In fact, the content of the basic knowledge of wireless is still quite many, but because this book focuses on the use of BT4 own tools to explain, if you carefully talk about these peripheral knowledge, this is like to tell the DNS tool also to the DNS server type, working principle and configuration to tell the same, haha, It is estimated that the thickness of the whole book needs to be doubled one or twice times. Well, the basic knowledge of wireless network advice you can refer to my previous

WPA has the ability to run the "pre-shared key mode", WPA deployment in the SOHO environment does not require authentication servers. Similar to WEP, a client's pre-shared key (often referred to as a "pass word") must match the pre-shared key stored in the Access Point. the Access Point uses the pass word for authentication, if the traffic characters match, the client is allowed to access the access point. Encryption and cracking steps of Wireless Access Point WPA-

, because the operation process is difficult, the general user implementation is not very realistic. So a simplified version of WPA ――WPA-PSK (preshared key) is used in the home network. Third, please set the exact line before, at the same time ensure that there is a network cable connected to the computer and no lines by the LAN port, in order to facilitate the login router configuration at any time. (i), settings and instructions on the router Op

We have introduced three encryption methods: WEP encryption for conventional wireless security measures, restriction of MAC addresses for wireless NICs to make the network more secure, and prohibition of wireless SSID broadcast to protect network security, the WPA-PSK wireless encryption introduced in this article is a special encryption method, because some NICs do not support this encryption method. 1. Configure WPA-

amplitude 1V, frequency 10KhzMultiplier with default settingsSimulation Waveform:0Simulation Results Analysis:The signal source generates a square wave signal of positive and negative 1V, and the frequency is 2.5KHz. The AC signal source is 10KHz, so a square wave period will contain 4 sine waves. When the square amplitude value is positive 1V, and the sine signal is multiplied, the result is the sine signal itself. When the square amplitude value is negative 1 V, and the sine signal is multipl

The English quadraturephaseshiftkeying abbreviation, stands for orthogonal phase shift keying, is a digital modulation method. The four-phase Phase Shift Keying Signal is short for "PSK ". It can be divided into absolute phase shifting and relative phase shifting. The following figure shows the principle of the following: The following digital demodulation methods are available: analog-to-digital conversion, extraction or interpolation, matching fil
