November 2004 TG4b Scope [TG4b] 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. 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.

November 2004 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. [Ref: IEEE 15-04-0037-00-004b] Robert Poor, Ember Corporation
