Market Needs (Usage models)
• From WFA usage models (2792r0):1. Wireless Docking
2. In Home Distribution of HDTV and other content
3. Rapid Upload and Download of large files to/from server
4. Backhaul Traffic (e.g. for Meshing, Enterprise, Small Office)
5. Campus / Auditorium deployments
6. Manufacturing Floor Automation
• Additional usages:– Distributed platforms (Advanced Docking)
– “Sync and Go” Over IP

Mapping the usages to rates
1. Wireless Docking 1. Simple KVM- 3-5 Gbps (wuxga)
• WQXGA can get up to 9.8 Gbps
2. Advanced (distributed platforms) – 5-8 Gbps
2. In Home Distribution – up to 10 Gbps (2792r0)
3. Rapid Upload/”Sync and go”- 5 Gbps (2-layer blue ray disc can store 50 Gbyte)
4. LAN traffic – Ethernet is already at 10 Gbps, .11 will follow.

VHT
• A new 802.11 PHY/MAC standard should support a data rate of at least 5 Gbps.– In order to be relevant 5 years from now
– To satisfy the emerging throughput-hungry applications
• For such a high rate there is no substitute for BW– The 60 GHz band has 7-9 GHz of unlicensed BW with quite high
output power and EIRP regulatory limits.

Suggested path for VHT
• To define standardized modifications to the 802.11 MAC and PHY layers to operate in the 60 GHz band to achieve at least 5Gbps of over -the-air data rate.

Broad Market Potential
• Platforms with >20GB HDD/SSD are everywhere• .11 is known to be IP over Wireless• Media appliances moving to HD content• Significant industry-wide incentive to drive
innovation into a commoditizing market of 11n (2010+)

Compatibility
• Backwards compatible to earlier IEEE 802.11 standards– Triple-band WiFi
• Precedent: .11b/g are single band standards 11n which came later is a dual band standard.

Submission
Distinct Identity
• Substantially different from other 802 standards– Proposed speeds are substantially higher than the maximum
802.11n rates ~ 10 times higher
– Addresses non-PAN market needs; e.g., traffic backhaul and campus/auditorium connectivity.

Technical Feasibility
• The availability of 7-9 GHz of unlicensed BW in the 60GHz band makes it very easy to achieve VHT.
• There are existing proprietary proofs of concept for wireless systems in 60GHz.– http://www.youtube.com/watch?

Economic Feasibility
• Current processes more than adequate to support Giga speed
• Low cost 60GHz transceivers proven by several vendors
• VHT products must hit same cost envelope as 11n
