5G commercial operation has entered its seventh year, and now the industry is beginning to imagine 6G networks, which are expected to be commercialized in 2030, leaving only three or four years. For 6G, the current technical standards have not yet been finalized, but its speed will be 10-100 times faster than 5G, and can even reach 1Tbps. It will also integrate the air, sky, sea and ground, and will even natively support AI and the like. In short, there are many new technology highlights.
However, not all technology giants are optimistic about 6G. Samsung Networks CEO Kim Woo-jun recently expressed a pessimistic view in an interview, believing that 6G will not even be a real new generation. He previously said that 5G will be the last generation (wireless network technology standard).
Bruno Zerbib, Chief Technology Officer of Orange Telecom, also has a similar view,Using a higher spectrum does not mean it belongs to a new generation of technology, and they do not want to tie the spectrum to a technology generation.
Their attitude towards 6G can be mainly divided into two parts. One part is technical. Jin Yujun believes that 6G will actually use the same underlying technology OFDM (orthogonal frequency division multiplexing) as 4G and 5G, and it is not a brand-new technology.
Even if 6G uses higher frequency bands, such as increasing from the current 3.5GHz to 6GHz or even millimeter wave frequency bands, this is also a problem that will be solved in the 5G era.
Apart from technical disputes,There is a more serious problem in the 6G era, which requires greater investment.However, this problem is more serious. In the 5G era, operators have invested more than tens of billions. What is the result? None of the money has been returned.
In addition, in the 5G era, in addition to the impressive speed promotion of 1000Mbps, URLLC (ultra-reliable low-latency communications) and mMTC (massive machine-type communications) were previously highly publicized, connecting billions of massive devices, but these did not happen.
In general, the views of Samsung and operators have poured cold water on 6G. The technical experience has not actually upgraded and how to recover the huge investment are two key issues. These two problems have actually appeared on the current 5G network. Do you still remember how operators and network suppliers described the grand vision of 5G in the past few years? How does it compare to your current experience?
Of course, 6G will not stop developing because of this, but the time point mentioned in the original article will be delayed a lot, and the main capabilities will not be realized until 2037-2038.
