What is the ISA 100.11a Standard?


#1

ISA100.11a Standard

The ISA100.11a standard was created to provide reliable and secure wireless operation for non-critical monitoring,alerting, and control applications.

The standard defines the specification of
-protocol suite
-system management
-gateway
-security

It is intended for low data rate wireless connectivity with fixed,portable,and moving devices supporting very limited power consumption requirement.

The standard addresses performance needs of application such as monitoring and process control where latencies on the order of 100 ms can be tolerated.

Fundamentals of the ISA100.11a standard

1.ISA100.11a wireless standard is an open communication protocol

2.The standard is flexible,supporting a wide range of protocols

3.The standard uses the OSI seven layer model for design basis,leveraging existing best practice networking standard.

4.Physical and data link layers use the IEEE 802.15.4 radio standard referencing the 2.4 GHz frequency band for global deployment

5.Allows flexibility by using an algorithm to determine the best link formation

6.Over the air firmware,configuration and provisioning

Benefits of Implementing with ISA100.11a

Predictable and inter-operable performance

Flexible and deterministic operation

Ensure reliable and secure data transmission

Support routing and non-routing device

Time and cost savings for installation and validation

Scalable to support thousands of device
