Important Notice
Due to the nature of wireless communications, transmission and reception of data can never be
guaranteed. Data may be delayed, corrupted (i.e., have errors) or be totally lost. Although significant
delays or losses of data are rare when wireless devices such as the Sierra Wireless modem are used
in a normal manner with a well-constructed network, the Sierra Wireless modem should not be used
in situations where failure to transmit or receive data could result in damage of any kind to the user or
any other party, including but not limited to personal injury, death, or loss of property. Sierra Wireless
accepts no responsibility for damages of any kind resulting from delays or errors in data transmitted or
received using the Sierra Wireless modem, or for failure of the Sierra Wireless modem to transmit or
receive such data.
Safety and Hazards
Do not operate the Sierra Wireless modem in areas where cellular modems are not advised without
proper device certifications. These areas include environments where cellular radio can interfere such
as explosive atmospheres, medical equipment, or any other equipment which may be susceptible to
any form of radio interference. The Sierra Wireless modem can transmit signals that could interfere
with this equipment. Do not operate the Sierra Wireless modem in any aircraft, whether the aircraft is
on the ground or in flight. In aircraft, the Sierra Wireless modem MUST BE POWERED OFF. When
operating, the Sierra Wireless modem can transmit signals that could interfere with various onboard
systems.
Note: Some airlines may permit the use of cellular phones while the aircraft is on the ground and the door
is open. Sierra Wireless modems may be used at this time.
The driver or operator of any vehicle should not operate the Sierra Wireless modem while in control of
a vehicle. Doing so will detract from the driver or operator’s control and operation of that vehicle. In
some states and provinces, operating such communications devices while in control of a vehicle is an
offence.
Limitations of Liability
This manual is provided “as is”. Sierra Wireless makes no warranties of any kind, either expressed or
implied, including any implied warranties of merchantability, fitness for a particular purpose, or
noninfringement. The recipient of the manual shall endorse all risks arising from its use.
The information in this manual is subject to change without notice and does not represent a
commitment on the part of Sierra Wireless. SIERRA WIRELESS AND ITS AFFILIATES
SPECIFICALLY DISCLAIM LIABILITY FOR ANY AND ALL DIRECT, INDIRECT, SPECIAL,
GENERAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES INCLUDING,
BUT NOT LIMITED TO, LOSS OF PROFITS OR REVENUE OR ANTICIPATED PROFITS OR
REVENUE ARISING OUT OF THE USE OR INABILITY TO USE ANY SIERRA WIRELESS
PRODUCT, EVEN IF SIERRA WIRELESS AND/OR ITS AFFILIATES HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES OR THEY ARE FORESEEABLE OR FOR CLAIMS BY ANY
THIRD PARTY.
Notwithstanding the foregoing, in no event shall Sierra Wireless and/or its affiliates aggregate liability
arising under or in connection with the Sierra Wireless product, regardless of the number of events,
occurrences, or claims giving rise to liability, be in excess of the price paid by the purchaser for the
Sierra Wireless product.

Measured at the RF connector.
Includes mismatch losses, losses in the
matching circuit, and antenna losses,
excluding cable loss.
Sierra Wireless recommends using
antenna efficiency as the primary
parameter for evaluating the antenna
system.
Peak gain is not a good indication of
antenna performance when integrated with
a host device (the antenna does not
provide omni-directional gain patterns).
Peak gain can be affected by antenna size,
location, design type, etc. —the antenna
gain patterns remain fixed unless one or
more of these parameters change.
Maximum antenna
gain
Must not exceed antenna gains due to
RF exposure and ERP/ EIRP limits,
as listed in the module’s FCC grant.
Isolation between
Ant1 and Ant2 (S21)
> 10 dB
If antennas can be moved, test all
positions for both antennas.
Unless otherwise specified, this
isolation requirement need to be
maintained for optimum operation.
Make sure all other wireless devices
(Bluetooth or WLAN antennas, etc.) are
turned OFF to avoid interference.

> 1 W on high bands
Measure power endurance over 4
hours (estimated talk time) using a 2 W
CW signal —set the CW test signal
frequency to the middle of the PCS TX
band (1880 MHz for PCS).
Visually inspect device to ensure there
is no damage to the antenna structure
and matching components.
VSWR / TIS / TRP measurements
taken before and after this test must
show similar results.
* These worst-case VSWR figures for the transmitter bands may not guarantee RSE levels to be within regulatory limits.
The device alone meets all regulatory emissions limits when tested into a cabled (conducted) 50Ω system. With antenna
designs with up to 2.5:1 VSWR or worse, the radiated emissions could exceed limits. The antenna system may need to be
tuned in order to meet the RSE limits as the complex match between the module and antenna can cause unwanted levels
of emissions. Tuning may include antenna pattern changes, phase/delay adjustment, passive component matching.
Examples of the application test limits would be included in FCC Part 22, Part 24 and Part 27, test case 4.2.16 for GSM
(ETSI EN 301 511), and test case 4.2.2 for WCDMA (ETSI EN 301 908-1), where applicable.

1.4. GNSS
The AirPrime AR759x Series include optional Global Navigation Satellite System (GNSS) capabilities
via the Qualcomm gpsOne Gen8C Engine, capable of operation in assisted and stand-alone modes
using GPS, GLONASS, Beidou, Galileo, and QZSS SVs.
Note: Galileo support pending system / satellite deployment.

Note: All GNSS characterization data are measured in conducted RF path with GNSS simulator.
Note 1: Open sky, all SV RF signal level = -130dBm, Number of SVs > 6
Note 2: TTFF values show results in worst conditions (as an external host user): timing measurement start
when GPS control request is sent on AT command interface and stop when NMEA frames (1Hz
update) display 2D fix information.

Introduction
Note 3: Scenarios used for accuracy measurements simulate car travel including direction, altitude and
speed variations.
Note 4: Best performances are obtained by using external Pre-SAW and LNA for conducted test setup, it is
used to simulate the active antenna as customer’s application.
Note 5: 1Hz Navigation used for all tracking/navigation tests.
Note 6: GNSS constellations used: GPS + GLONASS + Galileo + Beidou
Note 7: Accuracy data are provided Circular Error Probable, CEP-50 / CEP-95. Means that 50%/95% of the
positions returned calculated have an error lower or equal to the accuracy value.

Introduction
Caution: Digital IOs shall not be pulled-up to an external voltage as this may cause VCC_1V8 to not go low
when the AirPrime AR759x Series are powered down. Also, this would partially bias the AirPrime
AR759x Series which could potentially damage the device or result in GPIOs being set to
undetermined levels.
