Teaching students in University

The University of Versailles is one of the known Universities in Ile-de-France. It was the former part of also well-known Paris VI technical University in the center of Paris. University of Versailles is situated in the former royal city Versailles close to the Versailles Chateaux. University proposes multiple faculties and disciplines, including physics, mathematics, informatics, medicine, mobile communications, and other. Idea was to present the industry know how concerning the mobile protocols, 3GPP organization, modems

M2M mobile projects

The Machine to Machine solutions have been developed in the former Wavecom company, called actually Sierra Wireless. The difference between the handset manufacturers is the development of Machine to Machine solution; the chip is less sensitive for the market and stays sufficiently stable to the conjuncture. The product of Sierra Wirelee since 2010 is the ASIC based chips using the 2G (GSM/GPRS/EDGE) / 3G protocols to communicate from machine to machine. The typical applications are

Project on GNSS in Ubiscale

Purpose of the GNSS project was to propose the solution integrated in the chip that fits 3 requirements: (1) – GPS compatibility, (2) – Galileo compatibility, (3) – IoT compatibility. Under the IoT is considered the protocol of data transmission, like Lora for the long range. Potential applications could be the tracking of rail freight, tracking of domestic animals like dogs and cats, tracking the ships and many other applications. So, briefly clients could be

Projects in Oil industry

This project WiCOM has been developed in Schlumberger in 2005. Its purpose was the telemetry between downhole receiver and the surface of the land in two senses: Uplink and Downlink. In Uplink we transmit the temperature, pressure and the voltage measurements. In Downlink there are two possibilities of using: activation of some mode or receiver and activation of some explosion to ensure the delivery of oil from some side pocket. In any way the two

3GPP standardization project

3GPP standardization is the set of international committees that controls the development of different standards of mobile phones: 2G (GSM/GPRS/EDGE), 3G (UMTS), 4G(LTE), 5G. 3GPP englobes different groups, notably of physical layer, L2, L3 protocols, etc. People who work in these sections are normally the recognized experts in their domains from the famous telecommunication manufactures like Nokia, Samsung, Motorola, Huaway, SonyEricsson, etc. The purpose of the meeting is to develop the transmitter algorithms and to

Chess FIDE anti-cheating project

FIDE is the main organization unifying millions chess players and hundreds grandmasters in the World. Since the computer managed to battle the world champion (Kasparov and then Kramnik), a big temptation exists for every chess player: to cheat by means of technical devices (computers linked with radio modems and micro radio receptors). That is really not fair play, but some cases arrive from time to time even in big tournaments. To eliminate this possibilities exist

Smart grids water/gaz/electricity projects

This project has been realized at Itron, the former Schlumberger department between 2011 and 2016. The domain of Itron activity is gaz/water/electricity metering. Right now the smart grids are used. So the products are gaz/water/electricity counters. This industry suppose to make two parts of the activity: (1)- metering itself – counting water cubes, kilowatts consumptions and (2) – transition of this information to base station. The most part of communication for 3 meters are carried

Video compression and video clips projects

Video compression has been developed since the 2002 in France Telecom spin off called Envivio. At that moment the most attractive video compression algorithm was considered to be video codec H.264 including both video compression and audio codecs parts. This company was the pioneer in France in the field of video compression. For its solution the research results and cooperation with France Telecom have been widely used. Technical realization of project. The following features have

Project on Voice over IP

In the beginning of the 21 th century very interesting project has been developed in Terayon communication systems, that became later Motorola. The Terayon Voice over IP solutions were almost the first in the world complete hardware + software solution. Large spectrum of applications was open for such the revolution technology. The telephone signal is supposed to be digitized and then transformed to IP packets. Instead telephone cables the information is transmitted over TCP/UDP/IP everywhere

OFDM research projects

The European project around the OFDM signals has been developed in France Telecom R&D (actually Orange labs) in Rennes. System of signals has been simulated under COSSAP system Multi path propagation models have been used for transmitter – receiver simulations. Different team worked with multiple annex problems around OFDM signals: turbo coding, source coding, PAPR reduction, efficient equalizers, etc.. Multiple patents (notably on Turbo coding) have been created that time in FT R&D. The centre
