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.

Rev Apr.18 9

Product Technical Specification

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.

Rev Apr.18 10

RF Specifications

Ground Connection
When connecting the module to system ground:
• Prevent noise leakage by establishing a very good ground connection to the
module through the host connector.
• Connect to system ground using the module’s mounting hole.
• Minimize ground noise leakage into the RF.
Depending on the host board design, noise could potentially be coupled to
the module from the host board. This is mainly an issue for host designs that
have signals traveling along the length of the module, or circuitry operating at
both ends of the module interconnects.

Interference and Sensitivity
Several interference sources can affect the module’s RF performance
(RF desense). Common sources include power supply noise and device-
generated RF.
RF desense can be addressed through a combination of mitigation techniques
(Methods to Mitigate Decreased Rx Performance on page 12) and radiated
sensitivity measurement (Radiated Sensitivity Measurement on page 12).

Note: The EM7511 is based on ZIF (Zero Intermediate Frequency) technologies. When
performing EMC (Electromagnetic Compatibility) tests, there are no IF (Intermediate
Frequency) components from the module to consider.

Interference From Other Wireless Devices
Wireless devices operating inside the host device can cause interference that
affects the module.
To determine the most suitable locations for antennas on your host device,
evaluate each wireless device’s radio system, considering the following:
• Any harmonics, sub-harmonics, or cross-products of signals generated by
wireless devices that fall in the module’s Rx range may cause spurious
response, resulting in decreased Rx performance.
• The Tx power and corresponding broadband noise of other wireless devices
may overload or increase the noise floor of the module’s receiver, resulting in
Rx desense.
The severity of this interference depends on the closeness of the other antennas
to the module’s antenna. To determine suitable locations for each wireless
device’s antenna, thoroughly evaluate your host device’s design.

Host-generated RF Interference
All electronic computing devices generate RF interference that can negatively
affect the receive sensitivity of the module.

Rev Apr.18 11

RF Specifications

To determine the extent of any receiver performance desensitization due to self-
generated noise in the host device, over-the-air (OTA) or radiated testing is
required. This testing can be performed by Sierra Wireless or you can use your
own OTA test chamber for in-house testing.

Important Notice
Because of 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 module are used in a normal manner with a well-
constructed network, the Sierra Wireless module 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 and its affiliates accept no responsibility for damages of any
kind resulting from delays or errors in data transmitted or received using the Sierra
Wireless module, or for failure of the Sierra Wireless module to transmit or receive
such data.

Safety and Hazards
Do not operate your EM7511 module:
• In areas where blasting is in progress
• Where explosive atmospheres may be present including refuelling points, fuel
depots, and chemical plants
• Near medical equipment, life support equipment, or any equipment which may be
susceptible to any form of radio interference. In such areas, the EM7511 module
MUST BE POWERED OFF. Otherwise, the EM7511 module can transmit signals
that could interfere with this equipment.

Rev Apr.18 14

Regulatory Compliance and Industry Certifications

*Important: The FCC and IC have a strict EIRP limit in Band 30 for mobile and portable stations in order to protect
adjacent satellite radio, aeronautical mobile telemetry, and deep space network operations. Mobile and portable stations
must not have antenna gain exceeding 1 dBi in Band 30. Additionally, both the FCC and IC prohibit the use of external
vehicle-mounted antennas for mobile and portable stations in this band.

Fixed stations may use antennas with higher gain in Band 30 due to relaxed EIRP limits. EM7511 modules used as fixed
subscriber stations in Canada or fixed customer premises equipment (CPE) stations in the United States may have an
antenna gain up to 10 dBi in Band 30, however, the use of outdoor antennas or outdoor station installations are
prohibited except if professionally installed in locations that are at least 20 meters from roadways or in locations where it
can be shown that the ground power level of -44 dBm per 5 MHz in the bands 2305–2315 MHz and 2350–2360 MHz or
-55 dBm per 5 MHz in the bands 2315–2320 MHz and 2345–2350 MHz will not be exceeded at the nearest roadway. For
the purposes of this notice, a roadway includes a highway, street, avenue, parkway, driveway, square, place, bridge,
viaduct or trestle, any part of which is intended for use by the general public for the passage of vehicles.

Mobile carriers often have limits on total radiated power (TRP), which requires an efficient antenna. The end product with
an embedded module must output sufficient power to meet the TRP requirement but not too much to exceed FCC/IC's
EIRP limit. If you need assistance in meeting this requirement, please contact Sierra Wireless.
