Samsung has already tested 6G
Although 5G is still far from being widespread throughout our country, there are already those who think about 6G! Samsung would successfully test next generation technology that could go up to 1000Gbps.Samsung has not just started working on 6G, the first studies have started as early as 2019. It may seem early, however 5G is one technology that was developed for many years before its commercial application that we are seeing nowadays.
The Korean company unveiled a white paper last year that predicts mobile communications in the frequency range of Terahertz. Recently, a first connection with a 2GHz bandwidth was made in collaboration with the University of California at Santa Barbara in the United States.
According to Samsung's predictions, 6G connectivity technology could be officially implemented starting in 2028 and allow transfer rates of 1Tbps (125GBps!) and operate on latencies in the order of tenths of a millisecond (0.1ms).
We are not in the least close to definition and use of the new standard, however, the Korean company predicts that 6G will occupy some of the bands currently used by 4G and 5G but also beyond, up to 3000GHz.
Here is part of the prototype equipment of Samsung “In collaboration with the University of California at Santa Barbara (UCSB), Samsung was able to test a first Terahertz connection as part of the IEEE International Conference on Communications (ICC 2021). An end-to-end connection in the 140GHz frequency range was established using beamforming. In this live transmission test, a data rate of 6.2Gbit / s was achieved in the Terahertz spectrum at 140GHz over a distance of 15 meters, ”the French colleagues of Frandroid write.
But what good would all this 6G speed be? According to Samsung, one of the uses could be found in holograms. An 11.1 Gigapixel hologram shown by a 6.7-inch display would require 0.58Tbps throughput. On the other hand, a human-sized hologram may require several Tbit / s.
Will we really use holograms to communicate in 2028? Only time will confirm this, however it is interesting to observe the development of technology and the direction it will take in the future.

Samsung's first 6G prototype demo taps into terahertz frequencies
It may feel like 5G networks are only just finding their feet and becoming mainstream, but the march of technology rarely rests. The next iteration, 6G, is already in the works, and Samsung has now demonstrated its first 6G prototype 6G system in an over-the-air test, using terahertz (THz) frequencies.
As you’d expect, the main advantage of 6G is faster data rates and lower latencies. The peak data rate is expected to eventually be up to 50 times faster than 5G, pushing it into the range of terabits per second. Latency, meanwhile, is expected to drop to just one-tenth that of 5G, and together these advances should help the tech transmit much more data-intensive content, such as 8K resolution, VR and holographic video.
Currently, 5G communications operate at frequencies up to about 40 GHz, but 6G would push that beyond 100 GHz, tapping into the as-yet-unutilized THz spectrum. The new tech would also give a boost to bandwidth too, which for 5G tops out at around 400 MHz.
For the new test, researchers at Samsung and the University of California, Santa Barbara demonstrated a system with 140 GHz frequency and a bandwidth of 2 GHz. In doing so, they managed to transmit data at 6.2 Gbps over a distance of 15 m (49 ft).
That’s a decent step up from 5G’s speed record of 5.23 Gbps, and even that was with the help of some 4G frequencies in a mostly experimental setup. But still, it’s far short of what 6G could eventually be capable of – data transfer rates of up to 1 Tbps, which is 1,000 Gbps.

The system consists of a phased array transmitter with 16 channels, receiver modules, and a baseband unit that processes signals and helps direct the beam towards the receiver.
The new test may sound exciting, but don’t throw away your fancy new 5G phone just yet – 6G isn’t expected to be commercially available until about 2030.
