Ril设计思想解析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。
Ril intelligent design idea machine parsing the current hardware architecture more than a dual cpu, one baseband processor, the main digital signal processing, speech signal encoding and decoding as well as the GSM communication protocol, and the other is the application processor, running the operating system and a variety of applications. 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.

ADSL 接入技术已成为终端用户最主要的宽带接入技术。ADSL 技术的关键是ADSL 调制解调器,即ADSL
MODEM。ADSL 用户端调制解调器驱动器是一个宽频带功率放大器,他能不失真放大和传输电话线上已编码的数字信号。
本文通过对ADSL 调制解调器驱动器特点、结构和性能的分析,给出了一种ADSL 用户端MODEM 驱动器的实现电路。该
电路采用具有优良高频的双功率放大器L T1886 ,即使在配置高电平的闭环增益网络后也能保持较低的失真。
ADSL access technology has become the most important end-user broadband access technology. ADSL technology is the key to ADSL modem, that is, ADSLMODEM. ADSL modem client driver is a broadband power amplifier, the distortion that he can not enlarge and transfer telephone lines have been encoded digital signal. Based on the ADSL modem driver characteristics, structure and performance analysis, we give a ADSL client realize MODEM driver circuit. The circuit has an excellent high-frequency power amplifier of the dual-L T1886, even though high in the configuration of the closed-loop gain network also able to maintain low distortion.

iWebSMS2000是一个基于Web的短信平台
===============================================================================
目前政府、企业信息化，对消息的获取提出了更加严格的要求，需要随时随地、不受
空间、时间、地点的限制；要求主动获取消息，要求能在节省成本，同时保证信息安全，
在这种情况下，本公司自行研制开发了基于Web方式的iWebSMS2000短信消息平台管理方案。
这个方案是采用金格无线Modem作为短信收发设备，并在此基础上开发了金格短信服务器软
件和Web应用组件，支持JavaBean或COM调用方式，提供高可靠的扩展性，方便了政府、企
业和软件开发商应用集成。
iWebSMS2000 is a Web-based messaging platform =========== ======================================== =========================== government, corporate information, Access to information made more stringent requirements, the need anywhere from space, time and location constraints; Active demand access to information requests in cost savings, while ensuring the security of information, in this case, The company developed its own Web-based information to the SMS platform iWebSMS2000 management programs. The program is the use of lattice as a wireless modem SMS transceiver equipment, and on this basis the development of the lattice messaging server software and Web application components, COM support JavaBean or call approach to the provision of highly reliable, scalable, convenience of the gove (2006-08-28, MultiPlatform, 825KB, 下载36次)
