Scientists in Japan have transferred data at 100 gigabits per second in high-frequency wavelength bands over a distance of 330 feet for the first time.

5G signals are commonly transmitted in bands under 6 GHz and extended into bands of around 40 GHz — known as the “millimeter-wave bands,” according to 6GWorld.
6G, on the other hand, is expected to use higher-frequency bands, known as “sub-THz” bands, which are between 100 GHz and 300 GHz, according to Nokia. Transmitting in this region taps into the advantage of faster speeds but has the disadvantage of greater interference with the environment, with signals more likely to become blocked — particularly indoors.
Where the jump from 4G to 5G paved the way for much greater volumes of media consumption, the jump from 5G to 6G could lead to new technologies like holographic communication and smoother virtual reality (VR) and mixed reality experiences.
Because 6G relies on much higher frequency bands, however, we would need completely new infrastructure to transmit and amplify signals, while smartphones or VR devices would require 6G antennae.
In previous tests, scientists have achieved faster 6G speeds — but over much shorter distances. A different team of scientists in Japan, for example, demonstrated world-record 6G speeds of up to 240 Gbps but only at 66 feet (20 m), publishing their findings Feb. 10 in the journal IEICE Electronics Express.
