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.
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 EM7511 Embedded Module is an M.2 module that provides LTE,
UMTS, and GNSS connectivity for notebook, ultrabook, tablet computers, and M2M
applications over several radio frequency bands.
Accessories
A hardware development kit is available for AirPrime M.2 modules. The kit contains
hardware components for evaluating and developing with the module, including:
• Development board
• Cables
• Antennas
• Other accessories
For over-the-air LTE testing, ensure that suitable antennas are used.
Required Connectors
Table 1-1 describes the connectors used to integrate the EM7511 Embedded Module
into your host device.

Table 1-1: Required Host–Module Connectors
Connector type Description
RF cables • Mate with M.2-spec connectors
• Three connector jacks (I-PEX 20448-001R-081 or equivalent)
EDGE (67 pin) • Slot B compatible—Per the M.2 standard ([8] PCI Express NGFF
SIM • Industry-standard connector.
(M.2) Electromechanical Specification Revision 1.0), a generic
75 pin position EDGE connector on the motherboard uses a
mechanical key to mate with the 67 pin notched module connector.
• Manufacturers include LOTES (part #APCI0018-P001A01),
Kyocera, JAE, Tyco, and Longwell.

2: Power
Power Supply
The host provides power to the EM7511 through multiple power and ground pins. 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.
For detailed pinout and voltage/ current requirements of this module, see the AirPrime
EM7511 Product Technical Specification.
Module Power States
The module has five power states, as described in Table 2-1.
Table 2-1: Module Power States
2
State Details
Normal
(Default
state)
Low power
(‘Airplane
mode’)
Sleep • Normal state of module between calls or data connections
• Module is active
• Default state. Occurs when VCC is first applied, Full_Card_Power_Off# is deasserted
(pulled high), and W_DISABLE# is deasserted
• Module is capable of placing/receiving calls, or establishing data connections on the
wireless network
• Current consumption is affected by several factors, including:
• Radio band being used
• Transmit power
• Receive gain settings
• Data rate
• Module is active
• Module enters this state:
• Under host interface control:
· Host issues AT+CFUN=0 (AT Command Set for User Equipment (UE) (Release 6)
(Doc# 3GPP TS 27.007))), or
· Host asserts W_DISABLE#, after AT!PCOFFEN=0 has been issued.
• Automatically, when critical temperature or voltage trigger limits have been reached))
• Module cycles between wake (polling the network) and sleep, at network provider-deter-
mined interval.
Host is powered
USB interface active
RF enabled
