WiFi 802.11 wireless Ethernet data communication
IEEE 802.11 or WiFi includes a set of standards for wireless Ethernet networks or wireless LAN. The current 802.11 family includes 6 wireless modulation techniques that all use the same protocol. The currently most popular techniques are described in the a, b, g, h, n-extensions on the original stand. 802.11b, the first standard, was used by a wide audience, followed by 802.11a, 802.11g and 802.11n.
The 2.4 GHz band, 13 channels in the 802.11b / g and 7 channels in the 802.11n standard.
The 5GHz to 5,750GHz band uses 19 channels in 802.11a / h and 11 channels in the 802.11n standard.
These are frequencies are free of license.
The MIMO (Multiple Input Multiple Output) technology, clever uses different channels to obtain a higher data rate and a stable network.
With the MESH technology, it is possible to realize meshed networks.

WiFi products in combination with Ethernet or RS232, RS485 or RS422.
WiFi data communication is used for wireless transmission of Ethernet, RS232, RS422 or RS485 signals. The various types are designed for light industrial to automotive and railway applications where a greater operating temperature range and resistant to shock and vibration is important. The different modules are suitable for DIN rail or wall mounting.
