Y-Lynx takes with succes the virtual-challenge for the second year

Y-Lynx, a provider of embedded solution for low-power wireless links, and the MIS (eMbedded Information System) Institute from Yverdon and in partnership with Leclanché (Batteries supplier), CeTT (Center for Engineering and Technology Transfer), HEIG-VD (Haute Ecole d'Ingenierie et de Gestion du Canton de Vaud) will be showcasing a high-performance tracking solution for the second consecutive year, during the 2006 Julius Baer Challenge from 6th of May to 17th September on internet.

How it works?:

For this second year, Y-Lynx and MIS institute concentrate their efforts on the wireless communication and on the internet interface. A new technology has been used to broadcast the virtual race on the web and the user interface has been made by keeping in mind the conviviality. For the radio communication the new Radio Modem from Y-Lynx has been used, the TRM8053-500, with his 500mW output power more than 40km has been reached during the "Bol d'Or" race. A server was placed on the "signal de Bougy" above Lausanne, from this place the all Leman lack was on the range. The solution used the powerful LibIC implemented inside the radio modem. The system is based on a "Server /Clients" topology and to avoid RF collisions, a mix between TDMA and FDMA protocol has been used. The Server sends every second a synchronisation trame to the 8 boats but also to the bouys. Based on this time stamp, each boats send his GPS information into a dedicated time slots. All the GPS information coming from boats and bouys are received by the server in less than 1 seconds. Thanks to this two advance technologies (internet and radio communication) the "web spectator" can follow the race in real time.
