Important

Notice 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.

Safety and

Hazards 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.

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.

1: Introduction

The Sierra Wireless EM7355 Embedded Module is an M.2 modem

that provides LTE, DC-HSPA+, HSPA+, HSDPA, HSUPA, WCDMA,

GSM, GPRS, EDGE, CDMA, and GNSS connectivity for notebook,

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

Table 1-1 describes the connectors used to integrate the EM7355

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

EDGE (67 pin) •Slot B compatible—Per the M.2 standard (PCI Express NGFF

(M.2) Electromechanical Specification Revision 0.7), 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.

SIM •Industry-standard connector.

2: Power

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.

For detailed pinout and voltage/current requirements of this module,

see the AirPrime EM7355 Product Technical Specification &

Customer Design Guidelines.

Module power states

The module has five power states, as described in Ta b l e 2-1.

RF enabled

Normal

(Default

state)

•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

   

Low power

(‘Airplane

mode’)

•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))

Sleep •Normal state of module between calls or data connections

•Module cycles between wake (polling the network) and sleep, at network provider-

determined interval.

   

Off •Host keeps module powered off by asserting Full_Card_Power_Off# (signal pulled

low or left floating)

•Module draws minimal current

•See Full_Card_Power_Off# and RESET# on page 41 for more information.

  

Disconnected •Host power source is disconnected from the module and all voltages associated with

the module are at 0 V.    
