BLUETOOTH INTRODUCTION
It is an open wireless for exchanging data over short distances from fixed and devices personal area networks.
First specification in -July 1999.
Devices can be connected to multiple devices at the same time.
This devices are organised into groups , called “PICONETS”
WHAT IS ZIGBEE?
Zigbee is the name of specification for a suit of high level communication protocol.
A very low cost, low power consumption, two-way wireless communication standards for automation.
Technological standards created for controls and sensor networks.
HISTORY OF ZIGBEE
ZigBee network began to concieved about 1998 when many installer realised that both WiFi and Bluetooth were going to unstable for many application.
In summer of 2003 ,philips semiconductor.a major mesh network supporter ,ceased the investment.
The zigBee alliance announced in october 2004 and had grown to more than 100 member companies ,in 22 counteries.
WHAT DOES ZIGBEE DO?
Designed for wireless controls and sensors
Operates in Personal Area Networks (PAN’s) and device-to-device networks
Connectivity between small packet devices
Control of lights, switches, thermostats, appliances, etc.
CONCLUSION
ZigBee's current focus is to define a general-purpose, inexpensive, self- organizing, mesh network that can be used for industrial control, embedded sensing, medical data collection, smoke and intruder warning, building automation, home automation etc.
