The Wi-Fi-zation of things

Big innovations in power consumption and management are making it possible not only to extend battery life for Wi-Fi smartphones, but also to embed Wi-Fi into swarms of new devices and now even wireless sensors: medical monitoring devices, building control systems, real-time location tracking tags and consumer electronics. The result is the ability to continuously monitor and collect data, which can be personalized based on a user's identity and location.


"There's nothing that other contemporary limited-distance RF technologies can do that Wi-Fi can't," writes wireless consultant and Network World blogger Craig Mathias.

"With an enterprise wireless LAN, this infrastructure is already in place," says Atheros' McFarland. "Just add the low-power sensors."

Embedded Wi-Fi vendor Summit Data Communications recently announced 802.11a radios in various plug-in formats to let devices use the uncrowded 5GHz band. Start-up Gainspan offers 11bg Wi-Fi radios, with an IP software stack, that use so little power that wireless sensors can run for years on standard batteries. And Redpine Signals offers a single-stream embedded 11n radio.

LONDON--(BUSINESS WIRE)--Growing interest and investment in and funding for improved building energy management will help fuel demand for products and applications using IEEE 802.15.4 semiconductors.

Over the next five years, 802.15.4 chipset shipments will underpin a host of wireless sensor networks (WSNs) across home, building and industrial building automation, as well as Advanced Meter Infrastructures. This will help fuel the growth of the 802.15.4 chipset WSNs market from just over $10 million in 2008 to nearly $155 million in 2014, a Compound Annual Growth Rate of 87.9% over the period.

To date, the 802.15.4 market has grown steadily, based on proprietary point-to-point solutions and some ZigBee-based AMI infrastructure trials. According to ABI Research principal analyst Jonathan Collins, “With growing interest in the potential for wireless sensor networks in commercial building automation and management systems as well as smaller residential deployments, wireless is set to become a key development in the transition to smart energy management.”

Last ISAExpo, first outing for ISA100 wireless standard

ISA held its last ISAExpo in Houston.

In July this year the International Society of Automation (ISA) Standards & Practices Board (S&P) voted to approve the ISA-100.11a wireless standard Wireless Systems for Industrial Automation: Process Control and Related Applications, thereby making it an official ISA Standard. The approval of this major new industry standard by the ISA S&P Board certified that ISA's accredited procedures had been followed in the development of the standard.


This standard is intended to provide reliable and secure wireless operation for non-critical monitoring, alerting, supervisory control, open loop control, and closed loop control applications. The standard defines the protocol suite, system management, gateway, and security specifications for low-data-rate wireless connectivity with fixed, portable, and moving devices supporting very limited power consumption requirements. The application focus addresses the performance needs of applications such as monitoring and process control where latencies on the order of 100ms can be tolerated, with optional behaviour for shorter latency.
