In March 2019, the US Federal Communications Commission (FCC) agreed to extend the frequency band (frequency of electromagnetic waves used to transmit communications between devices using wireless technology). from 95GHz to 3THz for a 6G, 7G test or any next generation network technology. At that time, AI’s ability can be on par with the human brain.

At New York University, Dr. Ted Rappaport and his colleagues pioneered the study of wireless networks. This group of researchers believes wireless systems will grow even more in the 6G era . Accordingly, if the band of 5G network can reach about 100GHz (Gigahertz), then at 6G network, the band can reach 3THz (terahertz).

For example, an unmanned fighter will be limited in computing power by its size limit. However, in the 6G era in the future, with the remote-controlled AI device, its combat performance will be equivalent to an excellent pilot.

Although remote control of unmanned aircraft has been able to perform effectively in the 5G era , users can purchase a "terminal" (type of machine with a keyboard and a screen to link to). lost with the central processor in the computer system) has the computing power at the human brain level for about 1,000 USD.

Dr. Rappaport’s team also hopes that many other devices will benefit from this 6G network development project. For example, millimeter-wave cameras with night shots, high-resolution radars, and scanners check the safety of the human body. The "massive" bandwidth will also allow switching to wireless fiber networks based on fiber optic infrastructure and data centers.

In addition to the benefits that brings 6G, still many problems to be overcome in the future we l anybody . Typically, the reduction of core technologies and minimizing the impact of millimeter waves (extremely high bandwidth frequencies) on human health. In addition, 6G waves also require high directional antennas because they are very susceptible to interference in the atmosphere, especially antennas with frequencies above 800GHz.

However, the researchers are optimistic that these technical challenges will be gradually resolved in the future like the 5G network.
