The 802.15 Working Group (WG) on Wireless Specialty Networks (WSN) focuses on the development of open consensus standards addressing wireless networking for the emerging Internet of Things (IoT), allowing these devices to communicate and interoperate with one another, mobile devices, wearables; Optical Wireless Communications (OWC), Autonomous Vehicles, etc . The goal is to publish standards, recommended practices, or guides that have broad market applicability and deal effectively with the issues of coexistence and interoperability with other wired and wireless networking solutions. The WG has completed a large body of work. Many of its standards, particularly IEEE Std. 802.15.4, are widely deployed around the world. The WG strives to be an incubator for new technologies and applications and has published the first standard utilizing the THz RF frequency bands for high speed wireless interconnection and reconfiguration of data centers. 802.15 is also the first organization to produce global standards for OWC.
