Nokia’s Home Control Center to Use Z-Wave

Energy monitoring via mesh networking and is planned.

Also Filed in Thermostats and Sensors

December 09, 2008 | by Steven Castle

Z-Wave wireless networking developer Zensys has been touting the mesh network’s green benefits, and that may become more of a reality with the a Z-Wave-enabled Nokia Home Control Center that will monitor home applications and lighting as well as the reduction of electricity, gas, water consumption and carbon dioxide emissions—and all from a handheld device like a smart phone.

Z-Wave says the Nokia Home Control Center will allow compatibility and control within the interoperable Z-Wave ecosystem that’s over 300 products strong. The Z-Wave ecosystem lets the user monitor and control their electricity usage, switch devices on and off, and monitor home systems and devices such as temperature controls, security cameras, and motion detectors.

A user can take control of the home, locally or remotely, from the palm of a hand using a Nokia handheld device.

There has been some debate over whether Z-Wave or rival mesh tech ZigBee will be the better solution for home-based energy monitoring systems that can report on your electricity usage, for example. ZigBee is being considered in some smart meter trials conducted by utilities, while Z-Wave has maintained that it is better positioned in devices inside the home.

I saw some Z-Wave systems touting their green-ness at the recent Electronic House Expo , but it’s clear to me that neither Z-Wave nor ZigBee has a strong foothold on this category. Nokia’s Home Control Center, reportedly due in late 2009, may be a start.

Low-power chips bring WiFi to remote sensors

A Californian company claims to have overcome the power consumption problems that have so far prevented WiFi from being used to gather data from battery-powered sensors. Sunnyvale-based GainSpan – which was formed in 2006 as a spin-off from the chip-maker, Intel – claims that its technology will allow WiFi transmitters to operate for up to ten years, powered by a single AA battery.

Until now, sensor transmission networks have relied on dedicated technologies, often with a limited transmission ranges. Although there is a standardised wireless data transmission technology known as Wifi (defined in IEEE 802.11), it has a relatively high power consumption and has therefore not been suitable for collecting data from remote battery-powered sensors which, ideally, should be able to operate for long periods with no maintenance.

GainSpan says it has a found a way of implementing WiFi which has a much lower power consumption than normal, allowing transmitters to operate for several years before the single battery needs to be replaced. The advantages of using WiFi in this way include: seamless integration with existing WiFi networks; easy communications with higher-level systems; the wide availability of software tools; and potentially lower costs.

GainSpan, which has recently raised $20m-worth of funding, has been developing both the low-power custom chips (shown above), and the software development kits that will allow OEMs to implement the chips rapidly.

Harry Forbes, senior analyst at the ARC Advisory Group, believes that GainSpan’s low-power WiFi technology has the potential to "change the game".

"While wireless sensor networks have seen steady growth over the past few years," Forbes points out, "their market potential has, in fact, been hindered by power consumption issues and lack of mature standard-based solutions". He suggests that GainSpan’s development will allow users to take advantage of the global WiFi standard and existing network tools to provide "the cost, energy savings and convenience needed to transform this market".

Another analyst, Sam Lucero of ABI Research, points out that "WiFi is more widely used and understood than many sensor-networking technologies being developed. Rather than employ a dense cluster of meshed nodes, which are inherently more complex to network and manage, WiFi is a simpler start, reducing complexity of the network topology."

GainSpan’s 10 x 10mm WiFi chips incorporate two 32-bit ARM7 microcontrollers, a real-time clock and power management functions, Flash and SRAM memories, and multiple I/Os. Potential applications are said to include motor monitoring, production tracking, meter reading and environmental observations. The chips will cost $15 in 10,000-unit quantities.

GainSpan, Ekahau Partner for Wi-Fi Location Tags

Oct 14, 2008
GPS World

Wi-Fi chip maker GainSpan Corp. and Wi-Fi positioning service provider Ekahau Inc. have embarked on a strategic partnership, integrating Ekahau's technology with GainSpan's embedded software on its GS1010 ultra low power system-on-a-chip (SoC).

This will allow GS1010-based Wi-Fi sensor nodes and location tags to work with the Ekahau Positioning Engine (EPE), according to the two companies. As a part of the agreement, Ekahau will license the EPE and Ekahau Vision application to GainSpan customers; this will enable them to add location-awareness to their applications.

"The Ekahau Real Time Location System (RTLS) is targeted at providing location awareness in environments where technologies such as GPS do not perform adequately. Unfortunately in the asset and people tagging industry these environments are all too common," said Vijay Parmar, GainSpan president and CEO. "Ekahau RTLS technology and GainSpan's low power Wi-Fi SoC provide a reliable mechanism for people and asset tracking even in these environments."

GainSpan and Ekahau have already started actively marketing the combined solution to OEMs and channel partners worldwide, the companies said. That includes electronics giant Samsung. "Technology offered through this partnership provides an extremely appealing solution," said Woochul Shin, director of solutions marketing for theVSS Business Team at Samsung Electronics Co. Ltd. "Our team is actively designing product offerings based upon the combined solution and we hope to release products to the market within next several months."

GainSpan Corporation, an Intel spin-off, has announced the availability of a Wi-Fi cold storage monitor that provides up to 5-10 years of battery life. SentinelPro, the product brought out by Aginova, a manufacturer of specialized wireless subsystems, is based on GainSpan's ultra-low power GS1010 Wi-Fi SoC. Leveraging the existing ubiquitous Wi-Fi network, the new solution offers the most advanced Wi-Fi sensing hardware, a portable alarm unit, and a comprehensive software package for monitoring, reporting, and storing of critical storage condition data over time.

With SentinelPro, authorized personnel can view precise data over enterprise class security links, and provide alerts in the event that environmental conditions vary beyond a specified range. The system can page, email and visually alert any computer screen whenever food, lab samples, pharmaceuticals or other temperature sensitive items are outside prescribed parameters.

Utilizing Wi-Fi for temperature monitoring enables a cost effective way to improve patient care and maintain regulatory compliance while providing automated and detailed reports on any piece of equipment for any time period for JCAHO, AOA, CAP, FDA, USDA or the Health Department. In addition, it can also provide temperature logs, operating parameters, alarms and corrective actions to be taken while eliminating human error and the cost of manual temperature documentation.

According to Vijay Parmar, CEO, GainSpan Corporation, "Wireless sensor networks have seen steady growth over the past few years and the market for it has immense potential. GainSpan's solutions are designed to support broad range of embedded applications thus enabling customers to customize to their product needs. This solution is a great example of that flexibility as it has been possible to develop a product around GainSpan's offering exactly addressing the need of the food and cold storage industry for more scientific and accurate monitoring and controlling of temperature."

In his comments, Ashok Sabata, CEO, Aginova said," We were using Zigbee, a non-standard wireless communications protocol, but with GainSpan we've been able to develop and get products to market much more quickly than ever before. And, because we're tapping into the existing infrastructure, installing and maintaining our products is relatively cheap-we've cut costs exponentially."

The software, developed by Aginova, is available in two packages: enterprise grade for integration into a customer's automation system or as a service running on Aginova secure servers. As a result, the new temperature monitoring solution provides the security, manageability, convenience and benefits of Wi-Fi along with 5-10 years of extended battery life.
