  2. Caractéristiques de la mobilité eRake Radio FFC: • Système e MESH propriétaire • Système Wireless Rake propriétaire @ IEEE 802.11n Hardware Far Field communications • Roaming ( < 20ms fast handover) • Mobilitée 200Km/hr @ 5.4 GHz • Recherche automatique du meilleur chemin • Hautes performances en mobilité @ IEEE 802.11n Base Hardware • Clef d’encryption dynamique • Débit adaptatif • Les clefs du succès de la Mobilité : • Un bon maillage de la couverture. • Une Topologie MESH (Ethernet Shortcut..) • Des Radio & antennes cellulaires adaptées • DesRadio & antennes mobiles spécifiques • Des accès WiFi standard e-rake.us.com

  3. eRake Mobility Features: • Working under eMESH system • Proprietary Rake System @ IEEE 802.11n Hardware • Wireless seamless handover( < 20ms fast handover) • 200Km/hr High Speed Mobility • Auto Forwarding Path Discover • High Performance Mobility System @ IEEE 802.11n Based Hardware • Wireless Dynamic Key Encryption • Wireless Rate Adaptation • The Key of Success for Mobility: • Good MESH Coverage • Appropriate MESH Topology (Ethernet Shortcut..) • Appropriate Antenna Deployment • Appropriate Antenna of Mobility Station e-rake.us.com

  4. Device roles of mesh architecture: MG (MESH Gateway) Wire to connect to LAN or WAN MP (MESH Point) Wireless connections to form wireless backbone MAP (MESH Access Point) To provide services to 1. Standard WiFi devices(such as NB, Smartphone…) 2. MESH mobility device(MSTA) MSTA (Mobility Station) MESH Mobility End Device e-rake.us.com
