Industrial wireless networks — comparing the standards: Part 2
13 July, 2015 by Glenn Johnson, EditorIn Part 1 of this article, we reviewed the history of wireless sensor networks (WSNs) and defined the common standards used in industrial wireless networks. In this part we compare more closely the two prevalent wireless mesh network standards designed for use in process plants: WirelessHART and ISA100.11a.
Industrial wireless networks - comparing the standards: Part 1
15 June, 2015 by Glenn Johnson, EditorToday wireless instrumentation is becoming more commonplace in process plants and is a more specialised implementation of wireless sensor network (WSN) technology. In this two-part article we look at the predominant industrial wireless standards.
ISA100 wireless standard approved by IEC
22 September, 2014The International Society of Automation (ISA) has announced that ANSI/ISA-100.11a-2011 has been approved by the International Electrotechnical Commission (IEC) as an international standard.
Holding industrial wireless vendors to account
25 October, 2010While wireless technology has moved well beyond simple point-to-point connectivity, the fundamental tenets of the technology remain the same. Some basic understanding of RF technology can empower more informed decision-making in relation to which wireless technology to deploy relative to application need.
ISA ratifies ISA-100.11a industrial wireless standard
16 September, 2009The ISA Standards & Practices Board (S&P) has voted to approve the ISA-100.11a wireless standard, making it an official ISA Standard.

by Joel K Young, Digi International
Over the past few years, mesh networks have become more popular, following the trend to create more wireless things. As with other technology trends, as mesh networking has developed, so has a plethora of different mesh networking technologies and architectures.
WirelessHART: the right standard at the right time
02 March, 2009The WirelessHART standard provides a robust wireless protocol for the full range of process measurement, control and asset management applications.
Mixing multiple wireless technologies - Part 2
28 February, 2009 by Joel K. Young*In the Part 1 of this article, Joel Young explored cellular, Wi-Fi/802.11 and WiMAX/802.16 technologies. In this second part, he examines ZigBee/802.15.4 and provides some guidelines for planning a successful commercial or industrial deployment.
Mixing multiple wireless technologies - Part 1
12 January, 2009 by Joel K. Young*Joel Young explores how to mix different wireless technologies, including cellular, Wi-Fi/802.11, WiMAX/802.16, ZigBee/802.15.4 and proprietary wireless, to form a successful commercial or industrial deployment.
Ask the question: making a strategic wireless decision
14 November, 2008 by Jeff Becker*Industrial users have historically been a bit cautious about taking advantage of wireless technology. This caution is generally due to concerns related to critical infrastructure security and reliability. However, if the right wireless solution is chosen, adopters of industrial wireless technology can have the best of both worlds.
WirelessHART becomes international communication standard
30 September, 2008The WirelessHART Communication Specification (HART 7.1) has been approved by the International Electrotechnical Commission (IEC) as a Publicly Available Specification (IEC/PAS 62591Ed. 1), making it the first officially released industrial wireless communication standard.
More features for ZigBee
10 October, 2007The ZigBee Alliance, a global group of companies creating wireless solutions for commercial and industrial use, has added features to the ZigBee specification to give manufacturers greater flexibility when designing compatible products.
Cooperative effort to improve wireless technology
08 October, 2007Fieldbus Foundation, HART Communication Foundation, and Profibus Nutzerorganisation have begun a cooperative effort to improve implementation of wireless technology in the manufacturing and process industries.
Open wireless communication standard for process control
20 September, 2007The Hart Communication Foundation (HCF) has released the HART 7 specification, enabling more capabilities for communication with intelligent field devices, including Wireless HART.
