The wireless connection technology is the most critical in IoT application, SKYLAB is a wireless module R&D manufacturer. SKYLAB can provide WiFi module, Bluetooth module, GPS module IoT application solutions. In this article I want to tell you how to choose WiFi module for smart home IoT.
WiFi module belongs to the IoT transport layer, built-in wireless network protocol IEEE802.11b.g.n protocol stack as well as TCP/IP protocol stack. It can convert serial port or TTL level to WiFi wireless network communication standard compliant embedded module.
WiFi modules are standard in tablet PCs and smartphones. There are many advantages of WiFi technology in smart home. WiFi smart nodes can be directly connected to wireless routers. Thus, they can access the Internet network. It does not need a home gateway, and the nodes can be expanded at will. Smart phones can be controlled by LAN and remote control.
WiFi modules can be divided into three types: general-purpose WiFi modules, router WiFi modules and embedded modules. Many traditional devices that can be networked are embedded WiFi modules
1、Communication interfaces include USB, WAN/LAN, UART, I2S, I2C, SPI, SD, PWM.
2, power supply 3.3V is more commonly used, there are also 5V power supply.
3, the antenna processing have PCB board and through the Ipex seat external.
4, choose the right module size to facilitate integration.
5、The working frequency band is 2.4-2.5GHz, 5.0-5.8GHz.
6, platform compatibility, some main control MCU will have a fixed wifi chip reference model.
7, the software platform is basically linux and android, there are also some XP2000, Vista or windows.
8, module chip manufacturers are mainly Realtek / MTK / Atheros / Bo, etc.
