5 UWB vs. Bluetooth Bluetooth Over 300M unit shipment at 2005 Blooming 2 ~ 3 years latter than expectation All brand new SW protocol stacks are big efforts/issues to design and interoperability New applications UWB learned from Bluetooth Very strong collaboration with legacy applications USB, 1394, & UPnP/IP 5

6 UWB vs. WLAN WLAN Over 80M unit shipment at i to improve security e to enhance QoS support UWB learned from WLAN AES engine (802.11i) adaptation Provide TDMA-based QoS service Much better than WLAN QoS due to its total different MAC infrastructure 6

7 UWB Market forecast (in Million) UWB TAM The use of Ultra Wide Band (UWB) communications systems will exceed 150 million devices by (Parks Associates) In 2008, 90% of the W-USB applications will belong to PC related market Source: ABI (2005/1); Parks Associates 7

12 Opportunity & Thread of UWB Technical view PHY: Ultra-high data rate (O) Video streaming Short range means higher total capability (O/T) PAN ad-hoc application VLSI implementation challenges on RF, ADC/DAC, & BBP (T) World-wide regulatory issues (T) MAC/WiMCA/WUSB/SMP: True QoS (Quality of Service) (O) Streaming latency is controlled Block-ACK policy (O) Efficient throughput/data rate ratio MAC is too capable/complex (O/T) Suitable for many applications, too costly, large interoperability loadings Link to legacy protocols (O) Use of infrastructure means short time-to-market 12
