New Communication Standards for Smart Grid Metering Devices
Among the efficiencies promised by the smart grid is the use of metering devices that not only report usage to utilities but also inform users how to schedule consumption to lower-cost off-peak hours or even control that consumption automatically. Two new IEEE standards provide multisource "plug and play" environments for the millions of metering devices in the field now and in … [Read more...]

Wireless Approvals for Japan: A Hiro's Tale
Hiro dug into his soup. “Did your dad fight in the war?” Nodding, slurping up fat udon noodles, “Korea,” pausing and picking up a napkin to dab his chin. “My father was an engineer, highways and bridges, mostly in the North.” Hiro put down his napkin, laid his fast-food chopsticks across his bowl and picked up the chopstick wrapper. He meticulously folded the long paper in … [Read more...]
