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.
Ozmo has written a software patch that allows a laptop's Wi‑Fi to communicate in tiny time slices, using some to talk with local peripheral devices and the rest to maintain its connection to the router. Company cofounder Roel Peeters says the strategy of letting the laptop talk directly to a peripheral keeps latency to about 10 milliseconds, the same as Bluetooth's.
Second, Wi-Fi is notorious for the way it sucks up power—typically cutting a laptop's battery time in half, making Wi‑Fi unsuitable for a small-battery-powered headset or keyboard. Ozmo's chip set not only draws far less power than off-the-shelf chips but also outperforms Bluetooth, because it goes to sleep when not actively engaged in sending or receiving data. Based on in‑house testing, Peeters estimates the power consumption to be one-third to one-fourth that of Bluetooth's. The tradeoff is the peripheral's data rate—9 megabits per second versus Wi-Fi's standard 54 Mb/s. Still, that's three times as fast as Bluetooth's top speed.

“ 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.
