Operation Description of SFM60R4(Rev1.0)
1. Introduction
The SFM60R4 is a quad mode module supporting Sigfox, BLE and GPS.
This Module able to transmit and receive messages using the SIGFOX network.
The typical applications can be used as a low power tracking device.
The application use GPS to determine location. It will then transmit the location information via SIGFOX. It also
will transmit other information like temperature, accelerometer, and so on.

3.2 Time base of the RF frequency
-SIGFOX
For Sigfox RF frequency, a TCXO(48MHz) is a clock reference.
-BLE
Using external 32.768 kHz crystal for RTC.
The 64 MHz crystal oscillator (HFXO) is controlled by a 32 MHz external crystal.
-GPS(GLONASS)
The RTC is driven internally by a 32.768 Hz oscillator, which makes use of an external RTC crystal.
For GPS(GLONASS) RF frequency, a TCXO(26MHz) is a clock reference.
3.3 Transmission
-SIGFOX
The Tx path produces a DBPSK-modulated signal. modulate RF signal generated by the synthesizer. The
modulated RF signal is fed to the integrated RX/TX switch and antenna interface and then out of the AX-SFUS1-01.
-BLE
The RADIO contains a 2.4 GHz radio receiver and a 2.4 GHz radio transmitter that is compatible with
Nordic's proprietary 1 Mbps and 2 Mbps radio modes in addition to 1 Mbps Bluetooth® low energy mode.

3.4 Receiver
- SIGFOX
The Rx path is able to receive 922.3MHz signal and the noise amplifier is built in the inside of the chip, it
amplifies the received signal by the low noise amplifier according to the receiving intensity, and the amplified
signal is converted into the digital signal through the ADC, Packets will be interpreted.
-BLE
The RADIO contains a 2.4 GHz radio receiver and a 2.4 GHz radio transmitter that is compatible with
Nordic's proprietary 1 Mbps and 2 Mbps radio modes in addition to 1 Mbps Bluetooth® low energy mode.
-GPS(GLONASS)
u-blox 8 GNSS chips are single GNSS receivers which can receive and track either GPS or GLONASS signals.
By default the u-blox 8 receivers are configured for GPS, including SBAS and QZSS reception. If power
consumption is a key factor, then QZSS and SBAS should be disabled.
-NFC
The NFCT peripheral (referred to as the 'NFC peripheral' from now on) supports communication signal
interface type A and 106 kbps bit rate from the NFC Forum.

FCC Part 15.19 / RSS-GEN Sec.8.4 Statements:
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.
Le présent appareil est conforme aux CNR d’Industrie Canada applicables 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.
FCC Part 15.21 statement
Any changes or modifications not expressly approved by the party responsible for compliance could void the
user's authority to operate this equipment.
RF Exposure Statement
The antenna(s) must be installed such that a minimum separation distance of at least 20 cm is maintained
between the radiator (antenna) and all persons at all times. This device must not be co-located or operating in
conjunction with any other antenna or transmitter.

OEM Responsibilities to comply with FCC Regulations
The module has been certified for integration into products only by OEM integrators under
the following condition:
- The antenna(s) must be installed such that a minimum separation distance of at least 20
cm is maintained between the radiator (antenna) and all persons at all times.
- The transmitter module must not be co-located or operating in conjunction with any other
antenna or transmitter except in accordance with FCC multi-transmitter product procedures.
As long as the two condition above is met, further transmitter testing may 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: In the event that these conditions can’t be met (for certain configurations or co-location
with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID can’t 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.
