In the era of the 5G network, the United States 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 US hopes that by leading 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 the 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 his 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 a 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 the 6G network will create fast data transfer speeds equivalent to human brains.
Applications of the 6G network and bandwidth expansion will bring a lot of benefits. For example, in training drone, a current drone has still limited computing power of its onboard equipment due to its size limitation. 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 fight control of drones with the 5G network has shown some progress, only until the 6G network appears with the ability to transfer data and calculate on par with the human brain, we will find how useful this technology is.
Rappaport hopes to have more devices benefiting from the 6G network, such as night vision cameras, high-definition radar, and terahertz human body safety scanning. The impressive bandwidth speeds also allow us to switch from wireless fiber networks, relying primarily on fiber-optic cable infrastructure to network backhaul and data center connectivity.
Besides the benefits of 6G network technology, there are still many other issues to overcome. For example, minimizing core technology and addressing the impact of the spectrum on human health. In addition, the 6G network will need antennas with high orientation, in part because they are susceptible to interference when traveling through the atmosphere, especially with antennas above 800GHz. However, the researchers said that, like other technical challenges in the past, the shortcomings of the 6G network will soon be resolved in the near future, such as reducing power consumption when transmitting data or reducing the size of the ultra-high-gain antenna. If all these difficulties are solved, a smartphone that supports 6G will certainly not be too thick and suitable for all users.
