Mounting Hardware
The board has three mounting holes at corners. Use #4 or M3 hardware for mounting the SocketModem to the
board. Refer to the Mechanical Drawings for more information.
The antenna system is defined as the UFL connection point from the device through the cable and antenna. Device
performance depends on implementation and antenna system design. Integrating the antenna system is a critical
part of the design process; therefore, it is essential to consider it early so the performance is not compromised.
Requirements for Cellular Antennas with regard to FCC/IC Compliance
The antenna must be the same type, with similar performance and in- and out-of-band radiation patterns as the
listed antenna. The antenna used must stay below the FCC/IC maximum gain.
For our bundles, MultiTech may change antennas over time. The listed antenna(s) is used as a reference or was
shipping when this document was last updated.
LTE Antenna
The cellular radio portion of the device is approved with the following antenna or for alternate antennas meeting
the given specifications. If using a different antenna, ensure

LTE Antenna Diversity
Antenna diversity uses two receive antennas to improve the downlink connection (cell tower to mobile). It has no
effect on the uplink (mobile to cell tower).
Antenna diversity is useful in environments where the signal arrives at the device after bouncing off or around
buildings or other objects. The bounced signal may be attenuated by going through semi-transparent (to the
signal) objects. Each signal alteration can change its magnitude, phase, orientation, or polarization. This complex
environment can exist in cities, inside buildings or in traffic. In this environment, signal paths from the cell tower
form an interference pattern of peaks and nulls. These peaks and nulls can be very close together.
Antenna diversity provides an advantage in complex environments because if one receive antenna has a poor
signal due to an interference null pattern, the other antenna is likely not in the null and has better reception. The
radio compares the reception from both receive antennas and uses the one with the strongest signal.
Important: You must deploy with two antennas, unless your carrier has authorized you to deploy with one
antenna.

ANTENNAS
Selecting Antennas
Select an antenna based on your product and application. Typically, both antennas are the same and either can be
the main receive antenna.
Placing External Antennas
Antennas are usually a quarter wavelength apart from each other. With multiband radios where the quarter
wavelengths in each band are diverse from each other, this rule may not be practical. Choose spacing based on the
band used most often or the band with connection difficulty. Some environments are harsher on particular bands.
MultiTech products have antenna connectors at the best spacing for the product size.
Placing antennas in close proximity to each other is not optimal, but you can do it if necessary. It depends on the
signal strength to and from each antenna.
If the antennas are too close together for your application, use a similar antenna on a short cable for the second
receive only antenna.
Placing GPS Antennas
GPS antennas need a clear view of the sky. Position the GPS antenna so the diversity antennas do not block its
view of the sky.
Antenna Approvals and Safety Considerations
Note the following:
Carriers conduct antenna diversity tests.
There are no EMC concerns about antenna diversity.
All antennas need to have a minimum flammability rating.
Safety requirements depend on your final product.
Unless otherwise noted, antennas certified by MultiTech are not approved for outdoor use. Do not extend
these antennas outside of any building.
Diversity and Power Draw
There are no significant power draw differences.

Interference with Pacemakers and Other Medical Devices
Potential interference
Radio frequency energy (RF) from cellular devices can interact with some electronic devices. This is
electromagnetic interference (EMI). The FDA helped develop a detailed test method to measure EMI of implanted
cardiac pacemakers and defibrillators from cellular devices. This test method is part of the Association for the
Advancement of Medical Instrumentation (AAMI) standard. This standard allows manufacturers to ensure that
cardiac pacemakers and defibrillators are safe from cellular device EMI.
The FDA continues to monitor cellular devices for interactions with other medical devices. If harmful interference
occurs, the FDA will assess the interference and work to resolve the problem.
Precautions for pacemaker wearers
If EMI occurs, it could affect a pacemaker in one of three ways:
Stop the pacemaker from delivering the stimulating pulses that regulate the heart's rhythm.
Cause the pacemaker to deliver the pulses irregularly.
Cause the pacemaker to ignore the heart's own rhythm and deliver pulses at a fixed rate.
Based on current research, cellular devices do not pose a significant health problem for most pacemaker wearers.
However, people with pacemakers may want to take simple precautions to be sure that their device doesn't cause
a problem.
Keep the device on the opposite side of the body from the pacemaker to add extra distance between the
pacemaker and the device.
Avoid placing a turned-on device next to the pacemaker (for example, don’t carry the device in a shirt or
jacket pocket directly over the pacemaker).
Vehicle Safety
When using your device in a vehicle:
Do not use this device while driving.
Respect national regulations on the use of cellular devices in vehicles.
If incorrectly installed in a vehicle, operating the wireless device could interfere with the vehicle’s
electronics. To avoid such problems, use qualified personnel to install the device. The installer should verify
the vehicle electronics are protected from interference.
Using an alert device to operate a vehicle’s lights or horn is not permitted on public roads.
UL evaluated this device for use in ordinary locations only. UL did NOT evaluate this device for installation in
a vehicle or other outdoor locations. UL Certification does not apply or extend to use in vehicles or outdoor
applications.
