TG4b ScopeThis 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.

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.
