SIGFOX is an IoT-dedicated network that guarantees a high level of service and reliability. Its easily integrated solution enables years-to-decades of battery life for connected devices in all business and industry sectors. SIGFOX uses a UNB (Ultra Narrow Band) based radio technology to connect devices to its global network. The use of UNB is key to providing a scalable, high-capacity network, with very low energy consumption, while maintaining a simple and easy to rollout star-based cell infrastructure.

The network operates in the globally available ISM bands (license-free frequency bands) and co-exists in these frequencies with other radio technologies, but without any risk of collisions or capacity problems. SIGFOX currently uses the most popular European ISM band on 868MHz (as defined by ETSI and CEPT) as well as the 900MHz that will be used in USA and Australia.

Communication on SIGFOX is secured in many ways, including anti-replay, message scrambling, sequencing, etc. The most important aspect of transmission security is however that only the device vendors understand the actual data exchanged between the device and the IT systems. SIGFOX only acts as a transport channel, pushing the data towards the customer’s IT system. An important advantage provided by the use of the narrow band technology is the flexibility it offers in terms of antenna design. On the network infrastructure end it allows the use of small and simple antennas, but more importantly, it allows devices to use inexpensive and easily customisable antennas.

The SIGFOX protocol is compatible with existing transceivers and is actively being ported to a growing number of technical platforms including the Radiocrafts footprint modules and the Libellum IoT Smart Sensing platforms, both supported by M2M Connectivity.
