Documents about NFC RF transmission standard

hello

i would like to know what is NFC rf transmision standard. Does any special document state it or it is simply compliant with existing RFID ISO standards(14443 or 15693)

if yes, can you post any docs about nfc ?

regards

There is a specific document http://www.ecma-international.org/pu...T/Ecma-340.pdf
And the test methodhttp://www.ecma-international.org/pu...T/Ecma-356.pdf

isn't it described by any ISO standard ?

what about field strenght and modulation type ? is it inherited from both 14443 and 15693 or is defined in its own way ?

regards

As you can see from ECMA-340, NFC has been almost copied from ISO 14443, particularly the pysical layer, the main supplement is regarding active poin-to-point communication.

do you have any behavioral models of RF interface working on 13.56MHz ?

or can you recommend a useful literature ?
