5G hasn't reached many parts of the world yet, but Japan seems to have started preparations for 6G. We say this because a Japanese consortium recently unveiled the world's first high-speed 6G prototype device. It is claimed to be capable of transmitting data over 330 feet at a speed of 100 gigabits per second (Gbps). This speed is 20 times faster than existing 5G processors and its overall speed is 500 times faster than the average 5G phone speed.
This means that the day is not far when it will take us not minutes but seconds to download a big movie. According to TechReport, with 6G speed you can download 5 HD movies in one second.
The test was conducted at a distance of 100 meters
The prototype device has been jointly developed by four major Japanese telecommunications companies, DoCoMo, NTT Corporation, NEC Corporation and Fujitsu. These companies were working on this device for a long time.
The consortium announced successful test results on April 11, where the companies revealed that prototype devices could achieve speeds of 100 Gbps indoors using the 100 GHz band and 100 Gbps using the 300 GHz band.
Speed may be reduced in real life
Although these speeds are impressive, don't get your hopes too high already Since only one device has tested 6G, the network technology also has its disadvantages.
5G, the current gold standard in connectivity, has a theoretical maximum speed of 10 Gbps. However, real-world speeds are generally much slower, averaging around 200 megabits per second (Mbps) for T-Mobile users in the US.
Frequency can be a challenge
One reason for such low speeds is the high frequency bands used by 5G. Higher frequency may also mean faster, but it also has several disadvantages. They limit the distance a signal can travel.
6G takes this a step further and uses even higher frequency bands than 5G. This means that 6G devices will have difficulty achieving the frequencies needed for quick downloads. These tests were conducted at distances of more than 330 feet (100 m). Therefore, challenges like walls and rain can disrupt the 6G signal to a great extent.
