发明名称 Method for radio transmission of service data between a radio beacon and a mobile electronic information device with a radio connection evaluates data received to facilitate access to information and services for subscribers
摘要 Data for a service with little breakdown of data is transmitted via a unidirectional broadcasting connection by using JINI technology. Any subsequent transmission of data for one or more other services with a greater breakdown of data is carried out via a bi-directional connection. Any extra data transmission for the service with a greater breakdown of data is triggered by an appropriate situation to avoid multiple data transmissions from the same service.
