(The PDF of this standard is available at no cost compliments of the IEEE GET program at. The standard adheres to applicable eye safety regulations. The results show that using these modulations with OFDM provides a link robustness that is at least 6 dB better than DSSS-OPQSK, which was introduced in the original IEEE 802.15.4 2 standard. IEEE Std 802.15.4-2003 I EEE Standards 802.15.4TM IEEE Standard for Information technology Telecommunications and information exchange between systems Local and metropolitan area networks Specific requirements Part 15. 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. Division Multiplexing), which were introduced in IEEE 802.15.4g 1 SUN (Smart Utility Network) in 2015. 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. 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.
