Task group 1 (WPAN/Bluetooth)

See also: IEEE 802.15.1

IEEE 802. Bluetooth is a wireless protocol utilizing short-range communications technology facilitating data transmission over short distances from fixed and/or mobile devices creating wireless 15. 1-2002 has derived a Wireless Personal Area Network standard based on the Bluetooth v1.1 specifications. Bluetooth is a wireless protocol utilizing short-range communications technology facilitating data transmission over short distances from fixed and/or mobile devices creating wireless It includes a medium access control and physical layer specification. The Media Access Control (MAC Data communication protocol sub-layer also known as the Medium Access Control is a sublayer of the Data Link Layer specified in the The Physical Layer is the first level in the seven-layer OSI model of computer networking. An updated version of this standard, based upon the additions incorporated into Bluetooth v1.2, was published as IEEE 802. Bluetooth is a wireless protocol utilizing short-range communications technology facilitating data transmission over short distances from fixed and/or mobile devices creating wireless 15. 1-2005. ^[1]

Following the publication of 802. 15. 1-2005, the IEEE Study Group 1b voted 90-0 to discontinue their relationship with the Bluetooth SIG, effectively meaning that the later versions of Bluetooth will not become future IEEE standards. The Institute of Electrical and Electronics Engineers or IEEE (read eye-triple-e) is an international Non-profit, professional organization The Bluetooth Special Interest Group (SIG is the body that oversees the development of Bluetooth standards and the licensing of the Bluetooth technologies

Task group 2 (Coexistence)

IEEE 802. 15. 2-2003 addresses the issue of coexistence of wireless personal area networks (WPAN) with other wireless devices operating in unlicensed frequency bands such as wireless local area networks (WLAN).

Task group 3 (High Rate WPAN)

3 (High Rate WPAN)

IEEE 802. 15. 3-2003 is a MAC and PHY standard for high-rate (1100 to 1055 Mb/s) WPANs.

3a (WPAN High Rate Alternative PHY)

IEEE 802. 15. 3a was an attempt to provide a higher speed UWB PHY enhancement amendment to IEEE 802. Ultra-wideband (aka UWB, ultra-wide band, ultraband, etc is a radio technology that can be used at very low energy levels for short-range high-bandwidth 15. 3 for applications which involve imaging and multimedia.

The IEEE 802. 15. 3a most commendable achievement was the consolidation of 23 UWB PHY specifications into two proposals using : Multi-Band Orthogonal Frequency Division Multiplexing (MB-OFDM) UWB, supported by the WiMedia Alliance, and Direct Sequence - UWB (DS-UWB), supported by the UWB Forum. Ultra-wideband (aka UWB, ultra-wide band, ultraband, etc is a radio technology that can be used at very low energy levels for short-range high-bandwidth The WiMedia Alliance is a non-profit open industry association that promotes and enables the rapid adoption regulation standardization and multi-vendor interoperability of ultra-wideband The UWB Forum was an industry organization dedicated to ensuring that Ultra-Wideband (UWB products from multiple vendors are truly interoperable

On January 19, 2006 IEEE 802. 15. 3a task group (TG3a) members voted to withdraw the December 2002 project authorization request (PAR) that initiated the development of high data rate UWB standards. Ultra-wideband (aka UWB, ultra-wide band, ultraband, etc is a radio technology that can be used at very low energy levels for short-range high-bandwidth The process was in total deadlock. There were two technology proposals on the table backed by two different industry alliances. One of them was willing to move forward with a joint proposal; the other was not and had sufficient votes to block forward progress. The task group finally agreed to duke it out in the market place. The Working Group concurred. The technology faces significant regulatory hurdles in addition. This was not a factor in this decision but from a standards perspective it probably was and is too early to write a UWB standard given the regulatory and market uncertainty in the world market. If there is a surviving approach in a year or two and the technology has proven itself to be commercially viable, then IEEE can come back and revisit whether it makes sense to create an IEEE standard.

3b (MAC Amendment)

The IEEE 802. 15. 3. b is working on an amendment to 802. 15. 3 to improve implementation and interoprability of the MAC. This will include minor optimizations while preserving backward compatibility. In addition, this amendment will correct errors, clarify ambiguities, and add editorial clarifications.

3c (WPAN Millimeter Wave Alternative PHY)

The IEEE 802. 15. 3 Task Group 3c (TG3c) was formed in March 2005. TG3c is developing a millimeter-wave-based alternative physical layer (PHY) for the existing 802. 15. 3 Wireless Personal Area Network (WPAN) Standard 802. 15. 3-2003. Standard completion is expected for May 2008.

This mmWave WPAN will operate in the new and 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 will allow 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.

Task group 4 (Low Rate WPAN)

4 (Low Rate WPAN)

IEEE 802. 15. 4-2003 (Low Rate WPAN) deals with low data rate but very long battery life (months or even years) and very low complexity. The first edition of the 802. 15. 4 standard was released in May 2003. In March 2004, after forming Task Group 4b, task group 4 put itself in hibernation.

The ZigBee set of high level communication protocols is based upon the specification produced by the IEEE 802. ZigBee is the name of a specification for a suite of high level communication protocols using small 15. 4 taskgroup.

The Internet Engineering Task Force (IETF) 6LoWPAN working group is working to specify methods for performing IPv6 networking over IEEE 802. 6lowpan is an acronym of IPv6 over Low power Wireless Personal Area Networks. 15. 4 networks. They have released RFC 4919 describing "the assumptions, problem statement, and goals for transmitting IP over IEEE 802. 15. 4 networks. In September 2007 the 6LoWPAN working group released the FRC4944 which defines the 6LoWPAN header compression scheme. Also in the IETF 70 held in December of 2007 at Vancouver a BoF was held to determine if a new working group should be established to work on a standard routing solution for 6LoWPAN. The new working group was decided to be formed and was named ROLL (Routing Over Lossy and Low-power links). First ROLL WG meeting was held in IETF 72. "

4a (WPAN Low Rate Alternative PHY)

The principal interest is in providing communications and high precision ranging / location capability (1 meter accuracy and better), high aggregate throughput, and ultra low power; as well as adding scalability to data rates, longer range, and lower power consumption and cost. IEEE 802154a (formally called IEEE 802154a-2007 is an amendment to IEEE 802

In March 2005, IEEE802. 15. 4a selected a baseline specification. The baseline is two optional PHYs consisting of a UWB Pulse Radio (operating in unlicensed UWB spectrum) and a Chirp Spread Spectrum (operating in unlicensed 2. Ultra-wideband (aka UWB, ultra-wide band, ultraband, etc is a radio technology that can be used at very low energy levels for short-range high-bandwidth 4GHz spectrum). 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. C-UWB is an acronym for Continuous Pulse Ultra-wideband technology In March 2007, 802. 15. 4a was approved as an amendment to IEEE Std 802. 15. 4-2006. ^[2]

4b (Revisions and Enhancements)

The IEEE 802. 15 task group 4b was chartered to create a project for specific enhancements and clarifications to the IEEE 802. 15. 4-2003 standard, such as resolving ambiguities, reducing unnecessary complexity, increasing flexibility in security key usage, considerations for newly available frequency allocations, and others. IEEE 802. 15. 4b was approved in June 2006 and was published in September 2006 as IEEE 802. 15. 4-2006.

Task group 5 (Mesh Networking)

Mesh Networking of Wireless Personal Area Networks (WPANs)

Task Group 6 (BAN)

This task group is focusing on BAN or Body Area Network Technologies. Mesh networking is a way to route data voice and instructions between nodes. The goal is a low-power and low-frequency short-range wireless standard. ^[3]
