家园 【新品速递】你需要这样的东西吗？ -- WiFi探测器 爱飚车的朋友一般都要装备个“雷达探测器”，以保证不被测速的警察捉到。那么爱上网的朋友们是不是要装备这样一个WiFi探测器呢？它可以帮助你发现这里是否有wireless网络可以使用。欧美好多城市的公共场所都提供了这样的设施，比如机场，书店，咖啡厅等等。有了这个WiFi探测器，你就可以随时知道这个地方是不是可以上网，并且顺着它的指示，你可以找到信号最强的地方。怎么样，挺cool吧！
外链图片需谨慎，可能会被源头改Never again do you need to wait and power up your notebook only to realize that you do not have good WiFi access. No more dragging your notebook from location to location only to realize that you still cannot reach the 'net. Now, with a press of a button on the The WiFi detector, you will immediately find out if you're in the vicinty of a wireless network! The detector is an ultra-sensitive receiver that can detect WiFi signals up to 500 feet away in an outdoor environment, and up to 150 feet in an indoor environment. It can also detect both 802.11b and 802.11g standards for greater reliability. Its directional antenna even allows you to stand in one position and determine in which direction to move to ensure the greatest signal strength. Once you've found a signal, perhaps it could use a little boost? The Cantenna might be just the ticket...
家园 不见得 大多数的WiFi网会用WEP或其他方法来防止未经授权的使用。即使在机场或其他有公共HotSpot的地方，一般用户也只能访问有限的几个内部网站。所以，我的看法是，这样的东西并没有太大的用处。
