gsm sniffing

There is no doubt that GSM is the technology that enables mobile phones to enter the global consumer market. The Nordic countries, Hong Kong and Australia lead the penetration of mobile communications, and GSM has the potential to continue to achieve global success on the world market. New wireless data technologies, such as high-speed circuit-switched data (HSCSD) and general Packet Radio Services (GPRS),

1 Current 3G situation and important issues that people focus on People's focus on 3G has gone through two different stages. 2001-2002, people's energy is mainly focused on mastering 3G basic technology, through indoor testing and field debugging and other means of technical validation; 2003-2004, while continuing to verify the 3G important technology, on the basis of continuous research on 3G experience at home and abroad, 3G requirements and understanding are covered to 3G system-wide require

from defender to defender. The so-called "attack" here is not a direct intrusion into the hacker's computer. I believe this "technical activity" is not suitable for everyone. This is just to start with the vulnerabilities in almost all the software, so as to give hackers a lesson. So what is this vulnerability? From the previous analysis of "ah la QQ grand theft", we can see that the configuration section contains the email account and password for receiving QQ number information emails, while

At the beginning of the 21st century, China's mobile phones were once brilliant. brands such as TCL, KONKA, shouxin, Dongxin, waveguide, and Southern Gaoke once became proud of China, even in the face of TI's millions of USD in license fees, it also failed to block the enthusiasm of China's mobile phone investment in R D. Unfortunately, with the rise of lianfa's turnkey business model, shanzhai mobile phones have pushed China's mobile phone brands to a slump again. After years of elimination, s

Welcome to the IT technology community forum, and interact with 2 million technical staff. Table 1 Comparison of WCDMA and GSM signal distribution from the relationship between RSCP and EcIo, when RSCP approaches-100dBm, the corresponding EcIo is-7 ~ -9 dB, and EcIo will reach below-14dB when RSCP is below-110dBm; when the pilot signal is clean, RSCP is-105dB Welcome to the IT Community Forum and interact with 2 million technical staff> Table 1 Compar

From http://blog.sina.com.cn/s/blog_4d0d56900100bs3y.html Community breathing: The CDMA network is completely different from the GSM network. Because the channels and users are no longer separated, there is no difference between traditional coverage and capacity. The larger the business volume of a residential area, the smaller the residential area. In CDMA networks, increasing business volume means increasing interference. The effect of dynamic chan

In our context, security cannot be built on the basis of a solid security.WLANs are designed with specific insecurity that can be easily exploited, for example, through packet injection an

This yum source is hard to find on the Internet and I do not want to download a redhat iso image from the server, build a yum source to provide download, which is not very secure. So?Try to make the redhat yum source use the centos yum source for installation. It is not possible by default. Do not try it. Be careful when your system installation package is incompatible 1. Delete the original yum source of redhat. Default # Rpm-aq | grep yum | xargs rpm

technology. 2. General grouping wireless service GPRSGPRS is a Packet Exchange Protocol defined according to the GSM standard. It establishes a "always-Online" connection between the mobile terminal and the network, and the network capacity is occupied only when the network capacity is actually transmitted. It is an efficient way to transmit data based on group exchange. It adds the group exchange function in the

The most reliable way to send is, of course, with the hands of the mobile phone, if set a status report, more accurate to know whether the other party received this message. Mobile ph
