2 Caractéristiques de la mobilité eRake Radio FFC:
Système e MESH propriétaire Système Wireless Rake IEEE n Hardware Far Field communications Roaming ( < 20ms fast handover) Mobilitée 5.4 GHz Recherche automatique du meilleur chemin Hautes performances en IEEE n 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 e MESH system Proprietary Rake IEEE n Hardware Wireless seamless handover( < 20ms fast handover) 200Km/hr High Speed Mobility Auto Forwarding Path Discover High Performance Mobility IEEE n 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:
Ethernet to LAN / WAN (TCP-IP) Wireless to MESH Network (MESH) MG (MESH Gateway) Wire to connect to LAN or WAN Wireless to MESH Network (MESH) MP (MESH Point) Wireless connections to form wireless backbone Wireless to MESH Network (MESH) Wireless to Service (MESH / TCP-IP) MAP (MESH Access Point) To provide services to 1. Standard WiFi devices(such as NB, Smartphone…) 2. MESH mobility device(MSTA) Wireless to MESH Network (MESH) Ethernet to LAN (TCP-IP) MSTA (Mobility Station) MESH Mobility End Device e-rake.us.com
