This glo

22、ssary of terms enables the communication between non-specialist users and specialists in radio communications through a common understanding of basic and advanced concepts. 2 Classification of entries The numbering system employed within ISO/IEC 19762 is in the format nn.nn.nnn, in which the first t

23、wo numbers (nn.nn.nnn) represent the “Top Level” reflecting whether the term is related to 01 = common to allAIDC techniques, 02 = common to all optically readable media, 03 = linear bar code symbols, 04 = two-dimensional symbols, 05 = radio frequency identification, 06 = general terms relating to r

24、adio, 07 = real time locating systems, and 08 = MIIM. The second two numbers (nn.nn.nnn) represent the “Mid Level” reflecting whether the term is relatedto 01 = basic concepts/data, 02 = technical features, 03 symbology, 04= hardware, and 05 = applications. The third two or three numbers (nn.nn.nnn)

25、 represent the “Fine” reflecting a sequence of terms.The numbering in this part of ISO/IEC 19762 employs“Top Level” numbers (nn.nn.nnn) of 06. 3 Terms and definitions 06.01.01 radio frequency frequency of a periodic radio wave or of the corresponding periodical electrical oscillation NOTE This term
