6G will completely redefine what we know as possible, though this will also pose challenging requirements, which were discussed in previous posts of this series. And even though it seems like we are fresh off the buzz generated by 5G, 6G is not eons away.When this technology arrives, it will encompass innovations ranging from new spectrum to new materials and antennas, new channels, and new devices — collectively referred to as the new elements.In this post, I briefly cover the connotations of these new elements, along with some of the opportunities and challenges they create.Read the previous posts in the series here:6G: The Next Horizon.Enter new spectrumIn line with the trend set by previous iterations of wireless transmission technologies, 6G will explore even higher frequency bands — think the sub-THz spectrum. This will happen within a multi-layered framework that also takes advantage of low- (700–900 MHz) and mid- (3–5 GHz) bands to make wide coverage possible.Low- and mid-bands...
