People not only talk on the airwaves, they increasingly expect their gadgets to do the same. The trend began in the late 1990s with Bluetooth, which provided 1 megabit of data per second. Then Wi-Fi and the IEEE 802.11 standard pushed the rate to 100 Mb/s. Now ultrawideband systems are going five times as fast as that.

In principle, such radio links, operating over short ranges, could replace the cables that now clutter our homes and offices, eliminate the speed penalty of going wireless, and even allow portable devices to off-load computing work to a nearby base station. The devices could thus shed hardware to become smaller, lighter, and cheaper.

The word home evokes a sense of belonging and welcoming. IEEE aims to create a similar feeling by offering services for members at every stage of their career and by building a community among them.

IEEE President and CEO K.J. Ray Liu is committed to making IEEE the professional home for members. As he announced in his March column in The Institute, he’s doing that by “examining ways in which the organization could evolve to best meet the needs of all technical professionals in the years ahead.”

Home Heating With Hydrogen: Ill-Advised as It Sounds

Several studies reveal serious drawbacks

Hydrogen, if it comes from splitting water with renewable electricity, has its role as a climate-friendly energy source. It could help decarbonize challenging sectors like heavy industry, shipping, and aviation.

But hydrogen makes absolutely no sense for heating homes and buildings, according to a new review of several international studies. It is simply much too expensive and inefficient for that purpose, says Jan Rosenow, Europe director at the Regulatory Assistance Project, an energy think tank in Brussels, who authored the commentary published in the journal Joule.

Learn how to measure and reduce common mode electromagnetic interference (EMI) in electric drive installations

Nowadays, electric machines are often driven by power electronic converters. Even though the use of converters brings with it a variety of advantages, common mode (CM) signals are a frequent problem in many installations. Common mode voltages induced by the converter drive common mode currents damage the motor bearings over time and significantly reduce the lifetime of the drive.
