ISA100.11a is an open wireless networking technology standard developed by the International Society of Automation (ISA). 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 also known as the WCI. The ISA100 Wireless Compliance Institute owns the 'ISA100 COMPLIANT' certification scheme and provides independent testing of ISA100 based products to ensure that they conform to the ISA100 standard (www.isa100wci.org).

Nivis launched the world's first ISA100.11a field device stack and gateway which can both be purchased as part of the Nivis development kit.
Honeywell Process Solutions offer ISA100.11a compliant starter kits and complete systems.
Yokogawa has introduced world's first wireless soluton based on ISA100.11a standards including wireless Gateway with pressure and temperature transmitter.

In May 2009, the ISA100 standards committee voted to approve ISA100.11a, "Wireless Systems for Industrial Automation: Process Control and Related Applications".

On September 9, 2009, ISA officially released ISA100.11a

In 2010, the ISA100 committee approved a major corregendum to the 2009 edition of the standard reflecting comments received from organizations implementing the standard, and other commentors seeking clarification. The 2010 edition of the standard was submitted to the IEC SC65C in the form of a PAS (Publicly Available Specification) and as a New Work Item for international standardization. In this form, it has been numbered as IEC 62734.
