1 System features of Mobile Maritime Data Solution: Licensed free – 4.9 ~ 6.0 GHz High output power of Radio, up to 3W NO LOS up to 16 KM LOS up to 60 KM LHCP/RHCP sector antenna supporting Rx diversity @ mobile end perfect 2ppm frequency stability for mobility CPE without near-far end problem under PTMP configuration Without packets collision @ CPE end Mobile Maritime Data Solution – e-rake.fr Coast RHCP Base Station Boats diversity radio antennas 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. MobiRakedouble circulaire Ce concept de radio et d'antennes est destiné à neutraliser les effets de la mobilité, ainsi que les mouvements aléatoires des navires.
