  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. Robert Poor - Ember Corporation

  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. Robert Poor - Ember Corporation
