标准范围

ISO/IEC 8802-11:2005规定了无线局域网（LAN）的介质访问控制（MAC）和物理特性，该标准是局域网和城域网系列标准的一部分。ISO/IEC 8802-11:2005中的介质访问控制单元旨在支持物理层单元，因为它们可能会根据频谱的可用性而采用。ISO/IEC 8802-11:2005包含五个物理层单元:四个无线电单元，工作在2400-2500 MHz频段，工作在5.15-5.25 GHz、5.25-5.35 GHz和5.725-5.825 GHz频段，以及一个基带红外（IR）单元。一个无线电单元采用跳频扩频（FHSS）技术，两个无线电单元采用直接序列扩频（DSSS）技术，另一个无线电单元采用正交频分复用（OFDM）技术。

The medium access control (MAC) and physical characteristics for wireless local area networks (LANs) are specified in ISO/IEC 8802-11:2005, which is part of a series of standards for local and metropolitan area networks. The medium access control unit in ISO/IEC 8802-11:2005 is designed to support physical layer units as they may be adopted dependent on the availability of spectrum. ISO/IEC 8802-11:2005 contains five physical layer units: four radio units, operating in the 2400-2500 MHz band and in the bands comprising 5.15-5.25 GHz, 5.25-5.35 GHz, and 5.725-5.825 GHz, and one baseband infrared (IR) unit. One radio unit employs the frequency-hopping spread spectrum (FHSS) technique, two employ the direct sequence spread spectrum (DSSS) technique, and another employs the orthogonal frequency division multiplexing (OFDM) technique.
