when operating at full power in order to stay within the EIRP limits for the band.
4.1.1 RF Power Output Measurement
Power measurements of the TDD transmit signal were conducted with an MXA Signal analyzer per KDB 971168
D01and a gated broadband RF. The applied signal from an Flexi Zone Micro BTS CBRS FW2QMBOM1 /
2AD8UFW2QMBOM1, met the recommended characteristics as defined in 3GPP TS 36.141 V14.1.0 (2016-09)

4.1.2 Peak-to-Average Power Ratio Measurement
The Peak-to-Average Power Ratio (PAPR) of the EUT was measured per KDB 971168 D01 using the setup in
Figure 4.1.1 above and the Power Complementary Cumulative Distribution Function (CCDF) feature of
the MXA Analyzer. All modulations and all transmit ports were evaluated. The PAPR measurements were
made for every carrier in the test table for nominal 2W carriers as tabulated in Table 4.1.2.
The FCC requirement for PAPR is that the transmitter’s peak-to-average power ratio (PAPR) shall not exceed 13
dB for more than 0.1% of the time using a signal corresponding to the highest PAPR during periods of
continuous transmission. The maximum PAPR value for each measured configuration is given in Table 4.1.2.
Sample measurements are shown in the plots in Figure 4.1.2 below.
4.1.2.1 Peak-to-Average Power Ratio Results:
The maximum Peak-to-Average Power Ratio (PAPR) of the EUT measured at its antenna transmitting
terminals were measured to be 8.49 dB maximum, which is in full compliance with the requirement to
not exceed 13 dB as specified by the FCC and Industry Canada. Exact values are listed in Table 4.1.2

Section 2.1047 MEASUREMENT REQUIRED: MODULATION CHARACTERISTICS
The FW2QMBOM1 supports LTE TDD technologies. LTE utilizes Orthogonal Frequency Division Multiplexing
(OFDM) which splits the carrier frequency bandwidth into many small subcarriers. Each individual subcarrier can
be modulated with a combined QPSK + 16QAM, 64QAM or with a 256QAM digital modulation formats.
In QPSK, there are 4 possible symbol states and each symbol carries 2 bits of information. In 16QAM, there are
16 possible symbol states and each 16-QAM symbol carries 4 bits of information. In 64QAM, there are 64 possible
symbol states and each 64-QAM symbol carries 6 bits of information. While in 256QAM, there are 256 possible
symbol states and each 256-QAM symbol carries 8 bits of information. The higher-order modulations, where the
constellations become more dense, are more sensitive to poor channel conditions than the lower-order
The modulation characteristics measurement of LTE carriers measures the difference between the ideal symbols
and the measured symbols after the equalization. The measurement was performed for the 256QAM at all of the
channels as documented in table 4.2 below.
4.2.1 Modulation Characteristics Measurement
The measurements were performed at the antenna transmitting terminal of the base station system with a signal
analyzer which was calibrated in accordance with ISO 9001 process.
The test set-up diagram is given in Figure 4.2.1, where the signal analyzer used the external signals from the base
station as its trigger source and time reference. Figure 4.1.2 above shows representative screen plots of the
modulation measurement for an LTE carrier in 256QAM modulation.
4.2.2 Modulation Measurements Results:
The measured modulation characteristics of the EUT are tabulated in Table 4.2 and are in full compliance with
the FCC. Sample plots are in Figure 4.2.2 below.

4.3 Section 2.1049 MEASUREMENT REQUIRED: OCCUPIED BANDWIDTH and EDGE of
BLOCK EMISSIONS
This test measures the Occupied Bandwidth of the transmitting carrier and the Edge of-Block Emissions in the
frequency spectrum immediately outside and adjacent to the transmitting carrier(s).
The occupied bandwidth (OBW) is usually defined either as the 99% power OBW or a relative OBW. The 99%
OBW is the signal bandwidth such that, below its lower and above its upper frequency limits, the mean
power radiated or conducted are each equal to 0.5 percent of the total mean power radiated or conducted
by a given emission. The relative OBW 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 by at least X dB below the transmitter power, where the value of X is typically specified as 26.
Per KDB 971168 D01 v02, the relative OBW must be measured and reported when it is specified in the
applicable rule part; otherwise, the 99% OBW shall be measured and reported. The OBW shall be measured
when modulated by an input signal such that its amplitude and symbol rate represent the maximum rated
conditions under which the equipment is operated.
4.3.1 Results Occupied Bandwidth (Signal Bandwidth)
The measured 99% occupied bandwidth and -26 dB relative bandwidth was measured with a Agilent/Keysight
MXA signal analyzer for the 10M0F9W, 15M0F9W and 20M0F9W emission designators. The results are
tabulated in Table 4.3.1 and examples are in Figure 4.3.1 below and shows that the measured signals are within
the parameters of the emissions designator for the FCC.

4.3.2 Occupied Bandwidth-Edge of Block Emissions
Classical Occupied Bandwidth – Edge of Block Emissions is an evaluation of the transmit carrier compliance with
edge of block/edge of band requirements. This measurement documents the product’s ability to maintain
compliance with FCC Parts 2 and Part 90Z limitations on emissions outside the block of operation.
The FW2QMBOM1 LTE RF Module system supports single and multi-carrier LTE TDD technologies. This
evaluation addresses 256QAM operation with 10, 15 or 20 MHz carriers in the standard 2x2W MIMO operation.
In each test configuration the carriers were configured in either left side and right side of band channels as
appropriate. All power adjustments were performed prior to other measurements. Power was set to the total
per port maximum for the specific configuration with equal levels of power per carrier. The measurements are
The occupied bandwidth of each of the signals identified in Table 4.3.6.1 was measured using a MXA signal
analyzer and a Rohde & Schwarz ESIB-40 EMI Receiver/ Spectrum Analyzer, a PC based instrumentation controller
using TILE software and calibrated RF attenuation and coupled signal path. The measurement process meets
the requirements of ANSI C63.26 and ISO17025. The RF power level was measured and adjusted via the test
setup in Figure 4.3. The set RF output from the transmitter was reduced by calibrated broadband attenuators to
amplitudes usable by the spectrum analyzer and power meter. The attenuation factors are reflected in the
displayed values of the charts. The typical occupied bandwidth measurement displays the signal adjusted to the
reference level corresponding to the corrected RF power level for the signal bandwidth and given resolution
bandwidth (RBW). This set-point was performed as follows:
For each test the power calibration was individually verified at the transmitter antenna connection (J4) with a
power meter by using the test setup depicted in Figure 4.3. The power calibration was performed to calibrate the
spectrum analyzers power measurement against the more accurate power meter measurement. This provides a
specific reference for both the measured 100, 150 and/or 200 kHz RBW Occupied Bandwidth signal.
Plots are provided using the triggered LTE-TDD functionality of the MXA and peak detected plots using the EMC
Test Receiver. The plots complement each other and demonstrate compliance with edge of band limits.
The duality of the measurements are necessary as conducted spurious measurements are required to be
performed with the same detector functions as the RF Power/Occupied Bandwidth/Edge of Band Emissions.
Conducted spurious measurements were therefore performed over the frequency range of 10 MHz-26.5 GHz with
the N9020A MXA Signal analyzer (average detector) and 10 MHz to 37 GHz with the ESIB40 EMC Test receiver
(peak detector). Since CBRS Band 48 (3650-3700MHz) requires Conducted spurious testing to 37 GHz a second
measurement using peak detector was performed to 37 GHz
The test procedure above as applied to Figure 4.3.5, calibrates the carrier power against the Mask and accurately
places the measured occupied bandwidth carrier at the appropriate reference line. All of the plots are presented
with a sufficiently wide frequency span for the specific signals or Block of interest. This allows for ease of
comparison of the multi-carrier performance. This data was electronically recorded using the TILE software and
electronically placed in the Occupied Bandwidth Data Sheets. These sheets contain data for multiple mixed
carrier configurations for “Left Edge of Block”, and “Right Edge of Block” across the CBRS Band 48.
The Limit in 47 CFR 90.1323(a)(b) for emissions is as follows:
(a) 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 1 MHz or less, but at least one percent of the emission bandwidth of the fundamental emission of
the transmitter, provided the measured energy is integrated over a 1 MHz bandwidth.
(b) When an emission outside of the authorized bandwidth causes harmful interference, the Commission may, at its
discretion, require greater attenuation than specified in this section.
The limit described above in (a) is identical to typical limits (Part 24 & Part 27) for the first 1 MHz outside the
block as measured with a 1 MHz bandwidth.
Emissions <1 MHz outside the Block when measured with a RBW of 1% of the emissions Bandwidth
shall be attenuated by :
-{43+10log (mean power output in watts)} = -13 dBm
In order to address the limit as may be imposed for the requirement in 47CFR 90.1323 (b) we evaluated
emissions more than 1 MHz outside the band with the same increased scrutiny that is imposed on other
wireless bands. That is:
For Emissions >1 MHz outside the Block, when measured with a RBW of 1 MHz, shall be attenuated by :
-{43+10log (mean power output in watts)} = -13 dBm.
This requirement although ~ 7dB more stringent was used as the required emission limit mask shown on all OBW
plots of the LTE-TDD measurement. The average detector function was used for all MXA measurements.
4.3.4 Measurement Offset and MIMO
The spectrum analysis output plots show the peak of the LTE channel signal at the reference line that is an
appropriate number of dB below the top of Mask reference of the spectrum analyzer. For the LTE system there
is no carrier without modulation. Since the LTE signal is broadband and is 10, 15 or 20 MHz wide, all of the
measurements performed at narrower resolution bandwidths need to be evaluated with limits adjusted for the
reduction in signal energy. The following relationship was used to provide the correct level for an unmodulated
carrier vs. the modulated signal.
10*log (Resolution Bandwidth/ Transmit Bandwidth) = Signal Offset (1)
For the peak of the 10, 15 or 20 MHz LTE signal measured with a RBW of 100, 150 or 200 kHz the signal offset
For a 10 MHz carrier the Signal Offset = 10*log (100 kHz /10 MHz) = -20.00 dB
For a 15 MHz carrier the Signal Offset = 10*log (100 kHz /15 MHz) = -21.76 dB
For a 15 MHz carrier the Signal Offset = 10*log (150 kHz /15 MHz) = -21.76 dB
For a 20 MHz carrier the Signal Offset = 10*log (100 kHz /20 MHz) = -23.01 dB
For a 20 MHz carrier the Signal Offset = 10*log (200 kHz /20 MHz) = -23.01 dB
For MIMO operation in accordance with KDB 662911 D01 the limits must be adjusted per the equation:
MIMO Offset = 10LOG(n) where n= MIMO Value
For 2x MIMO = 10LOG(n)= 3.01 dB
4.3.5 Mask Parameters
The parameters for all of the limits used for these tests are detailed in Table 4.3.5, below.
Per Part 2 limits which are specified as appropriate at a given RBW can be measured and evaluated at other
RBW’s if the limit is adjusted per equation (1). Table 4.3.5, below, identifies all of the limits and calibrations line

4.3.6 Occupied Bandwidth-Edge of Block Emissions Measurement
The occupied bandwidth and out-of-band emissions measurements were made at the antenna transmitting
terminal for 10, 15 and 20 MHz carriers with QPSK+16QAM, 64QAM and 256QAM modulation. The appropriate EUTRA test model specified in 3GPP TS 36.141 V14.1.0 (2016-09) Technical Specification Group Radio Access
Network; Evolved Universal Terrestrial Radio Access (E-UTRA); Base Station (BS) conformance testing (Release
14). was used for these LTE carriers.
The measurements were performed with both a spectrum analyzer and with an MXA signal analyzer in compliance
with the procedure and requirements of ANSI C63.26. The test set-up diagram in Figure 4.3 is used for RF Power,
Modulation, Peak to Average Ratio, occupied bandwidth, out-of-band emissions and Antenna Port Conducted
Spurious Emissions.
Testing was performed for the 10, and 15 MHz carriers at the left side, center and right side of the Part 90Z
Band while measurements of the 20 MHz carriers were performed at the left side and right side of the Band.
The total carrier power level at each antenna terminal was adjusted to the maximum rated mean power 33.01
dBm (2W) for 2xMIMO configurations. This is 4W total for the two ports.
Mask parameters were as stated in Table 4.3.5. For proper evaluation of the carrier the measurement
parameters for Resolution Bandwidth and Mask Edge Offsets were followed as shown in Table 4.3.6. All of the
Mask Edge Offsets are equal to ½ of the Resolution Bandwidths used for the measurements.

4.3.6.1 Results Occupied Bandwidth-Edge of Block Emissions
The occupied bandwidth plots for operation at the left side and the right side of the band for all of the signal
bandwidths are below. The mask accurately depicts the limits for the specific blocks to determine compliance
with FCC Part 90Z. The mask limits include the appropriate considerations for 2x2W MIMO operation.
From the out-of-band emissions plots attached below, it can be seen that all the emissions are under the
required emission masks for MIMO operation.
The measurement results of the occupied bandwidth and the out-of-band emissions as documented in the
plots and Table 4.3.6.1 demonstrate the full compliance with the Rules of the Commission for the operating

Section 2.1051 MEASUREMENT REQUIRED: SPURIOUS EMISSIONS AT THE ANTENNA
This test measures the emissions of spurious signals which may come from harmonic, parasitic, intermodulation
and frequency conversion products and are outside the necessary bandwidth but excludes Edge-of-Band
4.4.1 Section 2.1051 Spurious Emissions at Antenna Terminals
Spurious Emissions at the antenna terminals were investigated per 47CFR Section 2.1057(a)(1) over the
frequency range of 10 MHz to 37 GHz which is beyond the 10th harmonic of the carrier frequency. A test
coupler which incorporates a low intermod broadband RF attenuator was used to reduce the transceiver’s
amplitude to a level usable by the spectrum analyzer. The test configuration is shown in Figure 4.4.1 which
documents the test set up used for the measurements. In this set up the complete RF test path was calibrated
over the 10 MHz-37 GHz range.
The spurious measurements were made using an automated test system and an MXA Signal Analyzer. The
automated test system consists of a Rohde & Schwarz ESIB-40 Test Receiver/ Spectrum Analyzer, a PC based
computer test controller, calibrated test hardware and a TILE  software program to acquire the test data.
These measurements are performed in compliance with ANSI C63.26 and our ISO17025 process. The
measurement meets the ANSI C63.26 requirements in paragraphs 5.2.4.4.1 and 5.7 which requires that the
number of points in the sweep be > 2 × Span/RBW. The MXA signal analyzer measurements examine the 10
MHz to 26.5 GHz range while the automated test system overlaps and extends the frequency range to
examine the 10 MHz to 37 GHz range.
Measurements were performed for all of the test configurations in Table 4.5.4 and these match the test
configurations used for Occupied Bandwidth / Edge of Band Emissions, RF Power and modulation.
4.4.2 Required Limit
The required emission limitation specified in 47CFR 24.238 1-Oct-2010 was applied to these tests. Based
upon the criterion given in Section 90Z of the Code and as developed in 4.3, the required emission limit for
emissions outside a licensee’s frequency block is:
Emissions >1 MHz outside the Block, when measured with a RBW of 1 MHz, shall be attenuated by :
In order to account for the spectral adding of identical signals from the primary and diversity ports, per KDB
662911 D01 Multiple Transmitter Output v01r01, the level needs be adjusted by 10LOG(n) where n= number of
The adjustment for n=2 is: 3.01 dB = 10LOG(2)
Therefore the limit for emissions >1 MHz outside a licensees frequency block when measured
with a RBW of 1 MHz is:
-13 dBm - 3.01 dB = -16.01 dBm for 2x MIMO
4.4.3 Operational Configuration
The modulation used in this evaluation are described in the pertinent standards documents which include 3GPP
TS 36.141 V14.1.0 (2016-09) Technical Specification Group Radio Access Network; Evolved Universal
Terrestrial Radio Access (E-UTRA); Base Station (BS) conformance testing (Release 14). The modulation is
Orthogonal Frequency Division Multiple Access (OFDMA) which is processed into an uplink IF signal. The input
data stream is divided into several parallel sub-streams of reduced data rate and each sub-stream is transmitted
on a separate orthogonal sub-carrier. For this test the sub-carriers were modulated using 256QAM.
4.4.4 Results:
Over the required frequency spectrum investigated for the EUT, no reportable out-of-block spurious emissions
were detected. The out-of-block spurious emissions in the entire spectrum investigated are under the required
reportable emission limit and are tabulated in Table 4.4.4 below. Two sets of data which represent the two
extremes of MIMO configurations tested are attached below. The measurement results demonstrate that the
subject of the application is in full compliance with the Rules of the Commission and Industry Canada.

Section 2.1053 MEASUREMENT REQUIRED: FIELD STRENGTH OF SPURIOUS
The field strength measurements of radiated spurious emissions were made in a FCC registered three meter
semi-anechoic chamber AR-5, (FCC Registration Number: 395774) NVLAP Lab Code: 100275-0 and IC (Filing
Number: 6933F-5) which is maintained by Nokia Bell Labs in Murray Hill, New Jersey.
The CBRS FW2QMBOM1 2x2W (EUT) was configured with two transmit modules in semi-anechoic chamber AR-5
in the normal field installation. The recommendations of ANSI C63.4–2014 and C63.26-2015 were followed for
EUT testing setup and cabling. The EUT was configured to operate per the E-UTRA test model specified in 3GPP
Terrestrial Radio Access (E-UTRA); Base Station (BS) conformance testing (Release 14). A depiction of the setup
is in Figure 4.5
The base station was configured into the worst case transmit configuration to transmit two 2x MIMO 10 MHz
LTE carrier with the total transmit power of 8W (2x2x2W per port/39.03 dBm). This configuration provides the
highest Power Spectral Density transmit signal for the product. All transmit ports were terminated into nonradiating 50  resistive loads. The product in the below configurations was evaluated over the 30 MHz to 37
GHz frequency range.
Table 4.5.1 EUT Configurations
Tx1, Tx2
4.5.1 Spurious Radiation and Radiated Emissions Requirements.
FCC Part 15 Class B and IC RSS-133 section 6.5.1 require emissions to be below 54.5 dBuV/m at 3m.
Title 47CFR section 90.1323 and 2.1053 contains the requirements for the levels of spurious radiation as a
function of the EIRP of the unmodulated carrier. The reference level for the unmodulated carrier is calculated as
the field produced by an isotropic radiator excited by the transmitter output power according to the following
relation taken from Reference Data for Radio Engineers, page 27-7, 6th edition, IT&T Corp.
E = (120P) ½ = [(30*P)1/2] / R
20 log (E*106) - (43 + 10 log P) = 82.23 dB V/meter
E = Field Intensity in Volts/ meter
R = Distance in meters = 3 m
P = Transmitted Power, Watts = 8 W
The field strength of radiated spurious emissions measured was determined by
E (dBV/m) = Vmeas (dBV) + Cable Loss (dB) + Antenna Factor (dBi/m).
Field strength measurements of radiated spurious emissions were made in the 3m semi-anechoic chamber, AR5. As detailed above. The recommendations of ANSI C63.4 and ANSI C63.26 were followed for EUT testing
setup, cabling, and measurement approach and procedures. All the measurement equipment used, including
antennas, was calibrated in accordance with ISO 9001 process. The EUT setup diagram is given in the Figure 4.5.
The minimum margin to the Part 90.1323 limit as measured in accordance with 2.1053 is more than 20dB.
Sample data plots are per Table 4.6.2
4.5.2 Field Strength of Spurious Radiation Results:
For the Title 47CFR section 24.238 and 2.1053 test, the field strength of any spurious radiation, measured at
3m, is required to be less than 82.23 dBV/meter. Emissions equal to or less than 62.23 dBV/meter are not
reportable and may be verified using field strength measurements with broadband antennas.
Over the out of band spectrum investigated from 10 MHz to beyond the tenth harmonic of the carrier (37GHz),
no reportable spurious emissions were detected. Additionally, from 10 MHz to beyond the tenth harmonic of
the carrier (37GHz), all non-transmit carrier emissions were below 54.5 dBV/m. This demonstrates that the
FW2QMBOM1 Flexi Zone Micro BTS CBRS / FCC ID: 2AD8UFW2QMBOM1, the subject of this application,
complies with FCC Part 15 Class B, and FCC Sections 2.1053, 90.1323 and 2.1057 of the Rules.

Section 2.1055 MEASUREMENT REQUIRED: FREQUENCY STABILITY
This measurement evaluates the frequency difference between the actual transmit carrier frequency and the
specified transmit frequency assignment. Only the portion of the transmitter system containing the frequency
determining and stabilizing circuitry need be put in an environmental chamber and subjected to the temperature
variation test per FCC Section 2.1055 and RSS-133. The unit which provides baseband signals, such as BBU
(baseband unit), can be located outside the chamber if it is a separated unit.

4.6.2 Frequency Stability Test
Frequency Stability Testing was performed on– Flexi Zone Multi-Band Outdoor (MBO) CBRS B48+WiFi with B48
CF 3675MHz. The testing was performed on the B48 CBRS MBO from 10/16-18/2017. The product was
configured per Figure 4.6.2 and tested in the T-17 Thermal chamber of the GPCL test facility located in Bldg 4,
Room 4-278, Murray Hill, NJ. Testing was witnessed by Joe Bordonaro from GPCL. The UUT was subjected to a
range of temperature from ambient to +50ºC to -30ºC and back to ambient. Frequency Stability performance
was verified by measuring Frequency Tolerance at EAC using an MXA Signal Analyzer. Frequency Tolerance is a
measurement of the difference between the actual transmit frequency and the assigned frequency (3675MHz).

Part 90Z Contention Protocol Response
This measurement evaluates the sensitivity of the products Listen Before Transmit (LBT) Contention Protocol.
The LBT response determines if the channel is occupied before transmitting on the specific channel.
The test is defined as the CBRS Cells ability to respond to a CW signal transmitting in the assigned transmit
channel. The baseline desired detection level is -85 dBm at the transmit port.
4.7.1 Part 90Z PAG Guidance on Testing Transmit (LBT) Contention Protocol Test
The FCC guidance on testing from the PAG Request, Tracking Number 349452, was as follows:
“We require a test report to demonstrate the protocol. This is usually a conducted test applying a CW interference
at the: lo mid and high parts of the occupied band above and below a couple of sample thresholds.”
4.7.2 Part 90Z Listen Before Transmit (LBT) Contention Protocol Test
The FW2QMBOM1 Flexi Zone Micro BTS CBRS was configured as shown in Figure 4.7. The EUT was configured
into a normal TDD Transmit configuration and the modulation constellation and spectrum was monitored with
the MXA. The interferer CW signal was applied with a calibrated signal path and raised in 0.1 dB increments. When
the transmit signal ceased the detection level was recorded. The signal generator output was individually
calibrated with a power meter.
Ten samples were performed at each frequency -bandwidth combination tested. Data was recorded for both 10
MHz and 20 MHz signal bandwidths. For each signal bandwidth the data consists of 20 detection responses that
were performed at left, center and right side of the 3650-3700 MHz band. There were ten samples each at each
LTE transmit frequency +/- 1 MHz.
4.7.3 Part 90Z Contention Protocol Response Results:
The data demonstrates that the FW2QMBOM1 Flexi Zone Micro BTS CBRS responded to an interferer CW signal
with an average detection level of -85.14 dBm. The summary of the trigger levels are listed in Table 4.7.2 with
complete data following below.
