While Wifi and Bluetooth are great for certain things, there are better options for some things. Regarding wireless communication for small devices, Zigbee technology is a standard Internet of things (IoT) network that provides a reliable, low-power solution.

Internet of Things (IoT)

IoT is defined as a simple network in which data is exchanged. In simple words, as the name applies, specific essential data needed to switch from one computer to another is exchanged so that it can be uploaded to the internet. The same data can be collected through other techniques, but this technology, known as ZigBee technology, is specially invented for it.

ZigBee Technology transfers simple data, just like data received from sensors. Zigbee technology cab maintains a low data rate of about 250 kbps. The operating frequencies are 868 MHz, 902 to 928 MHz, and 2.4 GHz. ZigBee technology is mainly applied for applications that need low power, low cost, low-rated data, and a much longer battery.

Note: This general comparison table may not apply to all types of Zigbee devices.



The Zigbee coordinator is the most capable device, and it is one of those devices which starts the network. It is responsible for performing many tasks, including selecting the best channel for communication, allocating a unique address to each device, and initiating and transferring messages inside the network. The coordinator is the device that initiates the formation of the network, and there is only one coordinator device in each network.



Routers act as intermediate nodes between the coordinator and end devices. They are responsible for routing traffic between nodes and receiving and storing messages intended for children. Routers can also allow other routers and end devices to join the network. With their capability to store messages, routers can help reduce the traffic between devices and overall network congestion.

End Devices:

End Devices

End devices contain just enough information to talk to the parent node. They can also sleep, which is a better option for saving the battery of devices. All traffic to an end device is first routed to its parent node, which sends the messages to the end device. End devices have low power consumption and are primarily used for transmitting data to the coordinator or routers.

Zigbee technology devices are designed for low-power, low-data rate, and short-range communication. The operating frequency of Zigbee devices is 2.4 GHz, 868 MHz, and 902 to 928 MHz. The range of Zigbee devices can quickly go up to 75 to 100 meters indoors and up to 300 meters or more in outdoor environments. The devices can operate for several years with a single power supply, and they are designed to work with low data rates of 20kbs-250kbs, which is sufficient for short-range communications. Zigbee devices can support up to 65000 devices in a single system, which is much better than other technologies such as Wi-Fi and Bluetooth. With its low-cost products and cheap implementation, Zigbee technology has become a go-to choice for many manufacturers.

Types of Zigbee Technology Network Topologies:

Zigbee consists of different topologies, but only a few are used and correctly configured. The most commonly used configurations are mesh, star topology, and tree topologies. In this article, we will explore the three types of network topologies that Zigbee supports.

Star Topology:

Star topology is the most straightforward and less expensive implementation. In this architecture, there are no routers, and end devices cannot directly communicate with other end devices. The coordinating device is the only point of communication between end devices. One of the drawbacks of this topology is that if the coordinating device fails, the entire network fails. It should be noted that the range is very limited to the scope of the coordinating device itself. This topology is commonly used in health monitoring systems.

Mesh Topology:

In a mesh topology, every node is connected with neighbouring nodes (except for the end devices). A message hops from one device to another to reach its destination. If a node fails, data can be re-routed, and another best path can be chosen. This self-healing process is one of the advantages of mesh topology. Mesh topology is commonly used in home automation systems.

Tree Topology:

Tree topology is not so different from other mesh topologies, but routers are not interconnected, as shown in the figure. It is known as a cluster tree network because it can expand the network range. This topology is commonly used in building automation systems.

The Advantages and Disadvantages of Zigbee Technology:

Zigbee technology has several advantages over other wireless communication technologies, including low power consumption, low cost, and a high level of security. Zigbee’s self-healing feature is also a significant advantage, as it ensures that the network is always available even if some nodes fail.

However, Zigbee also has some disadvantages. For example, the range of Zigbee devices is limited to a few hundred meters, which may be a problem in more significant buildings. Another disadvantage is that Zigbee networks can be slow, and transmitting data between devices may take a while.

Zigbee Technology: How Devices Communicate with Each Other?

Zigbee technology is a wireless communication protocol primarily used for home automation, industrial control systems, and medical device communication. It uses low-power wireless communication and operates on the IEEE 802.15.4 standard.

But how do devices communicate with each other in a Zigbee network? Let’s find out!

Channel Access Methods: Contention-Based and Contention-Free

The Coordinator is the primary device in the Zigbee network, which is responsible for allocating channels to other devices. There are two methods for channel access in Zigbee technology: The contention-based method and the Contention-free method.

Contention-Free Method: Guaranteed Time Slots

Example of Mesh topology

In the contention-free method, the Coordinator dedicates a specific time slot to each device in the network. This is called guaranteed time slots (GTS). The Coordinator ensures that all devices in the network are synchronized by transmitting a message called a Beacon. Once a device receives the Beacon, it adjusts automatically with the Coordinator clock.

Every device waits for its turn to assign and transfer data. Devices not scheduled to share data in a specific time slot will go to sleep mode and wake up only to share data or listen to the Beacon.

Sending Beacon
Waiting for its turn
Waiting for its turn

Example of Mesh Topology

Sleep Mode

In a Mesh topology, one signal is sent to five devices, including the Coordinator device, to assign the GTS correctly. Devices like end devices will go to sleep mode and only wake up to share data or listen to the Beacon.

Contention-Based Method: Carrier Sense Multiple Access

In the contention-based method, devices do not need to be synchronized. They use a carrier sense multiple access with a collision-avoidance mechanism to detect the channel’s clarity before transmitting data. If the channel is busy, the device waits until it is clear to transmit data.

The Zigbee network also uses a self-healing process. If a node fails, data can be re-routed to choose another best path.

Zigbee Technology: An Overview of Its Architecture

Zigbee Technology is a wireless communication protocol designed for low-power, low-cost wireless devices with long battery life and reliable data transfer. It is widely used in the Internet of Things (IoT) and smart home automation. In this article, we will explore the architecture of Zigbee Technology and its various layers.

Physical Layer: The Foundation

The Physical Layer is the lowest in the Zigbee Technology protocol stack. It controls and activates the radio transceiver, selects the frequency, and monitors the channel. It uses packets for communication data, and each packet consists of a Synchronization Header (SHR), a Physical Header (PHR), and a Physical (PHY) payload. The SHR receives synchronization, the PHR contains data about the frame length, and the PHY payload carries data or commands from the upper layers.

MAC Layer: The Coordinator

The Medium Access Control (MAC) Layer is positioned between the Physical and Network layers. It is responsible for generating Beacons and synchronizing devices in the Beacon-enabled Network. The MAC frame can be a Beacon Frame, Data Frame, Acknowledge Frame, or Command Frame. It comprises a MAC Header, a Variable-length MAC Payload, and a MAC Footer. The MAC Header includes security and addressing information, the MAC Payload contains data or commands, and the MAC Footer carries a 16-bit Frame check sequence for data confirmation.

Network Layer: The Builder

The Network Layer combines the Application layer with the MAC layer. It is responsible for maintaining network configuration and routing. It builds a new network and chooses the network topology. The Network (NWK) frame consists of the Header and Payload. The Header contains network-level addressing and control data, while the NWK Payload contains the Application sub-layer frame.

Application Support Sub Layer: The Assistant

The Application Support Sub Layer implements a set of services through two entities – The application Support Data Entity and the Application Support Management Entity – to the application and network layers. These entities are accessed through their respective Service Access Points (SAP).

Application Layer: The User

The Application Layer is the highest and most used Zigbee Technology protocol stack. It hosts the application that holds user applications and Zigbee device objects. Each device contains up to 240 applications that control and manage the protocol layer. The application objects consist of one profile or program generated by the user or the Zigbee Alliance. This application is responsible for data transmission. The application profile defines each device’s type and function—the Zigbee Device Objects interface between application objects, device profiles, and the Application sub-layer.
