Study Group 1b Closing Report

• Tom Siep
• TMS Associates, LLC
• Chair SG1b

The Issue

• The IEEE 802.15 membership has informally
  indicated that the current relationship between
  it and the Bluetooth SIG must be changed to be
  more in line with other WG/SIGs
• The Bluetooth SIG has indicated that it will not
  entertain the same kind of relationship the WiFi
  has with its counterpart

4
Bluetooth SIG Concerns

• The SIG loses control of its own technology,
  perhaps to competing technologies
• The SIG has a unique relationship with the IEEE
  that currently allows it to maintain this control
• ANSWER Hybrid organization, defined later in
  this presentation
• IPR Pool Pollution
• IPR Pool guarantees no member will sue another
  member over IPR maters concerning essential IPR
• ANSWER IEEE involvement does not significantly
  enhance risk because
• Area to be worked is pre-defined by SIG
• Other companies are working in Short Distance
  Wireless that pose a risk to this, independent of
  where the work goes on
• Change in confidentiality agreements
• Bylaws of SIG must change to accommodate the new
  relationship
• ANSWER the additional value the IEEE brings to
  the quality of the spec make the change
  worthwhile.

5
The Cost of Failure

• For the IEEE
• Lose participation of the most successful short
  distance wireless technology
• (More) Bad press for IEEE 802 if/when spilt
  becomes public
• Lose the possibility of other 802.15 groups using
  Bluetooth higher layers (profiles)
• For the Bluetooth SIG
• Lose status of having an international standard
  (Current standard may be withdrawn)
• Lose inclusion in Coexistence Assurance studies
  if withdrawn (Bluetooth is no longer a mandatory
  coexistence analysis component)
• Lose ready access to other PHYs (such as UWB)
• Lose the peer review that IEEE has provided in
  the past (More than 2000 edits made to Bluetooth
  Spec as a result of IEEE review)
• Bad press for Bluetooth SIG abandons
  standardization

6
Proposal to Go Forward Hybrid Organization

• Formulate 802.15.1b to include an expert group,
  the Bluetooth Core Improvement WG (Formally Radio
  Improvements Group)
• 15.1b will have meetings
• At all Plenary 802 meetings
• Ad Hoc meetings primarily in European venues in
  lieu of Interims
• Work items will initiate with internal SIG study
  groups
• Same way SIG currently does work
• External visibility not required
• When work items are defined PAR process in IEEE
  802.15 begins
• All 802.15.1b meetings are open to everyone
• No changes is scope is allowed without both PAR
  and SIG agreement
• Both organizations review work of hybrid
  committee and go through their approval cycles as
  they currently do
• When work is completed on the Draft
• Sponsor Ballot and Bluetooth SIG adoption occur
  in parallel
• Changes required by Sponsor Ballot will be
  entered as Errata in Bluetooth system
• When Standard is complete
• Bluetooth SIG retains certification and logo
  rights
• Bluetooth SIG may pick and choose portions of
  Standard to adopt (just like WiFi)
• Bluetooth SIG may add or subtract requirements
  (just like WiFi)

The Benefits of Success

• For the IEEE
• Identification with most successful short
  distance wireless technology
• Possibility of other 802.15 groups using
  Bluetooth higher layers (profiles)
• Coexistence metrics measure more of the real
  world
• For the Bluetooth SIG
• Retains status of having an international
  standard
• Benefit from Coexistence Assurance studies by new
  standards as well as creation of baseline
  coexistence for their own technology
• Potential access to other PHYs, such as UWB

8
Next Steps

• SG Chair requested to lobby for adoption of
  proposal
• MOTION 802.15 authorizes the Chair of SG1b (Tom
  Siep) to contact the Bluetooth SIG to advocate
  the proposed new method of working together and
  report back to the WG at the March 05 meeting.
• Move SG1b, second Mike McInnis PASSED
