扩频技术的理论早在50年代前就被提出,但当时技术水平难以应用于实践。经过多年研究,美国首先将此技术用于高度可靠保密的军事通讯。随着技术的发展,无线扩频产品已广泛用于各个行业和部门。如:计算机局域网的无线链接,数据与话音的复接信道,电力、煤气、水利、油田、数据采集、传输及调度监控系统,金融网络互联,电视会议,远程医疗论断,应急或灾难急救等。无线扩频技术产品的优
The theory of spread spectrum technology was proposed as early as the 1950s, but at that time the technical level was difficult to apply to practice. After years of research, the United States first used this technology for highly reliable and confidential military communications. With the development of technology, wireless spread spectrum products have been widely used in various industries and departments. Such as: computer LAN wireless link, data and voice multiplexing channel, electricity, gas, water, oil, data acquisition, transmission and dispatch monitoring system, financial network interconnection, video conferencing, telemedicine thesis, emergency or disaster emergency and so on. Wireless Spread Spectrum technology products excellent
