Abstract: Proposed a method of wireless data exchange amongst ad-hoc mobile devices of limited range within a communications network, the network comprising a plurality of mobile units including a source mobile unit and a destination mobile unit and a plurality of wireless communication links wirelessly connecting together, the said method comprising—a special communicative protocol supporting a plurality of tasks in connection with ad-hoc network abilities (CYRF protocol),—a special communicative protocol supporting a plurality of tasks on global communications (GLOBAL MESSAGING TRANSPORT),—a special entertainment—, e-mail—and organizer type features, based on wireless ad-hoc networks″abilities gained by said protocols.

Abstract: This invention relates to radio engineering, and in particular it concerns a method of establishing contact between users. The method consists in that, in a portable computerized device combined with a radio transceiver, data comprising an array of formed information, which is, upon conversion, assigned a personal code, is inputted into the memory. Then, this code is transmitted in the form of pulsed radio signals through the propagation medium for reception thereof by other devices operating within the range of the first device. Upon reception of pulsed code radio signals transmitted by other devices, the codes received are compared with the personal code, and when one of the codes received is found to coincide with the personal code, the received data corresponding to that code is decoded and outputted for visual or audio perception of the information array corresponding to that code.
