Why does a laptop need both Wi-Fi and Bluetooth? A Bluetooth chip creates a personal area network, allowing peripherals like keyboards, mice, and headsets to communicate wirelessly with a laptop or mobile phone. But why can't that network be a subset of the Wi-Fi local area network? Why can't Wi-Fi manage all our wireless communications?
Two big problems have prevented convergence, but they've both been solved by Ozmo Devices, a Palo Alto, Calif., start-up—and at a data rate that's much faster than Bluetooth's.
First, while a computer's Wi‑Fi can communicate with other Wi-Fi devices, it cannot do so at the same time it's talking with a router. So for a Wi‑Fi–enabled keyboard to interact with a laptop computer without taking it off-line, the keyboard would need to contact the router, which would then route the data back to the laptop. But this is so inefficient that users would notice delays in keystrokes showing up onscreen.

“ Fi的无线需要对B ; uetooth ”
为什么笔记本电脑既需要Wi - Fi和蓝牙？蓝牙芯片创建一个个人区域网络，使外设像键盘，鼠标，和耳机，以无线通讯与笔记本电脑或移动电话。但是，为什么不能成为该网络的一个子集的Wi - Fi局域网？为什么不能Wi - Fi的管理我们所有的无线通信？
两大问题阻碍收敛，但他们都已经得到解决的Ozmo器件，一个位于加州Palo Alto ，启动和在数据传输速率是速度远远超过蓝牙的。
首先，虽然电脑的Wi - Fi可以与其他Wi - Fi设备，它不能这样做的同时，在谈论同一个路由器。因此，为Wi - Fi功能的键盘与笔记本电脑没有考虑它离线，键盘将需要联络的路由器，然后路线的数据备份的笔记本电脑。但是，这是效率低下，用户将通知延误击键显示在屏幕上。
Ozmo写了软件补丁，使笔记本电脑的Wi - Fi通讯的小时间片，利用一些人跟当地的外围设备和其他保持其连接到路由器。公司创始人胡彼得斯说，这一战略让笔记本电脑的直接对话周边不断潜伏期约10毫秒，相同的蓝牙。
为什么笔记本电脑同时需要Wi-Fi和蓝牙呢？一块蓝牙芯片生成独立的区域网络，同时允许诸如键盘、麦克风以及耳机之类的外围设备与笔记本电脑或手机进行无线通讯。但为何这个网络不能由Wi-Fi来兼管呢？为何Wi-Fi不能集成管理所有的无线通信呢？
两个问题影响了集成，但是如果启动Ozmo设备，这两个问题都解决了，而且通信速度远比蓝牙要快。
首先，当电脑的WiFi与其它WiFi设备通信时，它就不能同时与路由器交换数据。因此，如果在WiFi键盘不挂断的情况下与电脑交换数据，由于键盘需要连接路由器，只能把数据先收回电脑。这样用户会感觉到显示比按键慢了几拍，运行效率很低。
