Beyond WiMAX

Research is already underway into WiMAX’s successor. Like other 802.xx IEEE wireless data systems, WiMAX uses centimeter-range radio waves to carry digital data. In contrast, millimeter-wave technology operates at radio frequencies of between 60 and 100 GHz, giving the waves lengths of 3-5mm. It’s a part of the radio spectrum commonly used for radio astronomy and high-resolution radar systems, and it’s largely unregulated and unused — particularly compared to the crowded, longer wavelength end of the spectrum.
