Bandwidth Demand – Audio Arena

• ATRAC3/MP3 Music Download– 128kbps for Playback (Selectable)– For “Checking-out” (5MB/music x 15 titles)

• 10Mbps takes 1 minute Too Long?• 60Mbps takes 10 seconds Comfortable

• CD (74 Minute Audio: About 700MB)– 1.4Mbps for Playback– For “Checking-out”

• 9Mbps takes 10 minutes Too Long?• 90Mbps takes 1 minute Comfortable

– 1GB Compact Flash/Memory Stick will be the Media for HiFi Audio

†Adequate Digital Rights Management Required for All the Examples

Bandwidth Demand – Still Image Arena

• Digital Still Image Download/Upload– 3Mega Pixels Picture Creates 1.4MB File– 128MB Memory Stick Accommodates 80

Pictures• 15Mbps takes 60 seconds Too Long?

• 90Mbps takes 10 seconds Comfortable

– 1Giga Pixels will be in a year or 2

Bandwidth Demand – Motion Picture Arena

• DVD (MPEG Contents: 8.5GB)– 6-10Mbps for Playback

• DV Camcorder– 27Mbps

• MicroMV Camcorder (MPEG2 Format)– 12Mbps

• Digital TV– Streaming Continuously Occupies the

Frequency– Standard MPEG2: 4-8 Mbps– High Definition MPEG2: 20-24Mbps

• US and Japanese DTV†Adequate Digital Rights Management Required for Digital TV

Power Consumption Demand• Power Sensitive Products

– Cam Corder (1,200-4,000mAh Battery)• 3.5W-4.5W for Recording• < 10% for Wireless Monitoring?

– Digital Still Camera (600-700mAh Battery)• 1.5W-2W• < 10% for Wireless Download?

– PDA (800-1,400mAh Battery)• 10-15 Days Battery Life/Full Recharge (30min./day use)• < 100mW for Wireless Download?

– Entertainment Robot• 9W (Battery Life: 90 Minutes/Full Recharge )• Wireless may Always be Active while Robot is Active • < 1% for Wireless Control?

Functional Requirements 1• Lower Power Consumption

– < Several 100mW Order including MAC Covers the Application Areas beyond 802.11

• Bandwidth– >100Mbps is Desirable

• The Best Remedy for the QoS• Scalability is Required for the Variety of Applications• Support Multiple Multimedia Streaming• The More Bandwidth Provides the More Capability but…

– Trade off with the Power Consumption and the Cost– The Next Paradigm could be Non-Encoded Video (>1Gbps)

• Size, Footprint of the Radio– Memory Stick Size is Desirable

• 5 cm x 2.15 cm x 0.28 cm

Functional Requirements 2• Cost

– Bluetooth Level is Desirable and Competitive– Depends on the Degree of Demand and Satisfaction

• QoS– Need Appropriate Error Correction but…

• Trade off with the Cost and Power Consumption• Solution should be Brought by the Combination between

PHY/MAC and the Higher Layer– Through a Wall is Required for Home Environment

• >10m is the Original Requirement of 802.15.3

• Others– Coexistence is a Mandatory to Live with Incumbent

Devices• 2.4GHz/5GHz…• Cellular, GPS…
