Introduction

In the ever-changing world of wireless communication technologies, ZigBee has positioned itself as a principal technology with a focus on IoT and smart homes. In this blog, we will cover all essential and strapping aspects of ZigBee in its application geography and architecture so that you can gain the operational power to employ this technology to the full. 

 What is ZigBee?

 ZigBee is a standards-based wireless technology designed for low-cost, low-rate wireless M2M and communication protocols in IoT applications. They are a low-power wireless mesh network standard designed for battery-operated devices in wireless control, and monitoring applications. ZigBee is characterized by low latency and its chips are usually incorporated with radios and microcontrollers.

 The fundamental attributes that can be considered essential for ZigBee and that contribute to the selection of the technology for different applications include; low power consumption, mesh networking, and low cost. For these reasons, ZigBee has found its way to be used in many embedded systems applications, industrial applications, and home automation systems.

 

ZigBee Structure and Its Hierarchy of Network Types 

 ZigBee networks are built upon a hierarchical architecture, consisting of three primary device types:

 1. Coordinator: Being the key official of the network, the coordinator’s role consists of starting and leading a network. It provides a unique address to all the devices and has routing tables. 

 2. Router: Switches can also be used to connect several devices to a network and can forward the data as routers do. It also can directly communicate and command end devices.

 3. End Devices: Ad end devices are units with data transmission and reception ability but cannot directly forward data to other units. They are generally portable and built to consume minimum power.

 ZigBee networks can be thus built with different topological structures, namely, star, tree, and mesh. The mesh topology is the most beneficial in the process, as all the devices have to be connected, enabling them to communicate and create an FFN, which is self-correcting.

Pros Of Zigbee:

1. Intended to use less power.
2. Operates on top of IEEE and offers services for application support and network security.
3. Zigbee enables fully networked houses where any gadget may interact and be connected.
4. Employ in your smart house
5. Simple to apply
6. Adequate security features.
7. Low cost: Zigbee chips and modules are reasonably priced, making them an affordable option for Internet of Things applications.
8. Mesh networking: Zigbee employs a network topology called mesh, which does not require a hub or router for devices to communicate with one another. Because of this, it is perfect for use in smart home applications where devices must be able to communicate with one another and with a central hub.
9. Reliability: The Zigbee protocol is built with strong safeguards to guarantee that data is delivered consistently even under trying circumstances.

Cons of Zigbee:

1. Restricted range: When compared to other wireless communications protocols, Zigbee’s range is very low, which may make it less appropriate for use in big buildings or for some types of applications.
2. Limited data rate: Zigbee may not be the best choice for applications that need high-speed data transfer because it is intended for low-data-rate applications.
3. Interoperability: Finding devices that are compatible with one another might be challenging because Zigbee is not as commonly used as other IoT protocols.
4. Security: Compared to other IoT protocols, Zigbee has less solid security protections, which makes it more susceptible to hackers and other security threats.

 ZigBee Applications and Use Cases

The versatility of ZigBee technology has led to its adoption across a wide range of industries and applications, including:

 1. Home Automation: There are many applications of ZigBee, including smart home uses in lighting, temperature regulation, safety, and device and appliance control. 

 2. Industrial Automation: Applications of ZigBee are seen in industries as it is used in monitoring, controlling, and even optimizing the operations of processes, machines, and energy. 

 3. Building Automation: ZigBee is used in building management through which the management of HVAC, lighting, and access control are easily controlled. 

 4. Healthcare: Medical and healthcare industries are some of the fields that make use of ZigBee devices like patient monitors, asset tracking, and remote patient monitors. 

 5. Agriculture: The ZigBee networks are utilized in precision agriculture to sense the soil condition, irrigation, and cattle trails. 

 6. Retail and Logistics: ZigBee technology is used in inventory control, asset tracking, and inventory replenishment in the retail and logistics industries. 

 The Evolution of ZigBee: 

ZigBee 3 control protocol connects up to 250 devices to the coordinator device. 0 and ZigBee Direct 

 To meet changing dynamics in the IoT vortex, ZigBee has been revised and updated very often and as such. The appearance of ZigBee 3. 0 and ZigBee Direct stands as the continuing advancements aimed at the improvement of the system and its compatibility. 

 ZigBee 3. 0 is a new and improved specification that integrates the different ZigBee profiles in a bid to cut across the many barriers that are prevalent in products from different manufacturers. Security is also bolstered by providing a superior security protocol to mitigate risks of cyber threats within the organization. 

 In addition, ZigBee Direct integrates BLE in the specification making it possible to onboard and control a device directly from a smartphone without the presence of the hub. This feature is in line with the general shift towards easier-to-use and more natural smart home interfaces. 

 Conclusion 

 Over the years, ZigBee has taken root and is now among the most favorable wireless communication technologies in IoT and smart homes. The small power usage, which supports the use of mesh networking, and price make it attractive.
