Whe you have wifi enabled cell phone, you may find many wifi hotspot nearby, but most of them are encrypted, so you need to hack a wep key or a hack a wpa key.
This tool set has a number of foreign hackers to collect a variety of tools, you could use its wireless WIFI wireless network in the region do whatever they want. Wifi hack AIO 2009 includes Windows and Linux operating platforms, and some extra tools.
WIFI, full name of Wireless Fidelity, also known as the 802.11b standard, its greatest advantage is that a higher transmission speed can reach 11Mbps, while its effective range is also very long, but also a variety of 802.11DSSS with existing devices.
WIFI is AP (Access Point) and wireless LAN composed of wireless network. AP commonly referred to as the network bridge or access point, which is used as a traditional wired local area networks and wireless local area network as a bridge between, so that any one can be equipped with a wireless PC card to share the wired LAN through the AP network or wide area network resources, and its working principle is equivalent to a built-in wireless transmitter of the HUB, or routing, and wireless network card is responsible for receiving signals from the AP fired CLIENT premise equipment.
The main advantage of WiFi does not require wiring, can be exempted from wiring constraints, so it is suitable for the needs of mobile users, and has broad market prospects. Currently, it has been from the traditional health care, inventory control and management services and other special industries to more sectors open up to, and even begun to enter the family, as well as educational institutions and other fields.Health and Safety.
IEEE802.11 required transmit power can not exceed 100 mW, the actual transmission power of about 60 ~ 70 mW, which is what kind of concept? Phone transmission power of about 200 milliwatts to 1 watt, the hand-held walkie-talkie up to 5 watts, and wireless networks such as mobile phone usage is not a direct contact with the human body should be absolutely safe.
General set up a wireless network is the basic equipment for a wireless network card and the AP, so can use the wireless mode, with the existing cable infrastructure to share network resources, set up cost and complexity of procedures, far lower than that of traditional wired networks. If only a few of the peer computers, but also not AP, only need a computer with a wireless card for each. AP for the AccessPoint short, generally translated as "wireless access point", or "bridge." It is mainly in the media access control layer MAC play radio stations and wired local area network bridge. With the AP, just like a regular wired network Hub general, the wireless station can be quickly and easily with the network. Especially for the use of broadband, WiFi even more advantages, cable broadband network (ADSL, residential LAN, etc.) the home after connecting to an AP, then the computer can be installed in a wireless card. AP ordinary families have an adequate, or even the user's ne ighborhood are authorized, there is no need to increase the port, can also be a way to share Internet access.
Do not look at the working distance wireless WIFI is not, in the case of a complete network construction, 802.11b actual working distance can reach 100 meters or more, and when you solve the high-speed mobile data, error correction, error problems, WIFI equipment and equipment, equipment and base stations, switching and security authentication between the have been a very good solution.
