ADCP-75-237 • Issue 1 • 8/2007 • PrefacePage vii© 2007, ADC Telecommunications, Inc.ABOUT THIS MANUALThis manual describes the installation and operation of the ADC In-Building Wireless Repeater. The repeater is normally mounting inside and distributes the RF over coax to an indoor antenna located in the desired coverage area.ADMONISHMENTSImportant safety admonishments are used throughout this manual to warn of possible hazards to persons or equipment. An admonishment identifies a possible hazard and then explains what may happen if the hazard is not avoided. The admonishments — in the form of Dangers, Warnings, and Cautions — must be followed at all times. These warnings are flagged by use of the triangular alert icon (seen below), and are listed in descending order of severity of injury or damage and likelihood of occurrence.Danger: Danger is used to indicate the presence of a hazard that will cause severe personal injury, death, or substantial property damage if the hazard is not avoided.Warning: Warning is used to indicate the presence of a hazard that can cause severe personal injury, death, or substantial property damage if the hazard is not avoided.Caution: Caution is used to indicate the presence of a hazard that will or can cause minor personal injury or property damage if the hazard is not avoided.GENERAL SAFETY PRECAUTIONSList here all general admonishments which apply throughout procedures within the manual.-Warning: Wet conditions increase the potential for receiving an electrical shock when installing or using electrically-powered equipment. To prevent electrical shock, never install or use electrical equipment in a wet location or during a lightning storm. Danger: This equipment uses a Class 1 Laser according to FDA/CDRH rules. Laser radiation can seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do not look directly into the optical transceiver of any digital unit or exposure to laser radiation may result. An optical power meter should be used to verify active fibers. A protective cap or hood MUST be immediately placed over any radiating transceiver or optical fiber connector to avoid the potential of dangerous amounts of radiation exposure. This practice also prevents dirt particles from entering the adapter or connector.Caution: This system is a RF Transmitter and continuously emits RF energy. Maintain 3 foot (91.4 cm) minimum clearance from the antenna while the system is operating. Wherever possible, shut down the RAN before servicing the antenna.
Caution: Always allow sufficient fiber length to permit routing of patch cords and pigtails without severe bends. Fiber optic patch cords or pigtails may be permanently damaged if bent or curved to a radius of less than 2 inches (5.1 cm). Caution: Exterior surfaces of the RAN may be hot. Use caution during servicing.

The device is connected via coax to a donor antenna that is typically located on a rooftop or external wall of a building, directed at the donor cell-site. The repeater is mounted inside the building and distributes the RF over coax to an indoor antenna located in the desired coverage area.1.1 RF SIGNAL FLOW (850MHz)1.1.1 Forward (Down) LinkThe base station signal raging from 869 ~ 894MHz is received by the Donor antenna. Then going through the duplexer removing the unwanted signals received by the LNA. The forward link signal received by the LNA goes through a BPF (Band Pass Filter) then is amplified by the drive amplifier. The signal then goes through the LAN, and a Down Mixer where IF signal conversion is done. This IF signal then goes through an IF SAW Filter adding two banda of 11+1.5MHz and 10+2.5MHz, totaling 25MHz, after filtering the signal. This signal now moves to an up mixer to be converted to RF frequency and sent to a final stage amplifier. The final stage amplifier’s output power goes through duplexer. The signal then goes through the service antenna transmitting the forward link signal to the handsets.
ADCP-75-237 • Issue 1 • 8/2007 • Section 1: OVERVIEWPage 1-2© 2007, ADC Telecommunications, Inc.1.1.2 Reverse(Up) LinkThe reverse link and the forward link have a same structure. Frequency raging from 824 ~ 849MHz received by the service antenna go into the duplexer. The duplexer removes all unwanted signals and sends the specific signal to the LNA. The reverse link signal received by the LAN is amplified by the drive amplifier and Down Mixer where IF signal conversion is done.The IF signal then goes through IF SAW Filter adding two bands of 11+1.5MHz and 10+2.5MHz, totaling 25MHz, after filtering the signal. This signal now moves to up mixer to be converted to the RF frequency and sent to a final stage amplifier. The signal in final stage amplifier undergoes through duplexer. Then the signal goes through the donor antenna, transmitting reverse link signal to base stations.1.2 RF SIGNAL FLOW (1900MHz)1.2.1 Forward(Down) LinkThe base station signal ranging from 1930 ~ 1990MHz is received by the Donor antenna. It passes through the duplexer removing the unwanted reverse path signals received by the LNA. The forward link signal received by the LNA goes through a BPF (Band Pass Filter) then is amplified by the drive amplifier. The signal than goes through the LNA and a Down Mixer where IF signal conversion is done. This IF signal then goes through an IF SAW Filter adding two bands of 15MHz and 5MHz, totaling 20MHz, after filtering the signal. This signal now moves to an up mixer to be converted to the RF frequency and sent to a final stage amplifier. The final stage amplifier's output power goes through the duplexer. The signal then goes through the service antenna transmitting the forward link signal to the handsets.1.2.2 Reverse(Up) LinkThe reverse link and the forward link have the same structure. Frequencies raging from 1850 ~ 1910MHz received by the service antenna go into the duplexer. The duplexer removes all unwanted signals and sends the specific signal to the LNA. The reverse link signal received by the LAN is amplified by the drive amplifier and Down Mixer where IF signal conversion is done.The IF signal then goes through IF SAW Filter adding two bands of 15MHz and 5MHz, totaling 20MHz, after filtering the signal. This signal now moves to up mixer to be converted to the RF frequency and sent to a final stage amplifier. The signal in final stage amplifier undergoes through duplexer. Then the signal goes through the donor antenna, transmitting reverse link signal to base stations.

After five minutes, the repeater checks and monitors the RF Power, if the RF output power is above the maximum, repeater remains shut down. If RF output power is back to normal, the repeater comes back on.2.6 Graphical User Interface (GUI)The GUI control interface is used to change to Sleep Mode, select different bands A, B, C, D, E, and F of the US PCS service. Other features of the BDU such as the On/Off controls of the system can be accessed through the USB port provided. All control is set “Automatic” when shipped, you can change the setting using the GUI control interface provided.

Repeater must be installed within six feet of an AC power source (100–240 VAC 50 or 60 Hz). The repeater mounting bracket has four mounting holes, as shown in Figure 2-1. Below are guidelines for standard wall mount and masonry wall mount of the repeater.Figure 2-1. Wall Mount Bracket1.1 Mechanical Attachment of RepeaterWarning: Never install the repeater in a wet location or during a lightning storm. When installing or modifying communication lines, disconnect lines at the interface before working with uninsulated lines or terminals to prevent electrical shock.1.1.1 Standard Wall MountWhen mounting the repeater on a wooden or metal surface, it is recommended that it be installed on pressure-treated plywood (customer provided) with a minimum thickness of 0.75–inch (19.0 cm). The plywood should be firmly secured to the wall studs.1.1.2 Masonry Wall MountWhen mounting the repeater on a masonry surface, it is important that the bolts (especially the upper bolts) be located as close as possible to the center of bricks or blocks.
