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
Submission
Slide 18
Robert F. Heile, GTE
July 1999
doc.: IEEE 802.15-99/027r1
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
Submission
Slide 19
Robert F. Heile, GTE
July 1999
doc.: IEEE 802.15-99/027r1
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
Submission
Slide 20
Robert F. Heile, GTE
July 1999
doc.: IEEE 802.15-99/027r1
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
Submission
Slide 21
Robert F. Heile, GTE
July 1999
doc.: IEEE 802.15-99/027r1
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.

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.
