What a mesh!
The ins and outs of mesh networking — Part 2
In the first part of this article we discussed the basics of wireless mesh networking and what criteria you should use when assessing a mesh networking technology. This month we compare four available technologies. -
What a mesh!
The ins and outs of mesh networking — Part 1
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. -
Data acquisition: no limits — digital wireless technology using the IEEE802.15.4 ZigBee standard
Wireless networking of data capture devices using the ZigBee protocol provides a more efficient and fault-tolerant method of data acquisition without wires. -
WirelessHART: the right standard at the right time
The 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
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
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
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.

ISA ratifies ISA-100.11a industrial wireless standard
The ISA Standards & Practices Board (S&P) has voted to approve the ISA-100.11a wireless standard, making it an official ISA Standard. -
WirelessHART becomes international communication standard
The 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. -
Open wireless communication standard for process control
The Hart Communication Foundation (HCF) has released the HART 7 specification, enabling more capabilities for communication with intelligent field devices, including Wireless HART. -
Why factories struggle with wireless technology
Factories have much to gain from wireless technology, such as robot control, RFID tag monitoring, and local area network (LAN) communications. Wireless systems can cost less and offer more flexibility than cabled systems. But factories are challenging environments for wireless systems, as verified by tests conducted recently by the National Institute of Standards and Technology (NIST) in the US. -
Faster Wi Fi gets go ahead
At the Institute of Electrical and Electronics Engineers (IEEE) taskgroup meeting in Hawaii recently, there was an agreement over the next high speed Wi-Fi standard, 802.11n. -
More features for ZigBee
The 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
Fieldbus Foundation, HART Communication Foundation, and Profibus Nutzerorganisation have begun a cooperative effort to improve implementation of wireless technology in the manufacturing and process industries.
