Electronic supplies info details information sheets 2022? In the past Wi-Fi technology, intercell co-channel interference (Co-Channel Interference,CCI) is another important factor affecting channel capacity. The core of CSMA/CA is to listen before you speak (listen before talk,LBT). The device monitors the wireless channel first and sends data without being occupied. In the case of multi-AP mesh networking (AP,Access Point, wireless access point), the equipment in the cell will listen to the interference signal of the cell adjacent to the same channel, causing the device to mistakenly think that the wireless channel of the cell is being occupied at this time, so stop transmitting. This kind of interference will significantly reduce the network capacity when the network is not optimized or the number of available channels is very small. As shown in the figure below, the four Wi-Fi AP are networked with three channels. However, since there are only three channels available, AP1 and AP2 have to be deployed on the same channel Channel 6, when the signal of AP2 is interference to the user equipment belonging to AP1-Overlapped Basic Service Set (OBSS, overlapping basic service units, which can be understood as overlapping cells with the same frequency).

On April 30th, the day after entering GW, the Nippon Keizai Shimbun published an article saying that Toyota and Daihatsu would not only suspend car production during and after the Golden week due to a chronic shortage of semiconductors. Toyota will close all 14 factories in Japan from April 30 to May 8, the article said. Among them, the Takaoka plant in Toyota City, Aichi Prefecture will stop production of some production lines until May 9, and the Fujisong plant with Toyota car body in Kariya City, Aichi Prefecture will stop production until May 16. In addition to the second Shiga plant, which had previously announced an extension of the shutdown, Dafa will also increase the number of plants at the Dafen first factory and the head office from April 30 to May 8, extending the number of days of shutdown. In addition, the Kyoto plant is scheduled to stop production from May 18 to 19.
In the early CPUs, the chip integration level was very low. The CPU was a single chip. It only integrated an arithmetic unit and a controller. It could only calculate and control. At this time, the internal capacity of the CPU was useless. Memory, the CPU left The memory cannot be calculated. Back then, there was no memory in the CPU because the memory could not be integrated, and others such as the serial port could not be integrated, so there was only a single CPU. If you need to use the serial port, you need to use a serial port controller chip outside the CPU. The PCB traces are connected to the CPU, and then the entire PCB board is composed of the CPU, and these peripheral chips is called a system board. This system board can communicate with another system board. The CPU communicates with another system through its serial port controller. The serial port controller on the board communicates, and functions such as the serial port controller cannot be integrated into the CPU chip. For example, if the LCD is also used here, it is necessary to add an LCD controller chip to the periphery and connect it to the CPU through wiring. A whole board composed of these chips is called a system board. These UART controllers and LCD controllers are called peripherals. Combining them with the CPU on one board is the function implemented by a current K60 chip, but they are integrated into a small chip. The peripherals here refer to the inside of the system board, the peripherals outside the CPU are called peripherals, the CPU is called the internals, and there are only arithmetic units and controllers inside, which are called internals.
