wireless USB

The wireless version of the universal serial bus (USB). Using ultra-wideband (UWB) technology, wireless USB is used to transmit the content of a laptop screen to a TV set or to a USB device that is within line of sight. Up to two meters (6.6 ft.), wireless USB provides the same data rate as USB 2.0 (480 Mbps). Within 10 meters (33 ft.), it reduces to 110 Mbps.

More Than Enough Connections
Wireless USB (WUSB) uses a hub and spoke architecture that provides up to 127 point-to-point connections. In 2004, the wireless USB Promoter Group was initiated at the Intel Developer Forum, which included HP, Microsoft and others. See USB, WHDI, WiGig and WirelessHD.


The First Wireless USB Hub
Introduced in 2006, the Belkin transceiver plugs into a USB port on a laptop, while the hub is cabled to four external USB devices, such as a hard disk, keyboard or printer. (Image courtesy of Belkin Corporation, www.belkin.com)







Stream to the TV
Warpia's StreamHD transmits screen output to a receiver that plugs into the HDMI port of a TV. Everything on the laptop screen appears on the larger display. (Image courtesy of Warpia, Inc., www.warpia.com)

The 2.4-GHz WirelessUSB NX transceiver delivers robust performance along with ultra-low power consumption, aided by a fast 2 Mbps data rate to limit time spent transmitting and receiving.
Cypress also offers wired and wireless connectivity solutions ranging from its WirelessUSB radio system-on-chip, to West Bridge and EZ-USB FX2LP controllers that enhance connectivity and performance in multimedia handsets.
According to the company, the DW-5K incorporates 2.4 GHz WirelessUSB technology which gives it a 30-foot range, and uses radio frequency systems so is not susceptible to line of sight issues.
At the low end is WirelessUSB, a fast no-wires network that just plugs straight into your computer's USB port or games console.
But, overall, the wireless networking market is robust, and will also be helped by two more new technologies coming in 2003: WiMedia and WirelessUSB. WiMedia is likely to adopt Ultra Wide-Band as its physical layer sometime next year and offer near-half gigabit speeds for home entertainment center networking (see the November issue for details, available at wwpi.com).
today announced that Lite-On Technology Corporation, a leading PC peripheral and component manufacturer in Taiwan, has selected Cypress s 2.4-GHz WirelessUSB -NL radio-on-a-chip for its next-generation wireless keyboard and mouse set.
As with other Cypress WirelessUSB families, the WirelessUSB-NL device offers superior performance in the presence of common interference from 2.4-GHz sources such as WiFi, Bluetooth, cordless phones and microwaves.
WirelessUSB-NL also supports Cypress Agile HID protocol that allows existing WirelessUSB customers to get started quickly on their designs without any additional effort.
Using a frequency-hopping spread spectrum technology, the CY694X makes it possible to use multiple WirelessUSB devices in crowded offices and classrooms without fear of interference between devices.
