  1. VHT Applications Authors: Date: 2007-09-07 Gal Basson (Wilocity)

  2. Abstract This presentation discusses some possible future (5-10 years out) applications that require very high throughput (above 1 Gbs) and are beyond the capability of 802.11n. Gal Basson (Wilocity)

  3. Terminology • Application – a source or sink of wireless data that relates to a particular type of user activity • Usage Model – A specification of one or more applications and environments from which a simulation scenario can be created once the traffic patterns of the applications are known. Usage models are created to encompass use cases. • Latency- The time from when a packet was sent till it has been received w/o an error Gal Basson (Wilocity)

  4. Very High Throughput applications • High speed wireless cable replacement • Monitors • HDTV • projectors • Wireless Docking • “Simple” docking • Dividing the platform • “Sync and go” applications • Fast point to point transfer • Gbps-WLAN Gal Basson (Wilocity)

  5. High Speed cables replacements • HDMI • 5-10 Gbps • ~1 msec latency • Wireless KVM (Keyboard Video, Mouse) • 5-10-20 Gbps • 1 msec latency • Wireless projector • 5-10 Gbps • ~1 msec latency Gal Basson (Wilocity)

  6. Wireless docking • Simple docking (KVM) • 3-5Gbps • ~1 msec latency • Distributed platform (Advanced Docking) • External Disks and DVDs • Computing expansions • Extended graphics performance • 3-5 Gbps • Very low latency in the order of 10 usec Gal Basson (Wilocity)

  7. “Sync and Go” • Ad-hoc traffic • Players (Video, Mp3) • VideoCams • 2-5 Gbps • Latency on the order of 1 msec Gal Basson (Wilocity)

  8. Wireless LAN (GiFi) • Media networking • More video content • Computing networking • Thin clients, Virtualization networking • Peer to Peer connection • Copy content • Match Wired GbE performance • 2Gbps IP based Gal Basson (Wilocity)

  9. Summary • In 5-10 years, the need for Gbps-WLAN is obvious • Various applications that exist today + more we can’t think of now… • Holograms ???? • Who knows.. • Need 10X over 11n to be still relevant in 10 years • 3-5Gbps • Is there a substitute to higher BW ? • Is it reasonable to expect a factor of 5-10 increase in data rate in the 5 GHz band used by two prior 802.11 standards? • Increasing bandwidth is the most straightforward method for increasing rate, as we do not get unlimited robust gains from spatial multiplexing. Gal Basson (Wilocity)
