Wireless adoption within industrial automation is not new, but it has been limited by the proprietary nature and cost of the available products. Over the past few years, support for a standard silicon platform and standardized communications protocols have emerged to boost WSN within industrial automation. However, reliability and longevity are essential attributes demanded within the industrial automation market and so proven proprietary technologies continue to be used. Among the deterrents often cited for standardized WSN deployment is the fact that — despite standardization on the IEEE 802.15.4 silicon platform — there is still concern regarding the multiple protocols that may yet be adopted using that silicon. This report analyzes the market opportunity for WSN in industrial deployments, detailing where it will find traction (and where it will not); the implications of the key standards efforts including Wireless HART, ISA-100.11a, and WIA-PA; the implications WSN adoption will have for the market; and the key players involved in making WSN a reality in industrial automation.
