'''ZigBee''', is a wireless open standard and a competing protocol to Bluetooth, which fall under wireless personal area network (WPAN) classification. It is a standard for mesh networking, with allows for self configuring networks, ease of installation and configuration. It is designed for low power applications, especially applications that are designed for very long batter life. It has a low data rate of 20-250Kbps, depending on the band. The protocol is designed with security in mind.<br />
<br />
<br />
ZigBee is defined and promoted by the ZigBee Alliance, a group of over 150 companies. The latest version of the ZigBee specification is ZigBee-2007. The current push is for industrial plants where low cost and long battery life remote sensors are required for process control and preventative machine maintenance.<br />

'''802 Wireless Standards Family'''<br />
<br>Zigbee is designed to operate near other wireless standards. [2]]]<br />
<br />
ZigBee implements the IEEE 802.15.4 WPAN standard, which specifies the media-access control (MAC) and physical-layer. This ensures interoperability with other stand-compliant products. This standard specifies operation in the unlicensed bands:<br />
* 2.4 GHz for global use<br />
* 915 MHz for N. America, Australia, and a few other counties<br />
* 868 MHz for EU countries [2]<br />
<br />
ZigBee specification is defined and promoted by ZigBee Alliance. The alliance is an independent, vendor-neutral and non-profit corporation founded in 2002. [2] Adopters of ZigBee technology must license the technology by becoming members of the alliance. Manufactures must apply for ZigBee certification, which is meant to satisfy the minimum conformance to ZigBee standard. This in indented to promote device interoperability, and reputation of ZigBee standard. <br />
<br />
The actual specification is available for non-profit use. The brief history of the specification is:<br />
<br />
* The ZigBee specifications were ratified on 14 December 2004.<br />
* The ZigBee Alliance announces public availability of Specification 1.0 on 13 June 2005, known as ZigBee 2004 Specification.<br />
* The ZigBee Alliance announces the completion and immediate member availability of the enhanced version of the ZigBee Standard in September 2006, known as ZigBee 2006 Specification.<br />
* During the last quarter of 2007, ZigBee PRO, the enhanced ZigBee specification was finalized. [7]<br />
<br />
=== Protocol ===<br />
<br />
[[Image:Zigbee_stack.gif |thumb|250px|right|<br />
'''Simplified ZigBee protocol stack''' [4]]]<br />
<br />
ZigBee standard provides network and application layer. The network layer deals with security management, message broker, routing information and general network management. The security is done at both network and application level, using AES-128 symmetric keys for authentication and encryption. [2] Since it is defined in the specification, all ZigBee products will provide as minimum, which allows for a very secure environment. Developers can provide more security features at the application level. <br />
<br />
ZigBee's interface to the end-use is at the Application layer. In order to facilitate interoperability between devices that accomplish a specific task, ZigBee standard has defined Application Profiles [1], similar to Bluetooth Profiles. Application Profile is an agreement on a series of messages defining an application space. For example, ''Home Automation'' profile allows a light sensor product from one vendor to work with light controller product from another vendor. [2] ZigBee offer two types of Application Profiles:<br />
<br />
# Public Application Profiles<br/> These are defined by ZigBee Standard and intended for consumer's information purpose. Currently, only ''Home Automation'' profile is defined. Some other profiles in development are ''Telecommunication Services'', and ''Personal Home Healthcare''[2].<br />
# Manufacturing Specific Profiles<br/> These are private application profiles developed for a company. These may be proprietary, often intended for plant use.<br />
<br />
=== Interoperability ===<br />
<br />
Zigbee is designed to operate near other devices. ZigBee falls within the 802 family of standards, which includes Wi-Fi and Bluetooth. <br />
<br />
There has been some speculation that use of 2.4Ghz bandwidth introduces significant interference. Such claims have been refuted by a paper released by ZigBee alliance.[6]<br />
<br />
== Comparing ZigBee and Bluetooth ==<br />
<br />
ZigBee is intented for different applications than Bluetooth, even though have some commonalities, such as band they use. Some of the key differences are: [1]<br />
<br />
{| valign="top"<br />
|-<br />
|<ul><ol start="1"><li>'''ZigBee''' provides very low duty cycle, very long battery life (100-1000 days)<li>Static and dynamic star and mesh networks, over 65000 nodes, and low latency<li>Ability to remain on stand-by for long periods with communication<li>Direct Sequence Spread Spectrum allows devices to sleep with need for close synchronization</ol></ul><br />
|<ul><ol start="1"><li>'''Bluetooth''' provides moderate duty cycle, moderate battery life (1-7 days)<li>Very high Quality of Service and very low latency<li>Static star network with up to seven clients<li>Frequency Hopping Spread Spectrum is extremely difficult to create extended networks without large synchronization cost</ol></ul><br />
|}<br />
<br />
ZigBee does have overlapping features with Bluetooth. Most notably, the currently developed ''Telecom Profile'' is expected to provide peer-to-peer small data sharing feature. "Small files such as ring tones, images, address book contacts and other information provided by telecom operators is shared easily between two ZigBee-enabled mobile devices". [8]<br />
<br />
== Wireless Sensor Market ==<br />
<br />
With the WSN market grow to an estimated $4.6 billion in 2011, up from $500 million in 2007 [8], ZigBee is a strong contender to become the standard for WSN. Companies can adopt this protocol into its products in an attempt to gain the market share. Also, industrials plants can gain the benefits from better monitoring and control of process, thanks to the lost cost and easy of deployment of wireless sensor networks based on ZigBee. <br />

'''ZigBee''', is a wireless open standard and a competing protocol to Bluetooth, which fall under wireless personal area network (WPAN) classification. It is a standard for mesh networking, with allows for self configuring networks, ease of installation and configuration. It is designed for low power applications, especially applications that are designed for very long batter life. It has a low data rate of 20-250Kbps, depending on the band. The protocol is designed with security in mind.<br />
<br />
<br />
ZigBee is defined and promoted by the ZigBee Alliance, a group of over 150 companies. The latest version of the ZigBee specification is ZigBee-2007. The current push is for industrial plants where low cost and long battery life remote sensors are required for process control and preventative machine maintenance.<br />

'''ZigBee Target Markets''' [2]]]<br />
<br />
It is intended to be used for home entertainment and monitoring sensors, mobile services such as m-payment and m-healthcare, commercial building monitoring such as HVAC and access control. <br />
For manufacturing the current application is for low power, low data rate wireless sensor networks (WSN).<br />
<br />
<br />
== Technical Information ==<br />
<br />
ZigBee is based on radio frequency (RF) technology and mesh networking.<br />
It is a suite of protocols that covers from the physical layer, network layer to the application layer. The physical layer is an implementation of IEEE 802.15.4 (Bluetooth is covered under IEEE 802.15.1).<br />
<br />
=== Overview ===<br />
<br />
* Band – 868, 902-928MHz, and 2.4GHz <br />
* Topology – Ad-hoc, Star, Point to Point, Mesh <br />
* Data Rate – 20/40Kb/s and 250Kb/s <br />
* Power Consumption – Very Low <br />
* Range – 10-100+ meters <br />
* Security – very high; AES-128 level encryption <br />
* Size – up to 64K nodes in a single logical network<br />
<br />
<br />
=== Standards ===<br />
<br />
[[Image:Zigbee_interoperability.jpg|thumb|300px|right|<br />
'''802 Wireless Standards Family'''<br />
<br>Zigbee is designed to operate near other wireless standards. [2]]]<br />
<br />
ZigBee implements the IEEE 802.15.4 WPAN standard, which specifies the media-access control (MAC) and physical-layer. This ensures interoperability with other stand-compliant products. This standard specifies operation in the unlicensed bands:<br />
* 2.4 GHz for global use<br />
* 915 MHz for N. America, Australia, and a few other counties<br />
* 868 MHz for EU countries [2]<br />
<br />
ZigBee specification is defined and promoted by ZigBee Alliance. The alliance is an independent, vendor-neutral and non-profit corporation founded in 2002. [2] Adopters of ZigBee technology must license the technology by becoming members of the alliance. Manufactures must apply for ZigBee certification, which is meant to satisfy the minimum conformance to ZigBee standard. This in indented to promote device interoperability, and reputation of ZigBee standard. <br />
<br />
The actual specification is available for non-profit use. The brief history of the specification is:<br />
<br />
* The ZigBee specifications were ratified on 14 December 2004.<br />
* The ZigBee Alliance announces public availability of Specification 1.0 on 13 June 2005, known as ZigBee 2004 Specification.<br />
* The ZigBee Alliance announces the completion and immediate member availability of the enhanced version of the ZigBee Standard in September 2006, known as ZigBee 2006 Specification.<br />
* During the last quarter of 2007, ZigBee PRO, the enhanced ZigBee specification was finalized. [7]<br />
<br />
=== Protocol ===<br />
<br />
<br />
[[Image:Zigbee_stack.gif |thumb|250px|right|<br />
'''Simplified ZigBee protocol stack''' [4]]]<br />
<br />
ZigBee standard provides network and application layer. The network layer deals with security management, message broker, routing information and general network management. The security is done at both network and application level, using AES-128 symmetric keys for authentication and encryption. [2] Since it is defined in the specification, all ZigBee products will provide as minimum, which allows for a very secure environment. Developers can provide more security features at the application level. <br />
<br />
ZigBee's interface to the end-use is at the Application layer. In order to facilitate interoperability between devices that accomplish a specific task, ZigBee standard has defined Application Profiles [1], similar to Bluetooth Profiles. Application Profile is an agreement on a series of messages defining an application space. For example, ''Home Automation'' profile allows a light sensor product from one vendor to work with light controller product from another vendor. [2] ZigBee offer two types of Application Profiles:<br />
<br />
# Public Application Profiles<br/> These are defined by ZigBee Standard and intended for consumer's information purpose. Currently, only ''Home Automation'' profile is defined. Some other profiles in development are ''Telecommunication Services'', and ''Personal Home Healthcare''[2].<br />
# Manufacturing Specific Profiles<br/> These are private application profiles developed for a company. These may be proprietary, often intended for plant use.<br />
<br />
=== Topology ===<br />
<br />
<br />
<br />
<br />
=== Interoperability ===<br />
<br />
Zigbee is designed to operate near other devices. ZigBee falls within the 802 family of standards, which includes Wi-Fi and Bluetooth. <br />
<br />
There has been some speculation that use of 2.4Ghz bandwidth introduces significant interference. Such claims have been refuted by a paper released by ZigBee alliance.[6]<br />
<br />
== Comparing ZigBee and Bluetooth ==<br />
<br />
ZigBee is intented for different applications than Bluetooth, even though have some commonalities, such as band they use. Some of the key differences are: [1]<br />

'''802 Wireless Standards Family'''<br />
<br>Zigbee is designed to operate near other wireless standards. [2]]]<br />
<br />
ZigBee implements the IEEE 802.15.4 WPAN standard, which specifies the media-access control (MAC) and physical-layer. This ensures interoperability with other stand-compliant products. This standard specifies operation in the unlicensed bands:<br />
* 2.4 GHz for global use<br />
* 915 MHz for N. America, Australia, and a few other counties<br />
* 868 MHz for EU countries [2]<br />
<br />
ZigBee specification is defined and promoted by ZigBee Alliance. The alliance is an independent, vendor-neutral and non-profit corporation founded in 2002. [2] Adopters of ZigBee technology must license the technology by becoming members of the alliance. Manufactures must apply for ZigBee certification, which is meant to satisfy the minimum conformance to ZigBee standard. This in indented to promote device interoperability, and reputation of ZigBee standard. <br />
<br />
The actual specification is available for non-profit use. The brief history of the specification is:<br />
<br />
* The ZigBee specifications were ratified on 14 December 2004.<br />
* The ZigBee Alliance announces public availability of Specification 1.0 on 13 June 2005, known as ZigBee 2004 Specification.<br />
* The ZigBee Alliance announces the completion and immediate member availability of the enhanced version of the ZigBee Standard in September 2006, known as ZigBee 2006 Specification.<br />

<br />
ZigBee standard provides network and application layer. The network layer deals with security management, message broker, routing information and general network management. The security is done at both network and application level, using AES-128 symmetric keys for authentication and encryption. [2] Since it is defined in the specification, all ZigBee products will provide as minimum, which allows for a very secure environment. Developers can provide more security features at the application level. <br />
<br />
ZigBee's interface to the end-use is at the Application layer. In order to facilitate interoperability between devices that accomplish a specific task, ZigBee standard has defined Application Profiles [1], similar to Bluetooth Profiles. Application Profile is an agreement on a series of messages defining an application space. For example, ''Home Automation'' profile allows a light sensor product from one vendor to work with light controller product from another vendor. [2] ZigBee offer two types of Application Profiles:<br />
<br />
# Public Application Profiles<br/> These are defined by ZigBee Standard and intended for consumer's information purpose. Currently, only ''Home Automation'' profile is defined. Some other profiles in development are ''Telecommunication Services'', and ''Personal Home Healthcare''[2].<br />
# Manufacturing Specific Profiles<br/> These are private application profiles developed for a company. These may be proprietary, often intended for plant use.<br />

<br />
'''ZigBee''', is a wireless open standard and a competing protocol to Bluetooth, which fall under wireless personal area network (WPAN) classification. It is a standard for mesh networking, with allows for self configuring networks, ease of installation and configuration. It is designed for low power applications, especially applications that are designed for very long batter life. It has a low data rate of 20-250Kbps, depending on the band. The protocol is designed with security in mind.<br />
<br />
<br />
ZigBee is defined and promoted by the ZigBee Alliance, a group of over 150 companies. The latest version of the ZigBee specification is ZigBee-2007. The current push is for industrial plants where low cost and long battery life remote sensors are required for process control and preventative machine maintenance.<br />
<br />
== Uses ==<br />
<br />
<br />
[[Image:Zigbee_target_markets.jpg|thumb|300px|right|<br />
'''ZigBee Target Markets''' [2]]]<br />
<br />
It is intended to be used for home entertainment and monitoring sensors, mobile services such as m-payment and m-healthcare, commercial building monitoring such as HVAC and access control. <br />
For manufacturing the current application is for low power, low data rate wireless sensor networks (WSN).<br />
<br />
<br />
== Technical Information ==<br />
<br />
ZigBee is based on radio frequency (RF) technology and mesh networking.<br />
It is a suite of protocols that covers from the physical layer, network layer to the application layer. The physical layer is an implementation of IEEE 802.15.4 (Bluetooth is covered under IEEE 802.15.1).<br />
<br />
=== Overview ===<br />
<br />
* Band – 868, 902-928MHz, and 2.4GHz <br />
* Topology – Ad-hoc, Star, Point to Point, Mesh <br />
* Data Rate – 20/40Kb/s and 250Kb/s <br />
* Power Consumption – Very Low <br />
* Range – 10-100+ meters <br />
* Security – very high; AES-128 level encryption <br />
* Size – up to 64K nodes in a single logical network<br />
<br />
<br />
=== Standards ===<br />
<br />
[[Image:Zigbee_interoperability.jpg|thumb|300px|right|<br />
'''802 Wireless Standards Family'''<br />
<br>Zigbee is designed to operate near other wireless standards. [2]]]<br />
<br />
ZigBee implements the IEEE 802.15.4 WPAN standard, which specifies the media-access control (MAC) and physical-layer. This ensures interoperability with other stand-compliant products. This standard specifies operation in the unlicensed bands:<br />
* 2.4 GHz for global use<br />
* 915 MHz for N. America, Australia, and a few other counties<br />
* 868 MHz for EU countries [2]<br />
<br />
ZigBee specification is defined and promoted by ZigBee Alliance. The alliance is an independent, vendor-neutral and non-profit corporation founded in 2002. [2] Adopters of ZigBee technology must license the technology by becoming members of the alliance. Manufactures must apply for ZigBee certification, which is meant to satisfy the minimum conformance to ZigBee standard. This in indented to promote device interoperability, and reputation of ZigBee standard. <br />
<br />
The actual specification is available for non-profit use. The brief history of the specification is:<br />
<br />
* The ZigBee specifications were ratified on 14 December 2004.<br />
* The ZigBee Alliance announces public availability of Specification 1.0 on 13 June 2005, known as ZigBee 2004 Specification.<br />
* The ZigBee Alliance announces the completion and immediate member availability of the enhanced version of the ZigBee Standard in September 2006, known as ZigBee 2006 Specification.<br />
* During the last quarter of 2007, ZigBee PRO, the enhanced ZigBee specification was finalized. [7]<br />
<br />
=== Protocol ===<br />
<br />
<br />
[[Image:Zigbee_stack.gif |thumb|250px|right|<br />
'''Simplified ZigBee protocol stack''' [4]]]<br />
<br />
ZigBee standard provides network and application layer. The network layer deals with security management, message broker, routing information and general network management. The security is done at both network and application level, using AES-128 symmetric keys for authentication and encryption. [2] Since it is defined in the specification, all ZigBee products will provide as minimum, which allows for a very secure environment. Developers can provide more security features at the application level. <br />
<br />
ZigBee's interface to the end-use is at the Application layer. In order to facilitate interoperability between devices that accomplish a specific task, ZigBee standard has defined Application Profiles [1], similar to Bluetooth Profiles. Application Profile is an agreement on a series of messages defining an application space. For example, ''Home Automation'' profile allows a light sensor product from one vendor to work with light controller product from another vendor. [2] ZigBee offer two types of Application Profiles:<br />
<br />
# Public Application Profiles<br/> These are defined by ZigBee Standard and intended for consumer's information purpose. Currently, only ''Home Automation'' profile is defined. Some other profiles in development are ''Telecommunication Services'', and ''Personal Home Healthcare''[2].<br />
# Manufacturing Specific Profiles<br/> These are private application profiles developed for a company. These may be proprietary, often intended for plant use.<br />
<br />
=== Topology ===<br />
<br />
<br />
<br />
<br />
=== Interoperability ===<br />
<br />
Zigbee is designed to operate near other devices. ZigBee falls within the 802 family of standards, which includes Wi-Fi and Bluetooth. <br />
<br />
There has been some speculation that use of 2.4Ghz bandwidth introduces significant interference. Such claims have been refuted by a paper released by ZigBee alliance.[6]<br />
<br />
== Comparing ZigBee and Bluetooth ==<br />
<br />
ZigBee is intented for different applications than Bluetooth, even though have some commonalities, such as band they use. Some of the key differences are: [1]<br />
<br />
{| valign="top"<br />
|-<br />
|<ul><ol start="1"><li>'''ZigBee''' provides very low duty cycle, very long battery life (100-1000 days)<li>Static and dynamic star and mesh networks, over 65000 nodes, and low latency<li>Ability to remain on stand-by for long periods with communication<li>Direct Sequence Spread Spectrum allows devices to sleep with need for close synchronization</ol></ul><br />
|<ul><ol start="1"><li>'''Bluetooth''' provides moderate duty cycle, moderate battery life (1-7 days)<li>Very high Quality of Service and very low latency<li>Static star network with up to seven clients<li>Frequency Hopping Spread Spectrum is extremely difficult to create extended networks without large synchronization cost</ol></ul><br />
|}<br />
<br />
ZigBee does have overlapping features with Bluetooth. Most notably, the currently develop ''Telecom Profile'' is expected to provide peer-to-peer small data sharing feature. "Small files such as ring tones, images, address book contacts and other information provided by telecom operators is shared easily between two ZigBee-enabled mobile devices". [8]<br />
<br />
== Wireless Sensor Market ==<br />
<br />
With the WSN market grow to an estimated $4.6 billion in 2011, up from $500 million in 2007 [8], ZigBee is a strong contender to become the standard for WSN. Companies can adopt this protocol into its products in an attempt to gain the market share. Also, industrials plants can gain the benefits from better monitoring and control of process, thanks to the lost cost and easy of deployment of wireless sensor networks based on ZigBee. <br />

<br />
'''ZigBee''', is a wireless open standard and a competing protocol to Bluetooth, which fall under wireless personal area network (WPAN) classification. It is a standard for mesh networking, with allows for self configuring networks, ease of installation and configuration. It is designed for low power applications, especially applications that are designed for very long batter life. It has a low data rate of 20-250Kbps, depending on the band. The protocol is designed with security in mind.<br />
<br />
<br />
ZigBee is defined and promoted by the ZigBee Alliance, a group of over 150 companies. The latest version of the ZigBee specification is ZigBee-2007. The current push is for industrial plants where low cost and long battery life remote sensors are required for process control and preventative machine maintenance.<br />
<br />
== Uses ==<br />
<br />
<br />
[[Image:Zigbee_target_markets.jpg|thumb|300px|right|<br />
'''ZigBee Target Markets''' [2]]]<br />
<br />
It is intended to be used for home entertainment and monitoring sensors, mobile services such as m-payment and m-healthcare, commercial building monitoring such as HVAC and access control. <br />
For manufacturing the current application is for low power, low data rate wireless sensor networks (WSN).<br />
<br />
<br />
== Technical Information ==<br />
<br />
ZigBee is based on radio frequency (RF) technology and mesh networking.<br />
It is a suite of protocols that covers from the physical layer, network layer to the application layer. The physical layer is an implementation of IEEE 802.15.4 (Bluetooth is covered under IEEE 802.15.1).<br />
<br />
=== Standards ===<br />
<br />
[[Image:Zigbee_interoperability.jpg|thumb|300px|right|<br />
'''802 Wireless Standards Family'''<br />
<br>Zigbee is designed to operate near other wireless standards. [2]]]<br />
<br />
ZigBee implements the IEEE 802.15.4 WPAN standard, which specifies the media-access control (MAC) and physical-layer. This ensures interoperability with other stand-compliant products. This standard specifies operation in the unlicensed bands:<br />
* 2.4 GHz for global use<br />
* 915 MHz for N. America, Australia, and a few other counties<br />
* 868 MHz for EU countries [2]<br />
<br />
ZigBee specification is defined and promoted by ZigBee Alliance. The alliance is an independent, vendor-neutral and non-profit corporation founded in 2002. [2] Adopters of ZigBee technology must licence the technology by becoming members of the alliance. Manufactures must apply for ZigBee certification, which is meant to satisfy the minimum conformance to ZigBee standard. This in indented to promote device interoperability, and reputation of ZigBee standard. <br />
<br />
The actual specification is available for non-profit use. The brief history of the specification is:<br />
<br />
* The ZigBee specifications were ratified on 14 December 2004.<br />
* The ZigBee Alliance announces public availability of Specification 1.0 on 13 June 2005, known as ZigBee 2004 Specification.<br />
* The ZigBee Alliance announces the completion and immediate member availability of the enhanced version of the ZigBee Standard in September 2006, known as ZigBee 2006 Specification.<br />
* During the last quarter of 2007, ZigBee PRO, the enhanced ZigBee specification was finalized. [7]<br />
<br />
=== Protocol ===<br />
<br />
<br />
[[Image:Zigbee_stack.gif |thumb|250px|right|<br />
'''Simplified ZigBee protocol stack''' [4]]]<br />
<br />
ZigBee standard provides network and application layer. The network layer deals with security management, message broker, routing information and general network management. The security is done at both network and application level, using AES-128 symmetric keys for authentication and encryption. [2] Since it is defined in the specification, all ZigBee products will provide as minimum, which allows for a very secure environment. Developers can provide more security features at the application level. <br />
<br />
ZigBee's interface to the end-use is at the Application layer. In order to facilitate interoperability between devices that accoplish a specific task, ZigBee standard has defined Application Profiles [1], similar to Bluetooth Profiles. Application Profile is an agreement on a series of messages defining an application space. For example, ''Home Automation'' profile allows a light sensor product from one vendor to work with light controller product from another vendor. [2] ZigBee offer two types of Application Profiles:<br />
<br />
# Public Application Profiles<br/> These are defined by ZigBee Standard and intended for consumer's information purpose. Currently, only ''Home Automation'' profile is defined. Some other profiles in development are ''Telecommunication Services'', and ''Personal Home Healthcare''[2].<br />
# Manufacturing Specific Profiles<br/> These are private application profiles developed for a company. These may be proprietary, often intended for plant use.<br />
<br />
=== Topology ===<br />
<br />
<br />
<br />
<br />
=== Interoperability ===<br />
<br />
Zigbee is designed to operate near other devices. ZigBee falls within the 802 family of standards, which includes Wi-Fi and Bluetooth. <br />
<br />
There has been some speculation that use of 2.4Ghz bandwidth introduces significant interferance. Such claims have been refuted by a paper released by ZigBee alliance.[6]<br />
<br />
== Comparing ZigBee and Bluetooth ==<br />

'''ZigBee''', is a wireless open standard and a competing protocol to Bluetooth, which fall under wireless personal area network (WPAN) classification. It is a standard for mesh networking, with allows for self configuring networks, ease of installation and configuration. It is designed for low power applications, especially applications that are designed for very long batter life. It has a low data rate of 20-250Kbps, depending on the band. The protocol is designed with security in mind.<br />
<br />
<br />
ZigBee is defined and promoted by the ZigBee Alliance, a group of over 150 companies. The latest version of the ZigBee specification is ZigBee-2007. The current push is for industrial plants where low cost and long battery life remote sensors are required for process control and preventative machine maintenance.<br />

It is intended to be used for home entertainment and monitoring sensors, mobile services such as m-payment and m-healthcare, commercial building monitoring such as HVAC and access control. <br />
For manufacturing the current application is for low power, low data rate wireless sensor networks (WSN).<br />
<br />
<br />
== Technical Information ==<br />
<br />
ZigBee is based on radio frequency (RF) technology and mesh networking.<br />
It is a suite of protocols that covers from the physical layer, network layer to the application layer. The physical layer is an implementation of IEEE 802.15.4 (Bluetooth is covered under IEEE 802.15.1).<br />

'''802 Wireless Standards Family'''<br />
<br>Zigbee is designed to operate near other wireless standards. [2]]]<br />
<br />
ZigBee implements the IEEE 802.15.4 WPAN standard, which specifies the media-access control (MAC) and physical-layer. This ensures interoperability with other stand-compliant products. This standard specifies operation in the unlicensed bands:<br />
* 2.4 GHz for global use<br />
* 915 MHz for N. America, Australia, and a few other counties<br />
* 868 MHz for EU countries [2]<br />
<br />
ZigBee specification is defined and promoted by ZigBee Alliance. The alliance is an independent, vendor-neutral and non-profit corporation founded in 2002. [2] Adopters of ZigBee technology must licence the technology by becoming members of the alliance. Manufactures must apply for ZigBee certification, which is meant to satisfy the minimum conformance to ZigBee standard. This in indented to promote device interoperability, and reputation of ZigBee standard. <br />
<br />
The actual specification is available for non-profit use. The brief history of the specification is:<br />
<br />
* The ZigBee specifications were ratified on 14 December 2004.<br />
* The ZigBee Alliance announces public availability of Specification 1.0 on 13 June 2005, known as ZigBee 2004 Specification.<br />
* The ZigBee Alliance announces the completion and immediate member availability of the enhanced version of the ZigBee Standard in September 2006, known as ZigBee 2006 Specification.<br />
* During the last quarter of 2007, ZigBee PRO, the enhanced ZigBee specification was finalized. [7]<br />
<br />
=== Protocol ===<br />
<br />
<br />
[[Image:Zigbee_stack.gif |thumb|250px|right|<br />
'''Simplified ZigBee protocol stack''' [4]]]<br />
<br />
ZigBee standard provides network and application layer. The network layer deals with security management, message broker, routing information and general network management. The security is done at both network and application level, using AES-128 symmetric keys for authentication and encryption. [2] Since it is defined in the specification, all ZigBee products will provide as minimum, which allows for a very secure environment. Developers can provide more security features at the application level. <br />
<br />
ZigBee's interface to the end-use is at the Application layer. In order to facilitate interoperability between devices that accoplish a specific task, ZigBee standard has defined Application Profiles [1], similar to Bluetooth Profiles. Application Profile is an agreement on a series of messages defining an application space. For example, ''Home Automation'' profile allows a light sensor product from one vendor to work with light controller product from another vendor. [2] ZigBee offer two types of Application Profiles:<br />
# Public Application Profiles<br />
These are defined by ZigBee Standard and intended for consumer's information purpose. Currently, only ''Home Automation'' profile is defined. Some other profiles in development are ''Telecommunication Services'', and ''Personal Home Healthcare''[2].<br />
# Manufacturing Specific Profiles<br />
These are private application profiles developed for a company. These may be proprietary, often intended for plant use.<br />
<br />
=== Topology ===<br />
<br />
<br />
<br />
<br />
=== Interoperability ===<br />
<br />
Zigbee is designed to operate near other devices. ZigBee falls within the 802 family of standards, which includes Wi-Fi and Bluetooth. <br />
<br />
There has been some speculation that use of 2.4Ghz bandwidth introduces significant interferance. Such claims have been refuted by a paper released by ZigBee alliance.[6]<br />
<br />
<br />
== Market ==<br />
<br />
With the WSN market grow to estimated $4.6 billion in 2011, up from $500 million in 2007; ZigBee is a strong contender to become the standard for WSN. Companies can adopt this protocol into its products in an attempt to gain the market share. Also, industrials plants can gain the benefits from better monitoring and control of process, thanks to the lost cost and easy of deployment of wireless sensor networks based on ZigBee. <br />

'''ZigBee''', is a wireless open standard and a competing protocol to Bluetooth, which fall under wireless personal area network (WPAN) classification. It is a standard for mesh networking, with allows for self configuring networks, ease of installation and configuration. It is designed for low power applications, especially applications that are designed for very long batter life. It has a low data rate of 20-250Kbps, depending on the band. The protocol is designed with security in mind.<br />
<br />
<br />
ZigBee is defined and promoted by the ZigBee Alliance, a group of over 150 companies. The current push is for industrial plants where low cost and long battery life remote sensors are required for process control and preventative machine maintenance.<br />

'''ZigBee Target Markets''' [2]]]<br />
<br />
It is intended to be used for home entertainment and monitoring sensors, mobile services such as m-payment and m-healthcare, commercial building monitoring such as HVAC and access control. <br />
For manufacturing the current application is for low power, low data rate wireless sensor networks (WSN).<br />
<br />
<br />
== Technical Information ==<br />
<br />
ZigBee is based on radio frequency (RF) technology and mesh networking.<br />
It is a suite of protocols that covers from the Physical layer, Network layer to the Application layer. The physical layer is an implementation of IEEE 802.15.4 (Bluetooth is covered under IEEE 802.15.1).<br />
<br />
=== Standards ===<br />
<br />

'''802 Wireless Standards Family'''<br />
<br>Zigbee is designed to operate near other wireless standards. [2]]]<br />
<br />
ZigBee implments the IEEE 802.15.4 WPAN standard, which specifies the media-access control (MAC) and physical-layer. This ensures interoperability with other stand-compliant products. This standard specifies operation in the unlicensed bands:<br />
* 2.4 GHz for global use<br />
* 915 MHz for N. America, Australia, and a few other counties<br />
* 868 MHz for EU countries [2]<br />
<br />
ZigBee specification is defined and promoted by ZigBee Alliance. The alliance is an independent, vendor-neutral and non-profit corporation founded in 2002. [2] Adopters of ZigBee technology must licence the technology by becoming members of the alliance. Manufactures must apply for ZigBee certification, which is meant satisfy and minimum conformance to ZigBee standard. This in indented to promote device interoperability, and repuation of ZigBee standard. <br />
<br />
The actual specification is available for non-profit use. The brief history of the specification is:<br />
<br />
* The ZigBee specifications were ratified on 14 December 2004.<br />
* The ZigBee Alliance announces public availability of Specification 1.0 on 13 June 2005, known as ZigBee 2004 Specification.<br />
* The ZigBee Alliance announces the completion and immediate member availability of the enhanced version of the ZigBee Standard in September 2006, known as ZigBee 2006 Specification.<br />
* During the last quarter of 2007, ZigBee PRO, the enhanced ZigBee specification was finalized. [7]<br />

=== Protocol ===<br />
<br />
<br />
[[Image:Zigbee_stack.gif |thumb|300px|right|<br />
'''Simplified ZigBee protocol stack''' [4]]]<br />
<br />
ZigBee standard provides network and application layer. The network layer deals with security management, message broker, routing information and general network management. The security is done at both network and application level, using AES-128 symmetric keys for authentication and encryption. [2] Since it is defined in the specification, all ZigBee products will provide as minimum, which allows for a very secure environment. Developers can provide more security features at the application level. <br />
<br />
<br />
<br />
<br />
=== Interoperability ===<br />
<br />
Zigbee is designed to operate near other devices. ZigBee falls within the 802 family of standards, which includes Wi-Fi and Bluetooth. <br />
<br />
There has been some speculation that use of 2.4Ghz bandwidth introduces significant interferance. Such claims have been refuted by a paper released by ZigBee alliance.[6]<br />
<br />
<br />
== Market ==<br />
<br />
With the WSN market grow to estimated $4.6 billion in 2011, up from $500 million in 2007; ZigBee is a strong contender to become the standard for WSN. Companies can adopt this protocol into its products in an attempt to gain the market share. Also, industrials plants can gain the benefits from better monitoring and control of process, thanks to the lost cost and easy of deployment of wireless sensor networks based on ZigBee. <br />

It is designed for low power applications, especially applications that are designed for very long batter life. It has a low data rate of 20-250Kbps, depending on the band. The protocol is designed with security in mind.<br />
<br />
ZigBee is defined and promoted by the ZigBee Alliance, a group of over 150 companies. The current push is for industrial plants where low cost and long battery life remote sensors are required for process control and preventative machine maintenance.<br />
<br />
== Uses ==<br />
It is intended to be used for home entertainment and monitoring sensors, mobile services such as m-payment and m-healthcare, commercial building monitoring such as HVAC and access control. <br />
<br />
The current application is for low power, low data rate wireless sensor networks (WSN).<br />
<br />
<br />
== Technical Information ==<br />
<br />
<br />
ZigBee is based on radio frequency (RF) technology and mesh networking.<br />
It is a suite of protocols that covers from the Physical layer, Network layer to the Application layer. The physical layer is an implementation of IEEE 802.15.4 (Bluetooth is covered under IEEE 802.15.1).<br />

<br />
With the WSN market grow to estimated $4.6 billion in 2011, up from $500 million in 2007; ZigBee is a strong contender to become the standard for WSN. Companies can adopt this protocol into its products in an attempt to gain the market share. Also, industrials plants can gain the benefits from better monitoring and control of process, thanks to the lost cost and easy of deployment of wireless sensor networks based on ZigBee. <br />
