Operation Description of SFM60R2(Rev1.0)

1. Introduction

The SFM60R2 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. Operational Description

-SIGFOX

SIGFOX able to transmit and receive messages using the SIGFOX network.

This module address the RC2(North America).

-BLE

Bluetooth 4.2 optimized for low-power applications.
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)

The application use GPS(GLONASS) to determine location. It will then transmit the location information via
SIGFOX. It also will transmit other information like temperature, accelerometer, and so on.

-NFC

Type 2 near field communication (NFC-A) tag with wakeup-on-field and touchto-pair capabilities

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.
