Abstract (en)
[origin: WO9411967A1] A system for the distribution of information, particularly at a tourist site, has a central computer network (1) with a main processor (DP) holding source data networked with node computers (NN). The computers of the network (1) are connected to a telephone exchange (2) which in turn connects to radio exchanges (3), sending to radio base stations (4) which relay and receive transmitted radio signals to/from portable telephone handsets (5). Data of the data source are indexed so that item-specific requests can be sent from the handsets, either manually or by automatic trigger, to initiate the sending of appropriate information items addressed to the appropriate handset (5) from the source data. One or more levels of data catching can be provided between the source data and the telephone exchange (2), to enhance simultaneous service of numerous handsets (5).
