Connecting the last 5 meters • Certified High Speed USB • Most successful interface standard, about 3 billion ports • 480 MBit data rates • Certified Wireless USB: • High speed USB replacement (480 MBits/s), Any other questions? • Based on WiMedia Alliance OFDM UWB Technology • Not just wireless USB (low speed mice and keyboards) • Low power, short range, high data rates • Bluetooth: • Headsets, the current “killer” application (1 MBit/s) • Bluetooth now planning to use WiMedia UWB for higher data rates • Years away, must find an application space
The Drive Towards Short Range Wireless: Customer frustration with cables Potential Certified Wireless USB products for 2006/2007 • PCs and Peripherals • External Hard Drives, CD/DVD burners • Printers • MP3 • Digital Cameras
What makes Ultra Wideband so special? WLAN Band Band Band #1 #2 #3 -40dBm f 2400 3432 3960 4488 MHz MHz MHz MHz UWB is sometimes called an underlay technology, because it can transmit in the “noise floor” of narrow band signals. More BW translates to higher data rates even with simple modulation techniques
