Heile, GTE

  18. Task Group vs Working Group The 802.11 WG and the WPAN SG: • agreed on the need for a WPAN Standard • agreed that there is a strong market demand for a consumer-cost, low power solution • agreed on a PAR to accomplish that task • agreed on the importance of Coexistence and the need for etiquette in the use of a shared medium • disagree on the venue to best create a WPAN Standard Robert F. Heile, GTE

  19. Market Hypotheses • A WPAN Standard that does not involve Bluetooth as a participant will have a tough time gaining market acceptance • Multiple independent efforts will aggravate coexistence and interference issues Robert F. Heile, GTE

  20. Imperatives for Success • Need a forum that can attract members who feel they have equal standing • Need to get active participation from Members of Bluetooth, HomeRF/Firefly, 802.11, etc • Need a forum which can take a fresh look, evaluate different proposals and find compromise solutions that address broad market applicability as well as technical merits • Speed is of the essence--1-2years maximum Robert F. Heile, GTE

  21. The Advantages of a WG • Has the stature required to work more effectively with significant external groups • Easier to act as the agent of compromise • Greater freedom of action • Singular purpose promotes speed and efficiency Robert F. Heile, GTE

  22. The Bottom Line Strongly urge the SEC to pass a motion to form a WPAN Working Group • Finding effective compromise solutions is imperative to shared use, interoperability, success and acceptance. • The perception of balance needs to be assured. • The issue is not whether a lite version of .11 can do the job, more important is market acceptance of a standard that does the job. • Multiple WPAN standards are likely to address this space. Robert F. Heile, GTE

  23. P802.15 Working Group on Wireless Personal Area Networks approved March 18, 1999 • Austin, TX, April 14, 1999 - IEEE P802 LAN/MAN Standards Committee (LMSC) is pleased to announce the formation of a new Working Group to develop standards for Wireless Personal Area Networks for portable and mobile computing devices. Portable and mobile computing devices are defined as unobtrusive computing devices, networking devices, software and peripherals which are worn or carried by individuals to enhance their ability to perform productive work as well as provide entertainment. • The new group is designated P802.15 Working Group on Wireless Personal Area Networks. The Standards created by P802.15 will address the requirements for Wireless Personal Area Networking (WPAN) of PCs, PDAs, peripherals, cell phones, pagers and consumer electronic devices to communicate and interoperate with one another. http://standards.ieee.org/announcements/802.15.html Robert F.
