6.2 Gigabits per second, 15 meters have been sparked this week in Canada. Suddenly the 6G prototype, which developers of the University of California in Santa Barbara (UCSB) have developed together with Samsung Research. This shares the Sudkorean Group with. The scene of the 6G demonstration was the currently in Montreal IEEE conference for communication.
The digital radio signal was emitted in the Terahertz range (140 GHz) from a Phased Array antenna with 16 channels. The signal was handsome 2 gigahertz wide. This is 400 times a typical UMTS mobile signal (WCDMA). The aim is at 6g even a rough order wider radio signals. In this high frequency range, there is still a lot of free frequency spectrum.
To overhead in the Terahertz area can be sparked, especially fleet chips are required. Classic channels with silicon chips could not radiate energy with so high frequencies. UCSB has developed special bipolar transistors with multiple semiconductor materials to radiate a 140 GHz signal.
It never works without a ki
Phased array antennas enhanced strongly to the wireless signal to bundle, shape and direct in accurate directions (beamforming), which will be an essential prerequisite for 6G. The precise calibration of the beamforming is so complex that it has to be used for artificial intelligence: Ki-algorithms must calculate the best entry and exit brackets for direction rays and they drove them in the zigzag around objects and living beings or specifically to reflecting objects. In the demonstration in Montreal, algorithms from the Samsung laboratory have been used according to the message.

With 6G Samsung liked the 5G transfer speeds by about a factor of 50. At the same time, latencies should be reduced by 90 percent again. The Sudkoreans hope for first commercial 6G plants 2028 and stucco may already have 2030. To accelerate the development, the Prasident Sudkoreas and the United States of America have agreed to cooperate between the two countries in May.
