Part 90 (Class B) Signal Boosters WARNING. This is NOT a CONSUMER device. It is designed for installation by FCC LICENSEES and QUALIFIED INSTALLERS. You MUST have an FCC LICENSE or express consent of an FCC Licensee to operate this device. You MUST register Class B signal boosters (as defined in 47 CFR 90.219) online at www.fcc.gov/signal-booster/registration. Unauthorized use may result in significant forfeiture penalties, including penalties in excess of $100,000 for each continuing violation. Invisible laser light is used on these equipment. DO NOT look directly into the fiber optic connectors when unit is in operation. Connect RF Output to existing Distributed Antenna System (DAS) cable only. DO NOT operate equipment with unauthorized antennas, cables, and/or coupling devices. DO NOT operate equipment unless all RF connectors are secure. DO NOT operate equipment unless it has been installed and inspected by a qualified radio technician. Contact Information For more information contact the FCC at: https://signalboosters.fcc.gov/signal-boosters/ F.2 PART 90 CLASS B SIGNAL BOOSTERS Licensees and signal booster operators are required to register existing Class B signal booster installations with the FCC by November 1, 2014. After November 1, 2014, operation of an existing, unregistered Class B signal booster will be unauthorized and subject to enforcement action. Any new Class B signal booster installed after November 1, 2014 must be registered prior to operation. To encourage compliance with this new requirement, registration will be free of cost to the operator and/or licensee.[R11], [R9] FCC Part 90 Class B Signal Booster Registration & Discovery website: https://signalboosters.fcc.gov/signal-boosters/ Description There are two major elements to the MSU system; the Head End (HE) hardware and the Remote Hardware. There is one HE and multiple remotes. Each Remote consists of a single Fiber-Fed Power Amplifier chassis. The Remote chassis contains a Down Link Power Amplifier, and Up Link LNA, and a Fiber Optic Transmitter and Receiver. The Head End consists of a Fiber-Fed Power Amplifier (FFPA) chassis, a DSP Chassis, and Fiber Optic Chassis. The FFPA chassis contains an Up Link Power Amplifier, a Down Link LNA, and a Duplexer. The DSP Chassis contains one each Uplink and Down Link DSP filter cards. The Fiber Optic Chassis contains a FO Transmitter and FO Receiver for each Remote In the Uplink (UL) path, signals from portable radios are input to the Remote DAS. These signals are amplified in a Low Noise Amplifier (LNA) and converted to light by a Fiber Optic Transmitter in the Remote chassis, and transmitted to the Head End via fiber optic cable. In the Head End rack, the light from the fiber optic cable is converted back to RF by a Fiber Optic Receiver; the RF is filtered in the UL DSP Card and the filtered signal is input to the power amplifier module. The amplified RF is fed to the outside antenna via a duplexer. In the Downlink (DL) path, signals from user radios (Motorola radios that are FCC certified) are input to the Head End LNA. These signals are filtered in the DL DSP Card, combined with signals from a Motorobo repeater, converted to light by a HE Fiber Optic Transmitter, and transmitted to the FFPA via fiber optic cable. In the Remote chassis, the light from the fiber optic cable is converted back to RF by a Fiber Optic Receiver, and the RF is input to a power amplifier module. The amplified RF is input to a bandpass filter; the filtered RF feeds the Distributed Antenna System (DAS) in the building where the remote hardware is located. A Sample Port on the front panel of the FFPA allows the user to sample the signal without interrupting main line communications. The Sample Port is 40 dB below the main RF output port. The FFPA has a processor board that monitors overall chassis operation. The processor board controls the enable signal to the amplifier and monitors forward power, reverse power, current, fan status and heat sink temperature. Forward and reverse power are derived from directional couplers built into the amplifier modules. Heat sink temperature is derived from a thermistor mounted onto the heat sink and amplifier current from a sense resistor in series with the +28-volt power input. The fan has a built-in stopped rotor line which is input to the processor board. The processor board features optional remote monitoring capability via Ethernet. The Graphical User Interface (GUI) of the Network Management System (NMS) computer can display the status of the amplifier and provide control.
