Wireless communications technology and devices have become such an important part of daily lifestyles. The concept of 5G is simple: When bandwidth is gone at lower frequencies, reach into the mmWave frequency range for the bandwidth needed for fast wireless data rates over shorter distances. but what if 5G bandwidth is all gone?
----->Here's it comes the 6G technology:
6G is short for sixth-generation of wireless networks, which will be the successor to 5G technology. Like all previous generations, 6G is expected to expand on the capabilities of 5G. That will mean expanding on speed and data capacity, plus the innovations regarding IoT or the Internet of Things that 5G is widely expected to usher in.
At September’s Mobile World Congress Americas 2018, FCC Commissioner Jessica Rosenworcel suggested that 6G could feature terahertz (THz) frequency networks and spatial multiplexing with multiple simultaneous beams of data transfer with a high level of network densification. This could be accomplished with miniaturized base stations embedded ubiquitously in the environment everywhere. While Rosenworcel said these technologies are far away, spectrum policies need rethinking now in advance of 6G including valuation, auctions, and distribution.
6G is likely to be a combination of higher frequencies (mmWave and perhaps THz), integration of blockchain and AI in SDRs, and possibly new modulation schemes and techniques to achieve vast improvements in capacity, throughput, and latency.
