Take you to know the smart home Zigbee 3.0 protocol

In today's smart homes, a large part of smart devices use the Zigbee protocol as the communication network of the device, and Zigbee 3.0 has become one of the suitable network adaptation protocols in smart homes with its unparalleled compatibility.
 

Why is Zigbee 3.0 the right protocol?

This is the origin of Zigbee.

The beginning of Zigbee was born to equip the Industrial Internet of Things with a network communication protocol, and Zigbee came forward to set off this banner, but because the Industrial Internet of Things requires completely different application scenarios, the Zigbee Alliance targets different applications. The scenario, launched a different Zigbee protocol, so the previous Zigbee protocol has a very large number of categories:

Zigbee Home Automation (Zigbee HA), Zigbee Light Link (Zigbee LL), Zigbee Building Automation (Zigbee BA), Zigbee Retail Services (Zigbee RS), Zigbee Health Care (Zigbee HC), Zigbee Telecommunication services (Zigbee TS).

Although different Zigbee protocols correspond to different application scenarios, these Zigbee protocols cannot communicate with each other. In other words, if I use the Zigbee HA protocol switch, it is impossible to control the Zigbee LL protocol light bulb, which not only increases the threshold for users to use the Zigbee smart home system, but also cannot use a smart device that cannot communicate to form a complete smart. Home.

Of course, the Zigbee Alliance is aware of this, and then launched the Zigbee HA1.2 version for the above shortcomings, but Zigbee HA1.2 also has some limitations, unable to unify all Zigbee application scenarios into a complete home system. So Zigbee 3.0 came into being.

Zigbee 3.0 uniformity

Zigbee 3.0 defines more than 130 devices covering a wide range of device types, including not only common home automation, home lighting, smart appliances, but also sensors and healthcare monitoring products.

Even ZigBee 3.0 is supported and included in all types, commands, and features based on ZigBee PRO.

Standardized network layer

Zigbee 3.0 is based on the IEEE 802.15.4 standard, using the global 2.4 GHz frequency, and Zigbee 3.0 uses the Zigbee PRO standard network layer protocol. Even small, low-power devices can achieve reliable and stable communication linkage. .

Zigbee 3.0 is more stable and reliable. Zigbee 3.0 uses a multi-hop mesh network to effectively eliminate the impact of single-point failures. It also expands the coverage of the network and makes the device communicate farther.

Zigbee 3.0 consumes less power, and Zigbee 3.0 allows battery-powered smart devices to be used for extended periods of time, up to seven years in a row. It also supports Green Power's smart devices, which can be used even without a battery.

Zigbee 3.0 is highly scalable and provides a network that supports thousands of nodes for smart homes or smart cities.

Zigbee 3.0 is globally versatile. Zigbee 3.0 is based on the 2.4 GHZ band and can be used anywhere in the world without an additional license agreement.

Zigbee 3.0 not only unifies Zigbee's application layer protocols, but Zigbee 3.0 also brings more powerful features such as the new Green Power and wider compatibility. These new features ensure Zigbee 3.0's extraordinary status.

The meaning of Zigbee3.0

The standardization of Zigbee communication protocol is of great significance. If you continue to fight against different application layer protocols in the past, each company has its own unique technology and standards, but the wireless communication templates cannot be linked together, let alone The whole house smart home is interconnected.

The significance of Zigbee 3.0 is here, establishing a communication connection network between different devices, so that all smart home products can be unified into the same network, making the home experience more intelligent and convenient.
