Glossary SCADA / Term
IEEE 802.11 (wireless Ethernet) is a family of standards for wireless LANs.
| Protocol | Release Date | Operating Frequency | Typical Data Rate | Maximum Data Rate | Indoor Range |
| IEEE 802.11a | 1999 | 5 GHz | 23 Mbps | 54 Mbps | 35M (115 ft) |
| IEEE 802.11b | 1999 | 2.4 GHz | 4.3 Mbps | 11 Mbps | 38M (125 ft) |
| IEEE 802.11g | 2003 | 2.4 GHz | 19 Mbps | 54 Mbps | 38M (125 ft) |
| IEEE 802.11n | Not released | 5 or 2.4 GHz | 74 Mbps | 540 Mbps | 70M (230 ft) |
| IEEE 802.11y | Not released | 3.7 GHz | 23 Mbps | 54 Mbps | 50M (164 ft) |
IEEE 802.11 enables users to establish a secure connection (including Authentication and Encryption) between the data source and destination. The number of companies that use IEEE 802.11 is quickly growing as cybersecurity issues associated with wireless communication are solved.
OPC communication can use Wireless Ethernet for its networking backbone. However, users must take special care to ensure that network reliability and Quality of Service (QoS) remain high, real-time data could be lost.
People often use the terms Wireless Ethernet and Wi-Fi interchangeably. However, this is technically incorrect because Wi-Fi is a brand name that the Wi-Fi Alliance owns.
