Wi-Fi module for internet of things

- Aug 08, 2019-

Introduction to Wi-Fi module:
Wi-Fi module, also known as serial Wi-Fi module, belongs to the Internet of Things transmission layer. 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. The traditional hardware device embedded in the Wi-Fi module can directly use Wi-Fi to connect to the Internet, and is an important part of implementing Internet of Things applications such as wireless smart home and M2M.

Wi-Fi module application areas:
Wi-Fi Module is used in serial to Wi-Fi, TTL to Wi-Fi, WiFi monitoring, Wi-Fi remote control aircraft and other toy fields, WiFi network radio, digital photo frame, medical equipment, data acquisition, smart card terminal; home intelligence, instrumentation, wireless POS Other wireless related secondary development applications such as modern agriculture and military fields.

The main functions of the Wi-Fi module:
The Wi-Fi module includes two types of topological forms: the basic network and the ad hoc network. To explain the topology of the wireless network, first understand two basic concepts: 1: AP, which is the wireless access point, which is a The creator of the wireless network is the central node of the network. The wireless router used in a typical home or office is an AP. 2: STA sites, each connected to a wireless network terminal, like a laptop and other user devices that can be networked, can be called a site.
