Wireless networks are divided into the following classes:
- Cellular networks WWAN (Wireless Wide Area Network);
- Wireless LAN (WLAN - Wireless LAN);
- Wireless sensor networks (WSN).
In industrial automation, three types of wireless networks are most widely used: Bluetooth based on the standard IEEE 802.15.1, ZigBee based on IEEE 802.15.4 [IEEE] and Wi-Fi based on IEEE 802.11. The physical layers of the OSI model for these networks are based on the corresponding IEEE standards, and the upper layers protocols are developed and supported by Bluetooth, ZigBee and Wi-Fi, respectively. Therefore, the names of networks usually indicate references to the standard. All three networks use an unlicensed ISM (Industrial, Scientific, and Medical) band of 2.4 GHz.
