[Abstract]:
Introduction about Wi-Fi Module and Antenna Application in the Wi-Fi Module

Difinition

The Wi-Fi module, also known as the serial port Wi-Fi module, belongs to the transmission layer of the Internet of Things. Its function is to convert the serial port or TTL level into an embedded module that conforms to the Wi-Fi wireless network communication standard. The built-in wireless network protocol IEEE802.11b.gn Protocol stack and TCP/IP protocol stack. Traditional hardware devices embedded in Wi-Fi modules can directly use Wi-Fi to connect to the Internet, which is an important part of realizing wireless smart home, M2M and other Internet of Things applications.

 


Main classification
Wi-Fi modules can be divided into three categories: 1. General Wi-Fi modules, such as mobile phones, notebooks, and tablets.
The USB or SDIO interface module on the brain, the Wi-Fi protocol stack and the driver are run in Android, Windows, and IOS systems, which require a very powerful CPU to complete the application; 2. The router solution Wi-Fi module, typical It is a home router. The protocol and driver are based on the chip with powerful Flash and Ram resources plus the Linux operating system; 3. Embedded Wi-Fi module, 32-bit microcontroller, built-in Wi-Fi driver and protocol, and the interface is a general MCU interface such as UART etc. Suitable for all kinds of smart home or smart hardware items.

Many manufacturers have tried to add Wi-Fi modules to TVs, air conditioners and other equipment to build wireless home smart systems. Realize APP control and docking with Internet giants such as Alibaba Cloud, JD Cloud, Baidu Cloud, etc., allowing home appliance manufacturers to quickly and conveniently realize their own products' network intelligence and interconnection with more other appliances.
