This LPWAN Module GL6509 is a general purpose SMT module for sensor integration. Sensor
vendors can speed up their LPWAN integration by embedding this module in their designs. This
module will take care of the LPWAN communication with our LPWAN AP and cloud services.
There are different integration options: the sensor design can integrate this SMT module via AT
command set treating this module as a LPWAN modem; the interface can be via Modbus interface;
and the entire sensor be controlled by the MCU of the module through GPIO or I²C or UART.
This GL6509 Module complies with the LoRaWAN Class A protocol specifications. It integrates RF,
a Low-Power Long Range transceiver and an application MCU. Together with the integration to
our LPWAN gateway and back-end cloud service, making this a total IOT network solution.

The GL6509 module is based on LoRa technology to provide low power long range
communication using spread spectrum. This provides very high receive sensitivity enabling
communication with high interference immunity.
Using LoRa modulation, depending on the spreading factor (SF), GL6509 can achieve system
receiver sensitivity of -137.5 dBm.

Federal Communication Commission 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 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 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.
FCC Caution: Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate this equipment.
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.
IMPORTANT NOTE:
Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with minimum distance
20cm between the radiator & your body.
This transmitter must not be co-located or operating in conjunction with any other antenna or
transmitter.
Country Code selection feature to be disabled for products marketed to the US/CANADA
Operation of this device is restricted to indoor use only
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, and
2) The transmitter module may not be co-located with any other transmitter or antenna,
As long as 2 conditions above are met, further transmitter test 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
IMPORTANT NOTE
In the event that these conditions can not be met (for example certain laptop configurations or colocation with another transmitter), then the FCC authorization is no longer considered valid and
the FCC ID can not 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 authorization.
End Product Labeling
This transmitter module is authorized only for use in device where the antenna may be installed
such that 20 cm may be maintained between the antenna and users. The final end product must
be labeled in a visible area with the following: “Contains FCC ID: MXF-WMDS-203”.
Manual Information to the End User
The OEM integrator has to be aware not to provide information to the end user regarding how to
install or remove this RF module in the user’s manual of the end product which integrates this
module.
The end user manual shall include all required regulatory information/warning as show in this
manual.
