  • System and method for broadcasting application-specific information in wireless local area networks
    Patent number: 7505443
    Abstract: A system and method for a novel broadcasting scheme (NBS) in a wireless local area network are described, which can operate with or without a network connection. The system permits transmission of application-specific data through a specific field in a beacon frame, the Service Set Identity (SSID). By implementing a NBS Processor in an AP and a NBS Parser in stations, the AP can broadcast application-specific data while the stations can automatically act upon the receipt of the broadcast.
