This document provides an overview of Sigfox and its low-power wide-area network technology for connecting IoT devices. Sigfox uses an ultra-narrowband radio technology that allows low-cost, low-power devices to transmit small amounts of data over long ranges. Key aspects include its public network architecture, security features to authenticate devices and messages, and the ability for devices to connect directly to Sigfox's cloud platform without any pairing or additional infrastructure. The document outlines how to build Sigfox-compatible devices, connect them to the global Sigfox network, and manage devices and data through Sigfox's cloud services.

PHILOSOPHY OF SIGFOX NETWORK THE TECHNOLOGY TO MEET THE IOT STRATEGY: - LOWEST TCO - OUT OF THE BOX CONNECTIVITY - LOWEST ENERGY - GLOBAL REACH FARTHEST SATELLITE FROM EARTH USES UNB BPSK Lowest TCOLowest Energy Bidir is device initiated Sleep time maximized Small messages 14 bytes of header + 12 bytes max of payload Use existing chipsets Global reach Unlicensed spectrum ISM band: ETSI 868Mhz / FCC 902Mhz No synchronization with base stations Sleep time maximized Simple processing Long range to reduce number of base stations Large link budget = 160dB High capacity network for scalability Low radiated power 25mW @ 100bps ETSI 150mW @ 600bps FCC Out of the box connectivity No pairing Public network Strong resistance to interference Ultra Narrow Band BPSK is the way to go
GUARANTEE OF DELIVERY DIVERSITY REPLACES ACKNOWLEDGEMENT DIVERSITY Each message sent over 3 radio frames - Time diversity - Frequency diversity COLLABORATIVE NETWORK Space diversity SIGFOX cloud will receive the 3 radio frames 9 times freq diversity time diversity
UNB RESISTANCE TO INTERFERENCE UNB BEST TECHNOLOGY AGAINST INTERFERER UNB CONCENTRATES THE ENERGY At equal power UNB concentrates energy in a very small bandwidth = higher power spectral density UNB REDUCES CHANCES OF COLLISION WITH INTERFERER Small bandwidth reduces probability of collision with high power interferer SIGFOX + conventional signals at same spectrum and power no loss COLLABORATIVE NETWORK MITIGATES INTERFERER IMPACT Having 3 base stations at 3 different locations reduces the impact of interferers in the message delivery
HIGH CAPACITY CAPACITY MEASURED ON THE FIELD UNB IS BEST SUITED FOR HIGH CAPACITY ULTRA NARROW BAND ALLOWS HIGH CAPACITY @ 10message/day/device = 1.8M devices per base station 200 simultaneous messages within a 200kHz channel Future proof : 2M messages per base sta8on and aGer : cell size reduc8on, add another 200kHz channel
UNB VS SPREAD SPECTRUM (SS) BETTER RESISTANCE TO INTERFERER NO COLLABORATIVE NETWORK HIGHER CAPACITY UNB BETTER RESISTANCE TO INTERFERER Interferers in ISM band : SS CANNOT BENEFIT OF THE COLLABORATIVE NETWORK SS has to be a point to point communication Different devices using the same spreading code with different base stations will interfere each other UNB HAS HIGHER CAPACITY - Can be very high power FCC req is P<4W - Are hoping fast FCC req is less than 400ms Chances of having a blocking interferer in SS are higher than UNB UNB vs SS For same bandwidth more capacity
