Wireless USB

Wireless USB is a short-range, high-bandwidth wireless radio communication protocol version of the Universal Serial Bus (USB) created by the Wireless USB Promoter Group. It is unrelated to Wi-Fi and Cypress Wireless USB. It was maintained by the WiMedia Alliance which ceased operations in 2009. Wireless USB is based on the WiMedia Alliance's Ultra-WideBand (UWB) common radio platform, which is capable of sending 480 Mbit/s at distances up to 3 metres (9.8 ft) and 110 Mbit/s at distances up to 10 metres (33 ft). It is designed to operate in the 3.1 to 10.6 GHz frequency range, although local regulatory policies may restrict the legal operating range in some countries. Development and commercial adoption of Wireless USB declined after the dissolution of the WiMedia Alliance in 2009 and the industry's transition toward Wi-Fi, Bluetooth and 60 GHz wireless technologies such as WiGig. The standard is now considered obsolete. Wireless USB support in the Linux kernel was deprecated in version 5.4 and completely removed in version 5.7 due to a lack of active users and hardware.
