AirPrime EM7411 Product Technical Specification 41113694 Rev 5 Proprietary and Confidential Contents subject to change 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 product are used in a normal manner with a well-constructed network, the Sierra Wireless product 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 product, or for failure of the Sierra Wireless product to transmit or receive such data. Do not operate the Sierra Wireless product 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 product MUST BE POWERED OFF. The Sierra Wireless product can transmit signals that could interfere with this equipment. Do not operate the Sierra Wireless product in any aircraft, whether the aircraft is on the ground or in flight. In aircraft, the Sierra Wireless product MUST BE POWERED OFF. When operating, the Sierra Wireless product 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 products may be used at this time. The driver or operator of any vehicle should not operate the Sierra Wireless product 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. Limitation of Liability 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.

Host interface —Compliance with interface voltage levels 16 41113694 2 2: Electrical Specifications The system block diagram in Figure 2-1 represents the EM7411 module integrated into a host system. The module includes the following interfaces to the host: • Full_Card_Power_Off#—Input supplied to the module by the host—active-low to turn the unit off, or active-high to turn the unit on. • W_DISABLE1#—Active low input from the host to the EM7411 disables the main RF radio. • W_DISABLE2#—Active low input from the host to the EM7411 disables the GNSS radio receiver. • WAKE_ON_WAN#—Active low output used to wake the host when specific events occur. • WWAN_LED#—Active-low LED drive signal provides an indication of WAN radio ON state. • RESET#—Active low input from the host used to reset the module. • Antenna—Three RF connectors (main (Rx/Tx), GNSS, and auxiliary (diversity/MIMO/ GNSS)). For details, see RF Specifications on page 36. • Antenna control—Four signals that can be used to control external antenna switches. • Dynamic power control—Signal used to adjust Tx power to meet FCC SAR requirements. For details, see Tx Power Control on page 52.). • Dual SIM—Supported through the interface connector. The SIM cavities / connectors must be placed on the host device for this feature. • SIM detect—Internal pullup on the module detects whether a SIM is present or not: · If a SIM is not inserted, the pin must be shorted to ground. · If a SIM is present, the pin will be an open circuit. • USB—USB 2.0 and USB 3.0 interfaces to the host for data, control, and status information. The EM7411 has two main interface areas—the host I/O connector and the RF ports. Details of these interfaces are described in the sections that follow.

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. Power Supply The host provides power to the EM7411 through multiple power and ground pins as summarized in Table 2-2. The host must provide safe and continuous power (via battery or a regulated power supply) at all times; the module does not have an independent power supply, or protection circuits to guard against electrical issues.

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 on page 27) 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.

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 UIM1_DATA and UIM2_DATA lines to reduce the risk of failures during GCF approval testing. • Avoid routing the clock and data lines for each SIM (UIM1_CLK/UIM1_DATA, UIM2_CLK/UIM2_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 (
