Bluetooth and Zigbee used to send and receive data wirelessly using radio signals.
Following are the important differences between Bluetooth and Zigbee.
|1||Frequency||Bluetooth frequency ranges between 2.4 GHz to 2.483 GHz.||Zigbee frequency range is mostly 2.4 GHz.|
|2||RF Channel||Bluetooth has 79 RF Channels.||Zigbee has 16 RF Channels.|
|3||Modulation Technique||Bluetooth uses GFSK modulation technique.||Zigbee uses GFSK, BPSK and QPSK modulation techniques.|
|4||Cell Nodes||Bluetooth has maximum 8 cell nodes.||Zigbee also has more than 65000 cell nodes.|
|5||Bandwidth||Bluetooth needs low bandwidth.||Zigbee needs low bandwidth but higher than Bluetooth.|
|6||IEEE||Bluetooth follows IEEE 802.15.1.||Zigbee follows IEEE 802.15.4.|
|7||Coverage||Bluetooth radio signal range is upto 10 meters.||Zigbee radio signal range is upto 100 meters.|
