# Introduction to Sigfox

## Sigfox in 5 minutes <a href="#sigfox-in-5-minutes" id="sigfox-in-5-minutes"></a>

Sigfox basically means 2 things:

1. Radio technology protocol
2. Worldwide radio network for the Internet of Things (IoT) using Sigfox radio technology

{% hint style="info" %}
**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.\\

## 1. **Radio technology**

* 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**.

## 2. **Worldwide radio network for the Internet of Things using the Sigfox radio technology**

* 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).

## Sigfox vs LoraWAN vs NB-IoT

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

Check out [this webinar](https://www.youtube.com/watch?v=vqHOyQK6jJ8), we found it very useful. And we've also written a [blog post on the comparison of the three technologies](https://simplehw.eu/blog/simplenews-1/post/5-reasons-why-we-don-t-do-our-devices-with-lora-or-nb-iot-tech-29).

## Sigfox training resources: Sigfox Support & Sigfox Build

1. [**Sigfox Support**](https://support.sigfox.com/) - a general knowledge base about Sigfox for anybody interested in the technology.
2. [**Sigfox Build**](https://build.sigfox.com/) - this is a learning resource intended for developers. Here you can find all the necessary information if you want to build your own devices or platform.
