January 2005 doc.: IEEE 802.15-04/0055r0 September 2005 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. Robert Poor - NBT GRoup Robert Poor - Ember Corporation

TG4b Scope (continued) The considered corrections are: January 2005 doc.: IEEE 802.15-04/0055r0 September 2005 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.
