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.

顶部端口（USB）接口，这个接口的调试是PL的使用
TOP PORT (USB) 调试接口说明
本接口是利用PL-2303HX的USB转RS232的接口芯片设计实现了一个TTL(5V)的RS232串口，并且利用了PL-2303HX的2个GPIO口软件模拟了一个低速的I2C总线.该接口由USB接口提供5V电压，可自带2Kbit(24C02)数据备份EEPROM (单独读写通道,不占用I2C总线地址)。并可对外提供小于250mA的5V电压。尤其适合WIN-XP以后的没有并口和串口笔记本电脑。整机成本不到￥20RMB。
-TOP PORT (USB) interface debugging of this interface is the use of PL-2303HX the USB to RS232 interface chip design to achieve a TTL (5V) of the RS232 serial port, and use of PL-2303HX the two GPIO port software simulation of a low-speed I2C bus. The interface from the USB interface to provide 5V voltage, can bring their own 2Kbit (24C02) data backup EEPROM (separate read and write access, do not occupy I2C bus address). And may provide less than 250mA of 5V voltage. WIN-XP is particularly suitable for subsequent parallel and serial no notebooks. Machine costs less than ￥ 20RMB.
