This part of IEC 62657, which is a technical specification, specifies the fundamental assumptions, concepts, parameters, and procedure for wireless communication coexistence.
This specification provides guidelines, requirements, and best practices for wireless communications’ availability and performance, covering the life cycle of wireless communication coexistence to help the work of all persons involved with the relevant responsibilities to cope with the critical aspects in each phase of wireless communication coexistence management in an automation plant.
Additionally this specification provides a common point of reference for wireless communication coexistence for industrial automation sites as a homogeneous guideline to help the users assess and gauge their plant efforts. Life cycle aspects include: planning, designing, installation, implementation, operation, maintenance, administration and training.
This specification deals with the operational aspects of wireless communication coexistence regarding both the static human/tool-organization and the dynamic network self-organization.
This technical specification specifies coexistence parameters and how they are used in an application requiring wireless coexistence.
NOTE Measurement methods of parameters could be the subject of a later edition.
