1. Project: IEEE P802.15 Study Group for Wireless Personal Area Networks (WPANs) • Submission Title: TG4b Merged PHY Proposal • Date Submitted: 16 September 2004 • Source: • Francois Chin, Institute for Infocomm Research, Singapore • Liang Li, Helicomm • Clint Powell, Freescale • Andreas Wolf, Dr. Wolf & Associates GmbH, Germany • Re: Proposal and Discussion of equal higher data rates for PHY for 900 and 2400MHz bands • Abstract: The proposed parallel reuse of the 2.4 GHz 802.15.4 modulation technology in PSSS offers highly attractive performance improvement, fulfilling all key OEm requirements, and visibly increasing market opportunities. • Purpose: Proposal for consideration by TG4b • Notice: This document has been prepared to assist the IEEE P802.15.

2. PHY merged proposal • The merger includes ALL proposers of TG4b PHY • Andreas Wolf, Dr. Wolf & Associates • Francois Chin, Institute for Infocomm Research • Clint Powell, Freescale • Liang Li, Helicomm Francois Chin, Liang Li, Clint Powell, Andreas Wolf

3. Outline of the merged proposal • The existing IEEE802.15.4-2003 868/915 Mhz modes remain mandatory in the standard • Two new optional modes based on channel bandwidth will be defined • 2 MHz 235 kbit/s Coherent O-QPSK 16-chip COBI 15-04-507-03 • 600 kHz 234 kbit/s BPSK/ASK 32-chip PSSS 15-04-121-05 • The modes will be applied based on a channel table for todays regulatory domains • 915 MHz (North America) 2 MHz bandwidth • 868 MHz (Europe) 600 kHz bandwidth • The proposals enables the use of either mode (i.e. 2 MHz or 600 kHz) in new or changed regulatory domains once those become available • Consistent with the discussion in the TG4b task group,backward compatibility to the mandatory 20/40 kbit/s base modesis achieved by switching the Rx / Tx mode in the devices Francois Chin, Liang Li, Clint Powell, Andreas Wolf

4. TG4b PHY modes Frequency bands and data rates New TG4b PHY modes Francois Chin, Liang Li, Clint Powell, Andreas Wolf

5. PICS Table C.4 Radio Frequencies New TG4b PHY modes Francois Chin, Liang Li, Clint Powell, Andreas Wolf

6. Channel tables • Current number of channels of 32 is not sufficient • Ability to flexibly add channels for new or changed regulatory domains is required Proposed solution • Add PHY PIB attribute phyRegulatoryDomain • Table with following structure per phyRegulatoryDomain: Channel Centre PHY NumberFrequencyMode... • Current channel table in IEEE802.15.4-2003will be phyRegulatoryDomain = 0 Francois Chin, Liang Li, Clint Powell, Andreas Wolf

7. Timeline • Consolidated, consistent RF performance characterization:By November 2004 plenary • Draft PHY specification:By November 2004 plenary • Proposed Assitant Technical Editor for TG4b PHY:Clint Powell • Supported by Francois Chin, Andreas Wolf for the respective RF modes Francois Chin, Liang Li, Clint Powell, Andreas Wolf
