Trials Outperform Existing Solutions in Data-Rate Flexibility & Transmission Range, Technology Especially Suitable for Massive Machine-Type Communication Systems
GRENOBLE, France – June 03, 2018 – Leti, a research institute of CEA Tech, today announced that field trials of its new Low Power Wide Area (LPWA) technology, a waveform tailored for Internet of Things (IoT) applications, showed significant performance gains in coverage, data-rate flexibility and power consumption compared to leading LPWA technologies.
“Leti’s Turbo-FSK receiver performs close to the Shannon limit, which is the maximum rate that data can be transmitted over a given noisy channel without error, and is geared for low spectral efficiency,” said Vincent Berg, head of Leti’s Smart Object Communication Laboratory. “Moreover, the waveform exhibits a constant envelope, i.e. it has a peak-to-average-power ratio (PAPR) equal to 0dB, which is especially beneficial for power consumption. Turbo-FSK is therefore well adapted to future LPWA systems, especially in 5G cellular systems.”
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
