新的无线局域网标准（二）

　　The 802.11b standard benefits users by delivering wireless ethernet speeds of 11M bit/sec that can reliably support everyday business applications, e-mail, internet and server network access.

　　With support from the new wireless ethernet from the new wireless ethernet compatibility alliance, founded by 3com, lucent, nokia and several other companies in the wireless LAN business, the new standard will also promise certified interoperability across multivendor platforms.

　　Finally, the 802.11b standard serves as a clamoring for a simplified wireless LAN landscpape.

　　Vendors can now focus on a single, high-speed standard, and users can cut through the clutter of wireless options by fovusing on a standard that delivers multibvendor interoperability and the performance to meet their application needs.

　　有了便携式和无线局域网，用户在离开其办公桌的时候，不管是在会议室、公共区域还是在远处办公室，都能享有更高的生产效率。

　　然而，时至今日，无线局域网对多数企业应用来说还是太慢。依据IEEE802.11标准，他们运行速度为1兆至2兆位/秒。

　　现在对此标准的一个新的更高速扩展，能让无线网支持高达11兆位/秒的数据速率。

　　最初的802.11标准是在1997年提出的，通过定义能与常规的上层企业协议组一起工作的低级协议体系结构，把无线行业团结起来了。802.11也保持了与三种最流行的无线电传输方式（直接顺序扩频、跳频扩频和红外线）的兼容性。
