本标准定义了一个物理（PHY）和媒体访问控制（MAC）层，该层使用用于光无线通信的光学透明介质中10 000 nm至190 nm的波长。该标准能够在200米的无限制视线范围内以高达10 Gb/s的速度传输数据。它设计用于非协调和协调拓扑中的点对点和点对多点通信。对于具有多个对等协调器的协调拓扑，将有一个主协调器。该标准包括适应不同的信道条件，并在单个协调器范围内移动或在协调器之间移动时保持连接。

This standard defines a physical layer (PHY) and medium access control (MAC) sublayer using light wave-lengths from 10 000 nm to 190 nm in optically transparent media for optical wireless communications (OWC). The standard is capable of delivering data rates up to 2.192 Gb/s at distances in the range of 200 m unrestricted line-of-sight. It is designed for point-to-point and point-to-multipoint communications and adaptation to varying channel conditions.
