问题 (The Question)
SuperUser reader jt0dd wants to know if Bluetooth is faster than Wi-Fi:
超级用户阅读器jt0dd想知道蓝牙是否比Wi-Fi快：
I notice that on my iPhone, when I use my personal hot-spot to distribute Wi-Fi and I have Bluetooth enabled, the phone will make a Bluetooth connection to my laptop instead of a Wi-Fi connection.
我注意到在iPhone上，当我使用个人热点分发Wi-Fi并启用了蓝牙功能时，手机将通过蓝牙连接到笔记本电脑，而不是Wi-Fi连接。
So I am wondering…is Bluetooth faster than Wi-Fi?
所以我想知道……蓝牙比Wi-Fi快吗？
Which one is faster?
哪一个更快？
答案 (The Answer)
SuperUser contributor Mokubai has the answer for us:
超级用户贡献者Mokubai为我们提供了答案：
The Bluetooth standard’s maximum data rate is, at best, 3 Mbps or about 2.1 after protocol overheads take their cut.
降低协议开销后， 蓝牙标准的最大数据速率最多为3 Mbps或约2.1。
Wi-Fi on the other hand, maxes out anywhere from 54 to 1300+ Mbps depending on whether you have “g”, “n”, or “ac” Wi-Fi plus any enhancements in the adaptors and router support.
另一方面，Wi-Fi的最大范围为54到1300+ Mbps，具体取决于您是否具有“ g”，“ n”或“ ac” Wi-Fi，以及适配器和路由器支持的任何增强。
So no, Bluetooth is not faster than Wi-Fi. Not even vaguely close.
所以不，蓝牙并不比Wi-Fi快。 甚至没有隐约地关闭。
Bluetooth version 3 and version 4 have higher data rates, but the actual data transfer in those implementations happens over Wi-Fi; Bluetooth is only used to set up and negotiate the connection.
蓝牙版本3和版本4具有更高的数据速率，但是这些实现中的实际数据传输是通过Wi-Fi进行的； 蓝牙仅用于建立和协商连接。
