Latest Patents

One of her latest patents is a "Method for authenticating data packets received by a station of a digital telecommunications system." This method involves authenticating data packets transmitted by terminals, which successively send packets in various frequency bands. The process includes measuring the frequency band of the received packet, extracting an identification code, and determining a theoretical frequency hop based on the associated sequence. The method ultimately assesses whether the packets were transmitted by the correct terminal based on frequency hop deviations.

Another notable patent is the "Method for synchronizing time measurements carried out in a radio communication network for geolocation purposes." This invention outlines a system for forming an asynchronous communication network that enables the geolocation of client transmitters. It utilizes stationary reference transmitters with known positions, which transmit specific beacon signals. The geolocation process employs multilateration by analyzing the time differences in signal arrival at various base stations.
