Smart home and other areas of the Internet of Things WiFi module selection what is worth noting?

1. Define the application of the wifi module and the data transmission function that needs to be implemented. The amount of data determines the data throughput of the selected wifi module.

2. Define which interfaces the device needs to provide to achieve the required WiFi data transfer function and select the WiFi module with the corresponding interface based on the interfaces the device can provide.

In addition, in the process of data transmission, wireless modules companies is the master device or from the device; specific functional requirements; whether the need for a special interface WiFi module;

3, consider the selected WiFi module design itself several key indicators

a: WiFi module's transmit signal power, in different wireless protocols, the transmission power is different.

b: Transmission rate of the wifi module

Depending on the protocol and the hardware configuration of the module itself, the transmission rate of the WiFi module will vary.

c: WiFi module transmission security distance, WiFi module transmission distance, needless to say, nearly half of the WiFi module requirements will consider this factor.

d: WiFi module power consumption

In the definition, the difference between the input power and output power of a device, equipment, etc. The power consumption of a wireless module is closely related to the transmit power and the transmission distance of the wireless module. The higher the transmission power, the greater the transmission distance, and the greater the power consumption.

5. WiFi module reception sensitivity.

Receiving sensitivity is an important parameter to characterize the technical performance of the object to be tested, the better the receiving sensitivity, the more useful information signals it receives, the greater the impact of its wireless network coverage nationwide.
