When designing a smart home system solution, a critical point is the networking mode. The networking mode is related to the stability, scalability, and real-time performance of the entire Smart Home System. In terms of installation and maintenance, I think no one will build a wired smart home network now ......

Therefore, we have no doubt selected a wireless networking method!

There are many wireless networking methods, including Zigbee, Wifi, Z-wave, etc. Of course, a complete smart home system cannot only use a pure Wireless Communication Method for networking, it is often used in combination.

Due to space limitations, this article will only explain the networking applications of one wireless communication wifi in smart home. Wifi is radiating our things every day. I believe everyone is familiar with it! Of course, WIFI is a type of electromagnetic radiation, and it is now recognized that WIFI radiation is harmless ......

Wi-Fi uses a star network topology, and an important feature is that it can transmit video streams with a large amount of data. Therefore, the following is a simple networking:

1. First, computers, tablets, and mobile phones all come with WIFI modules, so they communicate with smart routers through wifi.

2. For a TV, if the TV is playing a network TV or a network video, wifi is required. In particular, most of the current TVs are equipped with WIFI functions or USB interfaces, which can be connected to storage devices such as USB disks or WIFI modules with USB interfaces.

3. Online Video is required for access control video intercom, that is, when someone rings the doorbell in front of your house, surveillance cameras outside the door will transmit real-time surveillance videos to the access control video intercom terminal at home, and the video stream transmission requires WIFI or wired network.

What we need to do next is how to connect the devices to a smart router after we determine which household devices should use WIFI.

For devices with a display interface, such as mobile phones and computers, you can connect to a smart router through wireless settings, but what about devices without an operation display interface? In fact, this is also a solution. The wifi alliance has launched a new technology called WPS (WiFi Protected Setup), which requires support from routers. When we need to connect a device without an operation interface to the network, we only need to press the WPS button on the router and then press the connection button on the device to achieve the connection, of course, if you press the connection button on the device, you need developers to implement it. There are many implementation methods. In this chapter, we will not provide a detailed explanation. The subsequent chapters will be analyzed in detail.

However, WPS technology has security risks and is easy to crack. Later, Texas Instrument (TI) launched a more advanced WIFI connection technology based on WPS, called SimpleLinks. This technology requires the use of software on mobile phones to connect WIFI devices to routers, this technology solves the security risks of WPS in a certain program.

 

The following sections will analyze the technical principles of WIFI!

What is Wireless wifi smart home? How can I control wireless wi-fi smart home use? Why?

[What is Wireless wifi smart home ?]
WIFI wireless Smart Home
WIFI wireless smart home can be said to be the backbone of the Smart Home System.
When wired Smart Home is gradually eliminated by the market due to tedious wiring, difficulty in promotion, and high costs, wireless smart home systems focus more on simplicity and ease of maintenance. Smart Home features are also available, but the control mode is changed from wired to wireless. It is different from some wireless control terminals in wired systems. It completely uses wireless connections between control and does not need to be switched, it can realize comprehensive and intelligent control from the simplest controller to the switch of a lamp to the complex home lighting, curtains, air conditioners, access control, and electrical equipment.

[How to Use Wireless wifi smart home, how to control it ?]

Hardware devices must support the DLNA function !!! Lan supported !!! The most common {Remote Control} is your mobile phone that supports the DLNA function !!
