Abstract: Methods, systems and devices for presenting marketing information to a customer based on proximity to marketing areas. A wireless identity transmitter associated with the customer may periodically transmit wireless broadcast messages that include obscured identifiers. A proximity broadcast receiver within a retail store, such as near a product display or aisle, may receive and relay the broadcast messages to a server which may process the included information. Based on proximity information and other conditions, the server may transmit marketing information relevant to the customer and a proximate marketing area, such as coupons and offers. In an embodiment, the server may store data based on broadcast messages that may indicate foot traffic and other information valuable to merchants. The server may also transmit messages based on stored permissions that indicate whether the customer desires to receive marketing information and whether the server is authorized to provide the customer's identity to merchants.

Abstract: Methods, systems and devices for providing relevant user information to devices within proximity of a user. A wireless identity transmitter associated with the user periodically broadcasts messages that include obscured identifiers. A proximate proximity broadcast receiver may receive and relay the broadcast messages to a central server which may process the included information. Based on categories related to the proximity broadcast receiver and the user, the central server may identify subsets of stored profile information about the user that are relevant to the proximity broadcast receiver. The central server may transmit relevant profile information to devices to assist in activities associated with the proximity broadcast receiver. In an embodiment, the central server may only transit relevant profile information that is authorized by the user via permissions associated with the profile.

Abstract: A system for transmitting a data stream, includes a transmitter for broadcasting a radio frequency communication signal comprising at least one superframe having at least a first data stream encoded therein, and overhead information carried in the superframe, the overhead information comprising a control channel, the control channel having control channel information for separating the at least one first data stream from any other data streams encoded in the at least one superframe. A system for receiving data includes a receiver configured to receive a radio frequency communication signal comprising at least one superframe having at least a first data stream encoded therein; and overhead information carried in the superframe, the overhead information comprising a control channel, the control channel having control channel information for separating the at least one first data stream from any other data streams encoded in the at least one superframe.
