Smart Home Zigbee version 3
Why do we need to use the smart home Zigbee version 3?
In today’s smart home, a large part of smart devices use the Zigbee protocol as the device’s communication network, and Zigbee 3.0 has become the most suitable network adaptation protocol in the current smart home with its unparalleled compatibility.
Why is only smart home Zigbee version 3 the most suitable protocol?
This comes to the origin of Zigbee.
In the beginning, the birth of ZigBee was to equip the industrial Internet of Things with a network communication protocol, and ZigBee came forward to carry this banner, but because the industrial Internet of Things requires completely different application scenarios, the Zigbee Alliance targets different In application scenarios, different Zigbee protocols have been introduced, so the early ZigBee protocols have many 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 there are different Zigbee protocols corresponding to different application scenarios, these Zigbee protocols cannot communicate with each other. In other words, if I use the switch of the Zigbee HA protocol, it is unable to control the bulb of the Zigbee LL protocol, which not only increases the threshold for users to use the Zigbee smart home system but also the use of smart devices that cannot communicate can not form a complete smart home.
Of course, the Zigbee Alliance is also aware of this, and then launched Zigbee HA1.2 version in response to the above shortcomings, but Zigbee HA1.2 also has certain limitations, and it is impossible to unify all Zigbee application scenarios into a complete home system. , So Zigbee 3.0 came into being.
The unity of smart home Zigbee version 3
ZigBee 3.0 defines more than 130 devices, covering the widest range of device types, including not only common home automation, home lighting, smart home appliances, but also sensors and healthcare monitoring products.
Even the types, commands, and functions of all devices defined based on ZigBee PRO are all supported and included in ZigBee 3.0.
Standardized network of smart home ZigBee version 3
Based on the IEEE 802.15.4 standard, Zigbee 3.0 uses the universal 2.4 GHz frequency, and Zigbee 3.0 uses the Zigbee PRO standard network layer protocol. Even the smallest device with the lowest power consumption 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 a single point of failure, and at the same time, it can expand the network coverage and make the device’s communication distance farther.
·Zigbee 3.0 has lower power consumption. Zigbee 3.0 allows battery-powered smart devices to be used continuously for a long time, up to seven years. And it also supports smart devices with green energy Green Power, which can be used normally without even needing a battery.
· Zigbee 3.0 is highly scalable and can provide a network supporting thousands of nodes for smart homes or smart cities.
· Zigbee 3.0 is universal. Zigbee 3.0 is based on the 2.4 GHz frequency band and can be used anywhere in the world without an additional license agreement.
Zigbee 3.0 not only unifies the protocols of each application layer of Zigbee but also brings more powerful functions, such as the new Green Power and wider compatibility. These new features ensure the extraordinary status of ZigBee 3.0.
The greatest significance of smart home ZigBee version 3
The standardization of the ZigBee communication protocol is of great significance. If you continue to fight in accordance with the different application layer protocols in the past, each company has its own set of unique technologies and standards, but the wireless communication templates between them cannot be linked, let alone Smart homes in the whole house are interconnected.
And the greatest significance of ZigBee 3.0 is here, to establish 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.
