How to use WIFI network smart home? What are the smart home wireless communication technologies?

The concept of smart home is obviously convenient. Through the Internet connection, all devices are connected together. At the same time, remote control through intelligent mobile phones, enabling rules, and automated experience can be achieved. Of course, all this is based on connections, so the performance of the home network connection is crucial. So, how to make WIFI network better serve smart home products? What are the smart home wireless communication technologies?

How to use WIFI network smart home?

5GHz band may cause problems

The current popular 802.11ac wireless routers have 2.4 GHz and 5 GHz frequency bands, and the latter has relatively faster connection rates and less interference. However, not all smart home devices are compatible with the 5GHz band, so if you are using an older router in your home, you should pay attention to the 2.4GHz model when purchasing smart home devices.

When the device cannot identify the network: Restart first

This is a very easy to understand operation. If the smart home device cannot connect to the WIFI network, restarting the device and the router all at once and then setting up will usually solve the problem.

SSID and security settings

There is no doubt that you need to set the SSID broadcast name and password for the wireless router. Otherwise, not only the router may be connected to other people, but smart home devices are also very easy to be invaded. As for the encrypted form, WPA2 is currently the most suitable for smart devices.

reset

If the smart home device does not work and you have already tried to restart it, you can restore the factory settings to determine whether it is a system problem or a hardware problem. In addition, if vendors release new firmware, they will usually improve connection stability and security, and timely upgrade is also necessary.

What are the major wireless communication technologies in smart homes?

1 Infrared communication technology;

Radio frequency technologies such as 2433 MHz and less than 1 GHz;

3 Bluetooth technology;

4ZigBee communication technology;

5Z-Wave technology;

6WiFi technology.

Each technology has its own advantages and disadvantages, but no matter which communication technology is used, if you want to achieve remote control of home devices, the devices need to access the Internet. WiFi communication technology is a mainstream technology for handheld terminals accessing the Internet. Devices that use other communication technologies than WiFi technology require a home gateway to switch to the Internet. For example, a smart home system using ZigBee technology needs to be used in a home gateway. Increase ZigBee to WiFi functionality.

The main advantages of WiFi technology in smart home applications are: WiFi smart nodes can be directly connected to wireless routers to access the Internet; no home gateway is required, nodes can be arbitrarily expanded; existing installations will not be destroyed; smart phones can be used for local area networks. Control and remote control.

Of course, WiFi technology has its disadvantages compared to ZigBee and 433 MHz radio frequency communication technology: high power consumption and high price. However, with the introduction of energy-saving technologies and improvements in chip technology, power consumption issues and price issues have been gradually resolved. Since the WiFi module is a standard configuration of notebooks, tablet computers, and smart phones, the smart home based on the WiFi technology will be gradually promoted and applied, and the market prospect is broad.
