Researchers behind the new technique say they have managed to get around this problem by using a wide range of frequencies between a few gigahertz and a few terahertz, which is between 100 and 10,000 times lower in frequency than the visible light that passes easily through labels and packaging.
2 gigahertz offers roughly the same performance as current top-of-the-line computers, and 512 megabytes of RAM ensures that the memory capabilities of the Playstation 3 match up with its processing power.
Although the new device can switch on and off at only the modest frequency of 3 gigahertz, frequencies 100 times as rapid as that appear feasible, Holonyak says.
