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

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.

RF Connections

When attaching antennas to the module:

•Use RF plug connectors that are compatible with the following RF receptacle

connectors: Foxconn (KK12011-02-7H), Longwell (911-002-0006R),

Speedtech (C87P101-00001-H), Murata (MM4829-2702RA4 (HSC)), IPEX

(20449-001E (MHF4)).

•Match coaxial connections between the module and the antenna to 50 .

•Minimize RF cable losses to the antenna; the recommended maximum cable

loss for antenna cabling is 0.5 dB.

•To ensure best thermal performance, use the mounting hole (if possible) to

attach (ground) the device to a metal chassis.

Note: If the antenna connection is shorted or open, the modem will not sustain permanent

damage.

Shielding

The module is fully shielded to protect against EMI and must not be removed.

Antenna and Cabling

When selecting the antenna and cable, it is critical to RF performance to match

antenna gain and cable loss.

Choosing the Correct Antenna and Cabling

When matching antennas and cabling:

•The antenna (and associated circuitry) should have a nominal impedance of

50 with a return loss of better than 10 dB across each frequency band of

operation.

•The system gain value affects both radiated power and regulatory (FCC, IC,

CE, etc.) test results.

Designing Custom Antennas

Consider the following points when designing custom antennas:

•A skilled RF engineer should do the development to ensure that the RF

performance is maintained.

•If both UMTS and CDMA modules will be installed in the same platform, you

may want to develop separate antennas for maximum performance.

Determining the Antenna’s Location

When deciding where to put the antennas:

•Antenna location may affect RF performance. Although the module is

shielded to prevent interference in most applications, the placement of the

antenna is still very important—if the host device is insufficiently shielded,

high levels of broadband or spurious noise can degrade the module’s perfor-

mance.

•Connecting cables between the module and the antenna must have 50 

impedance. If the impedance of the module is mismatched, RF performance

is reduced significantly.

•Antenna cables should be routed, if possible, away from noise sources

(switching power supplies, LCD assemblies, etc.). If the cables are near the

noise sources, the noise may be coupled into the RF cable and into the

antenna.

Disabling the Diversity Antenna

Use the AT command !RXDEN=0 to disable receive diversity or !RXDEN=1 to

enable receive diversity.

Note: A diversity antenna is used to improve connection quality and reliability through

redundancy. Because two antennas may experience difference interference effects (signal

distortion, delay, etc.), when one antenna receives a degraded signal, the other may not be

similarly affected.
