标准摘要
[中文适用范围]： 本标准定义了在光透明介质中使用10000 nm至190 nm波长的光进行短距离光无线通信（OWC）的物理层（PHY）和媒体访问控制（MAC）子层。该标准能够提供足以支持音频和视频多媒体服务的数据速率，并考虑光链路的移动性、与各种光基础设施的兼容性、来自环境光等源的噪声和干扰造成的损伤，以及适应可见光链路和其他目标光波长独特需求的MAC子层。它还支持相机光通信，其中发射设备包含光源，接收器是带有镜头和图像传感器的数码相机。该标准遵守适用的眼睛安全规定。 [外文原描述]： A physical layer (PHY) and medium access control (MAC) sublayer for short-range optical wireless communications (OWC) in optically transparent media using light wavelengths from 10 000 nm to 190 nm are defined. The standard is capable of delivering data rates sufficient to support audio and video multimedia services and also considers mobility of the optical link, compatibility with various light infrastructures, impairments due to noise and interference from sources like ambient light, and a MAC sublayer that accommodates the unique needs of visible links as well as the other targeted light wavelengths. It also accommodates optical communications for cameras where transmitting devices incorporate light-emitting sources and receivers are digital cameras with a lens and image sensor. The standard adheres to applicable eye safety regulations.
