Tiny cube may replace cellphone towers
MURRAY HILL, N.J. (UPI) -- Researchers say unsightly, sky-high,cellphone towers dotting the U.S. landscape may someday be replaced bysomething no bigger than a Rubik's cube.
Dubbed the lightRadio cube, the new device developed by Bell Labs isattracting interest from cellphone carriers around the world, The(Newark, N.J.) Star-Ledger reported Wednesday.
Current cellphone antennas must be both large and tall because theyrely on sending signals down and outward like an umbrella. Bell Labssay the lightRadio cube aims cellphone signals more directly, usingfar less power while providing 30 percent more capacity than currentcellphone towers.
Wireless researchers for Bell Labs scattered around the world took upthe challenge of replacing the giant towers with something morecompact, and Bell researchers in Stuttgart, Germany, came up with asolution: three 2-inch, stacked circuit boards for the antenna, radioand network connection that replaces the conventional antenna systemconnecting every cellphone call.
Dozens of mobile carriers across the world have approachedAlcatel-Lucent in Murray Hill, N.J., where Bell Labs is located,asking for demonstrations and trials, said Ken Wirth, president ofAlcatel-Lucent's 4G/LTE wireless networks business.
Five carriers in the United States, Europe and China are enrolled fortrials by the end of this year and the company hopes to begin makingthe devices commercially available within 18 months, he said.
