IEEE Standards and Emerging Technologies: ZigBee and WBANPresented bySk Jahid AhmedRoll No. : 001110701024Department of E.T.C.E, Jadavpur UniversityIt is the era of wireless technology. Life is becoming faster everyday. From Wi-Fi to Bluetooth to the most recent Body area network the uprising technology has made our life advanced and easy indeed.

All the above mentioned technologies are related through wireless space technologies.

Introduction

We need different modules for implementing these technologies in real life scenario.

Engineers and researchers have defined several standards for these modules based on data rates, power consumption, load and reliability of the network.

TheInstitute of Electrical and Electronics Engineers Standards Association(IEEE-SA) is an organization withinIEEEthat develops globalstandardsin a broad range of industries, including: power and energy, biomedicalandhealth care,information, technology, telecommunication, transportation, nanotechnology, information assurance and many more.

Among the entire IEEE standards family the most important in modern day scenario is undoubtedly the IEEE 802 family. IEEE 802 standards deal with local area networks(LAN) and metropolitan area networks.

The most widely used standards are for the Ethernet family, Token Ring, Wireless LAN, and Bluetooth .

What is the need for the standards?

Make or break networking products

Inter operability and relations among all these technologies

Vendor independence in designing and manufacturing the products

Providing a common ground for manufacturers to have a standardization

The services and protocols specified in IEEE 802 map to the lower two layers (Data Link and Physical) of the seven-layerOSInetworking reference model. In fact, IEEE 802 splits the OSI Data Link Layer into two sub-layers namedLogical Link Control(LLC) andMedia Access Control(MAC), so that the layers can be listed like this:

Data link layer LLC Sublayer MAC Sublayer

The 802 Wireless spaceWe will mainly focus on IEEE 802.15 i.e. the family of Wireless Personal Area Networks, more precisely on ZigBee and Body Area Network

Bluetooth is the most significant and common in this family.

ZigBee is one of the low data wireless technologies most discussed and researched in recent days.

Body Area Network is newest in the family and still needs a lot of research for proper modification.

What is ZigBee?Technological Standard Created for Control and Sensor Networks (lights, switches, thermostats, appliances).

ZigBee is based on anIEEE 802.15.4 standard.

Named for erratic, zig-zagging patterns of bees between flowers.

Future of ZigBeeWireless Body Area Network (IEEE 802.15.6)Increasing population and the rising costs of health care have triggered the introduction of novel technology-driven enhancements to current health care practices.Recent advances in electronics have enabled the development of small and intelligent (bio) medical sensors which can be worn on or implanted in the human body.Thus introduced Wireless Body Area Network (WBAN).Wireless Body Area Network (WBAN) has great potential to revolutionize the future of healthcare technology. Earlier, IEEE 802 had many success stories in developing international standards on wireless communication. Examples include IEEE 802.11, IEEE 802.15.1 and IEEE 802.15.4 standards. The purpose of the IEEE 802.15.6 was to define new Physical (PHY) and Medium Access Control (MAC) layers for WBAN.

The current IEEE 802.15.6 standard defines three PHY layersNarrowband (NB)Ultra wideband (UWB) Human Body Communications (HBC) layers.

The selection of each PHY depends on the application requirements. On the top of it, the standard defines a sophisticated MAC protocol that controls access to the channel.

In IEEE 802.15.6, PHY is responsible forThe activation and deactivation of the radio transceiverClear channel assessmentData reception and transmission.
