LR-WPAN Standards Work
IEEE 802.15 Task Groups 4a and 4b

• Marco Naeve and Jose A. Gutierrez
• Eaton - Innovation Center

2
IEEE 802.15.4a - Scope

• Develop an alternate physical layer (PHY) for
  data communication with precision ranging,
  extended range, enhanced robustness and mobility.
  The alternate PHY is an (optional) amendment to
  the current IEEE 802.15.4-2003 LR-WPAN standard.

3
IEEE 802.15.4a - Status

• Reviewed proposals of potential applications.
• Developed UWB channel model.
• Drafted technical requirements document.
• Reviewed preliminary proposals for solutions.
• Drafted selection criteria document.
• The expected completion date of the TG4a
  amendment is November of 2006.

4
IEEE 802.15.4 - Scope

• Resolve ambiguities, provide corrections,
  removing unnecessary complexity, and define
  enhancements to the current IEEE 802.15.4-2003
  standard. The revised standard will be backward
  compatible.
• The considered enhancements are limited to
• A method for shared time-base distribution.
• Extension of 2.4GHz derivative modulation
  yielding higher data rates for the lower
  frequency bands.
• Mechanism for communicating the revision level.
• Security enhancements.

5
IEEE 802.15.4b - Status

• Reviewed comments from various implementers of
  the IEEE 802.15.4-2003 standard.
• Selected baseline proposals.
• Currently drafting a revision document.
• The expected completion date of the TG4b
  revision is January of 2006.
