2. doc.: IEEE 802.15-05-0674-01-004b TG4b September 2005 Robert Poor - NBT GRoupSlide 2 TG4b Scope This project will define enhancements and corrections to the existing standard. The revised standard will be backward compatible with IEEE P802.15.4-2003. The considered enhancements shall be limited to: A method for shared time-base distribution. Support for new frequency allocations for Europe, China, and Japan. Extension of 2.4GHz derivative modulation yielding higher data rates for the lower frequency bands. Mechanism for communicating the revision level.

3. doc.: IEEE 802.15-05-0674-01-004b TG4b September 2005 Robert Poor - NBT GRoupSlide 3 TG4b Scope (continued) The considered corrections are: Resolving ambiguities. Removing unnecessary complexity, such as making GTS support optional and eliminating BUSY_RX, BUSY_TX, and FORCE_TRX_OFF from the PHY enumerations. Resolving issues such as long association time for non-beacon networks, inflexible security use, adding support for multicast, reducing MAC overhead and MAC header compression.

4. doc.: IEEE 802.15-05-0674-01-004b TG4b September 2005 Robert Poor - NBT GRoupSlide 4 TG4b Purpose The purpose of this revision is to extend the market applicability of IEEE 802.15.4-2003 and to remove ambiguities in the standard. Implementations of the current approved standard have revealed potential areas of improvements. Additional frequency bands are being made available in various countries that are attractive for this application space.

Patents IEEE standards may include the known use of essential patents, and patent applications, provided the IEEE receives assurance from the patent holder or applicant with respect to patents essential for compliance with both mandatory and optional portions of the standard. This assurance shall be provided without coercion and prior to approval of the standard (or reaffirmation when a patent becomes known after initial approval of the standard). This assurance shall be a letter that is in the form of either a) A general disclaimer to the effect that the patentee will not enforce any of its present or future patent(s) whose use would be required to implement the proposed IEEE standard against any person or entity using the patent(s) to comply with the standard or b) A statement that a license will be made available without compensation or under reasonable rates, with reasonable terms and conditions that are demonstrably free of any unfair discrimination This assurance shall apply, at a minimum, from the date of the standard's approval to the date of the standard's withdrawal and is irrevocable during that period.
