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.

   利用简单的红外对管，实现双机通信，基于arduino mega2560，通过高精度温湿度传感器dht11来测量环境温湿度，在通过红外对管实现主从机信息的交换，具有很强的实用价值，成本十分低廉，操作也很简单。

3GPP LTE的MIMO Channel Model,是在SCM基础上进行的扩展，比SCM能支持更大的带宽及更高的频段-3GPP LTE of MIMO Channel Model, is based on SCM expansion than SCM can support a greater bandwidth and higher frequency bands

】　本文主要讨论了Modbus 通信协议的R TU 帧格式中常用的错误校验方法,即循环冗余校验法( CRC) 。 提出了Modbus 协议反转CRC 校验的方法,推导了反转CRC 校验快速计算表格,并用C 语言实现了基于快速查 表算法的循环冗余校验程序。-In this paper, we mainly discuss the Modbus communication protocol R TU frame format commonly used in error checking methods, namely, Cyclic Redundancy Check Code (CRC). Modbus protocol proposed inversion method CRC checksum, CRC checksum is derived fast computing inversion table, and C language to achieve a quick look-up table algorithm based on cyclic redundancy check procedure.

The programming port of all the FP PLC’s support OPEN MEWTOCOL-COM. This is very useful when you want to monitor PLC values/bits or to set PLC values or bits via your COMPUTER. You can use any language such as Basic, C, Pascal, Assembler or even if other suppliers of PLCs can send ASCII strings, they can talk to our PLCs to exchange data.-The programming port of all the FP PLC s support OPEN MEWTOCOL-COM.
