  1. Project: IEEE P802.15 Working Group for Wireless Personal Area Networks (WPANs) Submission Title: [802.15 MAC for 60 GHz Gigabit WLAN/WPAN] Date Submitted: [January 18, 2005] Source: [Bruce Bosco] Company: [Motorola] Address: [2100 East Elliot Road, Tempe, AZ, 85044, USA] Voice:[480-413-5241], FAX: [480-413-4288], E-Mail:[bruce.a.bosco@motorola.com] Re: [] Abstract: [Liaison report on 802.15 MAC for use for 802.15.3c WLAN/WPAN applications] Purpose: [To report on the status of MAC alignment to the needs of 802.15.3c] Notice: This document has been prepared to assist the IEEE P802.15. It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s).

  2. MAC for 802.15.3c Applications • Overview of some proposed applications: • Wireless gigabit ethernet replacement • >1 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 Bruce A. Bosco, Motorola

  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 Bruce A. Bosco, Motorola

  4. 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? Bruce A. Bosco, Motorola

  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 Bruce A. Bosco, Motorola
