Difference between Bluetooth and Zigbee

Bluetooth technology is a wireless device system through which some electronic devices communicate with each other. It has features like a low cost, short range and also has less power consumption while in Zigbee network is a specification set of wireless protocols devices and that have been designed for data transfer by the very low power device. So now let us check it out the difference between Bluetooth and Zigbee to know more details about it.

Definition :
  • Bluetooth: It is wireless technology through with electronics devices which communicated with each other. It can be used for the creation of a personal network that operates in the 2.4 GHz unlicensed band and with a range of 10 meters.
  • Zigbee: While in Zigbee a specification for a set of wireless protocol that has been designed for data transfer by low power devices. It is based on a format IEEE 802.15 standard. 
Origin :

  • Bluetooth: It launches in the year of 1994 by Swedish telecom giant Ericsson. It named after a famous European unification king, Harald blatant.
  • Zigbee: Devised in the year 1998. It named after the movement of a honeybee.
Protocol update :
  • Bluetooth : Updated under version  like 2.0, 2.1, 3.0, 4.0 etc.
  • Zigbee : Zigbee and Zigbee pro.
Management :
