Description: 目前的智能机在硬件上多采用双cpu的架构，一个是基带处理器，主要处理数字信号、语音信号的编码解码以及GSM通信协议，另一个是应用处理器，运行操作系统和各种应用程序。基带处理器、射频和其它外围芯片作为一个模块，成为GSM/GPRS modem，提供AT命令接口。网络的应用已经是一个需求的热点，而目前的GSM模块大多都能支持GPRS功能。应用处理器通过AT命令集与带GPRS功能的无线通讯模块通信，为实现网络的应用提供了一个最底层的支持。
-Intelligent machines in the current hardware on many dual-cpu architecture of a baseband processor are mainly deal with digital signals, voice signals, and GSM codecs communication protocol, and the other is the application processor, operating system and applications running procedures. Baseband processor, radio frequency and other peripheral chips, as a module, as a GSM/GPRS modem, provided by AT command interface. Application of network needs is a hot spot, and most of the current GSM module can support GPRS function. Application processor through the AT command set and functionality with GPRS wireless communication module, in order to achieve the application of the network provides a bottom support.

Baseband processor, radio frequency, and other peripheral chips, as a module, a GSM/GPRS modem, to provide AT command interface. Network application is a demand for hot spots, while most of the current GSM module can support GPRS functionality. Application processor through the AT command set and with GPRS-enabled wireless communication module communications, network applications in order to achieve one of the most underlying support.

Description: OpenBTS 是从基带收发站（BTS）向上，完全替代传统的 GSM 运营商的网络交换构架。替代传统的传递呼叫到运营商的移动交换中心（MSC)的方法，它是通过 SIP 和 VOIP 传递数据到 Asterisk PBX 的。项目是由 Harving Samra 和 David A. Burgess 启动的。其目的是把边远和发展中地区地区的GSM服务费用减少到每个用户每月在1美元以下。项目的最初开发者涉及执照事宜，在初期的相关工作中官司连连（现已解决），也就是说一些底层的 GSM 代码被重新改写过。-OpenBTS from baseband transceiver stations (BTS) upwards, completely replace the traditional GSM operator' s network switching architecture. Alternative to traditional route the call to the operator' s mobile switching center (MSC) method, which is passed through the SIP and VOIP Asterisk PBX to the data. Project is funded by Harving Samra and David A. Burgess started. Its purpose is to remote and developing regions region' s GSM service fees reduced to $ 1 per user per month or less. Developers involved in the project' s initial license issues related to the work in the initial lawsuit again and again (now resolved), that some of the underlying code has been rewritten over GSM.
