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.
The standard is now obsolete, and no new hardware has been produced for many years, although it has been adopted by Android for precise signaling
Support for the standard was deprecated in Linux 5.4 and removed in Linux 5.7
