In recent years, wireless technology has developed rapidly. More and more users use wireless devices to establish wireless networks in their homes. By setting up wireless networks, they can use laptops and wireless network cards to access the internet in every corner of their homes. Many articles have introduced how to set up WEP encryption in wireless security to prevent other computers and illegal users from connecting to our wireless network. But is that true? Is the so-called WEP Security en

During the course of study, this parameter is often used. Later I worked mainly on audio/speech codec, but the concept of cepstrum was rarely used. I saw these words when I read a paper today, I think it is very practical. Let's review this signal feature. Time-cepstrum analysis is very effective when extracting the signal characteristics transmitted by the carrier. Cepstrum is widely used in the extraction of Speech Recognition feature parameters. This is because the essence of speech is the

encryption cracking. I. Difficulties in cracking the Wireless Router password: Before introducing the cracking operation, we should first understand the methods generally used to improve the security of our wireless network. ◆ Modify the SSID Number: Go to the wireless device management page and modify the default provider's SSID number, so that other users cannot connect to the wireless network by guessin

With the development of wireless networks, the use of wireless networks in our enterprises has become increasingly popular. How can we enhance network security performance in enterprises? How to Set. As the WEP and WPA encryption methods gradually break through, enterprise wireless networks become increasingly insecure, for intruders, as long as they can receive wireless communication packets from wireless networks, they will certainly be able to obtain the encryption key through brute-force cra

Wireless network technology is developing rapidly. In the face of growing network technology, how should we set it to be safer for enterprises? Here is a detailed introduction. As the WEP and WPA encryption methods gradually break through, enterprise wireless networks become increasingly insecure, for intruders, as long as they can receive wireless communication packets from wireless networks, they will certainly be able to obtain the encryption key through brute-force cracking, so that the ente

While Fourier transform (FT) can only process continuous signals, DFT is born in response to such a need. It is the representation of Fourier transformation in discrete fields. However, in general, the calculation of DFT is very large. Before the first high-speed Fo

Summary Starting from the analysis of GSM spectrum efficiency, this paper analyzes the loss of spectrum efficiency of voice service after the GSM network is upgraded to GPRS, and the new data service access ability, and finally takes into account the maximum access ability of the integrated service under GSM current spectrum from the mutual substitution between

must use Access Point. Ad-hoc is a special wireless network application mode. A group of computers connect to a wireless network card to connect to each other and share resources without Access Point. BSS in WLAN: a special Ad-hoc LAN application called Basic Service Set (BSS). A group of computers can have their own group with the same BSS name, this BSS name is called BSSID. ESS (Extended Service Set Extension Service Set) DS and multiple BSS allow 802.11 to form a wireless network of any siz

FFT (Fast Fourier transformation) is a classic algorithm used for digital signal processing. Many people who have studied DSP or chip design know this algorithm. However, have you ever wondered why there are so many FFT operations in digital signal processing? Some may say that in order to analyze the signal spectrum. The problem below is to analyze the daily needs of the spectrum, such as mobile phone call

This article gives you a detailed description of many methods for configuring wireless networks. Here we will give you a detailed description of some of the best methods and hope to help you. For network administrators, correct configuration of wireless networks is self-evident. Of course, there are many ways to correctly configure a network. The methods described here are not "Shortcuts", but they are at least the best. Here, we will list these three suggestions based on their importance: I. To

GetConfiguredNetworks ();For (int I = 0; I WifiManager. removeNetwork (configuredNetworks. get (I). networkId );}Return configuredNetworks;}It's easy to simply clear the historical configuration or set others as unavailable. 3. listener for successful wi-fi connection I do not like broadcast listening very much. There are many problems. I will directly judge the current Wi-Fi connection information. First, use wifiManager. getConnectionInfo () to obtain the current connectio

These days a new start to a HTC Desire HD mobile phone, the joy of playing, suddenly found a very good WiFi tools, can not help but share with you. Wifi Analyzer (#Android # Mobile version) Download link Https://market.android.com/details?id=com.farproc.wifi.analyzer What's the use of this thing? First, it can be used to search for nearby WiFi signals. (This feature is available in many apps, such as WiFi scanner or WiFi Manager, but this software can show strong signal strength, channel, e

problems. Similar to the Aruba Airwave monitoring tool, which solves most of the first-tier network problems, requires reporting to a higher level of engineer (second or third tier) if other problems arise. Dynamic WLAN testing using a distributed sensing platform Of course, the most important thing is to identify, detect, and then eliminate the failure before it affects the user experience. It is for this reason that businesses typically run automated Network Diagnostics tests-regularly conn

easily leaked, especially within the company. (2) WEP is not strong enough Although the common IEEE 802.11b and IEEE 802.11g standards use WEP encryption, it is also insecure. Because WEP generally uses a 40-bit (10 digits) key, the connection between the wireless network card and the Wireless AP encrypted by WEP is easily cracked. More serious security risks are the wireless network connection created through Windows XP by default and the WEP encryption disabled by the wireless router. (3) DoS

The features of the four wireless extended communication technologies are completely explained. First, let everyone understand the features of the wireless extended communication technology, and then fully introduce the features of the wireless extended communication technology. It does not matter. After reading this article, you will certainly have a lot of GAINS, I hope this article will teach you more things. The so-called spread-spectrum communica

The principle of PN Code synchronization in 1.CDMA system The transmitter and receiver adopt high accuracy and high stability clock frequency source to ensure the stability of frequency and phase. But in the practical application, there are many uncertain factors, such as the instability of sending and receiving clocks, uncertainty of launch time, transmission delay and interference, especially in mobile communication, these uncertainties are random, can not be compensated in advance and can on

configuration interface, in the "Wireless Network Basic settings" interface default configuration is as follows: ◆ Meaning of each parameter on the page: SSID: used to identify the service set identifier of a wireless device. A wireless router uses this parameter to identify itself, so that the wireless network card can distinguish different wireless routers to connect. This parameter is determined by the wireless router, not by the wireless network
