November 2000 doc.: IEEE 802.15-00/352r0 November 2000 Scope/Purpose of R2SG Provide a formal vehicle within IEEE 802.15 to track the activities of the Bluetooth™ SIG Radio2 Working Group (and related activities) and recommend appropriate action to 802.

Bluetooth Radio 2 and IEEE 802.15.3 Source: Francis Truntzer 3Nov00 November 2000 Bluetooth Radio 2 and IEEE 802.15.3 BSIG's Position: The BSIG's concern is fragmentation of the WPAN market Main issue in the relationship between BSIG and IEEE: The two organisations have different IP rules and fundamentally different decision making philosophies. This makes it difficult for the two organizations to work together on a single spec. Even if the BSIG and TG3 started from the same proposal and developed specs in parallel, there is no guarantee that the two resulting specs would be compatible. Tom Siep, Texas Instruments

Bluetooth Radio 2 and IEEE 802.15.3 (cont.) Source: Francis Truntzer 3Nov00 November 2000 Bluetooth Radio 2 and IEEE 802.15.3 (cont.) BSIG Proposal #1: TG3 to follow the same relationship model as TG1, where one organization follows the other. This would guarantee that we end up with compatible specs. It is the BSIG's preferred solution. BSIG Proposal #2: TG3 to develop a radio solution which is highly differentiated (e.g.> 40Mbit/sec data rate) from the BSIG's Radio 2 specification.

Bluetooth Radio 2 and IEEE 802.15.3 (cont.) Source: Francis Truntzer 3Nov00 November 2000 Bluetooth Radio 2 and IEEE 802.15.3 (cont.) However: For the BSIG to adopt such a specification, all contributors would have to sign an Open IP agreement. If backward compliant with BT 1.0, IEEE's 802.15.3 must avoid overlapping the BT 1.0 spec, or an IEEE 802.15.3 product would not pass BT qualification. If IEEE 802.15.3 is not backward compliant with BT 1.0, it would fragment the WPAN market, as there would be two incompatible WPAN specifications with little end-user differentiation.

Status of Radio2 Study Group November 2000 doc.: IEEE 802.15-00/352r0 November 2000 Status of Radio2 Study Group Group must re-authorize at the November meeting in Tampa. Recommendation: do not re-authorize Reasoning: MAC for TG3 is not based on Bluetooth™ Wireless Technology No more information on Bluetooth Radio2 is forthcoming in the near future When information is available from BSIG, this group can reconstitute Tom Siep, Texas Instruments Tom Siep, Texas Instruments

Future R2SG Reincarnation November 2000 Future R2SG Reincarnation Other possible purposes in the future: 2.0 Specification/Radio2 could be a supplement to 802.15.1a 2.0 Specification/Radio2 may become available to the IEEE in 2001 as another derivative work product or something else Tom Siep, Texas Instruments
