Zigbee vs. Thread vs. Matter: What’s The Difference?

Building a smart home is exciting, but navigating technical terms can be overwhelming. When discussing smart devices, you’ll likely encounter terms like Zigbee, Thread, and Matter. These main players in smart home technology make connectivity easier and improve user experience.

While all of them are related to smart home communication, it’s crucial to understand their differences to have a seamless and secure connected experience.

Key Takeaways

  • Thread is more suited for low-power applications and provides speed and reliability. However, it is solely an IPv6-based protocol.
  • Matter is a smart home standard that unifies several different particles, such as Wi-Fi and Thread.
  • Zigbee is similar to Thread but is not directly compatible with Matter. Connecting to Matter requires a separate Bridge, as it operates as a standalone solution with its own application and network layers.

IoT Technologies: Connecting Smart Homes One Device At A Time

IoT technologies have transformed the lives we’ve been accustomed to. These technologies make integrating many smart devices smooth and easy to manage, allowing users to control and automate their smart devices more seamlessly. 

IoT technologies form a smart home ecosystem—from smart door locks, smart hubs, smart cameras, smart sensors, smart lighting, and smart controllers, among others. 

IoT technologies play a leading role in the smart home environment. These technologies allow devices to communicate and share data, leading to a network of connected devices that improves our lives and productivity. 

One important technology that can be considered when talking about smart homes is IoT. For example, you can monitor the temperature inside your house from anywhere, or the alarm system will send you mobile messages.

To comprehend the functions of these technologies, we must have an understanding of the concept of the Open Systems Interconnection (OSI) model. The model was created to sort out the different communication protocols and their generations. 

The OSI model consists of seven layers, and each layer has a function in allowing devices to communicate:

  • The bottom layer is the physical layer, which focuses on the physical transmission of data through media such as wires or electromagnetic waves. 
  • The middle is the Data Link layer, which transports data to the other end of the same network. 
  • The network layer routes the data packets from one network to another. 
  • The transport layer is the second layer, and it is responsible for handling the transmission of data packets from one device to another.
  • The last three layers focus on communication from the point of application. These include the session layer that establishes and controls communication between devices, the presentation layer that converts the data into a format the receiving device can understand, and the application layer that works with the actual data being transmitted.

What happens to Zigbee, Thread, and Matter in this model? Zigbee is a complete protocol that works at the OSI model’s application and network layers. It has its own application and network layers, which makes it an all-stack solution for home automation requirements. 

Thread, however, works only at the network layer and uses the typical IPv6 for communication. Matter, being a standard of communications that works in addition to existing protocols, does not have a particular OSI layer.

What Is Zigbee?

Zigbee is a wireless communication protocol intended to low-power, low-data-rate applications. It operates on the IEEE 802.15.4 standard and it uses the frequency band of 2.4 GHz. Zigbee is known for its power management and along with its mesh network, it is ideal for society, for energy consumption, for the disappearance of energy in the smart locks market.

Key Benefits of Zigbee:

  • Low power consumption, prolonging battery life for connected devices.
  • Mesh networking capability, enabling devices to relay messages and extend coverage.
  • Robust security features, including AES-128 encryption, to protect data transmission.

What Is Thread?

Thread is a mesh networking protocol established by the Thread Group, which is made up of industry leaders such as Google, Apple, Amazon, and others. 

Contrary to Zigbee, Thread works only on IPv6, thereby providing native internet connectivity to smart devices. This allows seamless integration with the already existing IP-based networks, which makes setup and configuration easy.

Key Benefits of Thread:

  • It has low latency and high reliability, which is ideal for real-time applications such as home automation and voice control.
  • Built-in IPv6 support facilitates direct communication with internet services and cloud platforms.
  • Dynamic routing and self-healing capabilities, ensuring robust and resilient network operation.

What Is Matter?

Matter is an interoperability standard introduced by the Connectivity Standards Alliance (CSA), which was earlier called Project CHIP (Connected Home over IP). The objective of Matter is to consolidate the divided smart home ecosystem by creating a universal platform for the communication of devices. 

It differs from Thread and Zigbee because Matter is a smart home standard that incorporates different wireless protocols. It threads together an IP network that enables devices to work together.

Key Benefits of Matter:

  • Universal compatibility across various smart home platforms, ensuring seamless integration and interoperability.
  • Simplified setup and configuration through standardized device profiles and protocols.
  • Enhanced security features, including device attestation and encryption, to protect user data and privacy.
