  • Patent number: 7751543
    Abstract: Systems and methods for button-independent dispatch communications are provided. A dispatch station monitors a microphone input to determine whether it provides voice information. When the input provides voice information, the dispatch station then determines whether the floor of the dispatch communication is open. When the floor is open, the dispatch station seizes the floor and transmits the voice information. When the floor is not open, the dispatch station can store the voice information and transmit it once the dispatch station is able to seize the floor.

  • Patent number: 7751810
    Abstract: A system and method of transmitting multimedia data related to an event to the wireless communication units of the event attendees. The multimedia data may be broadcasted on a plurality of channels. For example, multimedia data generated from different cameras across the event venue may be placed on multiple channels. Attendees using mobile communication units may tune to any channel in order to view the event performances from the perspective of the selected camera. Also disclosed is a method of provisioning a mobile communication unit for receiving wireless communication services at an event. In this regard, a user purchases or rents a mobile communication unit containing a unique identifier residing in a radio frequency identification (RFID) tag. The user also purchases for receiving wireless communication services for a particular event. A provisioning device at the event venue reads the identifier from the RFID tag to provision the mobile communication unit for receiving wireless communication services.

  • Patent number: 7729246
    Abstract: Systems and methods for communications between networks that support dispatch communication services are provided. A server is coupled to at least two networks that provide dispatch communications, one of which employs an inactivity timer.
