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

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
