1 INTRODUCTION
The Sentrius™ RG191-M2 LoRaWAN Concentrator Card combines Laird’s long-standing expertise in optimized RF
design with the emerging LoRaWAN ecosystem. The Sentrius™ RG191-M2 card enables OEMs to integrate a
high-performance, certified LoRaWAN gateway interface to any Linux-based platform. Laird’s optimum
hardware solution expands upon Sentrius™ drivers and reference design for improved RF performance.
Comprehensive integration and design services for a custom gateway are also available via Laird’s dedicated
Engineering Services team and qualified LoRa antenna solutions are available from Laird.
2 OVERVIEW
The module is designed around the Sentrius™ SX1301 digital baseband chip with an integrated LoRa concentrator
IP, which is designed to perform high performance gateway function in the ISM band. The RF frontend consists
of two of SX1257, high performance digital I and Q modulator/demodulator transceiver chips. The RF front-end
is terminated with standard U.FL connector. The board form factor and connector pinout are designed to conform
to M2.COM specifications. The card requires a single 5-volt supply and it generates its power supply requirements
on-board. Standard SPI communication, reset, and power supply to the board are provided through a 75-position
host interface connector.

6 FCC AND IC REGULATORY STATEMENTS
Model
US/FCC
CANADA/IC
RG191-M2
SQG-1001
3147A-1001
The OEM must follow the regulatory guidelines and warnings listed below to inherit Laird’ modular approval.
The RG191-M2 holds full modular approvals and has been certified for integration to products only by OEM
integrators under the following conditions:
1. The antenna(s) must be installed such that a minimum separation distance of 20 cm is always maintained
between the radiator (antenna) and all persons.
2. The transmitter module must not be operating in conjunction with any other antenna or transmitter, except
in accordance with FCC multi-transmitter product procedures.
If the two conditions above are met, further transmitter testing will not be required. However, the OEM
integrator is still responsible for testing their end-product for any additional compliance requirements required
with this module installed (for example, digital device emissions, PC peripheral requirements, etc.).
IMPORTANT NOTE: If these conditions cannot be met (for certain configurations or co-location with another
transmitter), then the FCC and Industry Canada authorizations are no longer considered valid and the FCC ID and
IC Certification Number cannot be used on the final product. In these circumstances, the OEM integrator will be
responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC and
Industry Canada authorization.
Power Exposure Information
Federal Communication Commission (FCC) Radiation Exposure Statement:
To comply with FCC RF exposure limits for general population/uncontrolled exposure, the antenna(s) used for
this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and
operating in conjunction with any other antenna or transmitter.
OEM Responsibilities
WARNING: The OEM must ensure that FCC and Industry Canada labelling requirements are met. This includes a
clearly visible label on the outside of the OEM enclosure specifying the appropriate Laird FCC
identifier for this product.
Contains FCC ID: SQG-1001
Contains IC: 3147A-1001
The OEM of the RG191-M2 module must only use the approved antenna(s) listed above (TBD),
which have been certified with this module. The OEM integrator must not provide information to
the end user regarding how to install or remove this RF module or change RF related parameters in
the user manual of the end-product.
The user manual for the end-product must also include the following information in a prominent
location:
To comply with FCC and Industry Canada RF exposure limits for general population/uncontrolled
exposure, the antenna(s) used for this transmitter must be installed to provide a separation distance
of at least 20 cm from all persons and operating in conjunction with any other antenna or
transmitter, except in accordance with FCC multi-transmitter product procedures.

If the size of the end product is larger than 8x10cm, then the following FCC part 15.19 statement has
to also be available on visible on outside of device:
The enclosed 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
Label and text information should be in a size of type large enough to be readily legible, consistent
with the dimensions of the equipment and the label. However, the type size for the text is not
required to be larger than eight point.
CAUTION: The OEM should have their device which incorporates the RG191-M2 tested by a qualified test
house to verify compliance with FCC Part 15 Subpart B limits for unintentional radiators.
WARNING: Changes or modifications not expressly approved by Laird could void the user’s authority to
operate the equipment.
FCC Interference Statement
This equipment 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
radiate 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 an 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 correct the interference by one or more of the following measures:
▪ Re-orient or relocate the receiving antenna
▪ Increase the separation between the equipment and the receiver
▪ Connect the equipment to 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.
FCC Warning:
“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.
Industry Canada (IC) Warning:
This device complies with Industry Canada license-exempt RSS standard(s). 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.
French equivalent is:
Le présent appareil est conforme aux CNR d'Industrie Canada applicable aux appareils radio exempts de licence.
L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas produire de brouillage, et
(2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est
susceptible d'en compromettre le fonctionnement.

IMPORTANT NOTE
If these conditions cannot be met (for example certain laptop configurations or co-location with another
transmitter), then the Canada authorization is no longer considered valid and the IC ID cannot be used on the
final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end-product
(including the transmitter) and obtaining a separate Canada authorization.
NOTE IMPORTANTE
Dans le cas où ces conditions ne peuvent être satisfaites (par exemple pour certaines configurations
d'ordinateur portable ou de certaines co-localisation avec un autre émetteur), l'autorisation du Canada n'est
plus considéré comme valide et l'ID IC ne peut pas être utilisé sur le produit final. Dans ces circonstances,
l'intégrateur OEM sera chargé de réévaluer le produit final (y compris l'émetteur) et l'obtention d'une
autorisation distincte au Canada.
Le produit final doit être étiqueté dans un endroit visible avec l'inscription suivante: " RG191-M2 Contient des
IC: 3147A-1001".
