A digital modulation signal generator is connected to the TX_IN port of the appropriate band of the hdHost and spectrum analyzer is connected to the corresponding EUT downlink antenna port through an attenuator, nominally 40 dB for the band under consideration. The 700 MHz (728 – 757 MHz), 850 MHz (869 – 894 MHz), PCS (1930-1995 MHz) and AWS (2110-2155 MHz) band was investigated. Measurements were performed with two types of test signals recommended by FCC KDB 935210 D05 v01r01. A quote is shown below: 3.0 Test Methods for CMRS Non-Consumer Repeater/Amplifier and Industrial Booster Devices 3.1 General Commercial Mobile Radio Services (CMRS) non-consumer RF repeaters, amplifiers, and industrial boosters shall be tested for compliance with the applicable regulatory technical requirements. Input and output power and emissions measurements must be performed using test signals that are intended to bound the typical signal space encountered within the CMRS bands. Broadband amplifiers/boosters shall be tested using a representative band-limited AWGN signal. The AWGN test signal must have a 4.1 MHz 99 % occupied bandwidth (OBW) (representative of a 5 MHz LTE channel). Narrowband test signals shall use a representative MSK modulated signal, with a Gaussian Filter of 0.3 and a data rate of 270 kbps (representative of a GSM-TDMA signal). In the tests reported here the LTE and GSM signals were used as the two test signal representatives: - LTE (5MHz channel bandwidth representing wide band signal) and - GSM (GMSK modulation with a Gaussian Filter of 0.3 and a data rate o 270kbs representing narrow band signal of about 200kHz bandwidth) 8

for the mid, lowest and highest frequency for declared bandwidths. The modulation types are described in detail in Table 1- Table 5. Figure 1-1 Conducted Emission Test Setup Diagram Vector 40dB Spectrum Signal hdHost EUT Attnuator Analyzer Generator AGC Threshold Level The measurement procedure used was KDB 935210 D05. AGC threshold level is measured by connecting a Spectrum Analyzer to the RF antenna port via an attenuator and a Signal Generator to the supporting device – hdHost RF source port. A GSM signal was generated on the center frequency of the operating band under test. The integrated Channel Power over the channel bandwidth was measured using resolution bandwidth (RBW) equals to 1% of the emission bandwidth. AGC threshold level was determined when increasing the input signal amplitude 0.5dB will no longer cause 0.5dB increase in the output signal amplitude. Out of Band Rejection The measurement procedure used was KDB 935210 D05. The Signal Generator sent CW signal sweep in the range of ±250% of the passband. So is the Spectrum Analyzer span was set to. The RBW was set to 5% of the passband. An input signal level 5dB below the AGC threshold was injected. Two traces were obtained, via Max-Hold and Clear-Write. The peak frequency in the Max-Hold trace was recorded and would be allocated for the system gain and output power measurement. Occupied Bandwidth – Input versus Output Signal Comparison The measurement procedure used was KDB 935210 D05. Occupied Bandwidth is measured by connecting a Spectrum Analyzer to the RF output connector. The required measurement RBW is 1% of the emission bandwidth. 99% energy rule was applied to measure the occupied channel bandwidth. The emission bandwidth is measured as the width of the signal between two frequency points on the channel edge, outside of which the transmission power is attenuated at least 26dB below the transmitter output power. The carrier allocated on the center frequency of the passband was investigated with input amplitude 0.5dB below the AGC threshold, for both input and output signal occupied band width. The output was then measured again with input amplitude 3dB above the AGC threshold. RF Power Output The measurement procedure used was KDB 971168 D01 Section 5.2.1. The EUT was configured to transmit continuously. RF power is measured by connecting a Spectrum Analyzer to the RF output connector. With an input power 0.5dB below and 3dB above the AGC threshold, respectively, the RF output is measured via Spectrum Analyzer’s channel 9

power function. The carrier was located at the peak frequency obtained in the out of band rejection measurement. Out of Block Emissions The measurement procedure used was KDB 935210 D05. The out of block emission was measured under two stimulus conditions. 1). Two adjacent test signal sequentially tuned to the lower and upper band edges; 2). A single test signal, sequentially tuned to the lowest and highest channels within the operating band. The intermodulation emission out of block was produced by the two carrier test signal as well. The peak emission was measured in 100kHz or 1MHz integrated bandwidth within 300kHz or 3MHz span immediate out of band, for carriers below or above 1GHz, respectively. The input power was set with two amplitude levels, i.e. 0.5dB below and 3dB above the AGC threshold level. Spurious Emissions The procedure used was ANSI/TIA-603-C: 2004. The spectrum was scanned from 9 kHz to at least the tenth harmonic of the fundamental using a spectrum analyzer. For digital modulation, the carrier is modulated to its maximum extent. The measurements were made in accordance with standard ANSI/TIA-603-C: 2004. The input power was set 0.5dB below the AGC threshold level. Simultaneous three carriers were allocated on the lowest, center and highest channels. The spurious emissions were then measured in the above range exclude the operating band ± 300kHz or ± 3MHz, in a reference bandwidth of 100kHz or 1MHz, for carriers below or above 1GHz, respectively. Intermodulation Product Spurious Emissions The procedure used was ANSI/TIA-603-C: 2004 and KDB 971168 D03. Three tones (modulated) method was used. Two tones are close to each other on the one edge and the third one is alone on the other edge of the passband. The input power to the amplifier was set to 0.5dB below the AGC threshold level by combining the three tones. The intermodulation product emissions were measured in band and spurious emissions were measured out of band. 1.10 Operational Description Dali Matrix™ is a modular, end-to-end digital RF distribution system. Matrix is implemented in two tiers: Modular Universal Base Station Interface Tray (UBiT) functioning as a headend Modular digital remote units are for indoor and outdoor deployments. A single optical fiber interface, based on the CPRI protocol, is used to connect the UBiT digital Host module with a number of hd30/37/43 remote units, in a star, daisy-chain, or hybrid star/daisy-chain configuration. The digital remote units can be installed up to 20km away from the UBiT headend. Both headend and remote units contain a digital processing section and an RF processing section. The UBit integrated headend typically interface RF signals with Base Stations via coaxial RF cables or digital baseband signal via optical fibers. 10

The remote unit hd43, which is the EUT in this test report is a quad band unit with 20 W average output power per band. Bands supported and scope of the requested license is as follows:  Lower and Upper 700 MHz Band: 27.5(c), 27.50(c), 27.53(c,g)  Cellular Band: 22.905, 22.913, 22.917  AWS-1 Band: 27.5(h), 27.50(d), 27.53(h)  Broadband PCS Band: 24.229, 24.232, 24.238 The band set that particular remote unit support is determined by the type of module that is installed in the unit, each containing frequency of operation limiting duplex filters and RF band specific filters. It is marketed for commercial cellular applications. All band support broadband 2G, 3G, and 4G waveforms. To maintain declared output power, and to prevent Power Amplifier (PA) to go into saturation condition, Automated Level Control (ALC) circuitry is implemented inside power amplifier section. The ALC circuitry monitors PA output power via built in average power detector, and if detected output power level is above threshold (set during manufacturing process), introduces attenuation in a PA lineup (PA gain reduction) that is equivalent to power difference between detected power and threshold power, hence maintains output power at level equal to ALC threshold level. The ALC attenuation range is from 0 dB to 30 dB. The ALC threshold level is set 1 dB above the declared maximum average output power, thus to +44 dBm in a case of the hd43 remote unit. Once the output power is detected above this threshold, certain attenuation will be set to draw the output down to 43dBm. 1.11 Measurement Configuration Table 1 Test Signal Applied Modulation # Carriers BW/Carrier Notation Apply to Test GSM 1 200kHz GSM-1C OBW, Pout, Out of Block Emission GSM 2 200kHz GSM-2C Out of Block Emission GSM 3 200kHz GSM-3C Spurious Emission GSM 3 200kHz GSM-3TIM Intermodulation LTE 1 5MHz LTE-1C OBW, Pout, Out of Block Emission LTE 2 5MHz LTE-2C Out of Block Emission LTE 3 5MHz LTE-3C Spurious Emission LTE 3 5MHz LTE-3TIM Intermodulation Table 2 700 MHz DL Measurement Matrix Notation Frequency (MHz) GSM-1C 728.3, 742.5, 756.7 c GSM-2C 728.3 and 728.5, or 756.5 and 756.7 a, c GSM-3C 728.2, 742.5, 756.8 11

2 AGC Threshold Level 2.1 Methodology Measurements were performed at narrow band single carrier for the center frequency within the 700 MHz (728 – 757 MHz), 850 MHz (869 – 894 MHz), PCS (1930-1995 MHz) and AWS (2110-2155 MHz) band. Tabular data is shown in section 2.3 for the all bands. The AGC threshold level is to provide the instruction of input signal amplitude for the emission in conducted measurement address in this report. The AGC threshold was determined following test method defined in FCC KDB 935210 D05 (Feb 2016) Section 3.2. 2.2 Interpretation The equipment under test (EUT) is featured automatic level control (ALC), which electronically adjusts the output power not exceed a certain maximum level. In order to align with the measurement guidance, the AGC threshold is used throughout the report, representing the ALC trip point (input power). At amplitude above the AGC threshold, an increase of 1dB in the input power will no longer cause a 1dB increase in the output signal power. 2.3 Results Table 6 AGC Threshold Levels Frequency AGC Threshold Max Output Band Modulation (MHz) (dBm) Power (dBm) 700 742.5 GSM -5.5 43.2 850 881.5 GSM -4.5 43.6 PCS 1962.5 GSM -6.5 43.7 AWS 2132.5 GSM -5.5 42.6 14

3 Out-of-band Rejection 3.1 Methodology Measurements were performed at CW signal sweep in a frequency range of 5 times the operating bandwidth centered at the operating band. The operating bands are 700 MHz (728 – 757 MHz), 850 MHz (869 – 894 MHz), PCS (1930-1995 MHz) and AWS (2110-2155 MHz) on the downlink – transmitting direction - where the air interface exists. The measurement procedure follows the KDB 935210 D05 Section 3.3. The input power level was set 5dB lower than the AGC threshold level, so that no output suppression occurred in any of the EUT bands. 20dB down bandwidth was measured compared to the peak power in-band. The peak power frequency was recorded and would be used to check the EUT output power. 3.2 Results – Frequency Responses Figure 3-1 Frequency Response of EUT Band 700 Band 850 Band PCS Band AWS Table 7 AGC Threshold Levels 15

Measurement method was following KDB 935210 D05 Section 3.4. Occupied bandwidth (OBW) of input and output signal is shown in Figure 4-1 and Figure 4-2 side by side for the four operating bands. The output OBW was tested under two input conditions: - Nominal: with input 0.5dB below AGC threshold - AGC: with input 3dB above AGC threshold A brief summary of applicable FCC specifications is listed in the table below. 2.1049 Measurements required: Occupied bandwidth. The occupied bandwidth, that is the frequency bandwidth such that, below its lower and above its upper frequency limits, the mean powers radiated are each equal to 0.5 percent of the total mean power radiated by a given emission shall be measured 4.2 Results – Occupied Bandwidth Figure 4-1 Screen Captures of OBW Measurement – Input and Output Narrow Band Signal Input Signal Output Signal – Nominal Output Signal - AGC Band 700 16

5 Output Power 5.1 Methodology Measurements were performed at narrow band and wide band signal for the peak output power within the 700 MHz (728 – 757 MHz), 850 MHz (869 – 894 MHz), PCS (1930-1995 MHz) and AWS (2110-2155 MHz) band. Measurement method was following KDB 935210 D05 Section 3.4 and KDB 971168 D01 Section 5.2.1. Average output power is shown in the Figure 5-1and Figure 5-2 for the four operating bands. The output power was tested under two input conditions: - Nominal: with input 0.5dB below AGC threshold - AGC: with input 3dB above AGC threshold A brief summary of applicable FCC specifications is listed in the table below. 2.1046 Measurements required: RF power output. (a) For transmitters other than single sideband, independent sideband and controlled carrier radiotelephone, power output shall be measured at the RF output terminals when the transmitter is adjusted in accordance with the tune-up procedure to give the values of current and voltage on the circuit elements specified in § 2.1033(c)(8). The electrical characteristics of the radio frequency load attached to the output terminals when this test is made shall be stated. 5.2 Interpretation The peak output power was allocated in the previous out-of-band rejection test. In the case that a full channel cannot accommodate in-band by setting the carrier frequency to the exact peak frequency, the test carrier location was moved inward to the first applicable channel. 5.3 Results Figure 5-1 Screen Captures of Power Measurement – Narrow Band Signal Output Signal – Nominal Output Signal - AGC Band 700 19

(c) (1) For operations in the 746-758 MHz band and the 776-788 MHz band, the power of any emission outside the licensee's frequency band(s) of operation shall be attenuated below the transmitter power (P) within the licensed band(s) of operation, measured in watts, in accordance with the following: On any frequency outside the 746-758 MHz band, the power of any emission shall be attenuated outside the band below the transmitter power (P) by at least 43 + 10 log (P) dB (g)For operations in the 600 MHz band and the 698-746 MHz band, the power of any emission outside a licensee's frequency band(s) of operation shall be attenuated below the transmitter power (P) within the licensed band(s) of operation, measured in watts, by at least 43 + 10 log (P) dB. Compliance with this provision is based on the use of measurement instrumentation employing a resolution bandwidth of 100 kilohertz or greater. However, in the 100 kilohertz bands immediately outside and adjacent to a licensee's frequency block, a resolution bandwidth of at least 30 kHz may be employed. (h) For operations in the 1710–1755 MHz and 2110–2155 MHz bands, the power of any emission outside a licensee’s frequency block shall be attenuated below the transmitter power (P) by at least 43 + 10 log10 (P) dB. (1) Compliance with this provision is based on the use of measurement instrumentation employing a resolution bandwidth of 1 megahertz or greater. However, in the 1 megahertz bands immediately outside and adjacent to the licensee’s frequency block, a resolution bandwidth of at least one percent of the emission bandwidth of the fundamental emission of the transmitter may be employed. The emission bandwidth is defined as the width of the signal between two points, one below the carrier center frequency and one above the carrier center frequency, outside of which all emissions are attenuated at least 26 dB below the transmitter power. 22.917 Emission limits. (a) Out of band emissions. The power of any emission outside of the authorized operating frequency ranges must be attenuated below the transmitting power (P) by a factor of at least 43 + 10 log(P) dB. 24.238 Emission limitations for Broadband PCS equipment. (a) Out of band emissions. The power of any emission outside of the authorized operating frequency ranges must be attenuated below the transmitting power (P) by a factor of at least 43 + 10 log(P) dB. The limit is = -13 dBm. 6.2 Out-of-band Emission 6.2.1 Measurement Configuration Measurements were performed at narrow band and wide band signal at the lower and upper edge within the 700 MHz (728 – 757 MHz), 850 MHz (869 – 894 MHz), PCS (1930-1995 MHz) and AWS (2110-2155 MHz) band. 23

Tests were repeated for single carrier and adjacent dual carriers, as defined in 3GPP, on first and last channel in the operating bands. For each type of signal applied, tests were again repeated under two input conditions: - Nominal: with input 0.5dB below AGC threshold - AGC: with input 3dB above AGC threshold The out-of-band emission was measured within specified frequency range at the edge of the authorized frequency band, 300kHz range for the frequency band below 1GHz and 3MHz range for the one above 1GHz. Normally the reference band width (RBW) in spurious emission measurement was specified to 100kHz for the frequency range below 1GHz and 1MHz for the frequency range above 1GHz. A relaxation of RBW is allowed to be applied to out-of-band emission measurement. KDB 971168 D01 page14: This is often implemented by permitting the use of a narrower RBW (typically limited to a minimum RBW of 1% of the OBW) for measuring the out-of-band emissions without a requirement to integrate the result over the full reference bandwidth. Beyond the specified frequency range in which this relaxation is permitted, it is also typically acceptable to use a narrower RBW (again limited to a minimum of 1% of OBW) in order to increase accuracy, but the measurement result must subsequently be integrated over the full reference bandwidth. 6.2.2 Results The immediate out-of-band emission measurement is shown in the Figure 6-1, Figure 6-2, Figure 6-3 and Figure 6-4 for the four operating bands. Conclusion: The peak out-of-band emission caused by any of the following combination – narrow band signal vs wide band signal, single carrier vs dual carriers, and nominal input vs input above AGC threshold - is below -13dBm limit.
