IEEE 802.15 - Task Group 3: High Rate WPAN

Task Group 3: High Rate WPAN

See also: UWB Forum and WiMedia Alliance

IEEE 802.15.3-2003 is a MAC and PHY standard for high-rate (11 to 55 Mbit/s) WPANs.

IEEE 802.15.3a was an attempt to provide a higher speed UWB PHY enhancement amendment to IEEE 802.15.3 for applications which involve imaging and multimedia. 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(MB-OFDM) and Direct Sequence UWB (DS-UWB), on the table backed by two different industry alliances and was withdrawn in January 2006.

IEEE 802.15.3b-2005 amendment was released on May 5, 2006. It enhanced 802.15.3 to improve implementation and interoperability of the MAC. This will include minor optimizations while preserving backward compatibility. In addition, this amendment corrected errors, clarified ambiguities, and added editorial clarifications.

IEEE 802.15.3c-2009 was published on September 11, 2009. 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. The IEEE 802.15.3 Task Group 3c (TG3c) was formed in March 2005. This mmWave WPAN operates in clear band including 57–64 GHz unlicensed band defined by FCC 47 CFR 15.255. The millimeter-wave WPAN will allow high coexistence (close physical spacing) with all other microwave systems in the 802.15 family of WPANs. In addition, the millimeter-wave WPAN allows very high data rate over 2 Gbit/s applications such as high speed internet access, streaming content download (video on demand, HDTV, home theater, etc.), real time streaming and wireless data bus for cable replacement. Optional data rates in excess of 3 Gbit/s will be provided.

Famous quotes containing the words task, group, high and/or rate:

    “Method goes far to prevent trouble in business: for it makes the task easy, hinders confusion, saves abundance of time, and instructs those that have business depending, both what to do and what to hope.”
    —William Penn (1644–1718)

    “Laughing at someone else is an excellent way of learning how to laugh at oneself; and questioning what seem to be the absurd beliefs of another group is a good way of recognizing the potential absurdity of many of one’s own cherished beliefs.”
    —Gore Vidal (b. 1925)

    “No man who acts from a sense of duty ever puts the lesser duty above the greater. No man has the desire and the ability to work on high things, but he has also the ability to build himself a high staging.”
    —Henry David Thoreau (1817–1862)

    “We all run on two clocks. One is the outside clock, which ticks away our decades and brings us ceaselessly to the dry season. The other is the inside clock, where you are your own timekeeper and determine your own chronology, your own internal weather and your own rate of living. Sometimes the inner clock runs itself out long before the outer one, and you see a dead man going through the motions of living.”
    —Max Lerner (b. 1902)
