When the user equipment communicates with the AP1, because the equipment receives the interference signal of the AP2 with the same frequency, the user equipment will mistakenly think that the cell of the AP1 is being occupied by other devices in the cell at this time, so wait for the next time period to send. As a result, network performance is degraded. Not only multi-cell networking, this kind of interference problem will also occur when the Wi-Fi AP is very close. For example, although you have only one wireless AP in your home, if your next-door neighbor has an AP deployed on the same channel as you, CCI will also reduce the success rate of your device access. Sadly, most manufacturers put Wi-Fi AP’s default channel on the first channel when the device leaves the factory. In this way, the problem of interference is even more serious. If you find this problem, you might as well change the Wi-Fi AP channel at home, which will significantly reduce interference and increase Internet speed. The solution of Wi-Fi 6 is to distinguish the local cell from the interference cell by introducing BSS Coloring (Cell Color coding) technology into the MAC layer. In other words, when working on the same channel, the AP that interferes with each other will be distinguished by different color codes.
Then, as demand for cars picks up in the fall of 2020, Toyota Denso Renesa plans to order 28nm semiconductors from TSMC again, but there is no room to produce in-car semiconductors because TSMC lines are occupied by other semiconductors. Although the inventory in the autumn and winter of 2020 exceeded the limit, by 2021, inventory had bottomed out, coupled with the shortage of 28nm semiconductors, cars could not be made. 28nm is the last generation of planar transistors (FinFET from 16 / 14nm to 3D) (2) do not use self-aligned double pattern (SADP) (will use SADP from FinFET) (3) Renesas vertical integration (integrated equipment manufacturer IDM), for example, outsource production to FinFET from this generation. In short, 28nm semiconductors produced by TSMC and other contract factories have a good performance-to-price ratio, so many electronic devices, including automobiles, use this semiconductor. At the invitation of the Japanese government, the TSMC Kumamoto plant, which will begin operation in 2024, will also mainly produce such 28nm semiconductors.
In the onboard system shown in the figure above, the green rectangle represents the printed circuit board (PCB), and the small rectangles of various colors above represent various functional modules in the system, such as memory. The functions of these modules are implemented by independent silicon chips, and they are connected by metal traces on the PCB to finally form a complete system. The System-on-Chip refers to the realization of the functions of the entire system on a single silicon chip. The schematic diagram is as follows: As shown in the figure above, a system-on-a-chip (SoC) implements various functional modules such as storage, processing, logic, and interfaces in one chip, rather than requiring several different physical chips to be implemented like a system-on-board. Compared with system-on-board, SoC solutions are lower cost, enable faster and more secure data transfer between different system units, have higher overall system speed, lower power consumption, smaller physical size, and better reliability.
