Foreword This Technical Specification (TS) has been produced by ECMA on behalf of its members and those of the European Telecommunications
31、Standards Institute (ETSI). Brief History The present document specifies the interface and protocol for simple wireless communication between close coupled devices. These Near Field Communication (NFC) devices communicate with transfer rates of 106 kbps ,212 kbps and 424 kbps. The present document a
32、llows, but does not speciSl, applications in network products and consumer equipment. ETSI 8 ETSI TS 102 190 V1.l.l (2003-03) 1 Scope The present document defines communication modes for Near Field Communication Interface and Protocol (NFCIP-1) using inductive coupled devices operating at the centre
33、 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 a
34、lso for consumer equipment. The present document specifies, in particular, modulation schemes, codings, transfer speeds, and frame format of the RF interface, as well as initialization schemes and conditions required for data collision control during initialization. Furthermore, the present document
35、 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. 2 Conformance A system implementing the Active and
36、the Passive communication mode shall be in conformance with the present document if it meets all the mandatory requirements specified herein. 3 Re fe re nces The following standards contain provisions which, through reference in this text, constitute provisions of the present document. All standards
37、 are subject to revision, and parties to agreements based on the present document are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. In the case of references to ECMA Standards that are aligned with ISO/IEC International Standards, th
38、e number of the appropriate ISO/IEC International Standard is given in brackets after the ECMA reference. Referenced documents which are not found to be publicly available in the expected location might be found at http:/docbox.ctsi.ora/Wefe-enci. ITU-T Recommendation V.41 (1 988): “Code-independent
39、 error-control system“. 4 Defi n it ions For the purposes of the present document, the following terms and definitions apply: 4.1 Active communication mode Both the Initiator and the Target use their own RF field to enable the communication. This is the scheme of the Active communication mode. 4.2 A
40、SK modulation ASK stands for Amplitude Shift Keying. The amplitude of the carrier frequency is modulated according to the logic of the data to be transmitted. The degree of modulation is expressed by (a - b)/(a + b) x 100 %I, where a and b respectively represent the maximum and minimum amplitudes of
41、 the modulated signal waveform. 4.3 Binary Coded Decimal (BCD) A system for representing each of the decimal numbers O to 9 by a four-bit binary code. The bits, from left to right, are worth 8,4,2 and 1 respectively in decimal, so for example the number 6 in BCD is O1 10. ETSI 9 ETSI TS 102 190 V1.l
42、.l (2003-03) 4.4 Collision Transmission by two or more Targets or Initiators during the same time period, such that the Initiator or the Target is unable to distinguish from which Target the data originated. 4.5 Frame Sequence of data bits and optional error detection bits, with frame delimiters at
43、start and end. 4.6 Initiator Generates the RF field and starts the NFCIP-1 communication. 4.7 Load modulation Process of amplitude modulating a radio frequency field by varying the properties of a resonant circuit placed within the radio frequency field. 4.8 Isb first least significant bit fiist. In
44、dicates a serial data transmission system that sends lsb before all other bits. 4.9 LSB first Least Significant Byte first. Indicates a serial data transmission system that sends LSB before all other bytes. 4.1 O Manchester coding Method of bit coding whereby a logic level during a bit duration is r
45、epresented by a sequence of two defined physical states of a communication medium. The order of the physical states within the sequence defines the logical state. The coding system which divides into half at the changing point in the middle point of bit self-sustaining time, and makes the direction
46、of the changes correspond to two logic value. 4.1 1 Modulation index Defined as (a - b)/(a + b) where a and b are the peak and the minimum signal amplitude respectively with the value of the index possibly expressed as a percentage. When the maximum amplitude of the modulated signal waveform is set
47、to a and the minimum value is set to b, the degree of abnormal conditions is usually expressed as a percent. 4.12 msb first most significant bit. Indicates a serial data transmission system that sends the msb before all other bits. 4.1 3 MSB first Most Significant Byte. Indicates a serial data trans
48、mission system that sends the MSB before all other bytes. 4.14 NFCIP-1 device General term for either an Initiator or a Target communicating in the Active or the Passive communication mode. ETSI 10 ETSI TS 102 190 V1.l.l (2003-03) 4.15 NFC IDentifier (NFCIDn) NFCIDn is a randomly generated number us
49、ed by the RF Collision Avoidance and Single Device Detection sequence for both the Active and the Passive communication modes. 4.16 Passive communication mode The Initiator is generating the RF field and the Target responds to an Initiator command in a load modulation scheme. 4.17 RF Collision Avoidance (RFCA) Method to detect the presence of a RF field based on the carrier frequency and method to detect and resolve collisions on protocol level
