MAC for 802.15.3c Applications

• Overview of some proposed applications
• Wireless gigabit ethernet replacement
• gt1 Gbps
• P-MP and/or
• P-P
• Digital video distribution
• With simultaneous analog TV option
• P-MP
• Real time high definition video
• 3-D
• Virtual reality
• Interactive scenarios

3

• Data downloads wireless firewire
• P-P
• Examples
• Ipod-like device
• Digital camcorder
• For near-term applications, it might be proposed
  that most applications will require either
• Short, high data rate bursts
• 2 Gbps or greater or
• Very long, but lower data rate streams
• 1 Gbps (possibly even lower)
• Very low latency
• Very high QOS

MAC for 802.15.3c ApplicationsQuestions and
Concerns

• What, in general, is the limiting factor for the
  proposed MAC in regards to maximum data rates?
• Latency
• Overhead
• QOS
• Others?
• Will the MAC, as is, support 2.5 Gbps data
  rates? What is maximum?
• Could subset of MAC be implemented that may ease
  data rate restrictions? At what costs?

5

• Is MAC most able to support multi-gigabit data
  rates for
• Burst-type transmissions vs
• Continuous streaming ?
• Or are both modes equally supported?
• Recommendations from 802.15 gurus on how to
  proceed
• What areas to watch
• Contacts and liaisons
• Champion for .3c application
