Title:
METHOD FOR THE WIRELESS AND REMOTE TRANSMISSION AND RECEPTION OF CODED INFORMATION, VARIANTS AND PORTABLE DEVICE FOR REALISING THIS METHOD
Document Type and Number:
WIPO Patent Application WO/2000/028680
Kind Code:
A1
Abstract:
The present invention relates to a computer device which is aligned with a radio transceiver and comprises a memory into which data consisting of a formatted information block is introduced, said block being assigned a personal code after a conversion process. The code is transmitted in the form of pulse radio signals through a broadcasting system in order to be received by other devices operating in the action area of the first device. Upon reception of the radio signals, the codes thus received are compared with the personal code and, if they coincide, the data thus obtained and corresponding to this code are decoded and extracted. When establishing correlations, a pulse radio signal is transmitted according to the code involved in the coincidence in order to indicate said coincidence, and a response pulse radio signal concerning the personal code is received for their mutual identification. After receiving the pulse radio signals concerning the personal code and confirming the establishment of a direct contact, the subscribers' devices are switched into a direct communication mode so that said subscribers can communicate together. When the codes received do not coincide with the personal code, said codes are introduced into the memory and are spread into the broadcasting system during a period free from any pulse radio signal comprising a code corresponding to the personal code.
