LR-WPAN Standards Work IEEE 802.15 Task Groups 4a and 4b Marco Naeve and Jose A. Gutierrez Eaton - Innovation Center
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. Marco Naeve, Jose A. Gutierrez
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. Marco Naeve, Jose A. Gutierrez
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. Marco Naeve, Jose A. Gutierrez
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. Marco Naeve, Jose A. Gutierrez
