The Web Sensor Gateway Architecture for ZIGBEE Milan Ganesh [1JS07EC054]

What is ZIGBEE? ZigBee is the set of specs built around the IEEE 802.15.4 wireless protocol Intended for 2.45 Ghz , 868 Mhz and 915 Mhz Band. Low in cost ,complexity & power consumption as compared to competing technologies. Intended to network inexpensive devices . Data rates touch 250Kbps for 2.45Ghz ,40 Kbps 915Mhz and 20Kbps for 868Mhz band.

The need for ZigBee Standard in a fragmented market 9/21/2018 The need for ZigBee Standard in a fragmented market Many proprietary solutions, interoperability issues Simple protocol, Global Implementation 2.4GHz Low Power consumption 6 months to more than 5 years battery life for most applications Low Cost High density of nodes per network 250 nodes per network, multiple co-located networks Data rate requirements Few bits to 250kbps sufficient
