IEEE 802.15.4b was approved in June 2006 and was published in September 2006 as IEEE 802.15.4-2006. The Pulsed UWB Radio is based on Continuous Pulsed UWB technology (see C-UWB) and will be able to deliver communications and high precision ranging. The selected baselines are two optional PHYs consisting of a UWB Pulse Radio (operating in unlicensed UWB spectrum) and a Chirp Spread Spectrum (operating in unlicensed 2.4В GHz spectrum). The principal interest was in providing higher precision ranging and localization capability (1 meter accuracy and better), higher aggregate throughput, adding scalability to data rates, longer range, and lower power consumption and cost. IEEE 802.15.4a (formally called IEEE 802.15.4a-2007) is an amendment to IEEE 802.15.4 specifying additional physical layers (PHYs) to the original standard. Audio/visual (AV) mode (OFDM, up to 3.8 Gbit/s).High speed interface (HSI) mode (single carrier, up to 5 Gbit/s).Single carrier (SC) mode (up to 5.3 Gbit/s).A total of three PHY modes were defined in the standard:

The millimeter-wave WPAN allows very high data rate, short range (10 m) for applications including high speed internet access, streaming content download (video on demand, HDTV, home theater, etc.), real time streaming and wireless data bus for cable replacement. Depending on the geographical region, anywhere from 2 to 9В GHz of bandwidth is available (for example, 57вЂ“64В GHz is available as unlicensed band defined by FCC 47 CFR 15.255 in North America). This mmWave WPAN is defined to operate in the 57вЂ“66В GHz range. The IEEE 802.15.3 Task Group 3c (TG3c) was formed in March 2005. The task group TG3c developed a millimeter-wave-based alternative physical layer (PHY) for the existing 802.15.3 Wireless Personal Area Network (WPAN) Standard 802.15.3-2003.

a method for a device to return information about signal quality of a received packet.

faster network recover in the case when the piconet coordinator (PNC) abruptly disconnects.

a method for relinquishing channel time to another device in the PAN.

multiple contention periods in a superfame.

logical link control/ subnetwork access protocol (LLC/SNAP) headers.

implied acknowledgment policy that allow polling.

a new MAC layer management entity (MLME) service access point (SAP).

Among other changes, the amendment defined the following new features: This amendment include many optimizations, corrected errors, clarified ambiguities, and added editorial clarifications while preserving backward compatibility. It enhanced 802.15.3 to improve implementation and interoperability of the MAC. See also: UWB Forum and WiMedia Alliance IEEE 802.15.3b-2006 Documents related to the development of IEEE 802.15.3a are archived on the IEEE document server. The members of the task group were not able to come to an agreement choosing between two technology proposals, Multi-band Orthogonal Frequency Division Multiplexing (MB-OFDM) and Direct Sequence UWB (DS-UWB), backed by two different industry alliances and was withdrawn in January 2006. IEEE P802.15.3a was an attempt to provide a higher speed Ultra wideband PHY enhancement amendment to IEEE 802.15.3 for applications which involve imaging and multimedia. The standard can be downloaded via the IEEE Get program, which is funded by IEEE 802 volunteers. IEEE 802.15.3-2003 is a MAC and PHY standard for high-rate (11 to 55 Mbit/s) WPANs. The IEEE 802.15.2-2003 standard was published in 2003 and task group two went into 'hibernation'. Task group two addresses the coexistence of wireless personal area networks (WPAN) with other wireless devices operating in unlicensed frequency bands such as wireless local area networks (WLAN).
