Preface

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

n the ground or in flight. In aircraft, the Sierra Wireless modem MUST BE

o
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.

Limitation of
Liability

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 agg
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.

ultrabook, and tablet computers over several radio frequency bands.
The device also supports 2G / 3G roaming.

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

Tab le 1 - 1 describes the connectors used to integrate the EM7355

Embedded Module into your host device.

Table 2-1: Module power states

State Details

Power supply

The host provides power to the EM7355 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.

• Module is active

• Default state. Occurs when VCC is first applied, Full_Card_Power_Off# is

deasserted (pulled high), and W_DISABLE#1 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 ([1] AT Command Set for User Equipment (UE)

(Release 6) (Doc# 3GPP TS 27.007))), or

· Host asserts W_DISABLE#1, after AT!PCOFFEN=0 has been issued.

• Automatically, when critical temperature or voltage trigger limits have been

reached))
