    "By comparison, 500 GHz is more than 250 times faster than today's cell phones, which typically operate at approximately 2 GHz, according to the organizations."


    I think that speaks for itself.

    Not quite... 500 Ghz (500 x 10^9) is a LONG WAY away from even the beginning of Infrared 3 TerraHz (3x10^12), and visible light does not start until about 430 TerraHz (4.3x10^14).
