Normally, when 3G and WiFi are on, Android uses Wi-Fi by default, but it is not possible to have WiFi everywhere in the real world, so the phone will often automatically switch networks.Sometimes, when the phone starts using WiFi, it will automatically switch from WiFi to 3G network 10-30 minutes after it enters standby.If you write a network program, the effect of automatic network switching on the program

want to break through a pool of stagnant water, you can try the 3G principle. Dare to think (GAn), dare to do (GAn), dare (GAn ). 1. Dare to think Dare to break through some conventions, dare to think about it. It's not how it was done, but who did it. Instead, consider how things should be done, how to do things best, and how you want to do things. Rather than sticking to existing rules and forms. Jump out and think about what you want to do and how

The letters displayed on the mobile phone network represent the network in use. In addition to the commonly mentioned 3G network, there are also 2G networks, 2.5G networks, 2.75g networks, and 3.5G networks. 2G is a common GSM network, and 2.5G is added with GPRS or CDMA (earlier version) on the basis of GSM ), 2.75g is an edge network added on the basis of the GSM network (somewhat similar to GPRS but with faster speed).

Today, I got the 3G test experience card from China Telecom. I went home and tried it. On an FTP server that is frequently downloaded, the speed is almost the same as that of China Telecom ADSL. 175 KB/s is caused by the server speed limit, I downloaded a small file with thunder, and the speed can be above kb. Qq transit upload is stable at 80 KB/s or above: 3G wireless charges have basically co

This is com4.Choose Start> qpst configuration.Select the ports tab, click Add new port in the lower-right corner, enter com4 in the port and port lable fields on the interface (enter com4 if the value is displayed on your computer), and click OK.Now port should be displayedActive phone is displayedIf it cannot be identified, re-dial the phone or try to delete the unused

In the past, when using the 3G module of Huawei em730, they provided a dialing software. In the beginning, the dial-up software must be used before the dial-up is successful, and the dial-up connection in the wince control panel cannot work normally. Later, I tried to use the dial-up connection provided by wince to make the dial-up work normally, mainly by modifying some configurations in the registry. Recently, we have to use the surfing of China Tel

ModelSim code coverage function code coverage, which can report statement, branch, condition, expression, and toggle) and FSM (finite state machine.1. Compile option ): In The Modelsim workspace, select the file for viewing code coverage, and right-click compile-> compile properties, as shown in. Select the "coverage

Day-feed coverage, as the name implies is the use of AP, feeder, plus ceiling antenna to build wireless network. thereby reducing the use of APS to reduce the interference of the same frequency.Working principle:Day-feed coverage using APS are high-power industrial wireless APs, power is the general home wireless router 7-8 times, is the general ceiling-type AP 5-6 times, high-power is to ensure the basic

Emma is an open-source tool used to detect and report Java code coverage. It is not only suitable for small projects, but also for large enterprise projects. Emma has many advantages. First, you can get it for free and use it for your own project development. It supports many levels of coverage metrics: packages, classes, methods, statement blocks (basic blocks) and rows. In particular, it can determine wh

Coverage Tool)Java:EMMA: advantages: 1. Open-source software; 2. Support for ant tasks; Emma is open-source and has little impact on application execution speed.Disadvantage: The parameter setting of 1 ant task is weak, and the coverage parameter needs to append the configuration file.Emma is a free and open-source Java code coverage testing tool. It is written i

The previous article describes how to let Surefire,failsafe and Jacoco maven plugin How to combine configuration, this article specifically explains how to use the Powermock agent to solve coverage incompatibility problems.First add Powermock agent maven dependency in POM Note:it ' s recommended that's put powermock-module-junit4-rule-agent before JUnit in the classpath. (Remember to put this dependency before JUnit). Next, modify the previous test

(I am participating in the 2015 blog Star Selection, invite you to vote, thank you: HTTP://VOTE.BLOG.CSDN.NET/BLOGSTAR2015/CANDIDATE?USERNAME=ZHOUZXI)Recently, I accidentally found the GCOVR tool on the Web because I wanted to show code coverage for unit tests for a project. After use, think this tool is quite good, so write this article, for the relevant developers to reference.In short, GCOVR is a tool that displays code
