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. This is a Class B Booster.Notes, Cautions, and Warnings!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/Downloaded from www.Manualslib.com manuals search engine

Introduction There are three major components to the Tower-4 system; the Head-End hardware, the Distributed Antenna System (DAS) hardware, and the Site-Wide Network (SWN). Signals from the SWN are input to the Downlink (DL) Head-End (HE) hardware. These signals are filtered and amplified by the HE DL, and fed into the DAS. Signals from the DAS are input to the Uplink (UL) HE hardware. These signals are filtered and amplified by the HE UL, and fed into the SWN. There are two equipment rooms in Tower-4, and each equipment room has an Uplink and Downlink rack. One each of these racks (one UL and one DL) will be tested. The Downlink Rack contains three DSP Card Cages, two Dual Amplifiers, one Single Amplifier, and one CBC chassis. The signals are combined in the CBC chassis and fed to the DAS. The Uplink Rack contains three DSP Card Cages and one CBC chassis. Signals from the DAS are input to the CBC chassis. The UL and DL Channel Cards are the same design. They are FPGA-based designs, programmed essentially as active digital filters. The cards have a standard line-up; Analog-to-Digital Conversion, Digital Demodulation to baseband, digital filtering in the FPGA, Digital Modulation back to the original carrier frequency, and Digital-to-Analog conversion. The DSP Channel Cards can be programmed for multiple filters to process multi-carrier signals. Head-End Downlink Group There are eleven SWN windows (seven 400 MHz and four 800 MHz) input to the HE channel cards. Each window is input to a separate card; each card is set for one wide-band filter to pass multi-carrier signals, and is set for a specified gain. Wide-band filters for the DL are specified to achieve the required Group or Propagation Delay of 10 μs.The Site Wide Network (SDN Demarc) provides a constant level of -10 dBm per carrier into each Downlink Channel Card.The outputs of the Downlink Channel Cards are input to power amplifiers, either directly or via a combiner. Window groupings to the power amplifiers are shown on the system block diagrams. The gain of the Downlink Channel Cards are set to have an output of +20 dBm per carrier (100 mW) at the output of the power amplifiers, with -10 dBm per carrier at the input of the Downlink Channel Cards. The 800 MHz Downlink Channel Cards are set to have an output of +22 dBm at the output of the power amplifiers.The power amplifiers are very linear and can handle multiple carriers. The ALC (Automatic Level Control) of each amplifier is set to provide a maximum of +37 dBm (5W).The outputs of the 400 MHz and 800 MHz power amplifiers are combined through combiners and low-loss CBC (Cross-Band Couplers). The output of the CBC is the connection into the DAS. Head-End Uplink Group There are eleven windows (seven 400 MHz and four 800 MHz) input to the UL channel cards from the DAS. Each window is input to a separate card; each card is set for one or more narrow-band filter to pass multi-carrier signals. Narrow-band filters for the UL are specified to achieve the required Group or Propagation Delay of 25 μs. A group of frequencies (window grouping) is assigned to one Uplink Channel Card. The signals coming from the DAS are amplified with an LNA (low-noise amplifier) and distributed to the Uplink Channel Cards using a CBC and splitters. The Uplink Channel Cards will receive multi-carrier signals in the range of -83 dBm to -33 dBm per carrier. Each Uplink Channel Card uses AGC (Automatic Gain Control) to maintain an output level of -33 dBm. The Site Wide Network or SDN Demarc requires no more than -33 dBm per carrier.Downloaded from www.Manualslib.com manuals search engine
