THE INSTITUTE Although 5G is poised to replace LTE for cellular communications, its base stations require about three times as much power. That is one challenge identified by members of the IEEE Future Networks Initiative in “7 Experts Forecast What’s Coming for 5G in 2020,” a round up of predictions for the technology. The initiative, an IEEE Future Directions program, is helping to pave the way for 5G.

“As more operators push 5G from demonstration sites into wider deployment, 2020 is going to be the year that power efficiency moves to the center of the conversation,” says IEEE Fellow Earl McCune, cochair of the initiative’s hardware working group

“To operate profitably, the 5G industry requires a sea change in transmitter radio frequency efficiency.” McCune is chief technology officer for Eridan, a company that builds extremely efficient radio hardware for 5G, based in Mountain View, Calif.”

 “Later this year could see the deployment of 5G-enhanced mobile broadband networks for portable devices used in malls, convention centers, and sports arenas, says IEEE Senior Member David Witkowski, cochair of the initiative’s deployment working group.

Witkowski is the founder and CEO of Oku Solutions and serves as executive director of the Wireless Communications Initiative at the nonprofit Joint Venture Silicon Valley, both based in San Jose, Calif.

IEEE Fellow Rod Waterhouse, cochair of the initiative’s publication working group, says areas of interest this year include the role satellites will play, vehicle-to-everything communication, and virtual medical care. Waterhouse is the CTO of Octane Wireless, in Hanover, Md.

Witkowski and Waterhouse both predict debates will continue over whether 5G will have harmful effects on humans and the environment. Overcoming such fears will require a deliberate response from industry, governments, and medical academia, Witkowski says.

The Unsung Inventor Who Chased the LED Rainbow

LEDs came only in shades of red—until George Craford expanded the palette

Walk through half a football field’s worth of low partitions, filing cabinets, and desks. Note the curved mirrors hanging from the ceiling, the better to view the maze of engineers, technicians, and support staff of the development laboratory. Shrug when you spot the plastic taped over a few of the mirrors to obstruct that view.

Go to the heart of this labyrinth and there find M. George Craford, R&D manager for the optoelectronics division of Hewlett-Packard Co., San Jose, Calif. Sitting in his shirtsleeves at an industrial beige metal desk piled with papers, amid dented bookcases, gym bag in the corner, he does not look like anybody’s definition of a star engineer.
