昨天,应该说昨天吧!
昨天上午买了一个usb的蓝牙信号接收器,本来想买一个卫星信号接收器(主要收集有线电视信号),结果没有货,估计当地的政策管得非常严,没有人敢卖那玩意儿。把现在买的usb接收器和原来我买的一个usb接收器做了对比,开始我以为是同一型号,结果发现不是。分别驱动后,安装,把其中一个以pppoE方式连接的机器当作服务器,拨号,作成局域网。这样就做成了一个小型局域网,反拨,这样无论哪方能上网,都能互相连上internet,好象很方便,嘻嘻。
但是这样组建的局域网,发现文件Copy速度很慢,速度为10kbps,还不如直接连接文件,速度能达80-90kbps。
蓝牙除了无线优点(分布范围在10m左右都可以)、组网和连网的方便外,还有比较安全的数据传输手段,可以进行点对点的加密传输,适合各种环境的作业。
蓝牙还是有缺点的,由于是无线,蓝牙发射的信号弱且很容易受到干扰,故此,蓝牙适合小部分人群使用。
我已经有了二颗蓝牙了,你有几颗呢? :)
