FIELD: information technologies.SUBSTANCE: system operates on the basis of a laser and a radio technologies and comprises serially connected sources of information, the first switchboard and the first collector, through which the input signal is sent to inputs of parallel connected communication lines attached to the collector: optical and high-speed radio frequency lines of millimetre range. The second collector and the second switchboard are attached to outputs of the specified communication lines, and through them a signal arrives to user servers. Additionally, between the first switchboard and the second collector via a synchroniser a highly reliable low-speed radio line of communication of centimetre range is connected, besides, to the input/output of control of the second collector there is a selector of data transfer speed connected, the input/output of which is attached to the input/output of the specified synchroniser.EFFECT: higher resulting speed of multimedia information transfer, achievement of high operator reliability and provision of high throughput capacity and reliability of communication lines without considerable increase of information transfer cost.1 dwg |
