters to each DDF units (Uplink & downlink) it sets Center Frequency, Bandwidth & Enable/Disable each one of the 8 channels separately of the Uplink/ Downlink path. It allows independence shaping of several filters, by controlling frequency, frequency bandwidth and type.

Dekolink Wireless channel selective repeaters employ digital processing techniques to attain versatile programmable filter arrays in both the uplink & downlink paths. The RF signal entering the repeater, is filtered by a duplexer, amplified, down converted &
sampled to digital signals. The digital signal is filtered using fast parallel logic. Using digital processing techniques, the system generates up to 8 separate, programmable and independent filters. After filtration is accomplished, the digital signals are up-converted to an RF signal, amplified by a High Power Amplifier & combined by a duplexer to the output port.

NOTE! In case that Antennas are not connected, terminate the Base & Mobile marked connectors with a 30dB attenuator, in order to prevent damage (by a regressing signal) to protect the Test equipment. The attenuators power rating should be at least 50W at the Mobile marked repeaters terminal, and 10W at Base marked repeaters terminal.
- Connect power supply. A supplied voltage in the range of 90 to 260VAC should be connected to the repeaters AC power connector.
- Inject to the repeaters Downlink route terminal (Base connector), RF Signal from the connected RF Generator, and a Spectrum Analyzer, to the repeaters Mobile terminal, and test the repeater RF performance (see test set up diagram below).

The RF connector labeled Base must be connected to the antenna pointing to the base station; usually a rooftop antenna. The RF connection labeled Mobile must be connected to the antenna pointing into the area to be covered by the Repeater such as inside a building or outdoor shaded area. The repeater operates from 110V/220 VAC @ 2A. 9.1 AGC (ALC) FUNCTION The repeater has AGC (Automatic Gain or Level Control) function on both paths that serve to prevent the saturation of the power amplifier. The amplifier has a directional coupler and a detector at the output of the high power amplifier to monitor the output power. When a high signal is received the automatic level control detects the amplitude and sends a feedback signal to a voltage variable attenuator that attenuates the signal level so that the output power of the amplifier does not exceed the preset limit. This level control ensures the power amplifier operation in the linear region only. 9.2 RF GAIN SETTING For proper operation of the Repeater, the isolation between the base station antenna and the mobile antenna should exceed the Repeater gain by at least 10 dB. If the Repeater gain is higher than the isolation between the antennas, oscillation will build up and will saturate the amplifier. The step attenuator on the low noise amplifier can reduce the Repeater gain. The repeater gain can be reduced by 31 dB in 1 dB steps. Page 12 of 21 IDEN Digital Repeater Installation Manual 10 BDA INSTALLTION Install the BDA Repeater in a shielded, ventilated and easy to reach area. Use low loss cables to connect antennas to the BDA. Install the BDA close to the service area to improve output power and noise figure. The BDA Base/Donor connector port is connected to donor antenna, usually a Yagi antenna, while the BDA Mobile/Remote connector port is connected to a mobile antenna; outdoor indoor. 10.1 BASE / DONOR ANTENNA INSTALLTION Typically this is a directional antenna such as Yagi or Dish antenna of 10 to 15 dB gain. This antenna is pointed to the base station to get maximum input power. This antenna should be in line of sight with the base site. Raise this antenna higher if no line of site is achieved. The required Base signals should be the dominant signals; at least 6 dB higher power than other signals. Choose the antenna site to get the maximum isolation from the remote (mobile serving) antenna. 10.2 REMOTE / MOBILE ANTENNA INSTALLTION The second antenna is connected via cable that has typical 1~10 dB attenuation (depends on the length of the cable) to the CBDA MOBILE port. This type of antenna is omni directional
(isotropic), or wide beam, with 0 to 2 dBi typical gain and is installed and distributes indoor (in buildings, tunnels, basements, park lots, shopping centers etc.). Typical specifications: gain: 2 dBi, VSWR: better than 2:1, Impedance: 50 ohm. For direct connection to the BDA this antenna must be installed to provide a minimum separation distance of 2 m (200 cm) from persons within the area. Less separation is needed if the power from this power is divided into many antennas covering many floors or areas. Page 13 of 21 IDEN Digital Repeater Installation Manual 10.3 ANTENNA ISOLATION For proper operation the isolation between these two antennas must be at least 10 dB higher than the BDA gain. Lower isolation would lead to high in-band ripple. Oscillations will build up when the isolation is lower than BDA gain. The isolation between the antennas is critical for high gain outdoor repeaters. To measure the isolation, inject a known signal into one antenna and measure the coupled output at the other antenna. This should be done across the frequency range of both uplink and downlink bands. Page 14 of 21 IDEN Digital Repeater Installation Manual 11 INSTALLATION STEPS 1. Install all antennas and connect them to the BDA inputs. 2. Set MAX Gain according to isolation (at least 15 dB lower) and available donor power. This allows the SAGC to smartly limit the output power of the BDA. Optional: The SAGC on the Downlink path guarantees constant downlink power (relative to cell traffic) when and if the Donor power changes. 3. Uplink will set ultimately according to the downlink gain. 4. Check that the uplink FWD power, if power is at constant maximum then isolation between antennas is low (BDA oscillations) or the BDA is faulty. In such a case:
Disconnect one of the cables from the BDA connectors and connect a load at the connectors. If the FWD power is at constant maximum then the BDA is faulty (oscillating) and needs replacing. If FWD power isnt at constant maximum then the isolation between the donor and remote antennas is low. Either improve the isolation (e.g. increase separation) or reduce BDA gain. To reduce gain, reconnect the antenna cables. Reduce the MAX Gain FWD power isnt at constant maximum. Reduce the gain further by 10 dB. Page 15 of 21 IDEN Digital Repeater Installation Manual 12 RF EXPOSURE WARNING In order to satisfy the FCC RF exposure requirements, you must ensure that the installation complies with the following:
One antenna is connected via cable that has typical 1~10 dB attenuation (depends on the length of the cable) to the BDA base port. This antenna is installed outdoor and has very sharp beam
(Yagi type or similar) pointed to the donor (BTS). This type of antenna has about 10dBi gain. Typical specifications: gain: 8 dBd (=10.1 dBi), VSWR: better than 1.5:1, Impedance: 50 ohm. The outdoor antenna must be installed to provide a minimum separation distance of 1 m (100 cm) from persons within the area. The second antenna is connected via cable that has typical 1~10 dB attenuation (depends on the length of the cable) to the BDA MOBILE port. This type of antenna is omnidirecttional
(isotropic), or wide beam, with 0 to 2 dBi typical gain and is installed and distributes indoor (in buildings, tunnels, basements, park lots, shopping centers etc.). Typical specifications: gain: 2 dBi, VSWR: better than 2:1, Impedance: 50 ohm. For direct connection to the BDA this antenna must be installed to provide a minimum separation distance of 2 m (200 cm) from persons within the area. Less separation is needed if the power from this power is divided into many antennas covering many floors or areas.
