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/ 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 purpose of this document is to provide background information about where the firmware updates originate and who can load the updated firmware onto the processor board. Revision of Firmware The Model 1464 Head End System was designed and built by Applied Micro Design, Inc. (AMDI). Design includes hardware design, embedded firmware, and the software Graphic User Interface) GUI. The firmware is proprietary code; no one outside AMDI has access to the source code, and no one outside AMDI can modify or change this code. The ability to update the firmware was added for the convenience of the customer. It allows the customer to change external interfaces (RACS, Ethernet, and LED’s) as system requirements change. No changes will be made that can affect any of the RF parameters of the amplifier. Changes will be tested in-house before being sent to the customer. The firmware runs under control of a bootloader that transfers the firmware from a device drive to the processor board using an Ethernet interface. The bootloader is proprietary code that was also written by AMDI. Uploading Revised Firmware Before uploading new firmware to the amplifier, the user must first enter a valid Userid and Password. This was done to prevent unauthorized personnel from making any changes to the system operation. The system is shipped with a default Userid and Password; both can be changed by the system administrator.

Office of Engineering and Technology Inquiry on 07/14/2015 : Inquiry: We have a client that is trying to certify a Class B industrial booster. The system is to be used in one application with pre-defined input and output levels. The input for the Downlink is from a base station several miles from the building and fed to the building via fiber optics. In the building, the Fiber is terminated into a Fiber to RF converter (non-certified) and delivers a -10dBm/carrier input level to the booster. The booster provides band filtering and amplification to +20dBm/carrier and this signal is fed into a DAS made up of lossy coax with a gain of -70dBi. The Uplink side of the system is strictly a receiver. Signals are taken from the DAS and amplified. The output of the Uplink connects to a RF to Fiber converter and the signal is sent via fiber to the base station. The Uplink path is never broadcast. Paragraph 4.2 of Section 4.0 TEST METHODS FOR PLMRS/PSRS REPEATER/AMPLIFIER AND INDUSTRIAL BOOSTER DEVICES of the KDB “MEASUREMENTS GUIDANCE FOR INDUSTRIAL AND NON-CONSUMER SIGNAL BOOSTER, REPEATER, AND AMPLIFIER DEVICES” dated June 5, 2015 specifies that the 2 booster’s AGC threshold be measured using the procedure of paragraph 3.2, which has the lab determine the compression point then perform the remaining test slightly below this level although if you consider the notes at the bottom of section 3.2: “In the case of fiber-optic distribution systems, the RF input port of the equipment under test refers to the RF input of the supporting equipment RF to optical convertor. Devices intended to be directly connected to an RF source only need to be evaluated for any over-the-air transmit paths.” This appears to be referring to setting the level of the uplink, not the downlink input. In the case of my clients system, the only over-the-air transmission his system is responsible for would be the downlink path to the DAS. 3 As this is a Class b industrial booster which is professionally installed and operated: 1) Can we perform the test of the downlink system at the designed input level of -10dBm? FCC response on 07/18/2015 Based on info at hand, the test node / method seems acceptable. Please include clear block diagram of end-to-end RF paths in the filing, labeling all relevant nodes and components. At present B9B 90.219 Class B boosters are still on the PAG list; please provide records of this KDB along with submission to TCB for part of their review and TCB PAG submission.

Testing supporting this evaluation was performed at Washington Laboratories, Ltd, 7560 Lindbergh Drive, Gaithersburg, MD 20879. Washington Laboratories, Ltd. has been accepted as an EMC Conformity Assessment Body (CAB) under the United States/European Union Memorandum of Agreement. Washington Laboratories, Ltd. is accredited with ACLASS under Testing Certificate AT-1448. 2 Requirements Three different categories of transmitters are defined by the FCC in OET Bulletin 65. These categories are fixed installation, mobile, and portable. Additionally, the FCC categorizes the use of the devices based on the user’s awareness and the ability to exercise control over his or her exposure. The two categories are defined as Occupational/Controlled Exposure and General Population/Uncontrolled Exposure. 2.1 Transmitter Categories 2.1.1 Fixed Installations A fixed location means that the device, including its antenna, is physically secured at a permanent location and is not able to be easily moved to another location. Additionally, distance to humans from the antenna is maintained to at least 2 meters. 2.1.2 Mobile Devices A mobile device is defined as a transmitting device designed to be used in other than fixed locations and to be generally used in such a way that a separation distance of at least 20 centimeters is normally maintained between the transmitter's radiating structures and the body of the user or nearby persons. Transmitters designed to be used by consumers or workers that can be easily re-located, such as a wireless modem operating in a laptop computer, are considered mobile devices if they meet the 20 centimeter separation requirement. The FCC rules for evaluating mobile devices for RF compliance are found in 47 CFR §2.1091. 2.1.3 Portable Devices A portable device is defined as a transmitting device designed to be used so that the radiating structure(s) of the device is/are within 20 centimeters of the body of the user. Portable device requirements are found in Section 2.1093 of the FCC's Rules (47 CFR§2.1093). 2.2 Exposure Categories The limits for exposure are determined by the type of situation the individual is…
