Zigbee vs Bluetooth: Difference and Comparison

As technological advances take place, wireless technology becomes more popular among netizens. Without direct or wired connectivity, the transfer of files and data from one device to another requires the development of technology. Hence technology like Bluetooth and Zigbee developed. 

However, these are not competing technologies. In this article, we will discuss both the technologies, their aim, the set of devices and applications they use, their design structure, and finally, how they differ from each other.

Key Takeaways

  1. Zigbee is a low-power, low-data-rate wireless communication standard used for industrial applications.
  2. Bluetooth is a wireless communication standard for short-range communication between smartphones, laptops, and headphones.
  3. Zigbee provides a mesh network architecture, while Bluetooth operates in a point-to-point or point-to-multipoint architecture.

Zigbee vs Bluetooth

Bluetooth is a cordless automation used to connect to other computers and smartphones for data sharing. It requires low-power radio waves. Zigbee is another cordless machinery that assists in connecting personal area networks by using minimal energy and low-power radio waves.

Zigbee puts importance on automation. It uses low power consumption and lower data rates on smaller packet devices. The frequency range of Zigbee is around 2.4GHz. Zigbee has 16 RF channels in total.

The modulation techniques used are BPSK, QPSK, and GFSK. It comprises 6500+ cell nodes. The bandwidth used by it is low, but it’s higher than Bluetooth. The IEEE version followed by Zigbee is 802.15.4.

Bluetooth puts more importance on connectivity near mobile devices. However, it uses higher power consumption and higher data rates on big packet devices. The frequency range of Bluetooth devices varies from 2.4GHz to 2.483GHz.

There are 79 RF channels in the case of Bluetooth. GFSK is the modulation technique used by Bluetooth. It comprises around 8 cell nodes in total. The bandwidth used by Bluetooth is comparatively low. The IEEE version followed by Bluetooth is 802.15.1.

What is Zigbee?

Zigbee is protocol having high-level communication. It is used in the creation of PANs or personal area networks, with the help of small or low-power digital devices such as radios, basically for automation.

It is also used to collect data from medical devices and in case of low bandwidth and power needs. Zigbee is specially designed for such smaller-scale projects which do not need a wired connection but rather a wireless one.

Thus, it can be operated only in the personal area or nearby. That’s why it is characterized by low data rate and power, wireless and hoc networks. Compared to other wireless technologies, Zigbee is much simpler and less expensive.

It is cheaper than Bluetooth and Wi-Fi as well. The applications include traffic management systems, wireless light switches, home energy monitors, and other types of industrial and consumer equipment requiring low-rate and short-range data transfer in a wireless manner.

What is Bluetooth?

Bluetooth is used for the exchange of data between two fixed points. One can be a mobile, and another can be a laptop. The exchange takes place over short distances by the use of UHF radio waves by building PANs or also known as personal area networks.

This wireless technology has a short-range operation and can act as a great alternative to data cables like RS-232.

Special Interest Group has 35,000 member companies that manage Bluetooth. The member companies are spread out in areas of computing, telecommunication, consumer electronics, and many more.

However, managing it also overlooks the development of speciation and protects the trademark as well. Till 2009, the shipment of integrated circuit chips units was 920 million annually. This is approximate and not accurate data.
