ISA100.11a is a wireless networking technology standard developed by the International Society of Automation. The official description is "Wireless Systems for Industrial Automation: Process Control and Related Applications". The ISA100 committee is part of ISA and was formed in 2005 to establish standards and related information that will define procedures for implementing wireless systems in the automation and control environment with a focus on the field level. The committee is made up of over 400 automation professionals from nearly 250 companies worldwide. The committee also represents end users, wireless suppliers, system integrators, research firms, consultants, government agencies, and industry consortia. Committee members lend their expertise to the advancement of the ISA100 series of standards. In 2009, the ISA Automation Standards Compliance Institute established the ISA100 Wireless Compliance Institute. The ISA100 Wireless Compliance Institute owns the 'ISA100 Compliant' certification scheme which provides independent testing of ISA100 based products to ensure that they conform to the ISA100 standard.
