ISO/IEC 18000-4:2004 Information technology - Radio frequency identification for item management - Part 4: Parameters for air interface communications at 2,45 GHz
This part of ISO/IEC 18000 defines the air interface for radio frequency identification (RFID) devices operating
in the 2,45 GHz Industrial, Scientific, and Medical (ISM) band used in item management applications. The
purpose of this part of ISO/IEC 18000 is to provide a common technical specification for RFID devices that
may be used by ISO committees developing RFID application standards. This part of ISO/IEC 18000 is
intended to allow for compatibility and to encourage inter-operability of products for the growing RFID market
in the international marketplace. This part of ISO/IEC 18000 defines the forward and return link parameters for
technical attributes including, but not limited to, operating frequency, operating channel accuracy, occupied
channel bandwidth, maximum EIRP, spurious emissions, modulation, duty cycle, data coding, bit rate, bit rate
accuracy, bit transmission order, and where appropriate operating channels, frequency hop rate, hop
sequence, spreading sequence, and chip rate. This part of ISO/IEC 18000 further defines the communications
protocol used in the air interface.
This part of ISO/IEC 18000 contains two modes. The first is a passive tag operating as an interrogator talks
first while the second in a battery assisted tag operating as a tag talks first. The detailed technical differences
between the modes are shown in the parameter tables.
