Issues Found Ambiguities in the standard that need to be resolved 01/2004 Issues Found Ambiguities in the standard that need to be resolved Clarify ambiguity on promiscuous mode. Add CHANNEL_ACCESS_FAILURE as valid status to the MLME-SCAN.confirm primitive for active scans. Unnecessary complexity Make support for GTS optional for FFDs. Eliminate BUSY_RX, BUSY_TX, and FORCE_TRX_OFF from the PHY enumerations to reduce complexity. Drop beacons payload during MAC scanning. Marco Naeve, Eaton Corp.

01/2004 Issues Found Association time in non-beacon networks is too long for some applications. Security key use is inflexible Add CCM* mode. Multicast is not supported by the MAC but is desired for many applications MAC headers and beacon payloads could create significant overhead Investigate MAC header compression to reduce overhead. Marco Naeve, Eaton Corp.

Proposed additional capabilities 01/2004 Proposed additional capabilities PHY/MAC layer shared time base distribution method Support for new frequency allocations in Europe Support for new frequency allocations in China Use a 2.4 GHz PHY derivative for the lower frequency bands to yield higher data rate and simplify the design of multi-band devices Marco Naeve, Eaton Corp.
