Abstract
A dual mode communication device utilizes a control channel to exploit diversity, history, and context in advance of establishing a broadband data exchange session on a broadband but shorter range wireless data channel, maximizing productive use of such a session. Appropriate diversity for the negotiated session further enhance data transfer, including path diversity, radio technology diversity (e.g., WiMax, Wi-Fi, ultra wideband, Bluetooth), antenna diversity (e.g., MIMO), modulation diversity (e.g., rate selection for 802.11, or symbol length selection to combat multi-path fading), and frequency diversity (e.g., 2.4 GHz versus 5 GHz). Historical information about channel characteristics optimize the selection of channel parameters with respect to the diversity choices. In addition, context information such as location and speed can be used to categorize the historical information that is collected to further optimize channel parameters.
