season解答的关于在NS仿真中出现的比较棘手的问题，这些问题中的很多问题在NS仿真中都会出现，而且如果对ns理解不深入的话很难及时解决，NS高手season详细解答了这些问题，在ns仿真中会起到事半功倍的效果。-season to answer on the NS simulation appears more difficult issues in many of the problems in the NS simulation will occur, but if ns does not understand the depth resolved in a timely manner, then it is very difficult, NS masters season to answer these questions in detail, in ns simulation will play effectively.

基于linux平台用QT编写的串口通信代码，去年我使用Qt编写串口通信程序时，将自己的学习过程写成了教程（Qt编写串口通信程序全程图文讲解），但是由于时间等原因，我只实现了Windows下的串口通信，并没有去做Linux下的。自从教程发布到网上后，就不断有人提出相关的问题，而其中问的最多的就是，怎样在Linux下实现串口通信。因为有计划安排，而且没有开发板，所以一直没能去研究，也就没能给出很好的解决办法。前些天，网友hqwfreefly 用Qt写了一个叫linucom的Linux下串口调试程序，实现了Linux的串口通信。而且，正好现在我有几天假期，所以就和hqwfreefly合作，将linucom更新为Lincom，并且推出了Windows下的Wincom，然后完成了这篇Qt编写串口通信程序的专题教程，也算完成了我的一个心愿。

移动通信基本知识:从通信网的角度看，移动网可以看成是有线通信网的延伸，它由无线和有线两部分组成。无线部分提供用户终端的接入，利用有限的频率资源在空中可靠地传送话音和数据；有线部分完成网络功能，包括交换、用户管理、漫游、鉴权等，构成公众陆地移动通信网PLMN。从陆地移动通信的具体实现形式来分主要有模拟移动通信和数字移动通信这两部种。-Basic knowledge of mobile communications: From the perspective of communication networks, mobile networks can be seen as an extension of wired communication network, which is both wireless and wired components. Part of user terminals to provide wireless access, frequency of use of limited resources in the air and reliable transmission of voice and data wired part of the completion of network functions, including switching, subscriber management, roaming, authentication and so on, constitute a public land mobile communication network PLMN. From land-based mobile communications to the specific forms of the main points have analog and digital mobile communications that two kinds of mobile communication.
