  • March 24, 2008 Letter Ballot Voters Pool #39

  • IEEE 802.15 Voting members have an obligation to vote. Not returning two valid letter ballots in a sequence of three letter ballots will automatically terminate voting rights.

  • "No" votes require the submission of detailed comments as defined in the IEEE rules for Sponsor Ballots to be counted as valid.  Abstentions are only counted as valid if they are based on "lack of expertise".



Please read and follow these step by step instructions to complete and submit your vote on IEEE P802.15 Letter Ballot 39. 

The O-QPSK and MPSK PHY's are being defined as co-alternative by both the IEEE and the Chinese WPAN. The MPSK PHY is defined in the Chinese standard for the Wireless Medium Access Control (MAC) and the Physical Layer (PHY) Specifications for Low-Rate Wireless Personal Area Networks (Task number: 20070007-T-469). An informative translation of the MPSK PHY is included in Annex J. As such, editorial comments made w.r.t. Annex J will be addressed by TG4c. However, Technical comments w.r.t. Annex J will be forwarded to the Chinese WPAN Standards Body and may or may not result in a change to Annex J technically. All Editorial and Technical comments w.r.t. everything outside Annex J will be addressed by TG4c.
