Wireless USB

The Certified Wireless USB logo

Wireless USB (Universal Serial Bus) is a short-range, high-bandwidth wireless radio communication protocol created by the Wireless USB Promoter Group, which is intended to increase the availability of general

USB-based technologies. It is unrelated to Wi-Fi and different from the Cypress Wireless USB offerings. It was maintained by the WiMedia Alliance which ceased operations in 2009. Wireless USB is sometimes abbreviated as WUSB, although the USB Implementers Forum discouraged this practice and instead prefers to call the technology Certified Wireless USB to distinguish it from the competing UWB standard.

Wireless USB was 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 was 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 though it has been adopted by Android for precise signaling [1]

Support for the standard was deprecated in Linux 5.4[2][3] and removed in Linux 5.7[4]
