Details:Radio technology is subject to more national and international regulation than many other technology of interest to EEs because of the finite nature of spectrum and the possibility of interference to other spectrum uses. But many of the basic concepts of spectrum policies were adopted decades ago when the frequencies involved had very difference characteristics than the upper reaches of spectrum that are becoming feasible for use today. In addition today’s technology gives options that were not imaginable decades ago. In the US there are no rules that allow timely access to spectrum for technologies above 95 GHz. Innovators face years of uncertainty on whether their technology can enter commercial use and this in turn may stifle commercial R&D. In the US and internationally there is also ambiguity at present for access to spectrum above 275 GHz. Until 1995 the limit of FCC rules was 40 GHz and a decision that year moved it up to 77 GHz resulting in a spurt of new R&D, some of which fostered the now pending 5G cellular technology. This talk with review the issues of moving the 95 GHz barrier to new technology further up in the spectrum and the resulting potential for technological innovation.
