In the era of 5G network, the US is lagging behind China. In order to partially offset this loss, the United States is planning to put resources to develop the 6G generation. The United States hopes that with the arrival of the 6G network, the country will become the leading country in terms of network technology of the future.
In March 2019, the US Federal Communications Commission (FCC) voted unanimously to open the 95GHz to 3THz band to serve the development of a 6G or 7G network in the future.
Dr. Ted Rappaport, a pioneer in wireless research at New York University and colleagues, published the latest article on IEEE. The team believes that wireless spectrum will increase even more in the 6G era. Accordingly, the frequency will increase from 100GHz (5G network theoretically) to 3THz when deploying 6G network.
Opening frequencies up to THz will provide a wider transmission space for wireless applications. The expanded bandwidth will contribute to the speed of transferring large data packets in less than a few seconds. Even a 6G network will create fast data transfer speeds equivalent to human brains.
Applications of 6G networks and bandwidth expansion will bring a lot of benefits. For example, training drone, AI. A current drone and combat weapon still has many limitations in calculating ability due to size limits.
However, in the era of 6G network with the support of remote AI control devices, a drone could effectively equal a fighter pilot. Although the control of drone with 5G network has shown some progress, only until the 6G network appeared with the ability to transfer data and calculate on par with human brain, how can we find this technology useful? .
Rappaport hopes to have more devices benefiting from the 6G network, such as night vision cameras, high resolution radars or security scanning technology. Impressive bandwidth speeds also allow us to switch from wireless fiber networks, relying primarily on fiber optic network infrastructure to centralized network connectivity to remote networks or data centers.
However, besides the benefits of 6G network technology, there are still many other issues to overcome. Examples include minimizing core technology and addressing the impact of spectrum on human health. In addition, 6G networks will need antennas with high orientation, in part because they are susceptible to interference when passing through the right air, especially with antennas above 800GHz.
Although researchers say that, like other technical challenges in the past, shortcomings of 6G networks will soon be resolved in the near future, such as reducing power consumption when transmitting data. whether or not the antenna has a wide coverage while the size is getting smaller. If all these conundrums are solved, a smartphone that supports 6G will certainly not be too thick and suitable for all users.
