ECMA-340标准介绍

近距离通信(NFC)是最近几年兴起的一门新的自动识别和无线通信技术,它利用无线射频方式在发起者和应答者之间进行非接触双向通信,以达到目标识别和数据交换的目的.文中介绍了近距离通信的协议标准ECMA-340及其主要内容、特点、防冲突机制和发展前景,对标准中技术做了分析,并结合未来的发展趋势指出了现有标准中有待改进的方面.

Introduction to ECMA-340 Standard

Near Fileld Communication (NFC) is a new automatic identification technique and wireless communica- tion technique being developed in recent years. It finishes the function of non-contact, full-duplex com- munication in the wireless radio frequency manner between a initiator and a target to exchange data and identify a target .This paper introduces NFC based on ECMA-340 standard, including its background, concept, attribute and its technological details. It also narrates in detail the anti-collision algorithms and analyzes its performance. Several key techniques used in ECMA-340 are discussed in this paper too.
