Zigbee devices are designed to last five years on a pair of AA batteries.
Wi-Fi is nice, but the real action will be in ZigBee, sensor networks, and the RoboNet.
At a dollar a chip, ZigBee transceivers could even be built into toasters and coffee pots.

E-MiLi can also be used with other wireless communication protocols that require idle listening, such as ZigBee.

The example ZigBee stack for the chip is still vulnerable to this attack, even after recent patches!
Already, a handful of meter makers have begun incorporating ZigBee transceivers into their products to do just that.

With Zigbee in place, Ember began selling chips to others and building nodes that could send and receive data.
At least three major wireless protocols -- INSTEON, ZigBee and Z-Wave -- vie for adoption in wall switches for lighting.
Nice start, but it pales next to the prospect of ZigBee, an emerging wireless standard for short-range machine to machine communications.
ZigBee is not for big corporate servers monitoring each others' transactions, but, rather, it's designed to link up an unimaginable number of tiny devices.
That's a pretty strong foundation to build from especially if your home is already equipped with ZigBee devices like automated light switches, window controllers, and locks.

The Linkbot itself has two rotating hubs with absolute encoding, along with an accelerometer, buzzer, multicolored LCD and ZigBee wireless system with a 100m line-of-sight range.
The ZigBee wireless protocol was designed as a cheaper and lower-power alternative to Bluetooth and Wi-Fi for embedding in lighting switches, thermostats, smoke detectors and other sensors.

For example, General Electric has developed the a home energy management platform that uses a ZigBee network protocols to establish communication channels between household appliances.

RF, once touted as the ultimate home-networking standard, has been wiped out by Wi-Fi, but newer technologies such as ZigBee and ultrawideband are now in the running too.
Poor took a lead role in creating a rival standard called Zigbee, which moves data only one-fourth as fast as Bluetooth but can handle hundreds of devices at once.
They also have wireless chips that will use the ZigBee standard, a sort of longer-range version of Bluetooth, to communicate with a future generation of wireless appliances and thermostats.
Assembling HEX has cost the proverbial arm and a leg -- "tens of thousands of dollars, " says Haygood -- and is controlled remotely using a Zigbee USB dongle attached to his laptop.
There have been previous efforts to build sensor nets by various private companies, but, like the Internet and Wi-Fi, Zigbee uses open standards, lowering the costs and risks associated with building the technology.
ZigBee is good for low-speed, low-power transmissions (automated meter readings, for example), while ultrawideband is ideal for linking up home-entertainment devices, though it is currently mired in a standards war (see article).
The latest version, which we had the opportunity to play around with at CES, features a 2.8-inch display, as before, but adds some much welcomed additions, including support for 802.11ac, Zigbee and Z-Wave.
While domesticated robots are becoming a ( frighteningly) common inclusion in techno-friendly homes, Korean 'bot manufacturer ED has a home-ready robot that sports a plethora of communication venues including ZigBee and RFID.

Meantime, ibm executive Allan Schurr expects retailers like Home Depot eventually to stock simple ZigBee devices that look like lamp timers and can turn energy-hogging appliances on and off according to commands that consumers send over the Web.
In January of last year, cybersecurity researcher Travis Goodspeed gave a presentation at the S4 conference in Miami where he described a way to bypass encryption on Zigbee wireless chips, which some smart electric metering systems would use to communicate.
FORBES: Researcher Throws A Wrench In IBM And HP's Sensor Networks
The details of connectivity and interoperability are scarce but we do know that the appliances support both WiFi and ZigBee connectivity in order to communicate with each other, your in-home smart meter, and with smartphones when outside of the home.

As Technology Review's Physics arXiv blog reports, they've devised a means to modify a standard 802.15.4 wireless network (commonly used by home automation services like ZigBee) to actually "see" movement through walls, and with some degree of accuracy, no less.

Attaching appliances to a power socket via a smart plug containing sensors and a ZigBee transceiver allows information about the appliances' power consumption to be beamed automatically to a broadband router within the home, and thence to a web server located elsewhere.

ZigBee is a protocol that works on the 802.15.4 spectrum (WiFi is also known as 802.11 for its slice of spectrum.) As a short-range, low-power protocol, ZigBee is suited for two-way communications among small devices, and can be used to build self-organizing networks of devices.
Meantime, ibm executive Allan Schurr expects retailers like Home Depot (nyse: HD - news - people ) eventually to stock simple ZigBee devices that look like lamp timers and can turn energy-hogging appliances on and off according to commands that consumers send over the Web.
