The Role of Zigbee Technology in Future Data Communication System

 Zigbee is a low power spin off of WiFi

 What is Zigbee
ZigBee is an IEEE 802.15.4 standard for data communications with business and consumer devices. It isdesigned around low-power consumption allowing batteries to essentially last forever. The ZigBee standard provides network, security, and application support services operating on top of the IEEE 802.15.4 MediumAccess Control (MAC) and Physical Layer (PHY) wireless standard. It employs a suite of technologies toenable scalable, self-organizing, self-healing networks that can manage various data traffic patterns.

 

ZigBee is a low-cost, low-power, wireless mesh networking standard. The low cost allows the technology to be widely deployed in wireless control and monitoring applications, the low power-usage allows longer life with smaller batteries, and the mesh networkingprovides high reliability and larger range.ZigBee has been developed to meet the growing demand for capable wireless networking between numerous low-power devices. In industry ZigBee is being used for next generation automated manufacturing, with small transmitters in every device on the floor, allowing for communication between devices to a centralcomputer. This new level of communication permits finely-tuned remote monitoring and manipulation. 
 


this certainly looks like it is going to  change the way networks function, because of its low cost.
ZigBee's low power consumption, built-in security method and ratified specifications make it very suitable to be used with medical sensor devices. Medical sensors in a human body self organize in a ZigBee Personal Area Network (PAN). At a higher level, these PANs are interconnected in a Healthnet. To this end, a ZigBee PAN detects the existence of another PAN with beacon detection or active channel scan and selects proper target based on the peak energy (when energy detection channel scan is used). Different ZigBee interconnection schemes are then possible. PAN bridge method uses special bridge node that works for different PANs with time division method. This looks like it will compete with RFID sensor technology.
