I believe many Internet users are no longer familiar with the 3G term. In the face of the arrival of 3G, many netizens cheered for the new "Broadband" era, because after a long wait, netizens can finally get rid of the limitations of wired networks, experience wireless Internet access. More importantly, in the 3G era, Internet users no longer need to suffer from

It is reported that, according to the operating data released by the three major domestic operators in July, as of the end of 0.159 billion, the number of 3G users in China reached. At the same time, the growth of 3G users slowed down significantly. The net increase of 3G users by the three major operators in April was no more than 3 million. Both China Telecom

Yesterday, Le Video network announced has been approved by the SARFT, allowed to carry out mobile phone video business in the future. In fact, a group of websites, including the red-headed, have already obtained the SARFT's. The use of mobile phone platform to provide audio-visual programs, seems to be the video web site industry from the bottleneck to break through the new opportunities. However, the industry said that video site 3G dream in the term

"After the issuance of a 3G license, more communication will be promoted between the operator and the agency channel, and the channel's right to speak will be enhanced. It will also bring more opportunities to the agency channel ." On the day of the announcement of the issuance of the 3G license, Suning chairman Zhang Jindong said in an interview with Daily Economic News reporter. He admitted

With the development of mobile communication in China, the construction of the third generation mobile communication network has become the focus of major telecom operators. The third generation mobile communication technology test network of the Ministry of Information industry is led by the Ministry of Information industry to participate in the formation of the major telecommunications operators, the test network in the 2GHz band, respectively, WCDMA R99, TD-SCDMA, CDMA2000 1X Three kinds of

supervision and inspection center was inspected in April 29, the test items include the uplink rate comparison test, the noise coefficient of the superconducting Link System (BL), the BL band inner benefit and the BL out-band suppression test. The test report shows that the uplink speed of the TD-LTE system and superconducting TD-LTE system is improved by 37.4% and the maximum speed is 59.7% without interference. Under the conditions of interference, the network speed is increased by a minimum

Add the-fprofile-arcs-ftest-coverage parameter to the GCC compilation to generate a binary program, and execute the test case to generate code coverage information.1. How to Use gcov The-fprofile-arcs-ftest-coverage option is adde

Do I still need WAP in the 3G era?(Article: Hero Wang) Recently, when chatting with friends, I often mention a topic. Do I still need WAP in the 3G era? This is a good topic. Most of the people who ask this question are WAP practitioners. What they are most worried about is that in the 3G era, when users use 3G to acc

Before the software test class, see the teacher demonstrated a statistical C language test coverage of the tool, then want to know. NET has the same tool. It happened yesterday to find clover.net, which can help you analyze the code that has been tested. Here are some of the information about coverage analysis in our software testing lesson: Coverage analysis i

PS: no navigation function is available after upgrade to baseband 06.15, Unless your iPhone baseband is already 05.14 or 05.15 and you need to upgrade it to 06.15, we recommend that you do not upgrade it for the time being. PreviousIt cannot be downgraded back to the old baseband. Now the new version can be downgraded back to the baseband, but some machines still cannot be downgraded, depending on your luck. My personal character is guaranteed, and the baseband is downgraded once. By the w

The Most mature 3G network system is the WCDMA developed by the 3GPP project team. WCDMA network structure, can refer to Figure 12.1, which has several characteristics. 1. Reverse-compatible Gsm/grps network. The base station subsystem (BSS) of the original GSM network remains unchanged and can be interconnected with the transformed core network via the original a protocol stack and the GB protocol stack. 2. The core network maintains the netw

With the development of the routing industry, IPv6 routers are also widely used. So I have studied the practical application of IPv6 routers in the 3G mobile communication system. Here I will share with you, I hope it will be useful to you. Due to the rapid development of Internet and Internet applications in recent years, the number of people using networks and computers that are new to the Internet has rapidly increased. Currently, the 32-bit IPv4 a

Whether it is unit testing, API testing, or functional testing, the code of the product is eventually called. How to evaluate the efficiency of these tests and whether all or most of the code of the product is covered? At this time, code coverage is a valuable reference indicator.Generally, code coverage is used in the following aspects: Find out the places where the code is not tested; Add new test code

Code coverage is an important indicator that reflects the coverage of test cases to tested software. It is also an important indicator to measure the testing progress. It is also an important indicator for Testing. Testing is often not as exciting as development. One of the important reasons is that testing is difficult to quantify, code coverage is an important

First, the experience of video call, after the temptation of high-speed Internet. Today, the three 3G technical standards will start completely. However, the parties on the 3G high-speed publicity despite the overwhelming, there is said that the test speed has reached 15Mbps, there are claims that the speed of 7.2Mbps, but the average consumer or "Mongolia check", 3G
