ISO IEC 18092:2013 pdf free.Information technology – Telecommunications and information exchange between systems – Near Field Communication
ISO IEC 18092 defines communication modes for Near Field Communication Interface and Protocol (NFCIP-1) using inductive coupled devices operating at the centre frequency of 13,56 MHz for interconnection of computer peripherals. It also defines both the Active and the Passive communication modes of Near Field Communication Interface and Protocol (NFCIP-1) to realize a communication network using Near Field Communication devices for networked products and also for consumer equipment. ISO IEC 18092 specifies, in particular, modulation schemes, codings, transfer speeds, and frame format of the RF interface, as well as initialisation schemes and conditions required for data collision control during initialisation. Furthermore, this International Standard defines a transport protocol including protocol activation and data exchange methods.
Information interchange between systems also requires, at a minimum, agreement between the interchange parties upon the interchange codes and the data structure.
In the Passive communication mode, the Initiator generates the RF field and starts the transaction. The Target responds to an Initiator command in the Passive communication mode by modulating the Initiators’ RF field which is referred to as load modulation.
This International Standard specifies requirements for modulation, bit rates and bit coding. In addition it specifies requirements for the start of communication, the end of communication, the bit and byte representation, the framing and error detection， the single device detection， the protocol and parameter selection and the data exchange and de-selection of Near Field Communication Interface and Protocol (NFCIP-1) devices.
Transactions start with device initialisation and end with device de- selection. Initiators and Targets exchange commands, responses and data in alternating or half duplex communication.
The Target shall be capable of communication to the Initiator via an inductive coupling area by using load modulation applied at fc of the Initiator’s RF field with the PICC load modulation amplitude value specified in 8.2.2 of ISO/IEC 14443-2.The Initiator shall be able to receive a signal with load modulation amplitude as specified for the PCD reception in ISO/IEC 14443-2, 8.2.2.
NOTE The minimum load modulation amplitude value for the Target and Initiator has been modified from ISO/IEC 18092:2004.ISO IEC 18092 pdf free download.
