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.

Limitation of Liability

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.

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.

1: Introduction

The Sierra Wireless MC7475 PCI Express Mini Card is a compact, lightweight, wireless modem that provides LTE and GPS connectivity for M2M applications, notebook, ultrabook and tablet computers over several radio frequency bands.

Supported RF Bands

The modem, based on the Altair FourGee6300 baseband processor, supports data operation on LTE networks over the bands described in Table 1-1.

Table 1-1: Supported RF Bands

Technology Bands Notes

LTE 2, 4, 12, 125 Data rates:

GPS 1575.42 MHz

• Downlink (Cat 4):

FDD: 150 Mbps

• Uplink (Cat 4):

FDD: 50 Mbps

Physical Features

• Small form factor—conforms to type F2 as specified in PCI Express Mini Card Electromechanical Specification Revision 1.2.

• Ambient operating temperature range:

· Class A (3GPP compliant): -20°C to +70°C

· Class B (operational, non-3GPP compliant): -30°C to +85°C (reduced

operating parameters required)

Important: The internal module temperature must be kept below 90°C. For best perfor-

mance, the internal module temperature should be kept below 80°C. Proper mounting, heat sinks, and active cooling may be required, depending on the integrated application.

Power—Supplied to the module by the host. WAKE_N— Signal used to wake the host when specific events occur.

•

WAN_LED_N—Active-low LED drive signal provides an indication of RADIO ON

•

state, either WAN or GPS.

•

SYSTEM_RESET_N—Active-low reset input.

•

Antenna—Three U.FL RF connectors (main (Rx /Tx), GPS, and auxiliary (Rx

diversity). For details, see RF Specifications on page 24.

•

Antenna control—Three signals that can be used to control external antenna

switches.

•

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 interface to the host for data, control, and status information.

The MC7475 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.

Host Interface Pin Assignments

The MC7475 host I/O connector provides pins for power, serial communications, and control. Pin assignments are listed in Table 3-1.

Refer to the following tables for pin details based on interface types:

• Table 3-2, Power and Ground Specifications, on page 18

• Table 3-3, USB Interfaces, on page 18

• Table 3-4, SIM Interface Signals, on page 19

• Table 3-5, Module Control Signals, on page 22

Note: On any given interface (USB, SIM, etc.), leave unused inputs and outputs as noconnects.

Note: The host should not drive any signals to the module until the power-on sequence is complete.

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. 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.

f. Max voltage level when current < 100 mA.

Power Supply

The host provides power to the MC7475 through multiple power and ground pins as summarized in Table 3-2.

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 signals is required.

The device supports a USB 2.0 interface for communication between the host and module.

The interface complies with the [7] Universal Serial Bus Specification, Rev 2.0, and the host device must be designed to the same standards (subject to details shown in Table 3-3 below). (Note: When designing the host device, careful PCB layout practices must be followed.)
