Wireless USB- is a short-range, high-bandwidth wireless radio communication protocol created by the Wireless USB Promoter Group. Wireless USB is sometimes abbreviated as "WUSB", although the USB Implementers Forum discourages this practice and instead prefers to call the technology "Certified Wireless USB" to differentiate it from competitors. 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 meters and 110 Mbit/s at up to 10 meters. 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 for any given country. An upcoming 1.1 specification will increase speed to 1 Gbit/s and working frequencies up to 6 GHz.
WirelessUSB "WirelessUSB" another technology produced by Cypress Semiconductor is not related to "Certified Wireless USB". Cypress's "WirelessUSB" is a protocol that uses the 2.4 GHz band with a range from 10 meters (at max 1 Mbit/s) to 50 meters (at max 62.5 kbit/s) and is designed for Human Interface Devices (HIDs), with current offerings from companies such as Belkin, Logitech, Gyration Inc., and Virtual Ink. Cypress's chipset is also used for short-range automated synchronization and data transfers in products like Garmin's Astro GPS tracking system.
Wireless USB from the USB-IF With more than 2 billion legacy wired USB connections in the world today, USB is the de facto standard in the personal computing industry. Soon, these same, fast, interoperable connections will become available in the wireless world, with the introduction of Wireless USB from the USB-IF. Wireless USB is the new wireless extension to USB that combines the speed and security of wired technology with the ease-of-use of wireless technology. Wireless connectivity has enabled a mobile lifestyle filled with conveniences for mobile computing users. Wireless USB will support robust high-speed wireless connectivity by utilizing the common WiMedia MB-OFDM Ultra-wideband (UWB) radio platform as developed by the WiMedia Alliance. UWB technology offers a solution for high bandwidth, low cost, low power consumption, and physical size requirements of next-generation consumer electronic devices. Wireless USB is the first high-speed wireless personal interconnect technology to meet the needs of multimedia consumer electronics, PC peripherals, and mobile devices.Wireless USB will preserve the functionality of wired USB while also unwiring the cable connection and providing enhanced support for streaming media CE devices and peripherals.Wireless USB performance is targeted at 480Mbps at 3 meters and 110Mbps at 10 meters.
