没有NFC提供什么样的带宽？ [英] What Kind of Bandwidth does NFC Provide?

问题描述

我在寻找开始进入Android和NFC的一些项目。什么样的带宽，并提供NFC？这是假设我有连接到一个Arduino或类似的适当的NFC读/写，并与与之保持接触的Andr​​oid设备进行通信。很多人建议启动与NFC的通信，然后做通过蓝牙实际的数据传输，但我想知道带宽可供严格NFC通信，只是出于好奇。

I'm looking into starting some projects with Android and NFC. What kind of bandwidth does NFC provide? This is assuming I had a suitable NFC reader/writer attached to an Arduino or similar, and that was communicating with an Android device held in contact with it. Lots of people suggest to initiate the communication with NFC and then do the actual data transfer via Bluetooth, but I'm wondering the bandwidth available for strictly NFC communication, just out of curiosity.

推荐答案

空中接口所支持的​​数据速率是一回事。在卸下协议开销后，所看到的数据速率，等待EEPROM写操作和所有需要时间其他的东西，是一个完全不同的故事。

The supported data-rates of the air-interface are one thing. The data-rate that you see after removing protocol overhead, waiting for eeprom writes and all the other stuff that takes time is a whole different story.

长话短说，实际数据速率约为2.5千字节/秒。

Long story short, the practical data-rate when reading from a tag or doing peer-to-peer transfers peaks around 2.5 kilobyte/second.

和取决于具体的变量，或者它可以是对等技术的很多的比慢

And depending on specific tags or the peer technology it can be a lot slower than that.
