Numbering system formats GB/T 29261 used as nn.nn.nnn, where the first two numbers (nn.nn.nnn) on behalf of the "top level", and its value on behalf of the 01 common to all automated identification and data capture techniques, common to all 02 representative of an optically readable media, on behalf of a 03-dimensional bar code, 04 on behalf of two-dimensional bar code, 05 representatives of radio frequency identification, radio 06 for general terms, 07 representatives of real-time location system 08 on behalf of moving objects Product identification management. Two middle numbers (nn.nn.nnn) means "middle", its value is 01 or on behalf of the basic concepts of data, 02 representatives of technology Property, on behalf of 03 symbols, 04 on behalf of hardware, 05 on behalf of the application. Two or three numbers (nn.nn.nnn) later expressed a term sequence Column "segment." this section GB/T 29261 using numerals (nn.nn.nnn) of the "top" number is 06

3 Terms and Definitions

06.01.01

Radio frequency RF radiofrequency Periodic electrical periodic radio waves or frequencies corresponding to the frequency of oscillation.

Note. The terms and abbreviations may be modified to produce or collect electrical device radiation waves.

[GB/T 2900.54-2002, the definition 713-06-02] 06.01.02 RF data communication radiofrequencydatacommunication A remote device through a wireless link to communicate with the host system.

Note 1. The handheld readers do not need to establish a fixed cable line will be able to collect information to send back to the control program;

Note 2. a universal application of RF data communication is in the truck.

06.01.03

Field electromagneticfield State of matter characterized medium or vacuum electric, magnetic field, is defined by the following four vector set.

--- The E field intensity (vector);

-> D --- electric flux density (vector);

-> H --- magnetic field intensity (vector);

--- The magnetic flux density B (vector).

Note 1. The electromagnetic fields obey Maxwell's equations.

Note 2. The concept of quantum of electromagnetic phenomena can be ignored without meter, the electromagnetic field definition is valid.
