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.

3.1.1. Ground Connection Guidelines
When connecting the module to system ground:
Prevent noise leakage by establishing a very good ground connection to the module through
the host connector.
Minimize ground noise leakage into the RF.
Depending on the host board design, noise could potentially be coupled to the module from
the host board. This is mainly an issue for host designs that have signals traveling along the
length of the module, or circuitry operating at both ends of the module interconnects.
3.1.2. Shielding Guidelines
The module is fully shielded to protect against EMI and to ensure compliance with FCC Part 15 -
“Radio Frequency Devices” (or equivalent regulations in other jurisdictions).
Note: This shielding must NOT be removed.
3.2. Antenna Guidelines
3.2.1. Choosing the Correct Antenna and Cabling
Consider the following points for appropriate antenna selection:
The antenna (and associated circuitry) should have a nominal impedance of 50Ω with a return
loss of better than 10 dB across each frequency band of operation.
The system gain value affects both radiated power and regulatory (FCC, IC, CE, etc.) test
results.
4112719 Rev 2.1 January 07, 2013 13
Hardware Integration Guide
RF Integration
3.2.2. Determining the Antenna’s Location
Consider the following points when deciding where to place the antenna:
Antenna location may affect RF performance. Although the module is shielded to prevent
interference in most applications, the placement of the antenna is still very important—if the
host device is insufficiently shielded, high levels of broadband or spurious noise can degrade
the module’s performance.
Connecting cables between the module and the antenna must have 50Ω impedance. If the
impedance of the module is mismatched, RF performance is reduced significantly.
Antenna cables should be routed, if possible, away from noise sources (switching power
supplies, LCD assemblies, etc.). If the cables are near the noise sources, the noise may be
coupled into the RF cable and into the antenna.
3.3. RF Desense Sources
Common sources of interference that may affect the module’s RF performance (RF desense) include
Power supply noise
Can lead to noise in the RF signal
Module power supply ripple limit <= 100 mVp-p 1 Hz–100 kHz
Interference from other embedded wireless devices
Any harmonics, sub-harmonics, or cross-products of signals that fall in the module’s Rx
range may cause spurious response, resulting in decreased Rx performance.
Tx power and corresponding broadband noise may overload or increase the noise floor of
the module’s receiver, resulting in RF desense.
Severity of interference depends on proximity of other antennas to the module’s
antennas.
Host electronic device-generated RF
Proximity of host electronics to the module’s antenna can contribute to decreased Rx
performance.
Some devices include microprocessor and memory, display panel and display drivers,
and switching mode power supplies.
Note: In practice, there are usually numerous interfering frequencies and harmonics. The net effect can
be a series of desensitized receive channels.
4112719 Rev 2.1 January 07, 2013 14
4. RF Circuit Routing Constraints
To route the RF antenna signals, the following recommendations must be observed for PCB layout:
The RF signals must be routed using traces with a 50 characteristic impedance.
Basically, the characteristic impedance depends on the dielectric constant (εr) of the material used,
trace width (W), trace thickness (T), and height (H) between the trace and the reference ground plane.
In order to respect this constraint, Sierra Wireless recommends that a MicroStrip structure be used
and trace width be computed with a simulation tool (such as AppCAD, shown in the figure below and
available free of charge at http://www.avagotech.com).
Figure 1. AppCAD Screenshot for MicroStrip Design Power Mode Diagram
The trace width should be wide enough to maintain reasonable insertion loss and manufacturing
reliability. Cutting out inner layers of ground under the trace will increase the effective substrate
height; therefore, increasing the width of the RF trace.
Caution: It is critical that no other signals (digital, analog, or supply) cross under the RF path. The figures
below show generic examples of good routing techniques.
Figure 2. RF Routing Example with Lead Type RF Connectors
4112719 Rev 2.1 January 07, 2013 15
Hardware Integration Guide
RF Circuit Routing Constraints
Figure 3. RF Routing Example with SMT Type RF Connectors
Fill the area around the RF traces with ground and ground vias to connect inner ground layers
for isolation.
Cut out ground fill under RF signal pads to reduce stray capacitance losses.
Avoid routing RF traces with sharp corners. A smooth radius is recommended.
The ground reference plane should be a solid continuous plane under the trace.
The coplanar clearance (G, below) from the trace to the ground should be at least the trace
width (W) and at least twice the height (H). This reduces the parasitic capacitance, which
potentially alters the trace impedance and increases the losses. Note the figure below shows
several internal ground layers cutout, which may not be necessary for every application.

6. Regulatory Information
6.1. Important Notice
Because of 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
and its affiliates accept 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.
6.2. Safety and Hazards
Do not operate your AirPrime SL8084T modem:
In areas where blasting is in progress
Where explosive atmospheres may be present including refueling points, fuel depots, and
chemical plants
Near medical equipment, life support equipment, or any equipment which may be susceptible

OFF. Otherwise, the SL8084T modem can transmit signals that could interfere with this
equipment.
In an aircraft, the SL8084T modem MUST BE POWERED OFF. Otherwise, the SL8084T modem can
transmit signals that could interfere with various onboard systems and may be dangerous to the
operation of the aircraft or disrupt the cellular network. Use of a cellular phone in an aircraft is illegal in
some jurisdictions. Failure to observe this instruction may lead to suspension or denial of cellular
telephone services to the offender, or legal action or both.
Some airlines may permit the use of cellular phones while the aircraft is on the ground and the door is
open. The SL8084T modem may be used normally at this time.
6.3. Important Compliance Information for North
American Users
The SL8084T modem has been granted modular approval for mobile applications. Integrators may
use the SL8084T modem in their final products without additional FCC/IC (Industry Canada)
certification if they meet the following conditions. Otherwise, additional FCC/IC approvals must be
obtained.
1. At least 20 cm separation distance between the antenna and the user’s body must be
maintained at all times.
2. To comply with FCC/IC regulations limiting both maximum RF output power and human
exposure to RF radiation, the maximum antenna gain including cable loss in a mobile-only
exposure condition must not exceed 6 dBi in the cellular band and 3.5 dBi in the PCS band.
3. The SL8084T modem and its antenna must not be co-located or operating in conjunction with
any other transmitter or antenna within a host device.
