Using Terahertz frequencies presents the same issues that carriers have had to deal with when trying to set up 5G connectivity in the mmWave band (24GHz to 100GHz). First, THz signals do not travel long distances and they have trouble penetrating clouds and fog. On the other hand, terahertz communications allow wireless transmissions to be almost as good as transmissions made over fiber.
The terahertz transmission test delivered download speeds nearly 169 times faster than the results of this 5G test
The report says that THz, with its larger transmission bandwidth and faster transmission speeds, is becoming one of the most important technologies when discussing 6G. Not expected to launch before 2030 (although South Korea hopes to best that by two years), 6G wireless should produce download speeds up to 100 times 5G rates. This will obviously lead to faster download and upload speeds for smartphone users and should lead to incredible new services in the entertainment (including gaming), automobile, and healthcare industries as well as others.
