VT is the exclusive operator of the Sigfox network in Ireland. This nationwide Internet of Things (IoT) network provides the lowest power, lowest cost connectivity for the most common use of connected objects — simple sensors and devices. We work with manufacturers and developers to connect their creations.

What is the Internet of Things?

The Internet of Things (IoT) refers to connecting everyday objects to the internet — everything from cars to simple sensors. Expert estimates vary, but the analyst firm Gartner believes there will be more than 20 billion connected devices by 2020. The majority of these will be very simple and require only small amounts of bandwidth to operate.

Connect to the cloud straight out of the box

How Does Sigfox Work?

Each device or sensor sends its message directly to one or more of the network base stations, which then upload the information to the Sigfox cloud. From there, the data is pushed to the customer’s cloud, mobile app or web platform. The entire process is virtually instantaneous.

Data Optimization Means Low Connectivity Cost

Cellular connectivity, such as 3G, is designed to transport large amounts of information — something that isn’t necessary for many Internet of Things (IoT) devices. Sigfox is optimized for simple sensors and devices, which make up the majority of the IoT. This means that end users don’t have to pay large costs for data capacity their devices will never need. 

Simple & Energy Efficient

Traditional cellular networks are complicated and power hungry. The Sigfox network uses simple protocols, allowing devices to be four to six times smaller, and is up to 300 times more energy efficient than traditional networks. Many Sigfox-enabled products regularly send small pieces of information, while others sleep until an event triggers them, causing a message to be sent through the network to the Sigfox cloud. This allows devices to preserve battery life, sometimes operating for nearly a decade on only AA batteries.

Reliable & Secure

The Sigfox network is extremely resistant to tampering, and has yet to be jammed in the real world. It isn’t vulnerable to the devices that jam traditional cellular networks, and each message is sent in triplicate to ensure it is received. Devices have their own unique keys, which are sent with every message so the network can identify the module. Each message is uniquely scrambled so the system can recognize any attempt to artificially repeat them.

Two-way Connectivity

Not only can your device talk to the cloud and send you information, but Sigfox also has downlink capability, allowing you to send information and instructions to your devices. For example, this would allow you to change the settings of a device remotely.

Long-range Coverage

VT’s ultra narrow band frequency can travel for great distances, providing excellent coverage across the country, with many areas served by three or more base stations. In real-life conditions, Sigfox signals have been found to travel hundreds of kilometres. The coverage even goes 150km out to sea.

Base Station Network Offers Freedom to Roam

Sigfox technology operates on a base station system. Each device communicates directly with a base station, which in turns uploads the information to the cloud. This design means that devices can roam anywhere there is a network, which currently includes 32 countries across the world, including nationwide in Ireland. There is also no need for users to buy equipment for their Sigfox devices to operate. They are connected to the network straight out of the box, making for easy setup.
