Comparison Among WiFi, Zigbee and Bluetooth

Lifud new products for wireless contol are coming!

When it comes to the wireless intelligent dimming solutions, Zigbee, Bluetooth and Wifi are the most common options. Do you know the difference among them? How to use them under different scenes? Read the following text to get the answers!


The comparison between the performance of three wireless solutions



Zigbee - low speed, low power consumption, low cost, generally for large area


Zigbee is internationally accepted two-way wireless communication technology. Basically, each of its network port can access more than 65000 ports. It is mainly used for data transmission of various electronic devices that have short distance, low power consumption and low transmission rate, and it can be embedded in a multitude of devices. It is applied in household, industry, agriculture, education, medical and many other fields. Currently, it is the most mature wireless technology to be used and occupies the main market of foreign wireless technology. Amazon Echo is a remarkable example.



Lifud Zigbee solutions


①For intelligent classroom: Zigbee LED driver GSZ series, gateway, light sensor, mechanical & LCD panel, curtain motor, etc.


②For other applications: except the constant current dimming CCT series, constant current dimming series, constant voltage dimming series and constant voltage dimming CCT series will be on markets soon.


Bluetooth - Low cost, direct smart-phone connection, generally for small area



Bluetooth has many options for connection, including point-to-point, broadcast and Mesh networking. Bluetooth Mesh, represented by Tmall Genie ecological chain, is integrated into a large number of consumer electronic products, especially mobile phones, enabling Bluetooth to provide a wider range of interoperability technologies for multiple brands. For example, each intelligent home hardware in bluetooth Mesh network can be connected to each other and send instructions for control linkage, which is the wireless technology closest to the characteristics of the Internet of Things.



Moreover, Bluetooth technology has been developing rapidly in recent years, such as the latest BLE 5.0 Mesh networking:

Transmission rate up to 2Mbps;

Effective working distance up to 300 meters;

Combined with Wi-Fi, indoor positioning with accuracy (<1m) can be achieved.

Lower power consumption and compatible with older versions


At present, Bluetooth dimming products are mainly used in the field of intelligent home, and also have good application effect in the small space indoor commercial lighting.


Lifud Bluetooth 5.0 solutions


The family of Lifud Bluetooth series have constant current dimming series (8-40W), constant current dimming CCT series (12-50W), constant voltage dimming series 150W, constant voltage dimming CCT 150W. There are 4 categories of 12 models nearly 100 standard parameters to meet the needs of different light fixtures.


Wifi - fast transmission speed, high efficiency, generally for the big data transmission of single-product device


At present, Wi-Fi is basically an indispensable device for every family. With its features of instant access to wireless signals, strong mobility, fast data transmission speed and high efficiency, users can have an excellent experience. But the shortcomings are also very obvious - high power consumption, less accessible node number and relatively poor confidentiality and security, limiting Wifi technology to be applied in the large field. Normally, it is used by a small number of intelligent devices that can be plugged into electricity (eliminating the power consumption of Wifi) for large data transmission, seldom used in the illumination dimming control.




1. Currently, Zigbee has a very mature system and application field, which is the most suitable one for low-speed transmission in wireless and suitable to be applied as the main network in the large-scale industry, agriculture, education and home that have a large number of control nodes. 


2. Bluetooth (a compromise between Zigbee and Wifi in terms of performance and cost) is gradually expanding its market share along the early development path of Zigbee. At present, its feature of direct connection with smart phones has a great advantage in small space home, commercial, office and other indoor lighting.


3. With its wide coverage and high transmission rate, it is recommended to be used for a small number of single-product intelligent devices that need real-time big data transmission to improve user experience.
