If dozens of devices need to be connected with Wi-Fi, exceeding the processor load of the router, it is very likely that the entire Wi-Fi network will be paralyzed.
In terms of the number of devices accessed, the Wi-Fi is also very limited. The first is its large power consumption, which is about 1W when standby, while the power consumption of B ZigBee and Bluetooth is only 0.1W. Moreover, the built-in network protocols in mobile phones are adapted to Wi-Fi, so products that choose to use Wi-Fi protocol can easily connect with mobile phones without the need for gateways as intermediate bridges.Īlthough it is easy to use, Wi-Fi still has some shortcomings. It has fast data transmission speed and high efficiency, and users have a very good experience. Nowadays, Wi-Fi has basically become a necessary device for every household. If we only buy the products and lack the gateways, we will not be able to control the products with mobile phones, and we will not be able to realize the intelligent functions of the products. However, most of the smart home products sold using ZigBee protocol do not bring their own gateways.
With its help, in theory, the network node of ZigBee can reach 65000, which can fully meet the needs of our daily life. Generally speaking, the task of this central node is undertaken by the gateway we are familiar with. This central node not only acts as a bridge to transport data, but also manages the entire ZigBee network. Because this communication mode plays a vital role in the colony, ZigBee has become the final name of this short-distance, low-power wireless communication protocol.Īmong them, the biggest advantage of ZigBee protocol is that it can automatically form a device network, and then link the direct data of each device through the central node. In the colony, we can think of this eight-character dance (Zig) as their main communication network. The ZigBee protocol, also known as the Zifeng protocol, is named after bees transmit information through "eight-character dance" after discovering flowers.
