UnaBiz, a provider and integrator of Massive Internet of Things (IoT) services, has unveiled a significant performance enhancement on Sigfox 0G technology, slashing device energy consumption by up to 18 times. This transformative improvement aims to provide a substantial efficiency boost for Sigfox-based solutions, benefiting developers, 0G Operators, and major customers alike.
At the centre of this advancement lies the integration of a 600bps data rate across its global 0G network, along with the introduction of the N=1 repetition mode. Together, these innovations enable devices to operate with unparalleled efficiency, reducing energy consumption by up to 18 times compared to the previous standard of 100bps with N=3 repetition mode:
- By incorporating the higher 600bps data rate alongside the existing 100bps infrastructure, solution makers can achieve a sixfold reduction in energy consumption and enhanced transmission quality, particularly when devices are in motion
- Opting for minimal repetition – sending only two frames or even one frame instead of three – enables solution makers to enjoy additional energy savings ranging from 33% to 66%
These optimisations not only significantly extend battery life for sensor solutions, enhancing reliability and longevity while unlocking new business opportunities, but also introduce flexibility in battery management for device and solution designers. Furthermore, they enhance performance for use cases requiring radio transmission efficiency beyond current implementations.
“With this technology update, we offer enhanced flexibility for our partners to optimise their solutions. Device battery requirements can vary greatly depending on needs like Facility Management, Metering, and Asset Tracking. With our latest network and device library updates, solution designers can now easily balance device lifetime and network performance for their specific use cases. Seamless transmission option selection eliminates the need for network resync, unlocking broader possibilities with Sigfox 0G technology,” explained Nicolas Chalbos, Head of Sigfox Innovation at UnaBiz.
As with most IoT technologies, improvements in power efficiency bring advantages and considerations:
- Transmitting at 600bps enhances communication speed and optimises the spectrum used by Sigfox 0G technology, but reduces the transmission budget by 8dB, impacting the range at which messages are received by Sigfox gateways
- Reducing message repetition from the default three to one also reduces spectrum use and overall power needed to transmit, but may increase the possibility of incomplete data reception in areas with weaker network coverage
Solutions designers, particularly those implementing 600bps and/or N=1 configurations, are encouraged to verify data transmission reliability in their deployment areas. If additional coverage is required, global 0G network operators provide assistance and various solutions for coverage extension.
Alexis Susset, CTO of UnaBiz, stated: “We are continuously evolving Sigfox 0G technology both for enterprises and the broader market in general. The new enhancements aim to improve UnaBiz’s technological ability to address IoT solution needs that rely on the key strength of our Sigfox 0G technology.
“Enabling 600bps data transmission and releasing our open-source device library, which includes options to control data transmission repetition, not only enhances energy management for devices but also improves reliability in use cases such as logistics, where the devices are transmitting while moving. We look forward to continuing to empower businesses and industries to address their challenges with our frugal, cost-effective, and energy-efficient technology and solutions.”
