Abstract
Delivery of non-standard frame field information can be accomplished by publicly broadcasting the non-standard frame field information in one or more broadcast frames within an open wireless computing network. The broadcast can be received by a client wireless device when the client wireless device has not established a connection to the wireless network. The client can store the received information. A system for delivery of non-standard frame field information can comprise a special-purpose access point configured to deliver the information by broadcasting the information in a plurality of broadcast frames. The system can also comprise a client wireless device that receives the broadcast and aggregates the received information when the client is not connected to a wireless network.
