Latest Patents

One of Ludovic Champion's latest patents is a "Wireless communication system with macro diversity." This system comprises one or several nodes equipped with a wireless radio interface that transmits digital messages modulated in the form of frequency chirps, such as LoRa-modulated radio signals. The system allows messages to be received simultaneously by multiple base stations, with a server designed to divide the frames by the diverse stations and recombine a corrected frame for the intended recipient based on error codes. This innovation includes a feature where base stations adapt their timing error compensation strategy when error codes indicate message corruption.

Another notable patent is the "Signal concentrator device." This gateway device features a baseband processor that processes multiple signals carrying digital information modulated in the form of chirp signals. The chirp signals can be either base chirps or modulated chirps, with the device capable of simultaneously demodulating several signals received at the same frequency, exhibiting different bitrates. This advancement enhances the efficiency and reliability of wireless communication systems.
