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.

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.
