Product Technical Specification
Important
Notice
Safety and
Hazards
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.
Do not operate the Sierra Wireless modem in areas where blasting is in progress, where
explosive atmospheres may be present, near medical equipment, near life support
equipment, or any equipment which may be susceptible to any form of radio interference.
In such areas, the Sierra Wireless modem MUST BE POWERED OFF. 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.

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

The system block diagram in Figure 2-1 on page 18 represents the MC7411 module
integrated into a host system. The module includes the following interfaces to the host:
• Power—Supplied to the module by the host.
• W_DISABLE_N—Input supplied to the module by the host to cause the module to
either turn off/on or enter/exit low power mode (software configurable).
• WAKE_N— Signal used to wake the host when specific events occur.
• WAN_LED_N—Active-low LED drive signal provides an indication of WAN radio ON
state.
• SYSTEM_RESET_N—Active-low reset input.
• Antenna—Three U.FL RF connectors (main (Rx/Tx), GNSS, and auxiliary (diversity/
MIMO/GNSS). For details, see RF Specifications on page 35.
• Antenna control—Three signals that can be used to control external antenna
switches.
• Dynamic power control—Signal used to adjust Tx power to meet FCC/CE SAR
requirements. For details, see Tx Power Control on page 50.
• Dual SIM—Supported through the interface connector. The SIM cavities / connectors
must be placed on the host device for this feature.
• USB—USB 2.0 and USB 3.0 interfaces to the host for data, control, and status information.

c. Signal directions are from module’s point of view (e.g. ‘Output’ from module to host, ‘Input’ to module from host.)
d. To avoid adverse effects on module operation, do not draw more than 10 mA current on pin 11.
e. Sierra Wireless recommends that the host implement an open collector driver where a Low signal will turn the module off or enter
low power mode, and a high signal will turn the module on or leave low power mode.
f. The module must not be plugged into a port that supports PCI Express—the pin is used by a PCIE signal, which can cause the
module to be in reset state or occasionally reset.

Electrical Specifications
Power Supply
The host provides power to the MC7411 through multiple power and ground pins as
summarized in Table 2-2.
The host must provide safe and continuous power at all times; the module does not have
an independent power supply, or protection circuits to guard against electrical issues.

USB Interface
Important: Host support for USB 2.0 or USB 3.0 signals is required.
The device supports USB 2.0 (high speed) and USB 3.0 interfaces for communication
between the host and module.
Important: USB 2.0 full speed and low speed are not supported.
The interfaces comply with the [10] Universal Serial Bus Specification, Rev 2.0 and [11]
Universal Serial Bus Specification, Rev 3.0 (subject to limitations described below), and
the host device must be designed to the same standards.

Host-side Recommendation
Note: When designing the host device, careful PCB layout practices must be followed.
Sierra Wireless recommends the host platform include series capacitors on the USB3.0
Rx signals (no capacitors required for the Tx signals), as shown below.

USB Throughput Performance
This device has been designed to achieve optimal performance and maximum throughput
using USB superspeed mode (USB 3.0). Although the device may operate with a high
speed host, throughput performance will be on an “as is” basis and needs to be
characterized by the OEM. Note that throughput will be reduced and may vary
significantly based on packet size, host interface, and firmware revision.
User-developed Drivers
Details for user-developed USB drivers are described in [4] AirCard/AirPrime USB Driver
Developer’s Guide (Doc# 2130634).
SIM Interface
Note: Host support for SIM interface signals is required.
The module supports up to two SIMs (Subscriber Identity Module) (1.8 V or 3 V). Each
SIM holds information for a unique account, allowing users to optimize their use of each
account on multiple devices.
The SIM pins (Table 2-4) provide the connections necessary to interface to SIM sockets
located on the host device as shown in Figure 2-5 on page 28. Voltage levels over this
interface comply with 3GPP standards.
Rev 4 Feb.21

Electrical Specifications
Note: Sprint requires the use of ISIM. USIM and CSIM are not supported per Sprint implementation.
The types of SIM connectors used depends on how the host device exposes the SIM
sockets.

SIM Implementation
Note: For interface design requirements, refer to ETSI TS 102 230 V5.5.0, section 5.2.
When designing the remote SIM interface, you must make sure that SIM signal integrity is
not compromised.
Some design recommendations include:
• Total impedance of the VCC and GND connections to the SIM, measured at the
module connector, should be less than 1 to minimize voltage drop (includes any
trace impedance and lumped element components—inductors, filters, etc.).
• Position the SIM connector 10 cm from the module. If a longer distance is required
because of the host device design, use a shielded wire assembly—connect one end
as close as possible to the SIM connector and the other end as close as possible to
the module connector. The shielded assembly may help shield the SIM interface from
system noise.
• Reduce crosstalk on the USIM_DATA and USIM2_DATA lines to reduce the risk of
failures during GCF approval testing.
• Avoid routing the clock and data lines for each SIM (USIM_CLK/USIM_DATA,
USIM2_CLK/USIM2_DATA) in parallel over distances 2 cm—cross-coupling of a
clock and data line pair can cause failures.
• 3GPP has stringent requirements for I/O rise time (
