Expérimente en Méditérannée, SeaRake, la nouvelle génération des MobiRake Wi50-Diversity. Ces radio 5.4 GHz de 3 Watts se caractérisent par l'usage d'antennes à diversité d'espace, à diversité de champ et en polarisation double circulaire "RHCP" et "LHCP« , pour un usage NLOS.Ce concept de radio et d'antennes est destiné à neutraliser les effets de la mobilité, ainsi que les mouvements aléatoires des navires.
