1997年国际电子电工工程师协会(IEEE)组织正式出台了其关于无线网络标准IEEE802.11,此将成为无线网联技术循序渐进发展和市场不断开拓的基础。日前各无线局域网网联产品的供应商们正积极研制其最新符合IEEE802.11标准的产品系列。由于新标准提供诸多优点及特性以供产品供应商选择,故未来的无线网络产品将会分阶段推出,并逐步满足向工业标准靠拢并提供可靠产品的过渡方式。IEEE802.11标准为无线局域网定义了物理层(PHY)及媒介接入控制层(MAC)的结构。PHY定义包含
In 1997, the International Institute of Electrotechnical Engineers (IEEE) formally promulgated its IEEE802.11 wireless network standard, which will become the basis for the gradual development of the wireless network connection technology and the constant development of the market. Recently, all wireless LAN networking products suppliers are actively developing its latest IEEE802.11-compliant product line. As the new standard offers many advantages and features for product suppliers to choose from, future wireless networking products will be phased in and gradually meet the transition to industry standards and provide reliable products. The IEEE 802.11 standard defines the structure of a physical layer (PHY) and a medium access control layer (MAC) for a wireless local area network. PHY definition contains
