Modem Integration Guide
1. Safety Precautions
1.1. Important Safety Information
The following information applies to the devices described in this manual. Always observe all standard and
accepted safety precautions and guidelines when handling any electrical device.
•Save this manual: it contains important safety information and operating instructions.
•Do not expose the Enfora Enabler IIIG product to open flames.
•Ensure that liquids do not spill onto the devices.
•Do not attempt to disassemble the product: Doing so will void the warranty. With the
exception of the Subscriber Identification Module (SIM), this product does not contain
consumer-serviceable components.
2. Regulatory Compliance FCC
2.1. Integration Considerations and Installation Requirements
The Enabler IIIG modem is designed for use in a variety of host units, "enabling" the host platform
to perform wireless data communications. However, there are certain criteria relative to
integrating the modem into a host platform such as a PC, laptop, handheld or PocketPC®, monitor
and control unit, etc. that must be considered to ensure continued compliance with FCC
compliance requirements.
•Operation is subject to the following two conditions: (1) this device may not cause
interference, and (2) this device must accept any interference, including interference that may
cause undesired operation of the device.
•In order to use the Enabler IIIG modem without additional FCC certification approvals, the
installation must meet the following conditions:
Maximum RF output power and antenna gain to meet Maximum Permissible Exposure
Requirements: GSM850 mode: Power at antenna port is +32 dBm. The maximum gain
is 4.5 dBi (2.35 dBd). GSM1900 mode: Power at antenna port is 31.3 dBm. The
maximum gain is 2 dBi in order to meet the requirements of maximum 2 watts EIRP for
mobile transmitters. If RF power and/or antenna gain is desired, a separate FCC
certification is required.
•If used in a "portable" application such as a handheld or body worn device with the
antenna less than 20 cm (7.9 in.) from the human body when the device is operating,
then the integrator is responsible for passing additional "as installed" testing and the
device will require it’s own FCC ID:
•SAR (Specific Absorption Rate) testing, with results submitted to the FCC for
approval prior to selling the integrated unit. If unable to meet SAR requirements,
then the host unit must be restricted to "mobile" use (see below).

Enfora Enabler IIIG M2M
Modem Integration Guide
•Unintentional emissions, FCC Part 15; results do not have to be submitted to the
FCC unless requested, although the test provides substantiation for required labeling
(see below).
•ERP and EIRP measurements for FCC Parts 22 and 24, alternatively a full retest on
FCC Parts 22 and 24 can be performed.
•If used in a "mobile" application where the antenna is normally separated at least 20 cm
(7.9 in) from the human body during device operation, then an appropriate warning label
must be placed on the host unit adjacent to the antenna. The label should contain a
statement such as the following:
WARNING
RF exposure. Keep at least 20 cm
(7.9 in) separation distance from
the antenna and the human body.
•Host unit user manuals and other documentation must also include appropriate caution
and warning statements and information.
•If the FCCID for the modem is not visible when installed in the host platform, then a
permanently attached or marked label must be displayed on the host unit referring to the
enclosed modem.
For example, the label should contain wording such as:
Contains GSM/GPRS modem transmitter module
FCC ID: MIVGSM0308
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions: (1)
This device may not cause harmful interference, and (2)
This device must accept any interference received,
including interference that may cause undesired
operation.
OR
Contains FCC ID: MIVGSM0308
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions: (1)
This device may not cause harmful interference, and (2)
This device must accept any interference received,
including interference that may cause undesired
operation.

•Any antenna used with the modem must be approved by the FCC or as a Class II
Permissive Change (including MPEL or SAR data as applicable). The "professional
installation" provision of FCC Part 15.203 does not apply.

•The transmitter and antenna must not be co-located or operating in conjunction with any
other antenna or transmitter. Violation of this would allow a user to plug another
transmitter in to the product and potentially create an RF exposure condition.
WARNING
The transmitter and antenna must not be collocated
or operating in conjunction with any
other antenna or transmitter. Failure to observe
this warning could produce an RF exposure
condition.
2.2. Disclaimer
The information and instructions contained within this publication comply with all FCC, GCF,
PTCRB, R&TTE, IMEI and other applicable codes that are in effect at the time of publication.
Enfora disclaims all responsibility for any act or omissions, or for breach of law, code or
regulation, including local or state codes, performed by a third party.
Enfora strongly recommends that all installations, hookups, transmissions, etc., be performed by
persons who are experienced in the fields of radio frequency technologies. Enfora acknowledges
that the installation, setup and transmission guidelines contained within this publication are
guidelines, and that each installation may have variables outside of the guidelines contained
herein. Said variables must be taken into consideration when installing or using the product, and
Enfora shall not be responsible for installations or transmissions that fall outside of the
parameters set forth in this publication.
Enfora shall not be liable for consequential or incidental damages, injury to any person or
property, anticipated or lost profits, loss of time, or other losses incurred by Customer or any third
party in connection with the installation of the Products or Customer's failure to comply with the
information and instructions contained herein.
The Enabler IIIG platform is designed with features to
support a robust connection. There are instances
where the module performance is beyond the control
of the intended design. Integrated designs that require
24 by 7 operation must implement power control via an
external circuit or by implementing power management
as specified within this design guide.

4.6. General design guidelines for utilizing Enfora GSM modules
The following guidelines are provided in an effort to allow Enabler IIIG module users to successfully
implement their PCB layout to obtain the best performance. This includes the lowest possible EMI
emissions, maximum thermal conduction, mechanical integrity, and voice quality. The Enabler IIIG
module is a very compact, high performance design, yet it is easy to interface into the final product.
In order to realize its full potential, designers should pay close attention to ground structures, the
routing of RF and Digital traces, and the size of the power supply lines.
These design tips are strictly guidelines and are not
meant to be a complete list of items that guarantee
actual performance. Each application is different and
may require variation from these guidelines, however,
care should be given to utilize these sound engineering
principles whenever possible.

4.6.1.Advanced tips for an RF friendly layout
4.6.1.1. Ground Plane
To ensure the lowest possible EMI emissions and maximum thermal conductivity, it is
recommended that all metal tabs on the GSM module shield must be soldered down onto a
continuous ground plane that runs under the entire module. Ample ground vias should be
provided around the metal tabs to create a low impedance ground. It is recommended to
minimize the number of I/O and power traces and vias under the GSM module to allow for as
much ground plane as possible. An example of a good ground structure and pad layout is
shown below in Figure 1.
Figure 1 - Example of good ground plane for GSM modules
4.6.1.2. Thermal Relief
Because the ground plane acts as a large heat sink, it can affect the solderability of
components. A common method to reduce this effect is to use thermal relief around the pad
in question. However, great care must be taken when using thermal relief for high current or
high frequency applications
For example, a large thermal relief like the one shown in Figure 2 can serve the purpose for
general applications such as low current, low speed data lines, DC connections and audio
