LOCAL ACTION INFORMATION SYSTEM
The work provides the results of the search for new methods and means of shortrange information communication systems. Comparison of different directions and technologies showed that the use of acoustic technologies in telephone and data exchange modes is not sufficiently implemented. A structure similar to cellular communication and algorithm of work is proposed. The choice of frequency resource is justified. The risk assessment of the implementation of technical solutions is presented. The novelty lies in the choice of interconnected technologies to achieve acceptable characteristics of information exchange. Hybrid systembuilding options are possible.
