1 Introduction

The equipment under test (EUT) is Netgear 5G MHS Travel Router (FCC ID: PY319100441), it
contains the Qualcomm® SM8150 modem supporting 2G/3G/4G technologies and SDX50
modem supporting mmW 5G NR bands. Both of these modems are enabled with Qualcomm
Smart Transmit feature to control and manage transmitting power in real time and to ensure at all
times the time-averaged RF exposure is in compliance with the FCC requirement.
This purpose of the Part 2 report is to demonstrate the EUT complies with FCC RF exposure
requirement under Tx varying transmission scenarios, thereby validity of Qualcomm Smart
Transmit feature for FCC equipment authorization of Netgear 5G MHS Travel Router (FCC ID:
PY319100441).
The Plimit and input.power.limit used in this Part 2 report is determined and listed in Part 0 report.
Refer to Compliance summary report for EUT description and terminology used in this report.

Netgear 5G MHS Travel Router (FCC ID: PY319100441) RF Exposure Compliance Test Report (Part 2: Test Under Dynamic
Transmission Scenario) Tx Varying Transmission Test Cases and Test Proposal

2 Tx Varying Transmission Test Cases and
Test Proposal

In general, to validate power enforcement by Smart Transmit and demonstrate the compliance in
Tx varying transmission conditions, the following test cases are proposed and agreed by FCC:
1. During a time-varying Tx power transmission: To prove that the Smart Transmit algorithm
accounts for Tx power variations in time accurately.
2. During a call disconnect and reestablish scenario in 2G/3G/4G technology: To prove that the
Smart Transmit algorithm accounts for history of past Tx power transmissions accurately.
3. During technology/band handover within 2G/3G/4G technology: To prove that the Smart
Transmit algorithm functions correctly during transitions in technology/band.
4. During antenna (or beam) switch: To prove that the Smart Transmit algorithm functions
correctly during transitions in antenna (such as AsDiv scenario) or beams (different antenna
array configurations).
5. SAR vs. PD exposure switching during sub-6+mmW transmission: To prove that the Smart
Transmit algorithm functions correctly and ensures total RF exposure compliance during
transitions in SAR only exposure, SAR+PD exposure, and PD only exposure scenarios.
As shown in Table 4-1 of Section 4.1 Part 1 report, since maximum time-averaged power level
Plimit ≥ Pmax (maximum RF tune-up output power) for all sub-6 radios supported for this EUT, the
power limiting will not be enforced from Smart Transmit when only sub-6 radio is active. Hence,
the validation for sub-6 radio is not required for this EUT when only sub-6 radio is active.
The test case 1, 4 and 5 are performed in this Part 2 report for 5G mmW NR band 260 with LTE
B2 as anchor.
For a SAR-and PD-characterized wireless device, RF exposure is proportional to the Tx power.
Thus, algorithm validation in Part 2 can be effectively performed through conducted (for f <
6GHz) and radiated (for f ≥ 6GHz) power measurement. Therefore, the validation is done in
power measurement setup for test cases 1, 4 and 5.
To add confidence in the algorithm validation, the time-averaged SAR and PD measurements are
also performed, but they are only performed for test case 1 to avoid the complexity in SAR/PD
measurement.
The strategy for testing in Tx varying transmission condition is outlined as follows:
■ Demonstrate the total RF exposure averaged over FCC defined time windows does not
exceed FCC’s SAR and PD limits, through time-averaged power measurements
□ Measure conducted Tx power (for f < 6GHz) versus time, and radiated Tx power (EIRP
for f > 6GHz) versus time.
□ Convert it into RF exposure and divide by respective FCC limits to get normalized
exposure versus time.
□ Perform running time-averaging over FCC defined time windows.

defined by FCC.

■ Demonstrate the total RF exposure averaged over FCC defined time windows does not

mentioned earlier, this measurement is performed for test case 1 only.

case 1 at all times.

3 PD Time Averaging Validation Test
Procedures

This section provides the test plan and test procedures for validating Qualcomm Smart Transmit
algorithm for mmW transmission. For this EUT, millimeter wave (mmW) transmission is only in
non-standalone mode, i.e., it requires a sub-6 LTE link as anchor.

3.1 Test sequence for validation in mmW NR transmission
In 5G mmW NR transmission, the test sequence for validation is with the callbox requesting EUT
to transmit in 5G mmW NR at maximum power all the time.

3.2 Test configuration selection criteria for validating smart
transmit algorithm

3.2.1 Test configuration selection for time-varying Tx power
transmission
The Smart Transmit time averaging algorithm operation is independent of bands, modes,
channels, and antenna configurations (beams) for a given technology. Hence, validation of Smart
Transmit in any one band/mode/channel/beam per technology is sufficient.

3.2.2 Test configuration selection for change in antenna configuration
(beam)
The Smart Transmit time averaging algorithm operation is independent of bands, modes,
channels, and antenna configurations (beams) for a given technology. Hence, validation of Smart
Transmit with beam switch between any two beams is sufficient.

3.2.3 Test configuration selection for SAR vs. PD exposure switch
during transmission
The Smart Transmit time averaging algorithm operation is independent of the nature of exposure
(SAR vs. PD) and ensures total time-averaged RF exposure compliance. Hence, validation of
Smart Transmit in any one band/mode/channel/beam for mmW + sub-6 (LTE) transmission is
sufficient, where the exposure varies among SAR dominant scenario, SAR+PD scenario, and PD
dominant scenario.

Transmission Scenario) PD Time Averaging Validation Test Procedures
3.3 Test procedures for radiated power measurements
The test procedures for performing conducted power measurement (for f < 6GHz) and radiated
power measurement (for f > 6GHz) for LTE + mmW transmission to validate Smart Transmit
time averaging algorithm in the various transmission scenarios are described in this section.

3.3.1 Time-varying Tx power scenario
The purpose of the test is to demonstrate the effectiveness of power limiting enforcement and that
the time-averaged transmit power when converted into RF exposure values does not exceed the
FCC limit at all times (see Eq. (1a), (1b) & (1c) in Section 2).

Test procedure:
1. Measure conducted Tx power corresponding to Plimit for LTE in selected band, and measure
radiated Tx power corresponding to input.power.limit in desired mmW band/channel/beam.
Test condition to measure conducted Plimit and radiated input.power.limit is:
2. Measure radiated power corresponding to mmW input.power.limit by setting up the EUT to
transmit in desired band/channel/beam at input.power.limit in Factory Test Mode (FTM).
This test is performed in a calibrated anechoic chamber. Rotate the EUT to obtain maximum
radiated Tx power, keep the EUT in this position and do not disturb the position of the EUT
inside the anechoic chamber for the rest of this test.
3. Reset EUT to place in online mode and establish radio link in LTE, measure conducted Tx
power corresponding to LTE Plimit with Smart Transmit enabled and Reserve_power_margin
set to 0 dB, callbox set to request maximum power.
4. Set Reserve_power_margin to actual value (i.e., intended value) and reset power on EUT to
enable Smart Transmit. With EUT setup for a mmW NR call in the desired/selected LTE
band and mmW NR band/beam, perform the following steps:
a. Establish LTE (sub-6) and mmW NR connection. As soon as the mmW connection is
established, immediately request all-down bits on LTE link. With callbox requesting
EUT to transmit at maximum mmW power to test predominantly PD exposure scenario
(as SAR exposure is less when LTE transmits at low power).
b. After 120s, request LTE to go all-up bits for at least 100s. SAR exposure is dominant.
There are two scenarios:
i If Plimit < Pmax, then the RF exposure margin (to mmW NR) gradually run out of (due
to high SAR exposure), the 5G NR mmW transmission power should be gradually
reduced accordingly and eventually seized when LTE goes to Preserve level.
ii If Plimit ≥ Pmax, then the 5G NR mmW transmission averaged power should gradually
reduce but the mmW NR connection can sustain all the time (assuming TxAGC
uncertainty = 0dB).
c. Record the conducted Tx power of LTE and radiated Tx power of mmW NR for the full
duration of this test of ~ 300s or longer.
5. Once the measurement is done, extract instantaneous Tx power versus time for both LTE and
mmW links. Convert the conducted Tx power for LTE into 1gSAR value using Eq. (1a) and
Plimit measured in Step 1.b, and then divide by FCC limit of 1.6 W/kg for 1gSAR to obtain
instantaneous normalized 1gSAR versus time. Perform 100s running average to determine
normalized 100s-averaged 1gSAR versus time as illustrated in Figure 5-1.

band/channel/beam. Test condition to measure conducted Plimit and radiated input.power.limit
is:
2. Measure radiated power corresponding to mmW input.power.limit by setting up the EUT to
transmit in desired band/channel/beam at input.power.limit in FTM. This test is performed in
a calibrated anechoic chamber. Rotate the EUT to obtain maximum radiated Tx power, keep
the EUT in this position and do not disturb the position of the EUT inside the anechoic
chamber for the rest of this test.
3. Reset EUT to place in online mode and establish radio link in LTE, measure conducted Tx
power corresponding to LTE Plimit with Smart Transmit enabled and Reserve_power_margin
set to 0 dB, callbox set to request maximum power.
4. Set Reserve_power_margin to actual value (intended value) and reset power in EUT, With
EUT setup for LTE (sub-6) + mmW NR call, perform the following steps:
5. Establish LTE (sub-6) and mmW NR connection with callbox.
6. As soon as the mmW connection is established, immediately request all-down bits on LTE
link. Continue LTE (all-down bits) + mmW transmission for more than 100s duration to test
predominantly PD exposure scenario (as SAR exposure is negligible from all-down bits in
LTE).
7. After 120s, request LTE to go all-up bits, mmW transmission should gradually run out of RF
exposure margin if Plimit < Pmax and seize mmW transmission (SAR only scenario); or mmW
transmission should gradually reduce in Tx power if Plimit > Pmax and will sustain the
connection, in this case there will be no SAR exposure only scenario when the EUT is in EN-
DC mode.
8. After 75s, request LTE to go all-down bits, mmW transmission should start getting RF
exposure margin and gradually transmit at high averaged power again.
9. Record the conducted Tx power of LTE and radiated Tx power of mmW for the entire
duration of this test of ~300s or longer.
10. Once the measurement is done, extract instantaneous Tx power versus time for both LTE and
mmW links. Convert the conducted Tx power for LTE into 1gSAR value using Eq. (1a) and
Plimit measured in Step 1.b, and then divide by FCC limit of 1.6 W/kg for 1gSAR to obtain
instantaneous normalized 1gSAR versus time. Perform 100s running average to determine
normalized 100s-averaged 1gSAR versus time.

NOTE: In Eq.(1a), instantaneous Tx power is converted into instantaneous 1gSAR value by applying the
corresponding worst-case 1gSAR value measured at Plimit for the technology/band/antenna/DSI
reported in Part 1 report.

11. Similarly, convert the radiated Tx power for mmW NR into 4cm2PD value using Eq. (1b) and
the radiated Tx power limit (i.e., radiated Tx power measured at input.power.limit) measured
in Step 1.a, then divide this by FCC 4cm2PD limit of 10W/m2 to obtain instantaneous
normalized 4cm2PD versus time. Perform 4s running average to determine normalized 4s-
averaged 4cm2PD versus time.

NOTE: In Eq.(2b), instantaneous radiated Tx power is converted into instantaneous 4cm2PD by applying
the corresponding worst-case 4cm2PD value measured at input.power.limit for the selected
band/beam in Part 1 report.

12. Make one plot containing: (a) instantaneous conducted Tx power for LTE versus time, (b)
computed 100s-averaged conducted Tx power for LTE versus time, (c) instantaneous radiated
Tx power for mmW versus time, as measured in Step 2, (d) computed 4s-averaged radiated
Tx power for mmW versus time, and (e) time-averaged conducted and radiated power limits
for LTE and mmW radio, respectively.
13. Make another plot containing: (a) computed normalized 100s-averaged 1gSAR versus time
determined in Step 3, (b) computed normalized 4s-averaged 4cm2PD versus time determined
in Step 4, and (c) corresponding total normalized time-averaged RF exposure (sum of steps
(6.a) and (6.b)) versus time.
The validation criteria is, at all times, the total normalized time-averaged RF exposure versus
time determined in Step 6.c shall not exceed the normalized limit of 1.0 of FCC requirement (i.e.,
Eq. (1c)).

3.3.3 Change in antenna configuration (beam)
This test is to demonstrate the correct power control by Smart Transmit during changes in
antenna configuration (beam). Since the input.power.limit varies with beam, the Eq. (1a), (1b)
and (1c) in Section 2 are written as below for transmission scenario having change in beam,

NOTE: If Plimit ≥ Pmax, 1gSAR measured at Plimit shall be replaced with 1gSAR measured at Pmax.

and measure radiated Tx power corresponding to input.power.limit in desired mmW

band/channel/beam. Test condition to measure conducted Plimit and radiated input.power.limit
is:
2. Measure radiated power corresponding to mmW input.power.limit by setting up the EUT to
transmit in desired band/channel for beam 1 at input.power.limit in FTM. Do not disturb the
position of the EUT inside the anechoic chamber for the rest of this test. Repeat this Step 1.a
for beam 2.
3. Reset EUT to place in online mode and establish radio link in LTE, measure conducted Tx
power corresponding to LTE Plimit with Smart Transmit enabled and Reserve_power_margin
set to 0 dB, callbox set to request maximum power.
4. Set Reserve_power_margin to actual value (intended value) and reset power in EUT, With
EUT setup for LTE (sub-6) + mmW connection, perform the following steps:
5. Establish LTE (sub-6) and mmW NR connection in beam1. As soon as the mmW connection
is established, immediately request all-down bits on LTE link with the callbox requesting
EUT to transmit at maximum mmW power.
6. After beam 1 transmits for at least 20s, request the EUT to change from beam 1 to beam 2,
and continue transmitting with beam 2 for at least 20s.
7. Record the conducted Tx power of LTE and radiated Tx power of mmW for the entire
duration of this test.
8. Once the measurement is done, extract instantaneous Tx power versus time for both LTE and
mmW links. Convert the conducted Tx power for LTE into 1gSAR value using the similar
approach described in Step 3 of Section 3.3.2. Perform 100s running average to determine
normalized 100s-averaged 1gSAR versus time.
9. Similarly, convert the radiated Tx power for mmW NR into 4cm2PD value using Eq. (3b),
(3c) and the radiated Tx power limits (i.e., radiated Tx power measured at input.power.limit)
measured in Step 1.a for beam 1 and beam 2, respectively, and then divide the resulted PD
values by FCC 4cm2PD limit of 10W/m2 to obtain instantaneous normalized 4cm2PD versus
time for beam 1 and beam 2. Perform 4s running average to determine normalized 4s-
averaged 4cm2PD versus time.

NOTE: In Eq.(3b) and (3c), instantaneous radiated Tx power of beam 1 and beam 2 is converted into
instantaneous 4cm2PD by applying the corresponding worst-case 4cm2PD value measured at the
input.power.limit of beam 1 and beam 2 in Part 1 report.

10. Since the measured radiated powers for beam1 and beam2 in Step 1.a were performed at an
arbitrary rotation of EUT in anechoic chamber, repeat Step 1.a of this procedure by rotating
the EUT to determine maximum radiated power at input.power.limit in FTM mode for both

The validation criteria is, at all times, the total normalized time-averaged RF exposure versus
time determined in Step 6.c shall not exceed the normalized limit of 1.0 of FCC requirement (i.e.,
(3d)).

3.4 Test procedure for PD measurements
The following steps are used to perform the validation through PD measurement for test case 1
described in Section 2:
1. Place the EUT on the DASY platform to perform PD measurement in the worst-case
position/surface for the selected mmW band/beam/DSI. In PD measurement, the callbox is
set to request maximum mmW Tx power from EUT all the time. Hence, “path loss”
calibration between callbox antenna and EUT is not needed in this test.
2. Time averaging algorithm validation:
a. Measure conducted Tx power corresponding to Plimit for LTE in selected
band/channel/DSI, and measure point E-field corresponding to input.power.limit in
desired mmW band/channel/beam. Test condition to measure conducted Plimit and PD
(i.e., E-field) at input.power.limit is:
3. Measure conducted Tx power corresponding to LTE Plimit with Smart Transmit enabled and
Reserve_power_margin set to 0 dB, callbox set to request maximum power.
4. Measure point E-field at peak location of fast area scan corresponding to input.power.limit by
setting up the EUT to transmit in desired mmW band/channel/beam at input.power.limit in
FTM Mode. Do not disturb the position of EUT and mmW DASY probe.
a. Set Reserve_power_margin to actual value (i.e., intended value) and reset power on EUT,
place EUT in online mode. With EUT setup for LTE (sub-6) + mmW call, as soon as the
mmW connection is established, request all-down bits on LTE link. Continue LTE (all-
down bits) + mmW transmission for more than 100s duration to test predominantly PD
exposure scenario. After 120s, request LTE to go all-up bits, mmW transmission should
gradually reduce. Record the conducted Tx power of LTE and point relative E-field (i.e.,
[𝑝𝑜𝑖𝑛𝑡𝐸(𝑡)]2
ratio of [𝑝𝑜𝑖𝑛𝑡𝐸_𝑖𝑛𝑝𝑢𝑡.𝑝𝑜𝑤𝑒𝑟.𝑙𝑖𝑚𝑖𝑡]2) of mmW at peak location identified in Step 2.a.ii for
the entire duration of this test of ~300s.
b. Once the measurement is done, extract instantaneous Tx power versus time for LTE and
[𝑝𝑜𝑖𝑛𝑡𝐸(𝑡)]2
[𝑝𝑜𝑖𝑛𝑡𝐸_𝑖𝑛𝑝𝑢𝑡.𝑝𝑜𝑤𝑒𝑟.𝑙𝑖𝑚𝑖𝑡]2
versus time from DASY system for mmW. Convert the
conducted Tx power for LTE into 1gSAR value using Eq. (2a) and Plimit measured in Step
2.a.i, and then divide this by FCC limit of 1.6 W/kg for 1gSAR to obtain instantaneous
normalized 1gSAR versus time. Perform 100s running average to determine normalized
100s-averaged 1gSAR versus time.

NOTE: In Eq.(2a), instantaneous Tx power is converted into instantaneous 1gSAR value by applying the
worst-case 1gSAR value measured at Plimit for the corresponding technology/band reported in Part
1 report.

[𝑝𝑜𝑖𝑛𝑡𝐸(𝑡)]2
c. Similarly, convert the [𝑝𝑜𝑖𝑛𝑡𝐸_𝑖𝑛𝑝𝑢𝑡.𝑝𝑜𝑤𝑒𝑟.𝑙𝑖𝑚𝑖𝑡]2 for mmW into 4cm2PD value using Eq.
(2b) and radiated power limit measured in Step 2.a.ii, and then divide this by FCC

Perform 4s running average to determine normalized 4s-averaged 4cm2PD versus time.

NOTE: In Eq.(2b), the instantaneous relative E-field (i.e., ratio of [𝑝𝑜𝑖𝑛𝑡𝐸_𝑖𝑛𝑝𝑢𝑡.𝑝𝑜𝑤𝑒𝑟.𝑙𝑖𝑚𝑖𝑡]2
) is converted
into instantaneous 4cm2PD by applying the corresponding worst-case 4cm2PD value measured at
the input.power.limit of beam 1 and beam 2 in Part 1 report.

d. Make one plot containing: (i) computed normalized 100s-averaged 1gSAR versus time
obtained in Step 2.c, (ii) computed normalized 4s-averaged 4cm2PD versus time
determined in Step 2.d, and (iii) corresponding total normalized time-averaged RF
exposure (sum of steps (2.e.i) and (2.e.ii)) versus time.
The validation criteria is, at all times, the total normalized time-averaged RF exposure versus
time determined in Step 2.e.iii shall not exceed the normalized limit of 1.0 of FCC
requirement (i.e., Eq. (2c)).

5 Radiated Power Test Results for mmW
Smart Transmit Algorithm Validation

5.1 WWAN (sub-6) transmission
As discussed in Section 2, since maximum time-averaged power level Plimit ≥ Pmax (maximum RF
tune-up output power) for all supported 4G WWAN technologies/bands/DSI for this EUT, there
is no power limiting required if only 4G radio is active. Hence, the Tx varying transmission
scenario tests listed in Section 2 are performed for EN-DC, i.e., mmW NR + LTE radio, only in
this Part 2 report for Netgear 5G MHS Travel Router (FCC ID: PY319100441).

5.2 Measurement Setup
The Keysight Technologies E7515B UXM callbox is used in this test. The test setup is shown in
Figure 5-1a and the schematic of the setup is shown in Figure 5-1b. The UXM callbox has two
RF radio heads to up/down convert IF to mmW frequencies, which in turn are connected to two
horn antennas for V- and H-polarizations for downlink communication. In the uplink, a
directional coupler is used in the path of one of the horn antennas to measure and record radiated
power using a Rohde & Schwarz NR50S power sensor and NRP2 power meter. Note that since
the measurements performed in this validation are all relative, measurement of EUT’s radiated
power in one polarization is sufficient. The EUT is placed inside an anechoic chamber with V-
and H-pol horn antennas to establish the radio link as shown in Figure 5-1. The callbox’s LTE
port is directly connected to the EUT’s RF port via a directional coupler to measure the EUT’s
conducted Tx power using a Rohde & Schwarz NR8S power sensor and NRP2 power meter.
Additionally, EUT is connected to the PC via USB connection for sending beam switch
command. Care is taken to route the USB cable and RF cable (for LTE connection) away from
the EUT’s mmW antenna modules.
Setup in Figure 5-1 is used for the test scenario 1, 4 and 5 described in Section 2. The test
procedures described in Section 3 are followed. The path losses from the EUT to the power
meters are calibrated and used as offset in the power meter.

5-1, exposure between 15s ~110s corresponds to a normalized 4cm2PD exposure value for Beam
ID 158 of (75% * 2.11 W/m2)/(10 W/m2) = 15.8% ± 2.8dB device related uncertainty between
15s~110s). At 110s~120s time mark (shown in black dotted ellipse), beam is switched to Beam
ID 131 resulting in a normalized 4cm2PD exposure value of (75% * 1.12 W/m2)/(10 W/m2) =
8.4% ± 2.8dB device related uncertainty. Additionally, during the switch, the ratio between the
averaged radiated powers of the two beams (yellow curve) should correspond to the ratio of
EIRPs measured at each corresponding input.power.limit (within ±2.8dB device uncertainty) for
these beams listed in Table 5-1.

As can be seen, the power limiting enforcement is effective during beam switches and the total
normalized time-averaged RF exposure does not exceed 1.0. Therefore, Qualcomm Smart
Transmit time averaging algorithm is validated

6 PD Test Results for mmW Smart
Transmit Algorithm Validation

6.1 Measurement setup
The measurement setup is similar to normal PD measurements, the EUT is positioned on DASY
platform, and is connected with the callbox (conducted for LTE and wirelessly for mmW).
Keysight UXM callbox is set to request maximum mmW Tx power from EUT all the time.
Hence, “path loss” calibration between callbox antenna and EUT is not needed in this test. The
callbox’s LTE port is directly connected to the EUT’s RF port via a directional coupler to
measure the EUT’s conducted Tx power using a Rohde & Schwarz NR8S power sensor and
NRP2 power meter. Additionally, EUT is connected to the PC via USB connection for toggling
between FTM and online mode with Smart Transmit enabled following the test procedures
described Section 3.4.
Worst-surface of EUT (for the mmW beam being tested) is positioned facing up for PD
measurement with DASY mmW probe as shown in Figure 6-1. Figure 6-2 shows the schematic of
this measurement setup.

EUT surface is ~0.5 mm, and the distance between EUmmWV2 mmW probe sensor to probe tip
