ON World’s 2012 survey shows continued growth and new opportunities for wireless sensors
Despite a challenging economy, the industrial Wireless Sensor Network (WSN) market has doubled over the past two years. A recently completed ON World survey of 216 industrial automation professionals, in collaboration with ISA, HART Communication Foundation (HCF), and the Wireless Industrial Networking Alliance (WINA), points to increasing WSN adoption and expanding markets.
When ON World started researching industrial wireless sensing 10 years ago, deployments of more than 20 nodes were rare. Today, network densities are increasing, and several sites have deployments of more than 3,000 nodes. What is responsible for much of this growth? The 2012 survey indicates this is a result of increased education, reliability of today’s WSN systems, maturing wireless mesh solutions, and a rapid migration to industry standards, such as WirelessHART and ISA100.11a.
Within the next five years, installed wireless industrial field devices will increase by 553% when there will be nearly 24 million wireless-enabled sensors and actuators, or sensing points, deployed worldwide. By 2016, 39% of deployed nodes will be used for new applications that are uniquely enabled by WSN technology. WSN is impacting industrial automation by disrupting wired automation, extending wired sensor networks, and driving new sensing and control solutions. …
