FCC Regulations:
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.
This device has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the
FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiated radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation If this equipment does cause harmful interference
to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged
to try to correct the interference by one or more of the following measures:
-Reorient or relocate the receiving antenna.
-Increase the separation between the equipment and receiver.
-Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
-Consult the dealer or an experienced radio/TV technician for help.
Caution: Changes or modifications not expressly approved by the party responsible for compliance could void the user‘s
authority to operate the equipment.

RF Exposure Information
This device is intended only for OEM integrators under the following conditions:
(1) The antenna must be installed such that 20 cm is maintained between the antenna and users,
(2) The transmitter module may not be co-located with any other transmitter or antenna.
(3) To comply with FCC regulations limiting both maximum RF output power and human exposure to RF radiation, the
maximum antenna gain including cable loss in a mobile exposure condition must not exceed:
Standalone Condition:
。8.0 dBi in 700 MHz Band
。8.0 dBi in 850 MHz Band
。5.0 dBi in 1700 MHz Band
。7.5 dBi in 1900 MHz Band
Assuming collocated with a WLAN transmitter with maximum 27 dBm average EIRP power
。7.0 dBi in 700 MHz Band
。5.0 dBi in 850 MHz Band
。5.0 dBi in 1700 MHz Band
。7.5 dBi in 1900 MHz Band
Remark: This assumption is not valid if the output power of the collocated WLAN transmitter is higher than 27 dBm.
IMPORTANT NOTE:
This module is intended for OEM integrator. The OEM integrator is still responsible for the FCC compliance requirement
of the end product, which integrates this module. 20cm minimum distance has to be able to be maintained between
the antenna and the users for the host this module is integrated into. Under such configuration, the FCC radiation
exposure limits set forth for an population/uncontrolled environment can be satisfied.
Any changes or modifications not expressly approved by the manufacturer could void the user's authority to operate
this equipment.
USERS MANUAL OF THE END PRODUCT:
In the users manual of the end product, the end user has to be informed to keep at least 20cm separation with the
antenna while this end product is installed and operated. The end user has to be informed that the FCC radio-frequency
exposure guidelines for an uncontrolled environment can be satisfied. The end user has to also be informed that any
changes or modifications not expressly approved by the manufacturer could void the user's authority to operate this
equipment. If the size of the end product is smaller than 8x10cm, then additional FCC part 15.19 statement is required

1.Introduction
The M18Q2 is a Cat. 4 LTE modem which incorporates an application CPU subsystem and a host of
peripheral interfaces and functions uniquely designed to address the power/performance/cost
requirements of IoT and M2M applications. The chip is based on Qualcomm’s MDM architecture which
offers OFDMA-related software based signal processing capabilities that significantly exceed traditional
communications ARM cores.
The CPU subsystem features a high performance Cortex A7 microprocessor running a Linux OS with a
variety of host interfaces including USB 2.0, SGMII, SPI, UART, PCM, I2C, HSIC, USIM & SDC. The module
supports integrated VoLTE functionality, with a variety of narrow- and wide-band CODECs and full IMS
signaling.
