Description: 关于无线承载网络
无线承载网络(Wireless Hosted Network)是指安装有无线局域网服务的Windows 7和Windows Server 2008 R2所提供的一种WLAN功能，具备两项主要功能：
第一、把一个物理无线网卡虚拟化成一个或多个虚拟无线网卡，称为虚拟的WiFi。
第二、借助无线网卡把当前接网络虚拟成为一个基于软件的无线接入点，称为虚拟AP或软AP。-On the wireless network
Radio bearer network (Wireless Hosted Network) refers to the installation of a wireless local area network service function of WLAN Windows 7 and Windows Server 2008 R2 provides, has two main functions:
First, a physical wireless network card virtual into one or more virtual wireless network card, called the virtual WiFi.
Second, the wireless network card to the access network based on virtual become a wireless access point software, called virtual AP or soft AP.

Description:
本系统为立体声调频收音机，设计采用RDA5807收音模块，与单片机相结合，使收音解调电路设计变的简单，实现FM收音并显示频率。我们通过矩阵键盘设定我们需要的频段，并设置音量大小，通过诺基亚5110液晶屏显示出来，并根据所显示接收信号的强度等级，判断收音所在地的信号强度。RDA5807模块具有65-108MHz全球FM接收频段相容的效果，具备噪声消除、软静音、低音增强、灵敏度高、噪声小、抗干扰能力强等功能，所以使用本模块很容易实现，且系统可靠稳定。-This system is designed using RDA5807 stereo FM radio, radio module, combined with MCU, the radio receiver demodulation circuit design becomes simple, realize the FM reception and display frequency. We set the frequency we need through the matrix keyboard, and set the volume size displayed by the NOKIA 5110 LCD screen, and according to the received signal strength display, signal strength to determine the location of the radio. RDA5807 module with 65-108MHz global FM receiving band compatible with the effect, noise elimination, soft mute, bass enhancement, high sensitivity, low noise, strong anti-interference ability and other functions, so the use of this module is very easy to implement, and the system is reliable and stable.
