ISA100

Introduction ISA is a wireless technology in the category of the WSN (wireless sensor network). Indeed, it was created for industrial automation and control applications. It’s an open and universal IPv6 wireless network developed by the International Society of Automation (ISA) in 2009. In the committee there were also 250 companies officials to define the characteristics of ISA100. Its official description is: “Wireless Systems for Industrial Automation: Process Control and Related Applications.”

The technology

Based on the IEEE 802.15.4 protocol, ISA100 uses the 2.4 GH frequency band. The data rate is up to 250 kb/s. The exchange of data is done with CSMA/CA LBT (listen before talk) CCA (clear channel assessment). This choice was made to ensure the co-existence with other unmanaged wireless devices using the 2.4 GHz frequency band). Speaking about security, the protocol includes an authentification and encryption (use of a time-enhanced application of the NIST standard 128-bit AES).
