Introduction to Sigfox
Sigfox basically means 2 things:
- 1.Radio technology protocol
- 2.Worldwide radio network for the Internet of Things (IoT) using Sigfox radio technology
Imagine the Internet as a human body - The head is the traditional internet as we know it. Email, social networks, big data, visualizations, etc. But the head/internet has a very limited capability of understanding the physical world around us. It lacks the human senses. This is where IoT devices come into play. IoT devices are the senses of the traditional internet connecting the Internet to the physical world. The touch, temperature, sight, noise, etc. In order to transfer this information from the senses to the brain, you need to have neural lines in your body. Sigfox is nothing else than a neural system transferring information from the sensors/IoT devices to the Internet as we know it.\
- Very different from Bluetooth, GSM, LTE, or WiFi.
- Doesn't use any physical SIM card.
- Allows devices to work on very small batteries with a lifespan of 10 to 20 years. The devices are low-cost and small.
- Transfers received messages to the Internet directly, without having to use local hardware/gateways - this is done through hundreds of radio towers deployed nationwide.
- Emits up to 200 km.
- Secure and impossible to jam, the protocol is publicly defined.
- Supported by hundreds of manufacturers and devices.
- Works worldwide with roaming.
- Physical network with tens of thousands of radio towers worldwide.
- A managed network with strict SLA, reliability, and security monitoring.
- Being built up and supported by 60 Sigfox operators (one in each country) and currently covers one billion people.
- Centralized and unified security.
- Very simple and unified access to all data from the devices.
- Paid per device and according to the number of messages from the devices (approximately 0.1 USD to 1 USD monthly per device).
So how does Sigfox compare to the other Low Power Wide Area Networks (LPWAN) technologies? Each of them is ideal for different applications and use cases.
- 1.LoRa by Semtech for factory automation
- 2.NB-IoT for PoS payment terminals
- 3.Sigfox for tracking or utility measurements
