WHAT IS ZIGBEE
Zig bee is a ad-hoc networking technology for LR-WPAN
It provides a high data throughput in applications
where the duty cycle is low
ZIGBEE CHARACTERISTICS
Intended for 2.45GHZ , 868MHZ and 915Mhz band
Data rates touch 250kbps , 40kbps and 20kbps
Low cost , power consumption as compared to
competing technologies
