Question 1

What is 0G?

Accepted Answer

What is 1G 2G 3G 4G and 5G? The ‘G’ here stands for the Generations of mobile network. 0G or otherwise known as ‘zero generation’ is essentially about using radio telephone, that is pre-cellular.

Today 0G network is used to represented Sigfox, but it could also be used to represent an array of Low Power Wide Area Network (low-bandwidth wireless network) that is specifically designed to connect simple, low-powered IoT devices to the Internet, cost efficiently, at a massive scale in the future.

Question 2

Why go for low bandwidth when there is high bandwidth 4G (even 5G) network available?

Accepted Answer

There are very different use cases for such a low bandwidth network. Low bandwidth network’s main application is in sensing modules for data collection and analytics which are measured in bytes. This provides cost savings up to 90% as compared to the more expensive cellular 4G & 5G networks.

Question 3

Will my devices work abroad?

Accepted Answer

Any device equipped with Sigfox proprietary chipset will be able to ‘roam’ freely in countries with an operational Sigfox 0G network. There are currently more than 70 countries on the list.

Question 4

How secure is the Sigfox 0G network?

Accepted Answer

The unique thing about this network is that there is no synchronization between base station and device. Instead, the device broadcasts radio signals to multiple base stations close by through random frequency. This means that hackers would not be able to gain access into Sigfox 0G network backend. Furthermore, there is a restricted downlink and devices choose when to communicate and at which frequency, which protects it from hackers sending targeted malicious commands.

Question 5

Can we run a cyber attack by hacking a Sigfox 0G technology device?

Accepted Answer

-No. Sigfox 0G technology devices do not have an IP address. They are not connected to the Internet. They cannot be used as a vector of attack of a global system. What happened with baby monitors (massive DDoS attack on Dynn servers) could not, by nature, happen through Sigfox devices.

-Traditionally Sigfox enabled devices can send 12 bytes at a time and receive up to 32 bytes a day >> downloading malware on Sigfox 0G technology devices becomes impossible. In 2023, UnaBiz opened up the Sigfox library to allow developers to customised their solutions.

Developers can now adapt the memory footprint of their solutions based on use cases, be it advanced communication devices that require bi-directional communication, or simple IoT devices that require uplink-only communication.

They can even determine the execution mode (asynchronous/blocking), and the payload size, among other features. With “Open Library”, everyone can choose their features in the Sigfox 0G device library and maybe even contribute to the new features of the library!

Question 6

What are the Sigfox network specifications?

Accepted Answer

Sigfox 0G network operates on license-free sub-GHz ISM band using Ultra Narrow Band (UNB) modulation to exchange radio messages over the air. Messages are transferred at a data rate of 100 or 600 bits/s, depending on region. The combination of UNB modulation and low bit rate allows the network to achieve high network capacity and high sensitivity of its receivers, enabling long range transmission.

Question 7

I have 1,000,000 devices, do I have to conduct maintenance for them over the years?

Accepted Answer

Thankfully no. These connected devices are always designed to run seamlessly in the background for years or decades without the need for human interference. You can update devices wireless through the cloud network. This takes out the cost of maintenance of running so many devices.

Question 8

Is there coverage indoor? How can indoor coverage be improved?

Accepted Answer

Sigfox 0G network has its limitations indoor. To ensure good coverage indoor, you may purchase Mini base stations from UnaBiz. For the best network option based on your use case, please contact us directly.
