Embedded WiFi Modules

Wifi modules also called Serial wifi modules, Function is the serial port or TTL level to comply with wifi wireless network communication standard embedded modules, built-in wireless networking protocols 802.11b / g / n protocol stack and TCP / IP protocol stack. Traditional embedded wifi wireless wifi module can directly access the Internet, is an important part of the intelligent home, M2M and other networking applications.

Embedded wifi Module interface and TTL UART serial ports, built-in WIFI drivers and protocols. It includes two types of topologies: basic network (Infra) and ad hoc network (Adhoc). AP based wireless network is based on components, created by the AP, consisting of a number of STA joins the wireless network, which summarizes all communication through AP to forward complete. MANET is composed of only two or more STA own composition, the network does not exist in AP, this type of network is a loose structure, all of the STA in the network can communicate directly.

USR IOT wifi module has been widely used in monitoring, wireless development and application of relevant secondary medical instrumentation, data acquisition, handheld devices, smart card terminals, intelligent home, modern agriculture.
