6G will push into much higher frequency bands, specifically the Terahertz (THz) spectrum (from roughly 0.1 THz to 10 THz). This enormous available bandwidth will enable unprecedented peak data rates, potentially reaching terabits per second (Tbps) or even tens of Tbps.
Detailed Explanation
6G technology is expected to advance communication by utilizing the Terahertz spectrum, significantly beyond the capabilities of 5G. The THz frequencies provide a much larger bandwidth that can support immensely faster data transmissions. For instance, while current data speeds are impressive, the potential of THz could allow us to transfer massive amounts of data much more quickly. This capability will support innovative applications requiring high throughput, such as holographic communications and ultra-fast wireless backhaul options.
Examples & Analogies
Imagine downloading a high-definition movie in seconds instead of minutes. Just as highways with more lanes can accommodate more cars simultaneously, the THz spectrum offers a 'wider highway' for data, allowing more information to travel through it at once.
